With tilepro removal, the uppercase instruction are not anymore required to be defines as potentially macros. This is a mechanical change done by the following shell script: --- INSNS="LD LD4U ST ST4 BNEZ BEQZ BEQZT BGTZ CMPEQI CMPEQ CMOVEQZ CMOVNEZ" FILES=$(find sysdeps/tile sysdeps/unix/sysv/linux/tile -iname *.S) for insn in $INSNS; do repl=$(echo $insn | tr '[:upper:]' '[:lower:]') sed -i 's/\b'$insn'\b/'$repl'/g' $FILES done --- Checked with a build for tilegx-linux-gnu and tilegx-linux-gnu-32 with and without the patch, there is no difference in generated binary with a dissassemble. * sysdeps/tile/__longjmp.S (__longjmp): Use lowercase instructions. * sysdeps/tile/__tls_get_addr.S (__tls_get_addr): Likewise. * sysdeps/tile/_mcount.S (__mcount): Likewise. * sysdeps/tile/crti.S (_init, _fini): Likewise. * sysdeps/tile/crtn.S: Likewise. * sysdeps/tile/dl-start.S (_start): Likewise. * sysdeps/tile/dl-trampoline.S: Likewise. * sysdeps/tile/setjmp.S (__sigsetjmp): Likewise. * sysdeps/tile/start.S (_start): Likewise. * sysdeps/unix/sysv/linux/tile/clone.S (_clone): Likewise. * sysdeps/unix/sysv/linux/tile/getcontext.S (__getcontext): Likewise. * sysdeps/unix/sysv/linux/tile/ioctl.S (__ioctl): Likewise. * sysdeps/unix/sysv/linux/tile/setcontext.S (__setcontext): Likewise. * sysdeps/unix/sysv/linux/tile/swapcontext.S (__swapcontext): Likewise. * sysdeps/unix/sysv/linux/tile/syscall.S (syscall): Likewise. * sysdeps/unix/sysv/linux/tile/vfork.S (__vfork): Likewise.
