-march=pentiumpro and BOOT_CFLAGS

-march=pentiumpro and BOOT_CFLAGS

[acs]

On my UnixWare 2.1.2 system, if I include -march=pentiumpro in
BOOT_CFLAGS, I cannot bootstrap the 1225 snapshot.
After building the stage1 compiler, here's the error I get:

stor-layout.s:439: Error: invalid character '$' in opcode
stor-layout.s:440: Error: invalid character '$' in opcode

Here are the offending lines from stor-layout.s:

438  .L168:
439      mov$8 -40(%ebp),%edx
440      mov$8 %edx,-4(%ebp)

(This is with binutils.2.0.1.18, in case that matters.)

Without -march=pentiumpro, the snapshot bootstraps and compares fine.
BTW, I built egcs-1.0 with no difficulty using -march=pentiumpro.

Not needed.  The real problem was in jump.c

What happened to this patch?

Thu Nov 20 10:05:00 1997  Stan Cox (scox@cygnus.com)
 
        * i386.md: (movsicc, movhicc): Replace m=cc0?g:g alternative by
        m=cc0?ri:ri and r=cc0?g:g, which eliminates the need for a
        scratch register.
        (movsfcc, movdfcc, movxfcc): Use register_operand for op0 and
        nonimmediate_operand for op2 and op3.

I thought it would be installed after egcs 1.0.

Thanks.

Thanks.  Installed.

The opcode suffix was being pulled from the wrong operand.

        * i386.md: (movsicc_1, movhicc_1):  For alternate 3 set the opcode
        suffix from operand 3.
