I used a few more hours of my time on this. My conclusion is that "cc" clobber is completely ignored by clang. In fact, clang happily schedules carry-set and carry-use around inline asm with "cc".
This is another example that it's just a waste time trying to make GMP compile reliably with clang. See also Table 3 and the list below that table at https://gmplib.org/devel/tm/gmp/date.html for some context. Perhaps we could help clang's users by disabling GMP's inline asm altogether. It make things run a bit slower, but correctness is not optional, speed is. (We never enabled inline asm, it got enabled since clang claims to be gcc.) -- Torbjörn Please encrypt, key id 0xC8601622 _______________________________________________ gmp-bugs mailing list [email protected] https://gmplib.org/mailman/listinfo/gmp-bugs
