Remove the MachineMove class.

2013-05-13T01:16:13Z

It was just a less powerful and more confusing version of MCCFIInstruction. A side effect is that, since MCCFIInstruction uses dwarf register numbers, calls to getDwarfRegNum are pushed out, which should allow further simplifications. I left the MachineModuleInfo::addFrameMove interface unchanged since this patch was already fairly big. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@181680 91177308-0d34-0410-b5e6-96231b3b80d8

Fix a bug in the MC asm parser evaluating expressions. It was treating:

A = 9 B = 3 * A - 2 * A + 1 as B = 3 * A - (2 * A + 1) rdar://13816516 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@181366 91177308-0d34-0410-b5e6-96231b3b80d8

MCStreamer: Also clear vector of W64UnwindInfos on reset().

Remove redundant check and use cached FrameArray values.

No functional change. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@181355 91177308-0d34-0410-b5e6-96231b3b80d8

[SystemZ] Update non-pic DWARF encodings

2013-05-06T17:28:30Z

As pointed out by Rafael Espindola, we should match the DWARF encodings produced by GCC in both pic and non-pic modes. This was not the case for the non-pic case. This patch changes all DWARF encodings to DW_EH_PE_absptr for the non-pic case, just like GCC does. The test case is updated to check for both variants. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@181222 91177308-0d34-0410-b5e6-96231b3b80d8

[SystemZ] Define DWARF encoding

2013-05-06T16:11:12Z

This is another patch in preparation for adding the SystemZ target. It defines the appropriate values for DWARF encodings; the intent is to be compatible with what GCC currently does on the target. Patch by Richard Sandiford. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@181201 91177308-0d34-0410-b5e6-96231b3b80d8

Add ArrayRef constructor from None, and do the cleanups that this constructor enables

[PowerPC] Parse platform-specifc variant kinds in AsmParser

2013-05-03T19:52:35Z

This patch adds support for PowerPC platform-specific variant kinds in MCSymbolRefExpr::getVariantKindForName, and also adds a test case to verify they are translated to the appropriate fixup type. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@181053 91177308-0d34-0410-b5e6-96231b3b80d8

Fix section relocation for SECTIONREL32 with immediate offset.

2013-04-25T19:27:05Z

Patch by Kai Nacke. This matches the gnu as output. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@180568 91177308-0d34-0410-b5e6-96231b3b80d8

Align the LD,compact_unwind section.

2013-04-24T03:11:14Z

I know what would be cool! We should align the compact unwind section because aligned data access is faster. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@180171 91177308-0d34-0410-b5e6-96231b3b80d8
