First of all, this is a bunch of c++ * crap. Sorry if this is not that readable. Anyway, the goal here is to take * GenIR code (i.e. the very regular, very RISC IR) and to produce GenISA with * virtual registers (i.e. regular GenIR registers). * * Overall idea: * ============= * * There is a lot of papers and research about that but I tried to keep it * simple. No dynamic programming, nothing like this. Just a recursive maximal * munch. * * Basically, the code is executed per basic block from bottom to top. Patterns * of GenIR instructions are defined and each instruction is matched against the * best pattern i.e. the pattern that catches the largest number of * instructions. Once matched, a sequence of instructions is output. * * Each instruction the match depends on is then marked as "root" i.e. we * indicate that each of these instructions must be generated: we indeed need their * destinations for the next instructions (remember that we generate the code in * reverse order) * * Patterns: * ========= * * There is a lot of patterns and I did not implement all of them obviously. I * just quickly gather the complete code to make pattern implementation kind of * easy. This is pretty verbose to add a pattern but it should be not too hard * to add new ones. * * To create and register patterns, I just abused C++ pre-main. A bunch of * patterns is then created and sorted per opcode (i.e. the opcode of the root * of the pattern): this creates a library of patterns that may be used in * run-time. * * Predication / Masking and CFG linearization * =========================================== * * The current version is based on an unfortunate choice. Basically, the problem * to solve is how to map unstructured branches (i.e. regular gotos) onto Gen. * Gen has a native support for structured branches (if/else/endif/while...) but * nothing really native for unstructured branches. * * The idea we implemented is simple. We stole one flag register (here f0.0) to * mask all the instructions (and only activate the proper SIMD lanes) and we * use the CFG linearization technique to properly handle the control flow. This * is not really good for one particular reason: Gen instructions must use the * *same* flag register for the predicates (used for masking) and the * conditional modifier (used as a destination for CMP). This leads to extra * complications with compare instructions and select instructions. Basically, * we need to insert extra MOVs. * * Also, there is some extra kludge to handle the predicates for JMPI. * * TODO: * ===== * * Sadly, I recreated here a new DAG class. This is just a bad idea since we * already have the DAG per basic block with the Function graph i.e. the * complete graph of uses and definitions. I think we should be able to save a * lot of code here if we can simply reuse the code from UD / DU chains. * * Finally, cross-block instruction selection is quite possible with this simple * approach. Basically, instructions from dominating blocks could be merged and * matched with other instructions in the dominated block. This leads to the * interesting approach which consists in traversing the dominator tree in post * order * * We already use if/endif to enclose each basic block. We will continue to identify * those blocks which could match to structured branching and use pure structured * instruction to handle them completely. */ #include "backend/gen_insn_selection.hpp" #include "backend/gen_context.hpp" #include "ir/function.hpp" #include "ir/liveness.hpp" #include "ir/profile.hpp" #include "sys/cvar.hpp" #include "sys/vector.hpp" #include <algorithm> #include <climits> namespace gbe { /////////////////////////////////////////////////////////////////////////// // Helper functions /////////////////////////////////////////////////////////////////////////// uint32_t getGenType(ir::Type type) { using namespace ir; switch (type) { case TYPE_BOOL: return GEN_TYPE_UW; case TYPE_S8: return GEN_TYPE_B; case TYPE_U8: return GEN_TYPE_UB; case TYPE_S16: return GEN_TYPE_W; case TYPE_U16: return GEN_TYPE_UW; case TYPE_S32: return GEN_TYPE_D; case TYPE_U32: return GEN_TYPE_UD; case TYPE_S64: return GEN_TYPE_L; case TYPE_U64: return GEN_TYPE_UL; case TYPE_FLOAT: return GEN_TYPE_F; case TYPE_DOUBLE: return GEN_TYPE_DF; default: NOT_SUPPORTED; return GEN_TYPE_F; } } ir::Type getIRType(uint32_t genType) { using namespace ir; switch (genType) { case GEN_TYPE_B: return TYPE_S8; case GEN_TYPE_UB: return TYPE_U8; case GEN_TYPE_W: return TYPE_S16; case GEN_TYPE_UW: return TYPE_U16; case GEN_TYPE_D: return TYPE_S32; case GEN_TYPE_UD: return TYPE_U32; case GEN_TYPE_L: return TYPE_S64; case GEN_TYPE_UL: return TYPE_U64; case GEN_TYPE_F: return TYPE_FLOAT; case GEN_TYPE_DF: return TYPE_DOUBLE; default: NOT_SUPPORTED; return TYPE_FLOAT; } } uint32_t getGenCompare(ir::Opcode opcode, bool inverse = false) { using namespace ir; switch (opcode) { case OP_LE: return (!inverse) ?

