The recent IPA-SRA patch completely broke LTO on Solaris/x86 with the
native assembler:
FAIL: gcc.c-torture/compile/20000105-1.c -O2 -flto -flto-partition=none
(test for excess errors)
Excess errors:
Assembler: 20000105-1.c
"/var/tmp//ccaW7VHa.s", line 35 : Syntax error
Near line: " .section
.gnu.lto_.ipa-sra.e03463101918c5a8,#exclude"
This happens because tokens (including section names) can only consist
of letters, digits, '_' and '.'.
Fixed by using '_' instead of '-' as all other LTO section names do.
Tested on i386-pc-solaris2.11 and i686-pc-linux-gnu, installed on
mainline as pre-approved by Richard in the PR.
