Subject: [Linux-ia64] IA-64 compile flags for gcc
Date: Wed, 20 Jun 2001 17:28:59 +0000 [thread overview]
Message-ID: <marc-linux-ia64-105590693005745@msgid-missing> (raw)
Many times when using gcc, I use certain flags to optimize the compilation,
for example with Solaris8 and a sparc IIe v9 cpu, I would use something
like...
CC=gcc CFLAGS="-O4 -mcpu=v8"; export CC CFLAGS
There are others as well. Also many times when doing a configure there is
an
option for something like --prefix=/foo/bar --hosth6 to optimize the code
for
my specific hardware.
Does anyone know what the "optimal" flags are for an IA-64 in gcc? I
realize you
can't always use the ones you want, but if you could...?
I have gone through a lot of the gcc documentation, but there is so much,
and
what I have seen so far doesn't cover this. Can anyone point me in the
right
direction?
Ray
