re PR driver/68463 (Offloading fails when some objects are compiled with LTO and some without)
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.
