The check-in lacked the gcc/testsuite ChangeLog. Besides, the patch
caused a testsuite regression on Solaris with /bin/as (sparc and x86, 32
and 64-bit):
+FAIL: g++.dg/debug/dwarf2/typedef1.C -std=gnu++11 scan-assembler-times DW_AT_name: "foo<1>"|"foo<1u>.."[^\\n]*DW_AT_name 1
+FAIL: g++.dg/debug/dwarf2/typedef1.C -std=gnu++14 scan-assembler-times DW_AT_name: "foo<1>"|"foo<1u>.."[^\\n]*DW_AT_name 1
+FAIL: g++.dg/debug/dwarf2/typedef1.C -std=gnu++98 scan-assembler-times DW_AT_name: "foo<1>"|"foo<1u>.."[^\\n]*DW_AT_name 1
Turns out an incomplete adjustment to the pattern, fixed as follows.
Will commit as obvious once testing on more configurations (gas, Linux)
has completed.
