Meador Inge 30d8f0e977 Normalize memcmp constant folding results. ... The library call simplifier folds memcmp calls with all constant arguments to a constant. For example: memcmp("foo", "foo", 3) -> 0 memcmp("hel", "foo", 3) -> 1 memcmp("foo", "hel", 3) -> -1 The folding is implemented in terms of the system memcmp that LLVM gets linked with. It currently just blindly uses the value returned from the system memcmp as the folded constant. This patch normalizes the values returned from the system memcmp to (-1, 0, 1) so that we get consistent results across multiple platforms. The test cases were adjusted accordingly. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@167726 91177308-0d34-0410-b5e6-96231b3b80d8		2012-11-12 14:00:45 +00:00
