commit r16-5702-g36053843658f349bf645484b9dacd6f41a156d5e Author: Jakub Jelinek <[email protected]> Date: Fri Nov 28 22:05:34 2025 +0100 powerpc: PowerPC backend, meet C++20 C++20, in particular https://wg21.link/P1120R0 paper voted into it, deprecates various operations between enumerators from different enumeration types etc., and as we've switched to -std=gnu++20 by default, this now results in warnings or errors during stage2 and onwards. The following patch should fix rs6000 build. 2025-11-28 Jakub Jelinek <[email protected]> * config/rs6000/rs6000.cc (complex_multiply_builtin_code): Avoid arithmetics between enumerators from different enum types. (complex_divide_builtin_code): Likewise.
