2011-03-23Revert r128175.Andrew Trick
I'm backing this out for the second time. It was supposed to be fixed by r128164, but the mingw self-host must be defeating the fix. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@128181 91177308-0d34-0410-b5e6-96231b3b80d8
2011-03-23Cmp peephole optimization isn't always safe for signed arithmetics.Evan Cheng
int tries = INT_MAX; while (tries > 0) { tries--; } The check should be: subs r4, #1 cmp r4, #0 bgt LBB0_1 The subs can set the overflow V bit when r4 is INT_MAX+1 (which loop canonicalization apparently does in this case). cmp #0 would have cleared it while not changing the N and Z bits. Since BGT is dependent on the V bit, i.e. (N == V) && !Z, it is not safe to eliminate the cmp #0. rdar://9172742 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@128179 91177308-0d34-0410-b5e6-96231b3b80d8
2011-03-23PR9535: add support for splitting and scalarizing vector ISD::FP_ROUND.Eli Friedman

2011-03-23The high bit of a Thumb2 ADR's offset is stored in bit 26, not bit 25.Owen Anderson
This fixes 464.h264ref with the integrated assembler. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@128172 91177308-0d34-0410-b5e6-96231b3b80d8
2011-03-23Fix double-free of Module.Jim Grosbach
The ExecutionEngine constructor already added the module, so there's no need to call addModule() directly. Doing so causes a double-free of the Module at program termination. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@128171 91177308-0d34-0410-b5e6-96231b3b80d8

2011-03-23Ensure that def-side physreg copies are scheduled above any other usesAndrew Trick
so the scheduler can't create new interferences on the copies themselves. Prior to this fix the scheduler could get stuck in a loop creating copies. Fixes PR9509. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@128164 91177308-0d34-0410-b5e6-96231b3b80d8

2011-03-23Don't coalesce identical DBG_VALUE instructions prematurely.Jakob Stoklund Olesen
Each of these instructions may have a RegsClobberInsn entry that can't be ignored. Consecutive ranges are coalesced later when DwarfDebug::emitDebugLoc merges entries. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@128155 91177308-0d34-0410-b5e6-96231b3b80d8

2011-03-22Reapply r128045 and r128051 with fixes.Jakob Stoklund Olesen
This will extend the ranges of debug info variables in registers until they are clobbered. Fix 1: Don't mistake DBG_VALUE instructions referring to incoming arguments on the stack with DBG_VALUE instructions referring to variables in the frame pointer. This fixes the gdb test-suite failure. Fix 2: Don't trace through copies to physical registers setting up call arguments. These registers are call clobbered, and the source register is more likely to be a callee-saved register that can be extended through the call instruction. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@128114 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@128106 91177308-0d34-0410-b5e6-96231b3b80d8
2011-03-22A8.6.399 VSTM:Johnny Chen
VFP Load/Store Multiple Instructions used to embed the IA/DB addressing mode within the MC instruction; that has been changed so that now, for example, VSTMDDB_UPD and VSTMDIA_UPD are two instructions. Update the ARMDisassemblerCore.cpp's DisassembleVFPLdStMulFrm() to reflect the change. Also add a test case. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@128103 91177308-0d34-0410-b5e6-96231b3b80d8

2011-03-22Add simple arg passing to MC-JIT and support for exit() call.Jim Grosbach
Support argument passing simple, common, prototypes directly. More complicated scenarios will require building up a stub function, which the MC-JIT isn't set up to handle yet. Add Intercept.cpp, which is just a copy from ExecutionEngine/JIT for now, to handle looking looking up external symbol names. This probably more properly belongs as part of RuntimeDyld. It'll migrate there as things flesh out more fully. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@128090 91177308-0d34-0410-b5e6-96231b3b80d8
