From: Thomas Schwinge <tschwinge@gcc.gnu.org> To: gcc-cvs@gcc.gnu.org Subject: [gcc r13-319] libgomp GCN plugin: Clean up unused references to system-provided HSA Runtime library Date: Wed, 11 May 2022 12:32:17 +0000 (GMT) [thread overview] Message-ID: <20220511123217.70AA4385E021@sourceware.org> (raw) https://gcc.gnu.org/g:d6adba307508c75f1ccb2121eb1a43c9ab1d4056 commit r13-319-gd6adba307508c75f1ccb2121eb1a43c9ab1d4056 Author: Thomas Schwinge <thomas@codesourcery.com> Date: Wed Apr 6 11:31:45 2022 +0200 libgomp GCN plugin: Clean up unused references to system-provided HSA Runtime library This is only active if GCC is 'configure'd with '--with-hsa-runtime=[...]' or '--with-hsa-runtime-include=[...]', '--with-hsa-runtime-lib=[...]' -- which nobody really is doing, as far as I can tell. Originally changed for the libgomp HSA plugin in commit b8d89b03db5f212919e4571671ebb4f5f8b1e19d (r242749) "Remove build dependence on HSA run-time", and later propagated into the GCN plugin, these are no longer built against system-provided HSA Runtime library. Instead, unconditionally built against the GCC-shipped 'include/hsa*.h' header files, and at run time does 'dlopen("libhsa-runtime64.so.1")'. It thus doesn't make sense to consider references to system-provided HSA Runtime library during libgomp GCN plugin build. libgomp/ * plugin/configfrag.ac (HSA_RUNTIME_CPPFLAGS) (HSA_RUNTIME_LDFLAGS): Remove. * configure: Regenerate.
