2008-12-19Move the patterns which have i8 immediates before the patternsDan Gohman
that have i32 immediates so that they get selected first. This currently only matters in the JIT, as assemblers will automatically use the smallest encoding. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@61250 91177308-0d34-0410-b5e6-96231b3b80d8

2008-12-19Resubmit support for the 'nocapture' attribute.Nick Lewycky
The problematic part of this patch is that we were out of attribute bits, requiring some fancy bit hacking to make it fit (by shrinking alignment) without breaking existing users or the file format. This change will require users to rebuild llvm-gcc to match llvm. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@61239 91177308-0d34-0410-b5e6-96231b3b80d8

2008-12-18Mark the x86 fp stack registers as "reserved". This tells LiveVariablesDan Gohman
and the RegisterScavenger not to expect traditional liveness techniques are applicable to these registers, since we don't fully modify the effects of push and pop after stackification. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@61179 91177308-0d34-0410-b5e6-96231b3b80d8
2008-12-18Fix the time regression I introduced in 464.h264ref withDale Johannesen
my last patch to this file. The issue there was that all uses of an IV inside a loop are actually references to Base[IV*2], and there was one use outside that was the same but LSR didn't see the base or the scaling because it didn't recurse into uses outside the loop; thus, it used base+IV*scale mode inside the loop instead of pulling base out of the loop. This was extra bad because register pressure later forced both base and IV into memory. Doing that recursion, at least enough to figure out addressing modes, is a good idea in general; the change in AddUsersIfInteresting does this. However, there were side effects.... It is also possible for recursing outside the loop to introduce another IV where there was only 1 before (if the refs inside are not scaled and the ref outside is). I don't think this is a common case, but it's in the testsuite. It is right to be very aggressive about getting rid of such introduced IVs (CheckForIVReuse and the handling of nonzero RewriteFactor in StrengthReduceStridedIVUsers). In the testcase in question the new IV produced this way has both a nonconstant stride and a nonzero base, neither of which was handled before. (This patch does not handle all the cases where this can happen.) And when inserting new code that feeds into a PHI, it's right to put such code at the original location rather than in the PHI's immediate predecessor(s) when the original location is outside the loop (a case that couldn't happen before) (RewriteInstructionToUseNewBase); better to avoid making multiple copies of it in this case. Everything above is exercised in CodeGen/X86/lsr-negative-stride.ll (and ifcvt4 in ARM which is the same IR). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@61178 91177308-0d34-0410-b5e6-96231b3b80d8

2008-12-17Today the front-ends (llvm-gcc and clang) generate multiple ↵Devang Patel
llvm.dbg.compile_units to identify source file for various debug entities. Each llvm.dbg.compile_unit matches one file on the disk. However, the backend only supports one DW_TAG_compile_unit per .o file. The backend selects first compile_unit from the vector to construct DW_TAG_compile_unit entry, which is not correct in all cases. First step to resolve this is, record file name and directory directly in debug info for various debug entities. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@61164 91177308-0d34-0410-b5e6-96231b3b80d8
