ipa: Avoid looking for IPA-SRA replacements where there are none
While modifying the code, I realized that we do look into statements
even when there are no replacements. This patch adds the necessary
early bail-outs to avoid that.
ipa_param_body_adjustments::modify_call_stmt cannot have the same at
the very beginning because calls can still contain otherwise removed
parameters that need to be removed from the statements too.
gcc/ChangeLog:
2022-11-11 Martin Jambor <mjambor@suse.cz>
* ipa-param-manipulation.cc
(ipa_param_body_adjustments::modify_expression): Bail out early if
there are no replacements.
(ipa_param_body_adjustments::modify_assignment): Likewise.