First of all, this is a bunch of c++ * crap. Sorry if this is not that readable. Anyway, the goal here is to take * GenIR code (i.e. the very regular, very RISC IR) and to produce GenISA with * virtual registers (i.e. regular GenIR registers). * * Overall idea: * ============= * * There is a lot of papers and research about that but I tried to keep it * simple. No dynamic programming, nothing like this. Just a recursive maximal * munch. * * Basically, the code is executed per basic block from bottom to top. Patterns * of GenIR instructions are defined and each instruction is matched against the * best pattern i.e. the pattern that catches the largest number of * instructions. Once matched, a sequence of instructions is output. * * Each instruction the match depends on is then marked as "root" i.e. we * indicate that each of these instructions must be generated: we indeed need their * destinations for the next instructions (remember that we generate the code in * reverse order) * * Patterns: * ========= * * There is a lot of patterns and I did not implement all of them obviously. I * just quickly gather the complete code to make pattern implementation kind of * easy. This is pretty verbose to add a pattern but it should be not too hard * to add new ones. * * To create and register patterns, I just abused C++ pre-main. A bunch of * patterns is then created and sorted per opcode (i.e. the opcode of the root * of the pattern): this creates a library of patterns that may be used in * run-time. * * Predication / Masking and CFG linearization * =========================================== * * The current version is based on an unfortunate choice. Basically, the problem * to solve is how to map unstructured branches (i.e. regular gotos) onto Gen. * Gen has a native support for structured branches (if/else/endif/while...) but * nothing really native for unstructured branches. * * The idea we implemented is simple. We stole one flag register (here f0.0) to * mask all the instructions (and only activate the proper SIMD lanes) and we * use the CFG linearization technique to properly handle the control flow. This * is not really good for one particular reason: Gen instructions must use the * *same* flag register for the predicates (used for masking) and the * conditional modifier (used as a destination for CMP). This leads to extra * complications with compare instructions and select instructions. Basically, * we need to insert extra MOVs. * * Also, there is some extra kludge to handle the predicates for JMPI. * * TODO: * ===== * * Sadly, I recreated here a new DAG class. This is just a bad idea since we * already have the DAG per basic block with the Function graph i.e. the * complete graph of uses and definitions. I think we should be able to save a * lot of code here if we can simply reuse the code from UD / DU chains. * * Finally, cross-block instruction selection is quite possible with this simple * approach. Basically, instructions from dominating blocks could be merged and * matched with other instructions in the dominated block. This leads to the * interesting approach which consists in traversing the dominator tree in post * order * * We already use if/endif to enclose each basic block.

Pearce and Paul H.J. Kelly This is the MNR algorithm, which was first introduced by A. Marchetti-Spaccamela, U. Nanni and H. Rohnert in "Maintaining a topological order under edge insertions". Short description of the algorithm: Topological ordering, ord, of a DAG maps each node to a topological index so that for all edges X->Y it is the case that ord(X) < ord(Y). This means that if there is a path from the node X to the node Z, then ord(X) < ord(Z). This property can be used to check for reachability of nodes: if Z is reachable from X, then an insertion of the edge Z->X would create a cycle. The algorithm first computes a topological ordering for the DAG by initializing the Index2Node and Node2Index arrays and then tries to keep the ordering up-to-date after edge insertions by reordering the DAG. On insertion of the edge X->Y, the algorithm first marks by calling DFS the nodes reachable from Y, and then shifts them using Shift to lie immediately after X in Index2Node. */ /// InitDAGTopologicalSorting - create the initial topological /// ordering from the DAG to be scheduled. void InitDAGTopologicalSorting(); /// DFS - make a DFS traversal and mark all nodes affected by the /// edge insertion.

