Eli Friedman 8a15a5aa93 PR10998: It is not legal to sink an instruction past the terminator of a block; make sure we don't do that.

Owen Anderson 4916840eb8 Teach the Thumb2 AsmParser to accept pre-indexed loads/stores with an offset of #-0.

Jakob Stoklund Olesen 2056d15bd9 Also match negative offsets for addrmode3 and addrmode5. 
Math is hard, and isScaledConstantInRange() always returned false for
negative constants.  It was doing unsigned division of negative numbers
before casting back to signed.

Owen Anderson 737beaf86d Post-index loads/stores in still need to print the post-indexed immediate, even if it's zero, to distinguish them from non-post-indexed instructions.

Owen Anderson 987a878946 Reapply r140412 (Thumb2 reg-reg loads cannot target SP or PC), with invalid testcases updated.

Eli Friedman 87c844cdf8 PR10991: make fast-isel correctly check whether accessing a global through an alias involves thread-local storage. (I'm not entirely sure how this is supposed to work, but this patch makes fast-isel consistent with the normal isel path.)

Duncan Sands 0e4fcb8e3b Synthesize SSE3/AVX 128 bit horizontal add/sub instructions from 
floating point add/sub of appropriate shuffle vectors.  Does not
synthesize the 256 bit AVX versions because they work differently.

Owen Anderson fbe52c0192 Turns out that Thumb2 ADR doesn't need special printing like LDR does. Fix other test failures I caused.

Owen Anderson f52c68f0ca Print out immediate offset versions of PC-relative load/store instructions as [pc, #123] rather than simply #123.

Devang Patel 5e6b65cf0d Do not unnecessarily use AT_specification DIE because it does not add any value. 
Few weeks ago, llvm completely inverted the debug info graph. Earlier each debug info node used to keep track of its compile unit, now compile unit keeps track of important nodes. One impact of this change is that the global variable's do not have any context, which should be checked before deciding to use AT_specification DIE.

Nadav Rotem 253a7391ee add another testcase for pr10902 
llvm-svn: 140257
 2011-09-21 17:13:40 +00:00
Nadav Rotem bc9ba30158 [VECTOR-SELECT] Address one of the bugs in pr10902. 
Vector SetCC result types need to be type-legalized.
This code worked before because scalar result types are known to be legal.

Eric Christopher 155137bd10 Remove llvm-gcc and various compiler handling from llvm. It's not needed 
here anymore and has been migrated to the test-suite project.

Bill Wendling 36faa4d49c This test is completely invalid with the modern EH model. Delete.

Eli Friedman 1815b688cc Make sure IPSCCP never marks a tracked call as overdefined in SCCPSolver::ResolvedUndefsIn. If we do, we can end up in a situation where a function is resolved to return a constant, but the caller is marked overdefined, which confuses the code later.

subvector inserts and extracts. Initial patch by Rackover, Zvi with
some tweak done by me.

Bill Wendling cf1372d183 Update this test to the new EH model. 
Though I think it may be obsolete with the loop extract changes. And I couldn't
get the old version of LLVM to compile so that I could reduce this testcase.

declaration.

NAKAMURA Takumi 011be52871 test/CodeGen/X86/avx-minmax.ll: Unbreak Win32. 
On Windows x64, 128-bit arguments are not passed by reg but by indirect. eg.

maxpd:
        vmovapd (%rcx), %xmm0
        vmaxpd  (%rdx), %xmm0, %xmm0

FIXME: I don't care YMM on x64 for now.

Andrew Trick 8586e62d91 ARM isel bug fix for adds/subs operands. 
Modified ARMISelLowering::AdjustInstrPostInstrSelection to handle the
full gamut of CPSR defs/uses including instructins whose "optional"
cc_out operand is not really optional. This allowed removal of the
hasPostISelHook to simplify the .td files and make the implementation
more robust.
Fixes rdar://10137436: sqlite3 miscompile
