[llvm-commits] [patch] Implement no-canonical-prefixes.

[Rafael Espindola]

Gcc's option -fno-canonical-prefixes is useful for the case where gcc
and cc1 are symbolic links to different directories. The same is true
for clang and clang-cc. For example, if  we have

bin/clang -> /foo/clang
bin/clang-cc /bar/clang-cc

clang will fail to find clang-cc since it will look for /foo/clang-cc.

The attached patch implements -no-canonical-prefixes in the driver.

For more information see.
