[Bug target/44494] New: [4.6 regression] Several SPARC testcases fail

[ro at gcc dot gnu dot org]

Since a few days, a couple of __sync_fetch_and_* testcases fail on Solaris
2/SPARC
(Solaris 8 to 10), both 32 and 64-bit, Sun as and gas:

+FAIL: gcc.c-torture/compile/sync-3.c  -O2  (test for excess errors)
+FAIL: gcc.c-torture/compile/sync-3.c  -O3 -fomit-frame-pointer  (test for
exces
s errors)
+FAIL: gcc.c-torture/compile/sync-3.c  -O3 -g  (test for excess errors)
+FAIL: gcc.c-torture/compile/sync-3.c  -O2 -flto  (test for excess errors)
+FAIL: gcc.c-torture/compile/sync-3.c  -O2 -fwhopr  (test for excess errors)

libgomp is equally affected.

The offending code looks like this:

FAIL: gcc.c-torture/compile/sync-3.c  -O2  (test for excess errors)
Excess errors:
/usr/ccs/bin/as: "/var/tmp//ccwUTreE.s", line 158: error: statement syntax

        cas     [%fp-28], %g1, %g3
