| 2024-08-22 | Dwarf: cleanup emitted debug info | Jacob Young | |
| * reduce iteration cost by not tracking unused entries * avoid emitting unused abbrevs to `.debug_abbrev` * get the compiler executable passing `llvm-dwarfdump --verify` * make it possible to skip `.debug_line` padding much more quickly | |||
| 2024-08-16 | Dwarf: rework self-hosted debug info from scratch | Jacob Young | |
| This is in preparation for incremental and actually being able to debug executables built by the x86_64 backend. | |||
| 2024-08-01 | std: dwarf namespace reorg | Andrew Kelley | |
| std.debug.Dwarf is the parsing/decoding logic. std.dwarf remains the unopinionated types and bits alone. If you look at this diff you can see a lot less redundancy in namespaces. | |||
| 2024-07-10 | dwarf: use StackIterator.MemoryAccessor to check memory accesses instead of ↵ | kcbanner | |
| isValidMemory | |||
| 2024-06-23 | Rename *[UI]LEB128 functions to *[UI]leb128 | Michael Bradshaw | |
| 2024-05-11 | riscv: remove an allocation from `dwarf.zig` | David Rubin | |
| 2024-03-19 | extract std.posix from std.os | Andrew Kelley | |
| closes #5019 | |||
| 2024-03-14 | std: make std.dwarf.FixedBufferReader public | Luuk de Gram | |
| Also fixes a compile-error as the field `is_64` no longer exists. | |||
| 2024-03-10 | improve documentation in std | Andrew Kelley | |
| A lot of these "shorthand" doc comments were redundant, low quality filler content. Better to let the actual modules speak for themselves with top level doc comments rather than trying to document their aliases. | |||
| 2024-02-18 | dwarf: optimize dwarf parsing for speed | Jacob Young | |
| This code is run when printing a stack trace in a debug executable, so it has to be fast even without compiler optimizations. Adding a `@panic` to the top of `main` and running an x86_64 backend compiled compiler goes from `1m32.773s` to `0m3.232s`. | |||
| 2023-11-19 | lib: correct unnecessary uses of 'var' | mlugg | |
| 2023-10-31 | mem: fix ub in writeInt | Jacob Young | |
| Use inline to vastly simplify the exposed API. This allows a comptime-known endian parameter to be propogated, making extra functions for a specific endianness completely unnecessary. | |||
| 2023-08-06 | std: remove some unused imports (#16710) | Zachary Raineri | |

| 2023-07-20 | dwarf: write the CFA as SP before the register update, in case the SP itself ↵ | kcbanner | |
| is updated by a column rule | |||
| 2023-07-20 | macho: don't scan all eh_frame entries, instead follow the offset from the ↵ | kcbanner | |

| 2023-07-20 | dwarf: use cie.return_address_register instead of assuming it's in the IP ↵ | kcbanner | |

| dwarf: fixup x86 register mapping logic dwarf: change the register context update to update in-place instead of copying debug: always print the unwind error type | |||
| 2023-07-20 | dwarf: don't dupe function names, as they are backed by the memory mapped ↵ | kcbanner | |
| sections dwarf: const-correctness fixups dwarf: implement the remaining register rules dwarf: start implmenting the DWARF expression stack machine | |||
| 2023-07-20 | debug: rework how unwind errors are printed, and add module name lookup for ↵ | kcbanner | |
| linux This change enhances stack trace output to include a note that debug info was missing, and therefore the stack trace may not be accurate. For example, if the user is using a libc compiled with -fomit-frame-pointer and doesn't have debug symbols installed, any traces that begin in a libc function may not unwind correctly. This allows the user to notice this and potentially install debug symbols to improve the output. | |||
| 2023-07-20 | dwarf: add support for DWARF5 DW_AT_ranges in subprograms, add ↵ | kcbanner | |
| DebugRangeIterator Some DWARF5 subprograms have non-contiguous instruction ranges. An example of such a function is `puts` in Ubuntu's libc. This change fixes name lookups for functions that use DW_AT_range in their DIE. | |||
| 2023-07-20 | dwarf: fix logic error in eh_frame_hdry binary search | kcbanner | |
| 2023-07-20 | debug: x86 unwinding support, more unwinding fixes | kcbanner | |
