--- Comment #3 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Jakub Jelinek <ja...@gcc.gnu.org>: https://gcc.gnu.org/g:f172b9d38db426d2b102c0f9c1fd58672acc6c9b commit r14-5266-gf172b9d38db426d2b102c0f9c1fd58672acc6c9b Author: Jakub Jelinek <ja...@redhat.com> Date: Thu Nov 9 09:14:07 2023 +0100 libgcc: Add {unsigned ,}__int128 <-> _Decimal{32,64,128} conversion support [PR65833] The following patch adds the missing {unsigned ,}__int128 <-> _Decimal{32,64,128} conversion support into libgcc.a on top of the _BitInt support (doing it without that would be larger amount of code and I hope all the targets which support __int128 will eventually support _BitInt, after all it is a required part of C23) and because it is in libgcc.a only, it doesn't hurt that much if it is added for some architectures only in GCC 15. 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 <ja...@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.
