g++.dg/debug/dwarf2/pr54508.C is FAILing on Solaris 9/x86 (both with as
and gas):
FAIL: g++.dg/debug/dwarf2/pr54508.C -std=gnu++98 scan-assembler "c\\\\\\\\0"[
\\t]+[#;/!|@]+
DW_AT_name[\\r\\n]+[^\\r\\n]+[\\r\\n]+[^\\r\\n]+[\\r\\n]+[^#;/!|@]+[#;/!|@]+

DW_AT_decl_line[\\r\\n]+[^#;/!|@]+[#;/!|@]+ DW_AT_declaration
This turns out to be due to whitespace differences in assembler
comments between Solaris 9 and 10:
- .byte 0x3 / uleb128 0x3; (DW_AT_name)
+ .byte 0x3 / uleb128 0x3; (DW_AT_name)
I've traced this to different values of ASM_COMMENT_START:
config/i386/unix.h:#define ASM_COMMENT_START "/ "
config/i386/sol2-bi.h:#define ASM_COMMENT_START "/"
The following patch fixes this; tested with the appropriate runtest
invocations on i386-pc-solaris2.9, i386-pc-solaris2.10, and
x86_64-unknown-linux-gnu.
Ok for mainline?

* g++.dg/debug/dwarf2/pr54508.C: Allow for more whitespace after
asm comments.
