Power/GAS: Don't set VLE annotation for non-VLE processors/instructions
Only set the VLE flag if the instruction has been pulled via the VLE
instruction set. This way the flag is guaranteed to be set for VLE-only
instructions or for VLE-only processors, however it'll remain clear for
dual-mode instructions on dual-mode and, more importantly, standard-mode
processors.
gas/
* config/tc-ppc.c (md_assemble): Only set the PPC_APUINFO_VLE
flag if both the processor and opcode flags match.
ld/testsuite/
* ld-powerpc/apuinfo-vle.rd: New test.
* ld-powerpc/apuinfo-vle.s: New test source.
* ld-powerpc/apuinfo.rd: Adjust according to GAS PPC_APUINFO_VLE
handling change.
* ld-powerpc/powerpc.exp: Run the new test.
