It is able to convert uint64 -> _Decimal128 though, for that .expand generates __bid_floatunsditd. ^ permalink raw reply [flat|nested] 3+ messages in thread

Initially I thought about doing this on the compiler side, but doing it on the library side seems to be easier and more -Os friendly. The tests currently require bitint effective target, that can be removed when all the int128 targets support bitint. 2023-11-09 Jakub Jelinek <jakub@redhat.com> PR libgcc/65833 libgcc/ * config/t-softfp (softfp_bid_list): Add {U,}TItype <-> _Decimal{32,64,128} conversions. * soft-fp/floattisd.c: New file. * soft-fp/floattidd.c: New file. * soft-fp/floattitd.c: New file. * soft-fp/floatuntisd.c: New file. * soft-fp/floatuntidd.c: New file. * soft-fp/floatuntitd.c: New file. * soft-fp/fixsdti.c: New file. * soft-fp/fixddti.c: New file. * soft-fp/fixtdti.c: New file. * soft-fp/fixunssdti.c: New file. * soft-fp/fixunsddti.c: New file. * soft-fp/fixunstdti.c: New file. gcc/testsuite/ * gcc.dg/dfp/int128-1.c: New test. * gcc.dg/dfp/int128-2.c: New test. * gcc.dg/dfp/int128-3.c: New test. * gcc.dg/dfp/int128-4.c: New test. ^ permalink raw reply [flat|nested] 3+ messages in thread