Pearce and Paul H.J. Kelly This is the MNR algorithm, which was first introduced by A. Marchetti-Spaccamela, U. Nanni and H. Rohnert in "Maintaining a topological order under edge insertions". Short description of the algorithm: Topological ordering, ord, of a DAG maps each node to a topological index so that for all edges X->Y it is the case that ord(X) < ord(Y). This means that if there is a path from the node X to the node Z, then ord(X) < ord(Z). This property can be used to check for reachability of nodes: if Z is reachable from X, then an insertion of the edge Z->X would create a cycle. The algorithm first computes a topological ordering for the DAG by initializing the Index2Node and Node2Index arrays and then tries to keep the ordering up-to-date after edge insertions by reordering the DAG. On insertion of the edge X->Y, the algorithm first marks by calling DFS the nodes reachable from Y, and then shifts them using Shift to lie immediately after X in Index2Node. */ /// InitDAGTopologicalSorting - create the initial topological /// ordering from the DAG to be scheduled. void InitDAGTopologicalSorting(); /// DFS - make a DFS traversal and mark all nodes affected by the /// edge insertion.

This is the same /// usage as .a file in Unix. /// /// - For dynamic linking: An archive file in this use case contains pseudo /// .obj files to describe exported symbols of a DLL. Each pseudo .obj file /// in an archive has a name of an exported symbol and a DLL filename from /// which the symbol can be imported. When you link a DLL on Windows, you /// pass the name of the .lib file for the DLL instead of the DLL filename /// itself. That is the Windows way of linking against a shared library. /// /// This file contains a function to handle the pseudo object file. /// /// Windows Loader and Import Address Table /// ======================================= /// /// Windows supports a GOT-like mechanism for DLLs. The executable using DLLs /// contains a list of DLL names and list of symbols that need to be resolved by /// the loader. Windows loader maps the executable and all the DLLs to memory, /// resolves the symbols referencing items in DLLs, and updates the import /// address table (IAT) in memory. The IAT is an array of pointers to all of the /// data or functions in DLL referenced by the executable. You cannot access /// items in DLLs directly. They have to be accessed through an extra level of /// indirection. /// /// So, if you want to access an item in DLL, you have to go through a /// pointer. How do you actually do that? You need a symbol for a pointer in the /// IAT. For each symbol defined in a DLL, a symbol with "__imp_" prefix is /// exported from the DLL for an IAT entry. For example, if you have a global /// variable "foo" in a DLL, a pointer to the variable is available as /// "_imp__foo". The IAT is an array of _imp__ symbols. /// /// Is this OK? That's not that complicated. Because items in a DLL are not /// directly accessible, you need to access through a pointer, and the pointer /// is available as a symbol with _imp__ prefix. /// /// Note 1: Although you can write code with _imp__ prefix, today's compiler and /// linker let you write code as if there's no extra level of indirection. /// That's why you haven't seen lots of _imp__ in your code. A variable or a /// function declared with "dllimport" attribute is treated as an item in a DLL, /// and the compiler automatically mangles its name and inserts the extra level /// of indirection when accessing the item. Here are some examples: /// /// __declspec(dllimport) int var_in_dll; /// var_in_dll = 3; // is equivalent to *_imp__var_in_dll = 3; /// /// __declspec(dllimport) int fn_in_dll(void); /// fn_in_dll(); // is equivalent to (*_imp__fn_in_dll)(); /// /// It's just the compiler rewrites code for you so that you don't need to /// handle the indirection youself. /// /// Note 2: __declspec(dllimport) is mandatory for data but optional for /// function. For a function, the linker creates a jump table with the original /// symbol name, so that the function is accessible without _imp__ prefix. The /// same function in a DLL can be called through two different symbols if it's /// not dllimport'ed. /// /// (*_imp__fn)() /// fn() /// /// The above functions do the same thing. fn's content is a JMP instruction to /// branch to the address pointed by _imp__fn. The latter may be a little bit /// slower than the former because it will execute the extra JMP instruction, but /// that's usually negligible. /// /// If a function is dllimport'ed, which is usually done in a header file, /// mangled name will be used at compile time so the jump table will not be /// used. /// /// Because there's no way to hide the indirection for data access at link time, /// data has to be accessed through dllimport'ed symbols or explicit _imp__ /// prefix. /// /// Creating Atoms for the Import Address Table /// =========================================== /// /// The function in this file reads a pseudo object file and creates at most two /// atoms.

