Vladimir,
This patch fixes a problem (found on s390) in one of the committed
fuse-caller-save patches. s390 is the only user of the
IRA_HARD_REGNO_ADD_COST_MULTIPLIER target macro. The problem in the
fuse-caller-save patch is that the code guarded by
IRA_HARD_REGNO_ADD_COST_MULTIPLIER in ira_tune_allocno_costs is not
call-related, but is now conditional on a ALLOCNO_CROSSED_CALLS_CLOBBERED_REGS
test. This patch fixes that.
Bootstrapped and reg-tested on x86_64. No issues found ( other than a
non-reproducible failure while testing the non-bootstrap version:
https://gcc.gnu.org/ml/gcc/2014-09/msg00065.html ).
OK for trunk ?
Thanks,
- Tom
