--- Comment #20 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The releases/gcc-9 branch has been updated by H.J. Lu <h...@gcc.gnu.org>: https://gcc.gnu.org/g:ecdb697389b284a0f3912932e0a440c1071fbadd commit r9-9344-gecdb697389b284a0f3912932e0a440c1071fbadd Author: Prathamesh Kulkarni <prathamesh.kulka...@linaro.org> Date: Mon Feb 24 11:55:45 2020 +0530 PR47785: Add support for handling Xassembler/Wa options with LTO. Skip the test if arm7a is not supported at link time. This is the case if the toolchain targets an M-profile CPU by default and does not have A-profile multilib: the link step fails because it tries to mix M-profile startup files with A-profile testcase. gcc/ 2020-02-24 Prathamesh Kulkarni <prathamesh.kulka...@linaro.org> Kugan Vivekandarajah <kugan.vivekanandara...@linaro.org> PR driver/47785 * gcc.c (putenv_COLLECT_AS_OPTIONS): New function.
