i386.md (shift patterns): Use (TARGET_SHIFT1 || optimize_size) to decide whether emit the short opcode.
* i386.md (shift patterns): Use (TARGET_SHIFT1 || optimize_size) to
decide whether emit the short opcode.
* i386.h (x86_shift1): Declare.
(TARGET_SHIFT1): New macro.
* i386.c (x86_shift1): New global variable.
* toplev.c (rest_of_compilation): Call find_basic_block pre-loop unconditionally;
make loop to rebuild CFG; kill unnecesary find_basic_block calls;
kill compute_bb_for_insn call.
* cfgbuild.c (find_basic_blocks): Kill compute_bb_for_insn call.
* haifa-sched.c (sched_init): Likewise.
