2013-02-15Don't make assumptions about the mangling of static functions in extern "C"Rafael Espindola
blocks. We still don't have consensus if we should try to change clang or the standard, but llvm should work with compilers that implement the current standard and mangle those functions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@175267 91177308-0d34-0410-b5e6-96231b3b80d8

2013-02-04More MSan/ASan annotations.Evgeniy Stepanov
This change lets us bootstrap LLVM/Clang under ASan and MSan. It contains fixes for 2 issues: - X86JIT reads return address from stack, which MSan does not know is initialized. - bugpoint tests run binaries with RLIMIT_AS. This does not work with certain Sanitizers. We are no longer including config.h in Compiler.h with this change. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@174306 91177308-0d34-0410-b5e6-96231b3b80d8
2013-01-02Move all of the header files which are involved in modelling the LLVM IRChandler Carruth
into their new header subdirectory: include/llvm/IR. This matches the directory structure of lib, and begins to correct a long standing point of file layout clutter in LLVM. There are still more header files to move here, but I wanted to handle them in separate commits to make tracking what files make sense at each layer easier. The only really questionable files here are the target intrinsic tablegen files. But that's a battle I'd rather not fight today. I've updated both CMake and Makefile build systems (I think, and my tests think, but I may have missed something). I've also re-sorted the includes throughout the project. I'll be committing updates to Clang, DragonEgg, and Polly momentarily. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@171366 91177308-0d34-0410-b5e6-96231b3b80d8

2012-02-13Fix various issues (or do cleanups) found by enabling certain MSVC warnings.Ahmed Charles
- Use unsigned literals when the desired result is unsigned. This mostly allows unsigned/signed mismatch warnings to be less noisy even if they aren't on by default. - Remove misplaced llvm_unreachable. - Add static to a declaration of a function on MSVC x86 only. - Change some instances of calling a static function through a variable to simply calling that function while removing the unused variable. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@150364 91177308-0d34-0410-b5e6-96231b3b80d8

2009-12-15Change indirect-globals to use a dedicated allocIndirectGV. This lets usJeffrey Yasskin
remove start/finishGVStub and the BufferState helper class from the MachineCodeEmitter interface. It has the side-effect of not setting the indirect global writable and then executable on ARM, but that shouldn't be necessary. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@91464 91177308-0d34-0410-b5e6-96231b3b80d8
2009-11-23* Move stub allocation inside the JITEmitter, instead of exposing aJeffrey Yasskin
way for each TargetJITInfo subclass to allocate its own stubs. This means stubs aren't as exactly-sized anymore, but it lets us get rid of TargetJITInfo::emitFunctionStubAtAddr(), which lets ARM and PPC support the eager JIT, fixing http://llvm.org/PR4816. * Rename the JITEmitter's stub creation functions to describe the kind of stub they create. So far, all of them create lazy-compilation stubs, but they sometimes get used when far-call stubs are needed. Fixing http://llvm.org/PR5201 will involve fixing this. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@89715 91177308-0d34-0410-b5e6-96231b3b80d8
2009-11-23Allow more than one stub to be being generated at the same time.Jeffrey Yasskin
It's probably better in the long run to replace the indirect-GlobalVariable system. That'll be done after a subsequent patch. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@89708 91177308-0d34-0410-b5e6-96231b3b80d8
2009-11-16Make X86-64 in the Large model always emit 64-bit calls.Jeffrey Yasskin
The large code model is documented at http://www.x86-64.org/documentation/abi.pdf and says that calls should assume their target doesn't live within the 32-bit pc-relative offset that fits in the call instruction. To do this, we turn off the global-address->target-global-address conversion in X86TargetLowering::LowerCall(). The first attempt at this broke the lazy JIT because it can separate the movabs(imm->reg) from the actual call instruction. The lazy JIT receives the address of the movabs as a relocation and needs to record the return address from the call; and then when that call happens, it needs to patch the movabs with the newly-compiled target. We could thread the call instruction into the relocation and record the movabs<->call mapping explicitly, but that seems to require at least as much new complication in the code generator as this change. To fix this, we make lazy functions _always_ go through a call stub. You'd think we'd only have to force lazy calls through a stub on difficult platforms, but that turns out to break indirect calls through a function pointer. The right fix for that is to distinguish between calls and address-of operations on uncompiled functions, but that's complex enough to leave for someone else to do. Another attempt at this defined a new CALL64i pseudo-instruction, which expanded to a 2-instruction sequence in the assembly output and was special-cased in the X86CodeEmitter's emitInstruction() function. That broke indirect calls in the same way as above. This patch also removes a hack forcing Darwin to the small code model. Without far-call-stubs, the small code model requires things of the JITMemoryManager that the DefaultJITMemoryManager can't provide. Thanks to echristo for lots of testing! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@88984 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-15Change the marker byte for stubs from 0xcd to 0xce (another form ofDale Johannesen
interrupt instruction, which shouldn't arise any other way). 0xcd is also used by JITMemoryManager to initialize the buffer to garbage, which means it could appear following a noreturn call even when that is not a stub, confusing X86CompilationCallback2.

2009-02-18Add support to the JIT for true non-lazy operation. When a call to a functionNate Begeman
that has not been JIT'd yet, the callee is put on a list of pending functions to JIT. The call is directed through a stub, which is updated with the address of the function after it has been JIT'd. A new interface for allocating and updating empty stubs is provided. Add support for removing the ModuleProvider the JIT was created with, which would otherwise invalidate the JIT's PassManager, which is initialized with the ModuleProvider's Module. Add support under a new ExecutionEngine flag for emitting the infomration necessary to update Function and GlobalVariable stubs after JITing them, by recording the address of the stub and the name of the GlobalValue. This allows code to be copied from one address space to another, where libraries may live at different virtual addresses, and have the stubs updated with their new correct target addresses. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@64906 91177308-0d34-0410-b5e6-96231b3b80d8
