[Bug bootstrap/43299] New: Subversion id 157264 breaks powerpc 64-bit bootstraps

[meissner at gcc dot gnu dot org]

Unless you use BOOT_CFLAGS='-g -O2 -fno-var-tracking', the change Jakub made on
March 7th, 2010 breaks the powerpc 64-bit bootstrap.

Here is the error message:
/tmp/cckGWIfy.s: Assembler messages:
/tmp/cckGWIfy.s:117666: Error: junk at end of line, first unrecognized
character is `@'
/tmp/cckGWIfy.s:117685: Error: junk at end of line, first unrecognized

The problem is inside of the dwarf debugging output, is:

The .8byte directive is not expecting a TOC reference.  Here is the definition
of .LC355:
        .section        ".toc","aw"
.LC354:
        .tc gen_load_locked_si[TC],gen_load_locked_si
.LC355:
        .tc gen_load_locked_di[TC],gen_load_locked_di
