--- Comment #4 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Iain D Sandoe <ia...@gcc.gnu.org>: https://gcc.gnu.org/g:d1d144d80f27f7a027ec8a05758555e7aa45462f commit r14-8522-gd1d144d80f27f7a027ec8a05758555e7aa45462f Author: Iain Sandoe <i...@sandoe.co.uk> Date: Wed Jan 24 08:05:01 2024 +0000 testsuite, GDC: Update link flags [PR112861]. The regressions here are because we do not generate a runpath for the uninstalled libstdc++. This patch updates the link flags handling to simplify it. We need to add options to locate both libgphobos and libstdc++ Usually '-L' options are added to point to the relevant directories for the uninstalled libraries. In cases where libraries are available as both shared and convenience some additional checks are made. For some targets -static-xxxx options are handled by specs substitution and need a '-B' option rather than '-L'. For Darwin, when embedded runpaths are in use (the default for all versions after macOS 10.11), '-B' is also needed to provide the runpath. When '-B' is used, this results in a '-L' for each path that exists (so that appending a '-L' as well is a needless duplicate). There are also cases where tools warn for duplicates, leading to spurious fails. Therefore the objective is to add a single -B/-L option for each needed path. PR target/112861 gcc/testsuite/ChangeLog: * lib/gdc.exp: Decide on whether to present -B or -L to reference the paths to uninstalled libphobos and libstdc++ and use that to generate the link flags.
