gcc/ PR driver/68463 * config/gnu-user.h (CRTOFFLOADBEGIN): Define. Add crtoffloadbegin.o if offloading is enabled and -fopenacc or -fopenmp is specified. (CRTOFFLOADEND): Likewise. (GNU_USER_TARGET_STARTFILE_SPEC): Add CRTOFFLOADBEGIN. (GNU_USER_TARGET_ENDFILE_SPEC): Add CRTOFFLOADEND. * lto-wrapper.c (offloadbegin, offloadend): Remove static vars. (offload_objects_file_name): New static var. (tool_cleanup): Remove offload_objects_file_name file. (find_offloadbeginend): Replace with ... (find_crtoffloadtable): ... this. (run_gcc): Remove offload_argc and offload_argv. Get offload_objects_file_name from -foffload-objects=... option. Read names of object files with offload from this file, pass them to compile_images_for_offload_targets. Don't call find_offloadbeginend and don't pass offloadbegin and offloadend to the linker. Don't pass offload non-LTO files to the linker, because now they're not claimed. libgcc/ PR driver/68463 * Makefile.in (crtoffloadtable$(objext)): New rule. * configure.ac (extra_parts): Add crtoffloadtable$(objext) if enable_offload_targets is not empty. * configure: Regenerate. * offloadstuff.c: Move __OFFLOAD_TABLE__ from crtoffloadend to crtoffloadtable. libgomp/ PR driver/68463 * testsuite/libgomp.oacc-c-c++-common/parallel-dims-2.c: Remove. lto-plugin/ PR driver/68463 * lto-plugin.c (struct plugin_offload_file): New. (offload_files): Change type. (offload_files_last, offload_files_last_obj): New. (offload_files_last_lto): New. (free_2): Adjust accordingly. (all_symbols_read_handler): Don't add offload files to lto_arg_ptr. Don't call free_1 for offload_files. Write names of object files with offloading to the temporary file. Add new option to lto_arg_ptr. (claim_file_handler): Don't claim file if it contains offload sections without LTO sections. If it contains offload sections, add to the list. From-SVN: r233712
