2018-12-05[aarch64] Add support for pointer authentication B keySam Tebbs1-16/+6
Armv8.3-A has another key used in pointer authentication called the B-key (other than the A-key that is already supported). In order for stack unwinders to work it is necessary to be able to identify frames that have been signed with the B-key rather than the A-key and it was felt that keeping this as an augmentation character in the CIE was the best bet. The DWARF extensions for ARM therefore propose to add a new augmentation character 'B' to the CIE augmentation string and the corresponding cfi directive ".cfi_b_key_frame". I've made the relevant changes to GAS and LD to add support for B-key unwinding, which required modifying LD to check for 'B' in the augmentation string, adding the ".cfi_b_key_frame" directive to GAS and adding a "pauth_key" field to GAS's fde_entry and cie_entry structs. The pointer authentication instructions will behave as NOPs on architectures that don't support them, and so a check for the architecture being assembled for is not necessary since there will be no behavioural difference between augmentation strings with and without the 'B' character on such architectures. 2018-12-05 Sam Tebbs <sam.tebbs@arm.com> bfd/ * elf-eh-frame.c (_bfd_elf_parse_eh_frame): Add check for 'B'. gas/ * dw2gencfi.c (struct cie_entry): Add tc_cie_entry_extras invocation.

2016-10-06Refine .cfi_sections check to only consider compact eh_frameMatthew Fortune1-1/+4
The .cfi_sections directive can be safely used multiple times with different sections named at any time unless the compact form of exception handling is requested after CFI information has been emitted. Only the compact form of CFI information changes the way in which CFI is generated and therefore cannot be retrospectively requested after generating CFI information. gas/ PR gas/20648 * dw2gencfi.c (dot_cfi_sections): Refine the check for inconsistent .cfi_sections to only consider compact vs non compact forms. * testsuite/gas/cfi/cfi-common-9.d: New file. * testsuite/gas/cfi/cfi-common-9.s: New file. * testsuite/gas/cfi/cfi.exp: Run new test.

2015-02-06gas: fix a few omissions in .cfi_label handlingJan Beulich1-1/+5
While actually starting to use that new directive, I noticed a few oversights of the original commit. gas/ 2015-02-06 Jan Beulich <jbeulich@suse.com> * dw2gencfi.c (select_cie_for_fde): Also bail on CFI_label. (cfi_change_reg_numbers): Also do nothing for CFI_label. (cfi_pseudo_table): Also handle .cfi_label when not supporting CFI directives.
2015-01-12gas: allow labeling of CFI instructionsJan Beulich1-1/+40
When runtime patching code (like e.g. done by the Linux kernel) there may be cases where the set of stack frame alterations differs between unpatched and patched code. Consequently the corresponding unwind data needs patching too. Locating the right places within an FDE, however, is rather cumbersome without a way to insert labels in the resulting section. Hence this patch introduces a new directive, .cfi_label. Note that with the way CFI data gets emitted currently (at the end of the assembly process) this can't support local FB- and dollar-labels. gas/ 2015-01-12 Jan Beulich <jbeulich@suse.com> * gas/dw2gencfi.c (cfi_add_label, dot_cfi_label): New. (cfi_pseudo_table): Add "cfi_label". (output_cfi_insn): Handle CFI_label. (select_cie_for_fde): Als terminate CIE when encountering CFI_label. * dw2gencfi.h (cfi_add_label): Declare.
