* Make the llvm mangler depend only on DataLayout.Rafael Espindola2014-01-03
| | | | | | | | | | | | | | Before this patch any program that wanted to know the final symbol name of a GlobalValue had to link with Target. This patch implements a compromise solution where the mangler uses DataLayout. This way, any tool that already links with Target (llc, clang) gets the exact behavior as before and new IR files can be mangled without linking with Target. With this patch the mangler is constructed with just a DataLayout and DataLayout is extended to include the information the Mangler needs. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@198438 91177308-0d34-0410-b5e6-96231b3b80d8

* Remove the isImplicitlyPrivate argument of getNameWithPrefix.Rafael Espindola2013-12-05
| | | | | | | | | | | | getSymbolWithGlobalValueBase use is to create a name of a new symbol based on the name of an existing GV. Assert that and then remove the last call to pass true to isImplicitlyPrivate. This gives the mangler API a 1:1 mapping from GV to names, which is what we need to drop the mangler dependency on the target (and use an extended datalayout instead). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@196472 91177308-0d34-0410-b5e6-96231b3b80d8

* Refactor a lot of patchpoint/stackmap related code to simplify and make itLang Hames2013-11-29
| | | | | | | | | | | | | | | | | | | | | | | | target independent. Most of the x86 specific stackmap/patchpoint handling was necessitated by the use of the native address-mode format for frame index operands. PEI has now been modified to treat stackmap/patchpoint similarly to DEBUG_INFO, allowing us to use a simple, platform independent register/offset pair for frame indexes on stackmap/patchpoints. Notes: - Folding is now platform independent and automatically supported. - Emiting patchpoints with direct memory references now just involves calling the TargetLoweringBase::emitPatchPoint utility method from the target's XXXTargetLowering::EmitInstrWithCustomInserter method. (See X86TargetLowering for an example). - No more ugly platform-specific operand parsers. This patch shouldn't change the generated output for X86. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@195944 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | | | | X86AsmPrinter::EmitInstruction, rather than X86MCInstLower::Lower. The aim is to improve the reusability of the X86MCInstLower class by making it more function-like. The X86::MORESTACK_RET_RESTORE_R10 pseudo broke the function model by emitting an extra instruction to the MCStreamer attached to the AsmPrinter. The patch should have no impact on generated code. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@194431 91177308-0d34-0410-b5e6-96231b3b80d8
* [Stackmap] Materialize the jump address within the patchpoint noop slide.Juergen Ributzka2013-11-09
| | | | | | | | | | | | | | | This patch moves the jump address materialization inside the noop slide. This enables patching of the materialization itself or its complete removal. This patch also adds the ability to define scratch registers that can be used safely by the code called from the patchpoint intrinsic. At least one scratch register is required, because that one is used for the materialization of the jump address. This patch depends on D2009.

* [Stackmap] Add AnyReg calling convention support for patchpoint intrinsic.Juergen Ributzka2013-11-08
| | | | | | | | | | | | | | The idea of the AnyReg Calling Convention is to provide the call arguments in registers, but not to force them to be placed in a paticular order into a specified set of registers. Instead it is up tp the register allocator to assign any register as it sees fit. The same applies to the return value (if applicable).

* X86: Stop LEA64_32r doing unspeakable things to its arguments.Tim Northover2013-06-10
| | | | | | | | | | | | Previously LEA64_32r went through virtually the entire backend thinking it was using 32-bit registers until its blissful illusions were cruelly snatched away by MCInstLower and 64-bit equivalents were substituted at the last minute. This patch makes it behave normally, and take 64-bit registers as sources all the way through. Previous uses (for 32-bit arithmetic) are accommodated via SUBREG_TO_REG instructions which make the types and classes agree properly. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@183693 91177308-0d34-0410-b5e6-96231b3b80d8

* X86: change MOV64ri64i32 into MOV32ri64Tim Northover2013-06-01
| | | | | | | | | | | | | | The MOV64ri64i32 instruction required hacky MCInst lowering because it was allocated as setting a GR64, but the eventual instruction ("movl") only set a GR32. This converts it into a so-called "MOV32ri64" which still accepts a (appropriate) 64-bit immediate but defines a GR32. This is then converted to the full GR64 by a SUBREG_TO_REG operation, thus keeping everyone happy. This fixes a typo in the opcode field of the original patch, which should make the legact JIT work again (& adds test for that problem). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@183068 91177308-0d34-0410-b5e6-96231b3b80d8

* X86: use sub-register sequences for MOV*r0 operationsTim Northover2013-05-30
| | | | | | | | | | | | Instead of having a bunch of separate MOV8r0, MOV16r0, ... pseudo-instructions, it's better to use a single MOV32r0 (which will expand to "xorl %reg, %reg") and obtain other sizes with EXTRACT_SUBREG and SUBREG_TO_REG. The encoding is smaller and partial register updates can sometimes be avoided. Until recently, this sequence was a barrier to rematerialization though. That should now be fixed so it's an appropriate time to make the change. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@182928 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | 32-bit writes on amd64 zero out the high bits of the corresponding 64-bit register. LLVM makes use of this for zero-extension, but until now relied on custom MCLowering and other code to fixup instructions. Now we have proper handling of sub-registers, this can be done by creating SUBREG_TO_REG instructions at selection-time. Should be no change in functionality. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@182921 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.

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.
