I'd like to choose cpu specific CFLAGS, for Athlon,pentium 3,4,5,6,7...
and AC_CANONICAL_TARGET seems to return only canonical names like cpu and i'd l
I think, i'm still a newbye, the right approach would be something like:
AC_CANONICAL_BUILD
AC_CANONICAL_HOST
AC_PROG_CC
#pseudo code, i haven't still wrote anything in M4
"if CC==gcc then
if build_cpu == host_cpu then
check -x /proc/cpuinfo
//mySmartParseFunction TODO :D :(
//this powerful function can choose best flags for pentium 1,2,3,4,
athlon and friends
CFLAGS=mySmartParseFunction(/proc/cpuinfo)
"
ok it is very very bad code,
but my question is "idea is bad too?"
Thanks
