Clarke" Cc: tuliom@linux.vnet.ibm.com Errors-To: libc-alpha-bounces+patchwork=sourceware.org@sourceware.org Sender: "Libc-alpha" Recent versions of GCC stopped passing "-many" to the assembler, so some instructions which were under older, more stringent "machine" directives no longer compile with unrecognized instructions in that context. In tst-ucontext-ppc64-vscr.c, while the instructions provoking the new error messages are bracketed by ".machine power5", which is ostensibly Power ISA 2.03 (POWER5), the POWER5 processor did not support the VSX subset, so these instructions are not recognized as "power5". Error: unrecognized opcode: `vspltisb' Error: unrecognized opcode: `vpkuwus' Error: unrecognized opcode: `mfvscr' Error: unrecognized opcode: `stvx' Manually adding the VSX subset via ".machine altivec" is sufficient.
