Alastair Houghton	78702e64cb	[Backtracing] Fix struct packing for PE-COFF definitions. ... Due to unfortunate structure packing rules in C, `struct pe_symbol` ends up being 20 bytes instead of 18. The upshot is that when presented with a PE-COFF binary that contains symbols (noting that this is actually a spec violation), the backtracer will crash. Unfortunately we often generate such binaries. We shouldn’t crash, though, and the fix is to get the correct size for `struct pe_symbol`. rdar://171711254	2026-03-04 12:18:56 +00:00
Alastair Houghton	e0845e1483	[Backtracing] Made on-crash backtraces work for 64-bit. ... On-crash backtracing is basically there for 64-bit Windows. It won't work on 32-bit because of a Swift compiler issue, and there is a little more work to do yet, but it is now working! rdar://101623384	2026-02-03 18:23:29 +00:00
Alastair Houghton	3cdac64200	[Backtracer] Fix some bugs that prevented DWARF reading. ... This is now fetching symbols successfully, though not line numbers yet. rdar://101623384	2026-02-03 18:23:29 +00:00
Alastair Houghton	7f57385be4	[Backtracing][Windows] Add PE file parsing and DWARF-in-PE support. ... This should allow us to get symbolicated backtraces for Swift code that is built with DWARF debug information. rdar://181623384	2026-02-03 18:23:29 +00:00
