| 2025-09-30 | std.debug: significantly speed up capturing stack traces | mlugg | |
| By my estimation, these changes speed up DWARF unwinding when using the self-hosted x86_64 backend by around 7x. There are two very significant enhancements: we no longer iterate frames which don't fit in the stack trace buffer, and we cache register rules (in a fixed buffer) to avoid re-parsing and evaluating CFI instructions in most cases. Alongside this are a bunch of smaller enhancements, such as pre-caching the result of evaluating the CIE's initial instructions, avoiding re-parsing of CIEs, and big simplifications to the `Dwarf.Unwind.VirtualMachine` logic. | |||
| 2025-09-30 | fix aarch64-macos DWARF unwinding | mlugg | |
| turns out this isn't technically specific to that target at all; other targets just don't emit mid-function 'ret' instructions as much so certain CFI instruction patterns were only seen on aarch64. thanks to jacob for finding the bug <3 | |||
