When I try:
gcc -m64 -O1 -mcpu=ultrasparc -fcall-used-g4 -fcall-used-g5 -fcall-used-g6 -fc
all-used-g7 -c -I. -D___PRIMAL -D___LIBRARY -D___SINGLE_HOST main.c;
with
banach-51% gcc -v
Reading specs from /pkgs/gcc-2.96/lib/gcc-lib/sparc-sun-solaris2.8/3.1/specs
Configured with: ../configure --prefix=/pkgs/gcc-2.96 --enable-checking=no
gcc version 3.1 20010403 (experimental)
I get
cc1: -m64 is not supported by this configuration
I want to test 64bit code generation for the new subreg-byte stuff;
how do I configure gcc to do this?
BTW, several people have reported porting this to the 3.0 prerelease
branch without any problems; it would be really cool if 64 bit
code generation worked on ultrasparc in 3.0.
