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
FAIL: g++.dg/debug/dwarf2/pr54508.C -std=gnu++98  scan-assembler "s\\\\\\\\0"[ \\t]+[#;/!|@]+ DW_AT_name
FAIL: g++.dg/debug/dwarf2/pr54508.C -std=gnu++98  scan-assembler "f1\\\\\\\\0"[ \\t]+[#;/!|@]+ DW_AT_name
FAIL: g++.dg/debug/dwarf2/pr54508.C -std=gnu++98  scan-assembler "u\\\\\\\\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.
