* Make SHF_COMPRESSED use contingent on its existenceStephen Webb2020-07-021-0/+4
| | | | | | | | | | A recent change broke builds for many non-recent and non-Linux targets by adding code dependent on a non-portable preprocessor macro SHF_COMPRESSED found in some more recent GLIBC elf.h headers. This fixes the firt part of #190. Signed-off-by: Stephen Webb <swebb@blackberry.com>

| | | | | | | | Make sure to unmap the currently mapped elf image before mapping another image in CD_get_proc_name. If not, the reference to that image is lost and the memory is leaked.

* x86_64: Add fixup code if previous RIP was invalid (#120)Brock York2019-06-124-30/+210
| | | | | | | | | | | | * x86_64: Add fixup code if previous RIP was invalid Previous RIP could become invalid if a bad function pointer was followed. Calling unwind from a signal frame in this case skips the frame that called the bad pointer. Check if the value at RSP looks to be valid in this case. It should be the value of RIP pushed to the stack by the CALL instruction. If it looks valid use this value as the next frames RIP else fallback to the previous method.

* Added braces to suppress empty if/else warnings (#112)Stephen Roberts2019-04-243-9/+20
| | | | This change fixes all empty if/else block warnings from gcc. It does not change the functionality of libunwind in any way.
* mips: make _step_n64 as a static functionsnyh2019-04-111-50/+56
| | | | | | | | | | | 1. hidden _step_n64 to avoid a strange bug which will reproduce under `perf report`. The value `tdep_init_done` of suddenly be changed to zero when entering `_step_n64` from `unw_step`. 2. refactor code to improve the readability. use `FP_REG`, `SP_REG` and `RA_REG` to abstract the guessing logical.
* x86_64: Fix tdep_init_done when built with libatomic_opsDave Watson2019-04-112-1/+9

* Fixed a missing dependency in dwarf-eh.h Stephen Roberts2019-02-211-0/+1
| | | | | The dwarf-eh.h header is not self-contained, which causes problems depending on which order headers are included. In particular, it references the Elf_W macro but does not include its definition. If dwarf-eh.h is included after dwarf_i.h everything works, but if you reverse this order you get compile errors. This patch removes the implicit header ordering dependency by making sure the definition of Elf_W is visible in dwarf-eh.h. I include libunwind_i.h rather than the elfxx.h files directly because libunwind_i.h contains macro logic to choose which elf header to include, and I didn't want to duplicate that.
* dwarf: clang doesn't respect the static alias (#102)Dave Watson2019-01-091-0/+5
| | | | | Clang doesn't respect the static alias, resulting in global instead of local symbols, and name collisions. Work around for clang by always going through the PLT (at a small perf hit)

* Convert the README to markdown syntax (#96)Alex Arslan2018-12-111-105/+99
| | | | | | | | | | | | Currently the README's formatting shows up rather poorly on GitHub, as the file isn't written as a Markdown document but GitHub tries to render it as one due to the symlink from README.md to README. This commit reformats the file as a Markdown document, preserving the original content with two exceptions: 1. The platform support list has been converted to a Markdown table. 2. The severely outdated information regarding libexecinfo on FreeBSD has been amended and the note about FreeBSD 8.0 removed.
* dwarf: Push correct CFA onto stack for dwarf expression evaluation. (#93)Stephen Roberts2018-11-138-12/+190
| | | | | | | | dwarf: Push correct CFA onto stack for dwarf expression evaluation. This change fixes a bug where stale CFAs were pushed onto the dwarf expression stack before expression evaluation. Some optimising compilers emit CFI which relies on this being correct.
* dwarf: Add missing opcodes to the operands table in Gexpr.cStephen Roberts2018-10-121-0/+2
| | | This patch adds two opcodes to the operands table in Gexpr.c, which is a mapping between opcodes and the number and types of the operands for those opcodes. Two opcodes, DW_OP_constu and DW_OP_consts are missing from this table, which caused failures later in the CFI expression parsing logic. This patch adds the missing information into the table, and thus allows correct parsing of CFA_def_cfa_expression, CFA_expression and CFA_val_expression expressions which contain the offending opcodes.
