When --build-id=tree is selected, gold would schedule a set of tasks to run to compute md5 hashes in parallel on chunks of the file. The scheduling was done before the Write_after_input_sections_task ran, so if we are compressing debug sections, the output file will change size and be remapped to a new address, sometimes causing the build id computation to crash, but even when it doesn't crash, it wouldn't include the debug information in the hash computation. This patch delays the scheduling of the md5 tasks until after Write_after_input_sections_task. gold/ PR gold/17819 * gold.cc (queue_final_tasks): When --build-id=tree, queue a separate task to schedule the build id computation. * layout.cc (Hash_task::Hash_task): Remove build_id_blocker, add Output_file and offset. (Hash_task::run): Get and release the input views. (Hash_task::is_runnable): Always return NULL (always runnable). (Layout::queue_build_id_tasks): Remove. (Layout::write_build_id): Add array_of_hashes and size_of_hashes parameters; use them instead of class members. (Build_id_task_runner::run): New function. (Close_task_runner::run): Pass array_of_hashes and size_of_hashes to write_build_id. * layout.h (Layout::queue_build_id_tasks): Remove. (Layout::write_build_id): Add array_of_hashes and size_of_hashes parameters. (Layout::array_of_hashes_): Remove. (Layout::size_of_array_of_hashes_): Remove. (Layout::input_view_): Remove. (Build_id_task_runner): New class. (Close_task_runner::Close_task_runner): Add array_of_hashes and size_of_hashes parameters. (Close_task_runner::array_of_hashes_): New data member. (Close_task_runner::size_of_hashes_): New data member. * testsuite/Makefile.am (flagstest_compress_debug_sections_and_build_id_tree): New test. * testsuite/Makefile.in: Regenerate. -- You are receiving this mail because: You are on the CC list for the bug. _______________________________________________ bug-binutils mailing list bug-binutils@gnu.org https://lists.gnu.org/mailman/listinfo/bug-binutils
