* Move getSymbol to TargetLoweringObjectFile.Rafael Espindola2013-10-29
| | | | | | This allows constructing a Mangler with just a TargetMachine. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@193630 91177308-0d34-0410-b5e6-96231b3b80d8
* [DebugInfo] Allow getDebugThreadLocalSymbol to return MCExprUlrich Weigand2013-07-02
| | | | | | | | | | | | | This allows getDebugThreadLocalSymbol to return a generic MCExpr instead of just a MCSymbolRefExpr. This is in preparation for supporting debug info for TLS variables on PowerPC, where we need to describe the variable location using a more complex expression than just MCSymbolRefExpr. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@185460 91177308-0d34-0410-b5e6-96231b3b80d8
* DebugInfo: PR14728: TLS supportDavid Blaikie2013-06-28
| | | | | | | | | | | | | | Based on GCC's output for TLS variables (OP_constNu, x@dtpoff, OP_lo_user), this implements debug info support for TLS in ELF. Verified that this output is correct/sufficient on Linux (using gold - if you're using binutils-ld, you'll need something with the fix for http://sourceware.org/bugzilla/show_bug.cgi?id=15685 in it). Support on non-ELF is sort of "arbitrary" at the moment - if Apple folks want to discuss (or just go ahead & implement) how this should work in MachO, etc, I'm open. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@185203 91177308-0d34-0410-b5e6-96231b3b80d8
* Move all of the header files which are involved in modelling the LLVM IRChandler Carruth2013-01-02
| | | | | | | | | | | | | | | | | | | | | 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
* Use the new script to sort the includes of every file under lib.Chandler Carruth2012-12-03
| | | | | | | | | | | | | | | | | Sooooo many of these had incorrect or strange main module includes. I have manually inspected all of these, and fixed the main module include to be the nearest plausible thing I could find. If you own or care about any of these source files, I encourage you to take some time and check that these edits were sensible. I can't have broken anything (I strictly added headers, and reordered them, never removed), but they may not be the headers you'd really like to identify as containing the API being implemented. Many forward declarations and missing includes were added to a header files to allow them to parse cleanly when included first. The main module rule does in fact have its merits. =] git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@169131 91177308-0d34-0410-b5e6-96231b3b80d8

* Move global variables in TargetMachine into new TargetOptions class. As an APINick Lewycky2011-12-02
| | | | | | | | | | | | | change, now you need a TargetOptions object to create a TargetMachine. Clang patch to follow. One small functionality change in PTX. PTX had commented out the machine verifier parts in their copy of printAndVerify. That now calls the version in LLVMTargetMachine. Users of PTX who need verification disabled should rely on not passing the command-line flag to enable it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@145714 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | | | | | | | give it a bit more responsibility. Also implement it for MachO. If hacked to use cfi, 32 bit MachO will produce .cfi_personality 155, L___gxx_personality_v0$non_lazy_ptr and 64 bit will produce .cfi_presonality ___gxx_personality_v0 The general idea is that .cfi_personality gets passed the final symbol. It is up to codegen to produce it if using indirect representation (like 32 bit MachO), but it is up to MC to decide which relocations to create. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@130341 91177308-0d34-0410-b5e6-96231b3b80d8
