Between 20161202 and 20161205, a couple of testcases started to FAIL on
32-bit Solaris/x86:
+FAIL: gcc.target/i386/pr70322-1.c scan-assembler pandn
+FAIL: gcc.target/i386/pr70322-2.c scan-assembler pandn
+FAIL: gcc.target/i386/pr70322-3.c scan-assembler por
+FAIL: gcc.target/i386/pr70322-3.c scan-assembler pxor
+FAIL: gcc.target/i386/pr70322-4.c scan-assembler por
+FAIL: gcc.target/i386/pr70322-4.c scan-assembler psub
This is the same issue as PR target/77483, as is the solution.
The following patch implements it. Bootstrapped without regressions on
i386-pc-solaris2.12 and x86_64-pc-linux-gnu (both 32 and 64-bit
multilibs). Ok for mainline?
