Detailed Description
InstructionData. Contains information about insn pattern.
Field Documentation
If insn is a SET, this is its left hand side.
| regset idata_def::reg_clobbers |
Registers that are set/used by this insn. This info is now gathered
via sched-deps.c. The downside of this is that we also use live info
from flow that is accumulated in the basic blocks. These two infos
can be slightly inconsistent, hence in the beginning we make a pass
through CFG and calculating the conservative solution for the info in
basic blocks. When this scheduler will be switched to use dataflow,
this can be unified as df gives us both per basic block and per
instruction info. Actually, we don't do that pass and just hope
for the best.
If insn is a SET, this is its right hand side.
Type of the insn.
o CALL_INSN - Call insn
o JUMP_INSN - Jump insn
o INSN - INSN that cannot be cloned
o USE - INSN that can be cloned
o SET - INSN that can be cloned and separable into lhs and rhs
o PC - simplejump. Insns that simply redirect control flow should not
have any dependencies. Sched-deps.c, though, might consider them as
producers or consumers of certain registers. To avoid that we handle
dependency for simple jumps ourselves.
