| commit gcc-15-2986-gcd2f394418b | Author: Andrew Pinski quic_apinski@quicinc.com | Date: Sat Apr 20 00:13:12 2024 -0700 | | PHIOPT: move factor_out_conditional_operation over to use gimple_match_op | | To start working on more with expressions with more than one operand, converting | over to use gimple_match_op is needed. | The added side-effect here is factor_out_conditional_operation can now support | builtins/internal calls that has one operand without any extra code added. | | ... 20 lines of the commit log omitted.
