Re: [PATCH] valgrind: ignore SSE-based strlen invalid reads

Carlos Martín Nieto [off-list ref] writes:

 Looking at that header, strlen is one of the few functions not being
replaced by its __builtin version, and I only see __builtin_strlen in
the C++ patches. I'll rephrase to something like "Some versions of
strlen use SSE which then get inlined" to avoid blaming anyone in
particular, though thinking about it, it does seem logical that it's
GCC's builtin strlen.

All processor optimized versions of strlen in glibc are out-of-line, so
any use of SSE can only come from __builtin_strlen.
