Plans for Linux ELF i686+ ABI ? Like SPARC V8+ ?

2007-10-14 Thread Darryl L. Miles
Hello, On SPARC there is an ABI that is V8+ which allows the linking (and mixing) of V8 ABI but makes uses of features of 64bit UltraSparc CPUs (that were not available in the older 32bit only CPUs). Admittedly looking at the way this works it could be said that Sun had a certain about of

GNU/Linux ABI documentation ? GCC supports SSSE3 in general purpose code generation ?

Is there a document or standard (or group of standards) that define the collective ABIs of GNU/Linux systems using ELF binary formats of various CPU architectures, including at least: IA32 (i386/i686/AMD64/EMT64/etc...) ARM (v5, v5t, v7, etc...) What is the policy of the GNU toolchain,
