2011-08-19Don't treat a partial <def,undef> operand as a read.Jakob Stoklund Olesen
Normally, a partial register def is treated as reading the super-register unless it also defines the full register like this: %vreg110:sub_32bit<def> = COPY %vreg77:sub_32bit, %vreg110<imp-def> This patch also uses the <undef> flag on partial defs to recognize non-reading operands: %vreg110:sub_32bit<def,undef> = COPY %vreg77:sub_32bit This fixes a subtle bug in RegisterCoalescer where LIS->shrinkToUses would treat a coalesced copy as still reading the register, extending the live range artificially. My test case only works when I disable DCE so a dead copy is left for RegisterCoalescer, so I am not including it. <rdar://problem/9967101> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@138018 91177308-0d34-0410-b5e6-96231b3b80d8
2011-08-19Track a retain+release nesting level independently of theDan Gohman
known-incremented level, because the two concepts can be used to prove the saftey of a retain+release removal in different ways. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@138016 91177308-0d34-0410-b5e6-96231b3b80d8
2011-08-19Intelligently split the landing pad block.Bill Wendling
We have to be careful when splitting the landing pad block, because the landingpad instruction is required to remain as the first non-PHI of an invoke's unwind edge. To retain this, we split the block into two blocks, moving the predecessors within the loop to one block and the remaining predecessors to the other. The landingpad instruction is cloned into the new blocks. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@138015 91177308-0d34-0410-b5e6-96231b3b80d8
2011-08-19Add SplitLandingPadPredecessors().Bill Wendling
SplitLandingPadPredecessors is similar to SplitBlockPredecessors in that it splits the current block and attaches a set of predecessors to the new basic block. However, it differs from SplitBlockPredecessors in that it's specifically designed to handle landing pad blocks. Two new basic blocks are created: one that is has the vector of predecessors as its predecessors and one that has the remaining predecessors as its predecessors. Those two new blocks then receive a cloned copy of the landingpad instruction from the original block. The landingpad instructions are joined in a PHI, etc. Like SplitBlockPredecessors, it updates the LLVM IR, AliasAnalysis, DominatorTree, DominanceFrontier, LoopInfo, and LCCSA analyses. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@138014 91177308-0d34-0410-b5e6-96231b3b80d8
2011-08-18Re-encoded 128-bit AVX versions of SQRT, RSQRT, RCP have 3 operandsBruno Cardoso Lopes
instead of 2. They were already defined this way in their regular version, but not for the intrinsics versions (*_Int), and that would work for assembly emission but not for object code, since a MachineOperand would be missing. This commit fix PR10697. Also removed the {VSQRT,VRSQRT,VRCP}r_Int forms and match the intrinsic via INSERT_SUBREG+EXTRACT_SUBREG patterns. The same couldn't be done for memory versions because sse_load_f32/sse_load_f64 operand need special handling and don't work like regular "addr" operands. There are right now 114 "*_Int" and 98 "Int_*" forms! I'm slowly removing them as I step through, but hope we can get rid of these someday, they are really annoying :) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@138012 91177308-0d34-0410-b5e6-96231b3b80d8

2011-08-18Add NativeClient operating system support.Ivan Krasin
This patch adds support of NativeClient (*-*-nacl) OS support to LLVM. It's already supported in autoconf/config.sub. The motivation for this change is to start upstreaming PNaCl work. The whole set of patches include llvm backends (i686, x86_64, ARM), llvm-gcc (probably, would not be upstreamed because it's deprecated) and clang (the work has been just started, the amount of changes is going to be low and the most of the work is expected to be done close to the mainline). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@138005 91177308-0d34-0410-b5e6-96231b3b80d8

2011-08-18ARM Thumb blx instruction fixup has same data range as bl.Jim Grosbach
These fixups are handled poorly in general, and should have a single contiguous range of bits per fixup type, but that's not how they're currently organized, so for now in complex ones like for blx, we just tell the emitter it's OK for the fixup to munge any bit it wants. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@137947 91177308-0d34-0410-b5e6-96231b3b80d8
