PR/32298 sframe: no SFrame stack trace info generated for .plt.got Add support to generate SFrame stack trace info for .plt.got section. Enhance the current definition of struct elf_x86_sframe_plt to include initialized SFrame FDE/FREs applicable for .plt.got section. There are two variants of .plt.got entries: 16 byte and 8 byte. 8 byte: ff 25 00 00 00 00 jmpq *name@GOTPCREL(%rip) 66 90 xchg %ax,%ax 16 byte: f3 0f 1e fa endbr64 ff 25 66 2f 00 00 jmpq *name@GOTPCREL(%rip) 66 0f 1f 44 00 00 nopw 0x0(%rax,%rax,1) For the testcase, define some application symbols such that their PLT entry is placed in .plt.got and ensure SFrame information is generated with and without -z ibtplt. ChangeLog: PR/32298 * bfd/elf64-x86-64.c (elf_x86_64_link_setup_gnu_properties): PLT GOT entry size is different for IBT vs non IBT PLTs. * bfd/elfxx-x86.c (enum dynobj_sframe_plt_type): New enum for SFRAME_PLT_GOT. (_bfd_x86_elf_create_sframe_plt): Handle SFRAME_PLT_GOT. (_bfd_x86_elf_write_sframe_plt): Likewise. (_bfd_x86_elf_late_size_sections): Likewise. (_bfd_x86_elf_finish_dynamic_sections): Likewise. * bfd/elfxx-x86.h (struct elf_x86_sframe_plt): Add new members to keep information about PLT GOT entries. (struct elf_x86_link_hash_table): Add support for creating SFrame section for .plt.got. * ld/testsuite/ld-x86-64/x86-64.exp: Add new tests. * ld/testsuite/ld-x86-64/sframe-pltgot-1.d: New test. * ld/testsuite/ld-x86-64/sframe-pltgot-1.s: New test. * ld/testsuite/ld-x86-64/sframe-pltgot-2.d: New test. |
