The proposal is as an ABI only (compilers would generate calls to __memcmpeq from boolean uses of memcmp, users wouldn't write calls to __memcmpeq directly, __memcmpeq wouldn't be declared in installed libc headers). If such dependence arises, that would suggest a compiler bug wrongly generating such calls for non-boolean memcmp uses. -- Joseph S. Myers jos...@codesourcery.com
