This patch fixes PR rtl-optimization/60155.
The PA backend has a number of INSN patterns which trap on signed
overflow. These are
implemented as parallels using the trap_if code. Currently, single_set
does not consider
a parallel with a trap_if rtx to be a single set. This causes an ICE in
gcse.c when an insn with
a trap_if is encountered.
The problem is fixed by implementing a gcse specific version of
"single_set" which only
looks at whether there is a single non-dead set in an insn pattern. It
allows multiple other
sets if they are dead.
Tested on hppa-unknown-linux-gnu, hppa2.0w-hp-hpux11.11 and
hppa64-hp-hpux11.11.
OK for trunk?
Yes. This is good. Thanks.
Attached is an update to the previous change. I was going to send it
this evening.
It adds an assert to check whether insn is actually an INSN and it
optimizes the
common case as in the single_set macro.
Tested on same targets as above.
Is update OK? Otherwise, I will apply first version.
Yea, the update is fine. THanks.
Sorry again for the delay.
