2012-02-16Replace all instances of dg.exp file with lit.local.cfg, since all tests are ↵Eli Bendersky
run with LIT now and now Dejagnu. dg.exp is no longer needed. Patch reviewed by Daniel Dunbar. It will be followed by additional cleanup patches. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@150664 91177308-0d34-0410-b5e6-96231b3b80d8

2011-11-17Add support for custom names for library functions in TargetLibraryInfo. ↵Eli Friedman
Add a custom name for fwrite and fputs on x86-32 OSX. Make SimplifyLibCalls honor the custom names for fwrite and fputs. Fixes <rdar://problem/9815881>. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@144876 91177308-0d34-0410-b5e6-96231b3b80d8

2011-10-05PR11061: Make simplifylibcalls fold strcmp("", x) correctly.Eli Friedman
While I'm here, fix the related issue with strncmp, add some actual tests for strcmp and strncmp, and start using StringRef::compare for constant folding instead of using strcmp/strncmp so that the optimized IR isn't dependent on the host's implementation of strcmp. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@141227 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-27Stop emitting instructions with the name "tmp" they eat up memory and have ↵Benjamin Kramer
to be uniqued, without any benefit. If someone prefers %tmp42 to %42, run instnamer. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@140634 91177308-0d34-0410-b5e6-96231b3b80d8
2011-08-12Move "atomic" and "volatile" designations on instructions after the opcodeEli Friedman
of the instruction. Note that this change affects the existing non-atomic load and store instructions; the parser now accepts both forms, and the change is noted in the release notes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@137527 91177308-0d34-0410-b5e6-96231b3b80d8
2011-06-18rip out a ton of intrinsic modernization logic from AutoUpgrade.cpp, which isChris Lattner
for pre-2.9 bitcode files. We keep x86 unaligned loads, movnt, crc32, and the target indep prefetch change. As usual, updating the testsuite is a PITA. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@133337 91177308-0d34-0410-b5e6-96231b3b80d8

2010-12-17Revert r64460. strtol and friends cannot be marked readonly, even withDan Gohman
a null endptr argument, because they may write to errno. This fixes a seflhost miscompile observed on Linux targets when TBAA was enabled. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@122014 91177308-0d34-0410-b5e6-96231b3b80d8

The memcmp will be optimized further and even the pathological case 'strstr(x, "x") == x' generates optimal code now. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@106097 91177308-0d34-0410-b5e6-96231b3b80d8

out the remainder of the calls that we should lower in some way and move the tests to the new correct directory. Fix up tests that are now optimized more than they were before by -instcombine. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@97875 91177308-0d34-0410-b5e6-96231b3b80d8

2009-12-24move an optimization for memcmp out of simplifylibcalls and into Chris Lattner
SDISel. This optimization was causing simplifylibcalls to introduce type-unsafe nastiness. This is the first step, I'll be expanding the memcmp optimizations shortly, covering things that we really really wouldn't want simplifylibcalls to do. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@92098 91177308-0d34-0410-b5e6-96231b3b80d8
