Recent versions of binutils (with commit b25f942e18d6ecd7ec3e2d2e9930eb4f996c258a) stopped preserving "sticky" options across a base `.machine` directive, nullifying the use of passing "-many" through GCC to the assembler. As a result, some instructions which were recognized even under older, more stringent `.machine` directives become unrecognized instructions in that context. In `sysdeps/powerpc/tst-set_ppr.c`, the use of the `mfppr32` extended mnemonic became unrecognized, as the default compilation with GCC for 32bit powerpc adds a `.machine ppc` in the resulting assembly, so the command line option `-Wa,-many` is essentially ignored, and the ISA 2.06 instructions and mnemonics, like `mfppr32`, are unrecognized. The compilation of `sysdeps/powerpc/tst-set_ppr.c` fails with: Error: unrecognized opcode: `mfppr32' Add appropriate `.machine` directives in the assembly to bracket the `mfppr32` instruction.
