[PATCH] Change EQ_ATTR_ALT to support up to 64 alternatives

2018-09-19 Thread Ilya Leoshkevich
On S/390 there is a need to support more than 32 instruction alternatives per define_insn. Currently this is not explicitly prohibited or unsupported: MAX_RECOG_ALTERNATIVES is equal 35, and, futhermore, the related code uses uint64_t for bitmaps in most places. However, genattrtab contains the l
