Hi-
Here's a brief update on my previous email.
I've built and installed EGCS-971008 with the following flags:
--enable-haifa=yes --with-gnu-as --with-gnu-ld --with-stabs
on a Model 170 UltraSPARC running Solaris 2.5
I compiled a program with the following flags:
-mcpu=ultrasparc -funsigned-char -fno-exceptions -O6
-finline-functions -ffast-math -fomit-frame-pointer
-funroll-loops
The speed of the program (which does a lot of floating point) was
about the same as when I compiling it with FSF-GCC-2.7.2 and these
flags:
-O3 -finline-functions -ffast-math -fomit-frame-pointer
-funroll-loops
I haven't re-run this test with the SUNW cc yet. I don't know if this
gives anyone any useful information, but I thought I'd provide it
nonetheless.
