This info is from assembler (as):
$ as --target-help
-Q ignored
-V print assembler version number
-k ignored
-n Do not optimize code alignment
-q quieten some warnings
-s ignored
--32/--64 generate 32bit/64bit code
--divide ignored
-march=CPU/-mtune=CPU generate code/optimize for CPU, where CPU is one of:
i386, i486, pentium, pentiumpro, pentium4, nocona,
core, core2, k6, athlon, k8, generic32, generic64
It would be nice, if assembler displayed something like linker does:
Linker options
==============
Use "-Wl,OPTION" to pass "OPTION" to the linker.
