From 1f5e6267aacce29ad21b0c2d072b6029ba6c14ac Mon Sep 17 00:00:00 2001 From: Alan Modra Date: Fri, 27 Jan 2023 15:32:06 +1030 Subject: Call bfd_close_all_done in ld_cleanup This is similar to "Call bfd_close_all_done in output_file_close", but with some code tidying in the pe/pep write_build_id functions. write_build_id is passed the output bfd as its parameter, so there is no need to go looking for the output bfd via link_info (and doing so will no longer work since I clear link_info.output_bfd before calling bfd_close). * emultempl/pe.em (write_build_id): Rename t to td. Formatting. Don't access pe_data(link_info.output_bfd), use td instead. (setup_build_id): Rename t to td. Formatting. * emultempl/pep.em: As for pe.em. * ldmain.c (ld_cleanup): Call bfd_close_all_done on linker bfds. (main): Clear link_info.output_bfd when closing. --- ld/emultempl/pe.em | 43 +++++++++++++++++++++++-------------------- ld/emultempl/pep.em | 41 ++++++++++++++++++++++------------------- ld/ldmain.c | 15 ++++++++++++--- 3 files changed, 57 insertions(+), 42 deletions(-) diff --git a/ld/emultempl/pe.em b/ld/emultempl/pe.em index 7e1866a23c7..55412d6ef9e 100644 --- a/ld/emultempl/pe.em +++ b/ld/emultempl/pe.em @@ -1300,7 +1300,7 @@ pecoff_checksum_contents (bfd *abfd, static bool write_build_id (bfd *abfd) { - struct pe_tdata *t = pe_data (abfd); + struct pe_tdata *td = pe_data (abfd); asection *asec; struct bfd_link_order *link_order = NULL; unsigned char *contents; @@ -1316,7 +1316,7 @@ write_build_id (bfd *abfd) { if (l->type == bfd_indirect_link_order) { - if (l->u.indirect.section == t->build_id.sec) + if (l->u.indirect.section == td->build_id.sec) { link_order = l; break; @@ -1335,15 +1335,16 @@ write_build_id (bfd *abfd) return true; } - if (t->build_id.sec->contents == NULL) - t->build_id.sec->contents = (unsigned char *) xmalloc (t->build_id.sec->size); - contents = t->build_id.sec->contents; + if (td->build_id.sec->contents == NULL) + td->build_id.sec->contents = xmalloc (td->build_id.sec->size); + contents = td->build_id.sec->contents; - build_id_size = compute_build_id_size (t->build_id.style); + build_id_size = compute_build_id_size (td->build_id.style); build_id = xmalloc (build_id_size); - generate_build_id (abfd, t->build_id.style, pecoff_checksum_contents, build_id, build_id_size); + generate_build_id (abfd, td->build_id.style, pecoff_checksum_contents, + build_id, build_id_size); - bfd_vma ib = pe_data (link_info.output_bfd)->pe_opthdr.ImageBase; + bfd_vma ib = td->pe_opthdr.ImageBase; #ifdef PDB_H if (pdb_name) @@ -1390,10 +1391,12 @@ write_build_id (bfd *abfd) cvinfo.CVSignature = CVINFO_PDB70_CVSIGNATURE; cvinfo.Age = 1; - /* Zero pad or truncate the generated build_id to fit in the CodeView record. */ + /* Zero pad or truncate the generated build_id to fit in the + CodeView record. */ memset (&(cvinfo.Signature), 0, CV_INFO_SIGNATURE_LENGTH); - memcpy (&(cvinfo.Signature), build_id, (build_id_size > CV_INFO_SIGNATURE_LENGTH) - ?
