Hi,
I do not like the idea of adding
amd64_set_gsbase and i386_set_fsbase into our shared libc.
The only user so far is wine,
it already have OS specific setting of fs/gs.
#if defined __linux__
arch_prctl( ARCH_SET_GS, teb );
#elif defined (__FreeBSD__) || defined (__FreeBSD_kernel__)
amd64_set_gsbase( teb );
#else
# error Please define setting %gs for your architecture
#endif
The best way should be to alter wine to use sysarch directly,
just "sysarch (AMD64_SET_GSBASE, &teb)"
instead of "amd64_set_gsbase( teb )"
The second option is to insert into
<machine/sysarch.h> "always inline" functions.
