git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@119793 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@119792 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-19Change some methods in MCDwarf.cpp to be able to handle an arbitraryRafael Espindola
MCStreamer instead of just MCObjectStreamer. Address changes cannot be as efficient as we have to use DW_LNE_set_addres, but at least most of the logic is shared. This will be used so that, with CodeGen still using EmitDwarfLocDirective, llvm-gcc is able to produce debug_line sections without needing an assembler that supports .loc. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@119777 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-19Add MC encodings for some Thumb instructions. Test for a few of them. The "bxBill Wendling
lr" instruction cannot be tested just yet. It requires matching a "condition code", but adding one of those makes things go south quickly... git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@119774 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@119761 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-18Fix .o emission of ARM movt/movw. MCSymbolRefExpr::VK_ARM_(HI||LO)16 for the ↵Jason W Kim
.o path now works for ARM. Note: lo16AllZero remains in ARMInstrInfo.td - It can be factored out when Thumb movt is repaired. Existing tests cover this update. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@119760 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-18Fix encodings for pkhbt, and fix some tests where I accidentally tested ARM ↵Owen Anderson
mode instead of Thumb2. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@119755 91177308-0d34-0410-b5e6-96231b3b80d8

2010-11-18Fix bug in DAGCombiner for ARM that was trying to do a ShiftCombine on ↵Tanya Lattner
illegal types (vector should be split first). Added test case. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@119749 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-18Don't allocate the SmallVector of Registers. It gets messy figuring out whoBill Wendling
should delete what when the object gets copied around. It's also making valgrind upset. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@119747 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-18Provide Thumb2 encodings for mov's that come from MOVCC SDNodes.Owen Anderson
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@119744 91177308-0d34-0410-b5e6-96231b3b80d8

2010-11-18Move hasFP() and few related hooks to TargetFrameInfo.Anton Korobeynikov
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@119740 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-18Split up ARM LowerShift function.Bob Wilson
This function was being called from two different places for completely unrelated reasons. During type legalization, it was called to expand 64-bit shift operations. During operation legalization, it was called to handle Neon vector shifts. The vector shift code was not written to check for illegal types, since it was assumed to be only called after type legalization. Fixed this by splitting off the 64-bit shift expansion into a separate function. I don't have a particular testcase for this; I just noticed it by inspection. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@119738 91177308-0d34-0410-b5e6-96231b3b80d8

2010-11-18Rewrite stack callee saved spills and restores to use push/pop instructions.Eric Christopher
Remove movePastCSLoadStoreOps and associated code for simple pointer increments. Update routines that depended upon other opcodes for save/restore. Adjust all testcases accordingly. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@119725 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-18ARMPseudoInst instructions should default to being considered a single 4-byteJim Grosbach
instruction. Any that may be expanded otherwise by MC lowering should override this value. rdar://8683274 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@119713 91177308-0d34-0410-b5e6-96231b3b80d8

sahf movl 344(%rdi),%r14d we used to produce: t.s:2:1: error: unexpected token in argument list ^ we now produce: t.s:1:11: error: unexpected token in argument list sahf movl 344(%rdi),%r14d ^ rdar://8581401 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@119676 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-18Change CodeGen to use .loc directives. This produces a lot more readable outputRafael Espindola
and testing is easier. A good example is the unknown-location.ll test that now can just look for ".loc 1 0 0". We also don't use a DW_LNE_set_address for every address change anymore. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@119613 91177308-0d34-0410-b5e6-96231b3b80d8

2010-11-18ARM PseudoInst instructions don't need or use an assembler string. Get rid ofJim Grosbach
the operand to the pattern. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@119607 91177308-0d34-0410-b5e6-96231b3b80d8

2010-11-17Clean up LEApcrel instuction(s) a bit. It's not really a Pseudo, so don't markJim Grosbach
it as such. Add some encoding information. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@119588 91177308-0d34-0410-b5e6-96231b3b80d8

2010-11-17Change ARMGlobalMerge to keep BSS globals in separate pools.Bob Wilson
This completes the fixes for Radar 8673120. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@119566 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-17Fix ARMGlobalMerge pass to check if globals are entirely within range.Bob Wilson
It is generally not sufficient to check if the starting offset is in range of the maximum offset that can be efficiently used for the target. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@119565 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-17Change the symbol for merged globals from "merged" to "_MergedGlobals".Bob Wilson
This makes it more clear that the symbol is an internal, compiler-generated name and gives a little more description about its contents. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@119564 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-17Fix the ARMGlobalMerge pass to look at variable sizes instead of pointer sizes.Bob Wilson
It was mistakenly looking at the pointer type when checking for the size of global variables. This is a partial fix for Radar 8673120. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@119563 91177308-0d34-0410-b5e6-96231b3b80d8
