commit r16-6814-g41ccca8fffd2359e5656490a85370740797a633c Author: David Guillen Fandos <[email protected]> Date: Thu Jan 15 00:45:37 2026 +0100 MIPS: Add R5900 to ISA_HAS_FMIN_FMAX. The R5900 doesn't have proper IEEE754 handling: for all its FP instructions, like "c.eq.s" or "add.s". Since most of the other instructions are also broken, so we can just define this, and the users should know about what they are doing. gcc/ChangeLog: * config/mips/mips.h (ISA_HAS_FMIN_FMAX): Add R5900; note that, R5900 is not IEEE754 fully compatiable.
