gcc bootstrap problem on Linux/68060

[Joerg Dorchain <dorchain at wirbel dot com>]

Hi,

I have problems building egc from source on my Linux/m68k system. It has
a 68060 CPU, egcs version is 1.1.2. The compiler used for bootstrapping
is a gcc-2.7.2.3 with a 68060 patch.
The problem is that I get a "fixed or forbidden register spilled" when
doing a make bootstrap when compiling libgcc2.c
At this point, the newly built gcc is used, so I do not assume it to be
gcc-2.7 fault.

I found a workaround (attached) on a mailing list, but would be pleased to see it
fixed in egcs itself.

If you need further Information please get back to me.

Bye,

Joerg

Just for clarification, this is the Stefanīs patch we are using to build gcc
and egcs on 060 machines:

--- gcc/Makefile.in.orig        Tue Oct 13 20:59:05 1998
+++ gcc/Makefile.in     Tue Oct 13 20:59:15 1998

 # TCFLAGS is used for compilations with the GCC just built.
 XCFLAGS =
 TCFLAGS =
-CFLAGS = -g
+CFLAGS = -g -O
 BOOT_CFLAGS = -O2 $(CFLAGS)
 WARN_CFLAGS = 
 # These exists to be overridden by the x-* and t-* files, respectively.

It is switching _on_ optimization. Is it for the first stage compiler or for
more?

Ciao,
Christian.