When you link a DLL on Windows, you /// pass the name of the .lib file for the DLL instead of the DLL filename /// itself. That is the Windows way of linking against a shared library. /// /// This file contains a function to handle the pseudo object file. /// /// Windows Loader and Import Address Table /// ======================================= /// /// Windows supports a GOT-like mechanism for DLLs. The executable using DLLs /// contains a list of DLL names and list of symbols that need to be resolved by /// the loader. Windows loader maps the executable and all the DLLs to memory, /// resolves the symbols referencing items in DLLs, and updates the import /// address table (IAT) in memory. The IAT is an array of pointers to all of the /// data or functions in DLL referenced by the executable. You cannot access /// items in DLLs directly. They have to be accessed through an extra level of /// indirection. /// /// So, if you want to access an item in DLL, you have to go through a /// pointer. How do you actually do that? You need a symbol for a pointer in the /// IAT. For each symbol defined in a DLL, a symbol with "__imp_" prefix is /// exported from the DLL for an IAT entry. For example, if you have a global /// variable "foo" in a DLL, a pointer to the variable is available as /// "_imp__foo". The IAT is an array of _imp__ symbols. /// /// Is this OK? That's not that complicated. Because items in a DLL are not /// directly accessible, you need to access through a pointer, and the pointer /// is available as a symbol with _imp__ prefix. /// /// Note 1: Although you can write code with _imp__ prefix, today's compiler and /// linker let you write code as if there's no extra level of indirection. /// That's why you haven't seen lots of _imp__ in your code. A variable or a /// function declared with "dllimport" attribute is treated as an item in a DLL, /// and the compiler automatically mangles its name and inserts the extra level /// of indirection when accessing the item. Here are some examples: /// /// __declspec(dllimport) int var_in_dll; /// var_in_dll = 3; // is equivalent to *_imp__var_in_dll = 3; /// /// __declspec(dllimport) int fn_in_dll(void); /// fn_in_dll(); // is equivalent to (*_imp__fn_in_dll)(); /// /// It's just the compiler rewrites code for you so that you don't need to /// handle the indirection youself. /// /// Note 2: __declspec(dllimport) is mandatory for data but optional for /// function. For a function, the linker creates a jump table with the original /// symbol name, so that the function is accessible without _imp__ prefix. The /// same function in a DLL can be called through two different symbols if it's /// not dllimport'ed. /// /// (*_imp__fn)() /// fn() /// /// The above functions do the same thing. fn's content is a JMP instruction to /// branch to the address pointed by _imp__fn. The latter may be a little bit /// slower than the former because it will execute the extra JMP instruction, but /// that's usually negligible. /// /// If a function is dllimport'ed, which is usually done in a header file, /// mangled name will be used at compile time so the jump table will not be /// used. /// /// Because there's no way to hide the indirection for data access at link time, /// data has to be accessed through dllimport'ed symbols or explicit _imp__ /// prefix. /// /// Idata Sections in the Pseudo Object File /// ======================================== /// /// The object file created by cl.exe has several sections whose name starts /// with ".idata$" followed by a number. The contents of the sections seem the /// fragments of a complete ".idata" section. These sections has relocations for /// the data referenced from the idata secton. Generally, the linker discards /// "$" and all characters that follow from the section name and merges their /// contents to one section. So, it looks like if everything would work fine, /// the idata section would naturally be constructed without having any special /// code for doing that. /// /// However, the LLD linker cannot do that. An idata section constructed in that /// way was never be in valid format. We don't know the reason yet. Our /// assumption on the idata fragment could simply be wrong, or the LLD linker is /// not powerful enough to do the job. Meanwhile, we construct the idata section /// ourselves. All the "idata$" sections in the pseudo object file are currently /// ignored. /// /// Creating Atoms for the Import Address Table /// =========================================== /// /// The function in this file reads a pseudo object file and creates at most two /// atoms. One is a shared library atom for _imp__ symbol. The another is a /// defined atom for the JMP instruction if the symbol is for a function. /// //===----------------------------------------------------------------------===// #define DEBUG_TYPE "ReaderImportHeader" #include "Atoms.h" #include "lld/Core/File.h" #include "lld/Core/Error.h" #include "lld/Core/SharedLibraryAtom.h" #include "llvm/ADT/ArrayRef.h" #include "llvm/Object/COFF.h" #include "llvm/Support/Casting.h" #include "llvm/Support/COFF.h" #include "llvm/Support/Debug.h" #include "llvm/Support/Endian.h" #include "llvm/Support/ErrorHandling.h" #include "llvm/Support/Memory.h" #include "llvm/Support/MemoryBuffer.h" #include "llvm/Support/raw_ostream.h" #include "llvm/Support/system_error.h" #include <map> #include <vector> #include <cstring> using namespace lld; using namespace llvm; namespace lld { namespace coff { namespace { /// The defined atom for jump table. class FuncAtom : public COFFLinkerInternalAtom { public: FuncAtom(const File &file, StringRef symbolName) : COFFLinkerInternalAtom(file, std::vector<uint8_t>(rawContent), symbolName) {} virtual uint64_t ordinal() const { return 0; } virtual Scope scope() const { return scopeGlobal; } virtual ContentType contentType() const { return typeCode; } virtual Alignment alignment() const { return Alignment(1); } virtual ContentPermissions permissions() const { return permR_X; } private: static std::vector<uint8_t> rawContent; }; // MSVC doesn't seem to like C++11 initializer list, so initialize the // vector from an array. namespace { uint8_t FuncAtomContent[] = { 0xff, 0x25, 0x00, 0x00, 0x00, 0x00, // jmp *0x0 0x90, 0x90 // nop; nop }; } // anonymous namespace std::vector<uint8_t> FuncAtom::rawContent( FuncAtomContent, FuncAtomContent + sizeof(FuncAtomContent)); class FileImportLibrary : public File { public: FileImportLibrary(const TargetInfo &ti, std::unique_ptr<llvm::MemoryBuffer> mb, llvm::error_code &ec) : File(mb->getBufferIdentifier(), kindSharedLibrary), _targetInfo(ti) { const char *buf = mb->getBufferStart(); const char *end = mb->getBufferEnd(); // The size of the string that follows the header. uint32_t dataSize = *reinterpret_cast<const support::ulittle32_t *>( buf + offsetof(COFF::ImportHeader, SizeOfData)); // Check if the total size is valid. if (end - buf != sizeof(COFF::ImportHeader) + dataSize) { ec = make_error_code(native_reader_error::unknown_file_format); return; } uint16_t hint = *reinterpret_cast<const support::ulittle16_t *>( buf + offsetof(COFF::ImportHeader, OrdinalHint)); StringRef symbolName(buf + sizeof(COFF::ImportHeader)); StringRef dllName(buf + sizeof(COFF::ImportHeader) + symbolName.size() + 1); // TypeInfo is a bitfield.

