- Subject: Gcc builtin functions used by glibc not available on mips
In glibc, there are codes
/* Partly clean the `bootstrap_map' structure up. Don't use
`memset' since it might not be built in or inlined and we cannot
make function calls at this point. Use '__builtin_memset' if we
know it is available. */
#if __GNUC_PREREQ (2, 96)
__builtin_memset (bootstrap_map.l_info, '\0', sizeof (bootstrap_map.l_info));
#else
for (cnt = 0;
cnt < sizeof (bootstrap_map.l_info) / sizeof (bootstrap_map.l_info[0]);
++cnt)
bootstrap_map.l_info[cnt] = 0;
#endif
used in ld.so bootstrap. The problem is even gcc 3.1 doesn't have a
real __builtin_memset for mips. I am very reluctant to call it a gcc
bug. Maybe we should check it during the gcc configure instead of
depending on "#if __GNUC_PREREQ (2, 96)".
