During the bootstrap, the GCC build fails at gcc/attribs.c with this error:
attribs.s:514: Error: can't resolve `.text.unlikely' {.text.unlikely section} -
`.LFB96' {.text section}
Line 514 in the .s file is:
.long .LFE96-.LFB96
One label is in a .text section and the other label is in a .text.unlikely
section. I tried placing the .text.unlikely label into .text and it assembled
correctly.
The failed command is:

This is in the last bit of the build, using profile feedback to optimize.
