[llvm-commits] [PATCH v2 0/2] instcombine: wire up -fno-builtin to the library call simplifier

[Meador Inge]

As discussed here [1] the correct way to wire up -fno-builtin to the
instcombine library call simplifiers is to take advantage of the target
library information.  This patch set adds a few missing functions to the
TLI and adds the appropriate queries to the simplifier framework.  I have
also added new tests to tools/clang/test/CodeGen/libcalls-fno-builtin.c
for verifying the -fno-builtin behavior, but I will submit that patch to
cfe-commits.

OK?
