COFF objects in particular don't contain the size of
symbols. We infer the size of these symbols by
extending them to the next symbol. If a tool emits
symbols for branch targets, this causes the inferred
size to be too small.
This checks if a symbol starts with a certain prefix
(right now, just .L or LAB_), and skips over it
during symbol size inference.
Resolves#174
Reworks the local-branch handling logic to be more
unified: scan_instructions does all the work up front,
and process_instruction / display_instruction can
simply use the calculated branch destination instead
of performing their own is-relocation-target-
function-local checks.
(Hopefully) Fixes#192
* Combine data/text sections: Pad all sections to 4-byte minimum alignment
* Update x86 test snapshot
* Read and store object section alignment
* Combine data/text sections: Pad sections to more than 4-byte alignment if they have alignment specified
Before, this was comparing, for example, `.text-2`
with `.text-10` with standard string comparison,
yielding `.text-10` before `.text-2`.
Instead, this simply uses a stable sort by name,
which preserves the relative ordering of sections.
* PPC: Calculate pooled relocations
Reimplements #140
The relocations are now generated when the object is first read in `parse`, right after the real relocations are read.
`resolve_relocation` was changed to take `obj.symbols` instead of `obj` as an argument, because `obj` itself doesn't exist yet at the time the relocations are being read.
* Improve readability of PPC pool relocs code
* Fix regression causing extern pool relocs to be ignored
* Fix showing incorrect diff when diffing weak stripped symbol with an addend
This is a regression that was introduced by #158 diffing addends in addition to symbol names. But it's not really a bug in that PR, rather it seems like I simply never added the offset into the addend when creating a fake pool relocation for an extern symbol. So this commit fixes that root issue instead.
* Add PPC "Calculate pooled data references" option
* Fix objdiff-wasm compilation errors
* Update PPC test snapshots
Implements MIPS relocation pairing logic.
New option for "Register '$' prefix", off by default.
Fixes various regressions introduced by refactoring.
