commit b7eed1c7ce63044eae00fddef156c7fcb6b315b5 Author: Alexandre Oliva <[email protected]> Date: Tue Sep 9 23:28:32 2025 -0300 [aarch64] [testsuite] disable PIE for nonlocal_goto sme tests When an aarch64 toolchain is configured with --enable-default-pie, gcc.target/aarch64/sme/nonlocal_goto_[123].c fail because ira.cc's setup_reg_equiv resets function_invariant_p(x) equivalences when e.g. flag_pic and !CONSTANT_P (x), and then lra ends up unable to rematerialize stack addresses that would otherwise be rematerialized as small constants added to sp, and instead the addresses end up in pseudos assigned to stack slots. for gcc/testsuite/ChangeLog * gcc.target/aarch64/sme/nonlocal_goto_1.c: Force PIE off. * gcc.target/aarch64/sme/nonlocal_goto_2.c: Likewise. * gcc.target/aarch64/sme/nonlocal_goto_3.c: Likewise.
