  Subject: RFA: Testsuite fixes (3/3): USER_LABEL_PREFIX
       To: gcc-patches@gcc.gnu.org

We have some new tests that use assembler names without regard to
USER_LABEL_PREFIX.  These tests fail for targets with non-empty
USER_LABEL_PREFIX during the assembly phase.

Fixed by using ASMNAME macro like in e.g. gcc.dg/alias-7.c .

Regression tested with x86_64-unknown-linux-gnu X sh-elf .
This fixes 15 spurious FAILures, giving 27 more expected PASSes.

OK in the absence of testsuite maintainer objections within 48 hours.
