--- Comment #18 from Oleg Endo <olegendo at gcc dot gnu.org> --- (In reply to Claudiu Zissulescu from comment #17) > Removing FLOAT_BIT_ORDER_MISMATCH seems it doesn't affect ARC backend as > well. Thanks for checking and confirming! The patch in attachment 41982 has been tested by Jeff's auto tester without problems: https://gcc.gnu.org/ml/gcc-patches/2019-10/msg00267.html Bernd raised a concern regarding bitfields and shift-and-ands, I've briefly checked it: https://gcc.gnu.org/ml/gcc-patches/2019-10/msg00824.html If there are no further objections, I'll commit it to trunk soon.
