--- Comment #11 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The releases/gcc-13 branch has been updated by Jakub Jelinek <ja...@gcc.gnu.org>: https://gcc.gnu.org/g:9e27bc5a751dc61a1b2a2b13756ca07db8b209ee commit r13-9585-g9e27bc5a751dc61a1b2a2b13756ca07db8b209ee Author: Arsen ArsenoviÄ <ar...@aarsen.me> Date: Wed Jan 29 21:14:33 2025 +0100 d: give dependency files better filenames [PR118477] Currently, the dependency files for root-file.o and common-file.o were both d/.deps/file.Po, which would cause parallel builds to fail sometimes with: make[3]: Leaving directory '/var/tmp/portage/sys-devel/gcc-14.1.1_p20240511/work/build/gcc' make[3]: Entering directory '/var/tmp/portage/sys-devel/gcc-14.1.1_p20240511/work/build/gcc' mv: cannot stat 'd/.deps/file.TPo': No such file or directory make[3]: *** [/var/tmp/portage/sys-devel/gcc-14.1.1_p20240511/work/gcc-14-20240511/gcc/d/Make-lang.in:421: d/root-file.o] Error 1 shuffle=131581365 Also, this means that dependencies of one of root-file or common-file are missing when developing. After this patch, those two files get assigned dependency files d/.deps/root-file.Po and d/.deps/common-file.Po respectively, so match the actual object files in the d/ subdirectory. There are other files with similar conflicts (mangle-package.o, visitor-package.o for instance). 2025-01-29 Arsen ArsenoviÄ <ar...@aarsen.me> Jakub Jelinek <ja...@redhat.com> PR d/118477 * Make-lang.in (DCOMPILE, DPOSTCOMPILE): Use $(basename $(@F)) instead of $(*F). Co-Authored-By: Jakub Jelinek <ja...@redhat.com> (cherry picked from commit d9ac0ad1e9a4ceec2d354ac0368da7462bea5675)
