State-Changed-By: rodrigc
State-Changed-When: Mon Aug 13 16:33:30 2001
State-Changed-Why:
I cannot compile this test case with IA32 version of:
gcc version 3.0.1 20010813 (prerelease)
x.i: In function `__brk':
x.i:9: invalid register name `%d0' for register variable
x.i:10: unknown register name `%d1' in `asm'
x.i:10: unknown register name `%d0' in `asm'
x.i:10: invalid `asm': invalid %%-code
Is this still a problem?
