2009-03-13Temporarily XFAIL this test.Bill Wendling
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@66866 91177308-0d34-0410-b5e6-96231b3b80d8
2009-02-15Update the list of function annotations for nocapture. All of these came upNick Lewycky
when I was looking at functions used by python. Highlights include, better largefile support (64-bit file sizes on 32-bit systems), fputs string is nocapture, popen/pclose added (popen being noalias return), modf and frexp and friends. Also added some missing 'break' statements and combined identical sections. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@64615 91177308-0d34-0410-b5e6-96231b3b80d8
2009-02-13Mark strto* as readonly when the endptr is null.Nick Lewycky

2009-02-13On strtod and friends, mark 'endptr' nocapture in the function prototype, andNick Lewycky
mark the first argument nocapture if endptr=NULL for each particular call. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@64453 91177308-0d34-0410-b5e6-96231b3b80d8
2009-02-12Don't mark all args to strtod and friends as nocapture.Nick Lewycky
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@64352 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-18Fix copy and pasted typos that prevented strtok_r, realloc, getenv, ungetc,Nick Lewycky
putc, puts, perror, vscanf and vsscanf from getting annotations. Add annotations for eight printf functions, memalign, pread and pwrite. On Linux, llvm-gcc sometimes renames strdup, getc, putc, strtok_r, scanf and sscanf. Match the alternate function names. Fix a crash annotating opendir. Don't mark fsetpos's second parameter as nocapture. It's supposed to be captured. Do mark fopen's path and mode strings as nocapture. Mark ferror as readonly, but not fileno which may set errno. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@62456 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-05Move the libcall annotating part from doFinalization to doInitialization.Nick Lewycky
Finalization occurs after all the FunctionPasses in the group have run, which is clearly not what we want. This also means that we have to make sure that we apply the right param attributes when creating a new function. Also, add a missed optimization: strdup and strndup. NoCapture and NoAlias return! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@61658 91177308-0d34-0410-b5e6-96231b3b80d8

2008-12-21Turn strcmp into memcmp, such as strcmp(P, "x") --> memcmp(P, "x", 2).Nick Lewycky

2008-11-30Optimize memmove and memset into the LLVM builtins. Note that these Eli Friedman
only show up in code from front-ends besides llvm-gcc, like clang. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@60287 91177308-0d34-0410-b5e6-96231b3b80d8

2008-06-30- Re-apply 52748 and friends with fix. GetConstantStringInfo() returns an ↵Evan Cheng
empty string for ConstantAggregateZero case which surprises selectiondag. - Correctly handle memcpy from constant string which is zero-initialized. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@52891 91177308-0d34-0410-b5e6-96231b3b80d8
2008-06-29Revert (52748 and friends):Anton Korobeynikov
Move GetConstantStringInfo to lib/Analysis. Remove string output routine from Constant. Update all callers. Change debug intrinsic api slightly to accomodate move of routine, these now return values instead of strings. This unbreaks llvm-gcc bootstrap. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@52884 91177308-0d34-0410-b5e6-96231b3b80d8
