--- Comment #10 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The releases/gcc-11 branch has been updated by Peter Bergner <berg...@gcc.gnu.org>: https://gcc.gnu.org/g:5ede37c0f274f0de19afd662588891e32b60f705 commit r11-9836-g5ede37c0f274f0de19afd662588891e32b60f705 Author: Peter Bergner <berg...@linux.ibm.com> Date: Tue Apr 12 14:08:53 2022 -0500 rs6000: Handle pcrel sibcalls to longcall functions [PR104894] Before PCREL in POWER10, we were not allowed to perform sibcalls to longcall functions since callee's return would skip the TOC restore in the caller. However, with PCREL we can now safely perform a sibling call to longcall functions. The problem with the current code is that pcrel sibcall branches to a PLT stub label even though -fno-plt was used. The solution here is to check for a pcrel longcall and emit an inline plt stub in that case. 2022-04-11 Peter Bergner <berg...@linux.ibm.com> gcc/ PR target/104894 * config/rs6000/rs6000.c (rs6000_sibcall_aix): Handle pcrel sibcalls to longcall functions. gcc/testsuite/ PR target/104894 * gcc.target/powerpc/pr104894.c: New test. * gcc.target/powerpc/pr104894-2.c: New test.
