Hello,
Linux support for i386 has been removed. Should we do the same for GCC?
The "oldest" ix86 variant that'd be supported would be i486.
The benefit would be a few good cleanups:
* PROCESSOR_I386 / TARGET_386 can be removed
* X86_TUNE_DOUBLE_WITH_ADD can be removed (always true)
* X86_ARCH_CMPXCHG/X86_ARCH_XADD/X86_ARCH_BSWAP can be removed.
* The only ix86 variant without lock-free atomic int support goes
away, which probably allows for a few more cleanups in some of the
libraries (?).
Not much, but something is more than nothing :-)
Ciao!
Steven
