Raw Normal View History

Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

[PATCH] x86_64: make string func definition work as intended In include/asm-x86_64/string.h there are such comments: /* Use C out of line version for memcmp */ #define memcmp __builtin_memcmp int memcmp(const void * cs,const void * ct,size_t count); This would mean that if the compiler does not decide to use __builtin_memcmp, it emits a call to memcmp to be satisfied by the C out-of-line version in lib/string.c. What happens is that after preprocessing, in lib/string.i you may find the definition of "__builtin_strcmp". Actually, by accident, in the object you will find the definition of strcmp and such (maybe a trick intended to redirect calls to __builtin_memcmp to the default memcmp when the definition is not expanded); however, this particular case is not a documented feature as far as I can see. Also, the EXPORT_SYMBOL does not work, so it's duplicated in the arch. I simply added some #undef to lib/string.c and removed the (now duplicated) exports in x86-64 and UML/x86_64 subarchs (the second ones are introduced by another patch I just posted for -mm).
