-
-Commit
-
-eb2ea476db2 emit-rtl: Allow extra checks for paradoxical subregs [PR119966]
-
-changed validate_subreg to return false on the paradoxical SImode subreg
-of the OpenRISC condition flag register (reg:BI sr_f), which triggered
-
-internal compiler error: in emit_move_multi_word, at expr.cc:4497
-
-c0694f95f59 or1k: Fix ICE in libgcc caused by recent validate_subreg changes
-
-changed or1k_can_change_mode_class to allow changing flags mode from BI
-to SI. But or1k_hard_regno_mode_ok still returns false for condition
-flag register in SImode. Update or1k_hard_regno_mode_ok to also allow
-condition flag register in SImode.
-
-Tested with or1k Linux cross compiler for or1k glibc build.
