Summary: cross-check DW_AT_name vs. demangling of linkage names
Product: gcc
Version: 4.7.0
Status: UNCONFIRMED
Severity: enhancement
Priority: P3
Component: debug
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: jan.kratoch...@redhat.com
CC: do...@gcc.gnu.org
PR debug/49408 shows DW_AT_name "K<&S::m>" vs. demangled
DW_AT_MIPS_linkage_name prefix "K<&(S::m(int))>". This was due to a bug in
libiberty/cp-demangle.c.

Therefore I believe there could be compile time sanity cross-check with ICE in
such cases, maybe more such bugs exist there already.
