* Avoid illegal integer promotion in fastiselBob Wilson2013-11-151-7/+2
| | | | | | | | | | | | | | | | | Stop folding constant adds into GEP when the type size doesn't match. Otherwise, the adds' operands are effectively being promoted, changing the conditions of an overflow. Results are different when: sext(a) + sext(b) != sext(a + b) Problem originally found on x86-64, but also fixed issues with ARM and PPC, which used similar code. <rdar://problem/15292280> Patch by Duncan Exon Smith! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@194840 91177308-0d34-0410-b5e6-96231b3b80d8
* [Stackmap] Add AnyReg calling convention support for patchpoint intrinsic.Juergen Ributzka2013-11-081-0/+1
| | | | | | | | | | | | | | 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).

This is valid only if the related instructions are in that same basic block, otherwise we may reference variables that were not live accross basic blocks resulting in undefined virtual registers.

* Target/X86: Add explicit Win64 and System V/x86-64 calling conventions.Charles Davis2013-07-121-11/+14
| | | | | | | | | | | | | | | Summary: This patch adds explicit calling convention types for the Win64 and System V/x86-64 ABIs. This allows code to override the default, and use the Win64 convention on a target that wants to use SysV (and vice-versa). This is needed to implement the `ms_abi` and `sysv_abi` GNU attributes.

| | | | | | | | | | | | | Explicit references to %AH for an i8 remainder instruction can lead to references to %AH in a REX prefixed instruction, which causes things to blow up. Do the same thing in FastISel as we do for DAG isel and instead shift %AX right by 8 bits and then extract the 8-bit subreg from that result. rdar://14203849 http://llvm.org/bugs/show_bug.cgi?id=16105 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@185899 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | A FastISel optimization was causing us to emit no information for such parameters & when they go missing we end up emitting a different function type. By avoiding that shortcut we not only get types correct (very important) but also location information (handy) - even if it's only live at the start of a function & may be clobbered later.

* X86: use sub-register sequences for MOV*r0 operationsTim Northover2013-05-301-6/+25
| | | | | | | | | | | | 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

* Allow misaligned stores in x86 fast-isel.Derek Schuff2013-04-181-5/+0
| | | | | | | | | | | | In X86FastISel::X86SelectStore(), improperly aligned stores are rejected and handled by the DAG-based ISel. However, X86FastISel::X86SelectLoad() makes no such requirement. There doesn't appear to be an x86 architectural correctness issue with allowing potentially unaligned store instructions. This patch removes this restriction.

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.

| | | | | | | | | | | | | | | | | | | This shouldn't affect codegen for -O0 compiles as tail call markers are not emitted in unoptimized compiles. Testing with the external/internal nightly test suite reveals no change in compile time performance. Testing with -O1, -O2 and -O3 with fast-isel enabled did not cause any compile-time or execution-time failures. All tests were performed on my x86 machine. I'll monitor our arm testers to ensure no regressions occur there. In an upcoming clang patch I will be marking the objc_autoreleaseReturnValue and objc_retainAutoreleaseReturnValue as tail calls unconditionally. While it's theoretically true that this is just an optimization, it's an optimization that we very much want to happen even at -O0, or else ARC applications become substantially harder to debug.

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.

These commits also contained several problems that should really be addressed before they are re-committed. I have avoided reverting various cleanups to the DataLayout APIs that are reasonable to have moving forward in order to reduce the amount of churn, and minimize the number of commits that were reverted. I've also manually updated merge conflicts and manually arranged for the getIntPtrType function to stay in DataLayout and to be defined in a plausible way after this revert. Thanks to Duncan for working through this exact strategy with me, and Nick Lewycky for tracking down the really annoying crasher this triggered. (Test case to follow in its own commit.)