SetCC instructions are converted from <,>,<=,>= to ==,!= if possible // 4. All SetCC instructions on boolean values are replaced with logical ops // 5. add X, X is represented as (X*2) => (X << 1) // 6.

used, the broker must be started with options '-key' and '-cert'. * Both these two options have a file path associated to it: * -key: path to a file containing the private key for the server * -cert: path to a file containing a certificate describing the server in human readable tokens * * These files are generated before starting the broker: * * o private key: * % openssl genrsa -out server.key 1024 * * o certificate: * % openssl req -days 365 -out server.pem -new -x509 -key server.key * * After creating these two files, the context broker can be started like this: * % contextBroker -fg -https -key server.key -cert server.pem * * The clients need to use the 'server.pem' file in the request: * curl --cacert server.pem * * * To override the security added with the certificate, curl can

**************************************************************************** * * Some notes on HTTPS * * Lots of info found in http://www.gnu.org/software/libmicrohttpd/tutorial.html * * When https is used, the broker must be started with options '-key' and '-cert'. * Both these two options have a file path associated to it: * -key: path to a file containing the private key for the server * -cert: path to a file containing a certificate describing the server in human readable tokens * * These files are generated before starting the broker: * * o private key: * % openssl genrsa -out server.key 1024 * * o certificate: * % openssl req -days 365 -out server.pem -new -x509 -key server.key * * After creating these two files, the context broker can be started like this: * % contextBroker -fg -https -key server.key -cert server.pem * * The clients need to use the 'server.pem' file in the request: * curl --cacert server.pem * * * To override the security added with the certificate, curl can always be called using the * CLI option '--insecure'. */ #include <stdio.h> #include <unistd.h> // getppid, for, setuid, etc. #include <string.h> #include <fcntl.h> // open #include <sys/types.h>

A particular example of this is QTextCodec subclasses which automatically gets put into a global static list and are cleaned up on shutdown. Since we can't access the JNI environment at this point, we need to make sure we don't try to call disposed() or anything, as any attempt at using the JNIEnv pointer will cause a crash. Task 141944.
