- /* we need to do this because gas is really a bsd style assembler,
- * and so doesn't work well this these att-isms:
- *
- * ASM_OUTPUT_SKIP is .set .,.+N, which isn't implemented in gas
- * ASM_OUTPUT_LOCAL is done with .set .,.+N, but that can't be
- * used to define bss static space
- *
- * Next is the question of whether to uses underscores. RMS didn't
- * like this idea at first, but since it is now obvious that we
- * need this separate tm file for use with gas, at least to get
- * dbx debugging info, I think we should also switch to underscores.
- * We can keep tm-i386v for real att style output, and the few
- * people who want both form will have to compile twice.
