Luke Street fd555a6e0f Fix reading little-endian .line section 2024-08-18 21:57:53 -06:00
Luke Street cad9b70632 Support protobuf format for reports
This migrates to using protobuf to
define the "report" and "changes"
formats in objdiff-cli.

The JSON output now uses the Proto3
"JSON Mapping", which is slightly
incompatible with the existing JSON
format. Mainly, 64-bit numbers are
represented as strings, and addresses
are decimal strings instead of hex.

However, the older JSON format is
still accepted by "report changes"
to ease migration.

Luke Street e1ccee1e73 Improve data section diffing more
This re-implements the older algorithm
used for data and BSS section match
percentages. We perform both and
choose the highest match percent
between the two options.

Steven Casper 09cc9952df Support R_MIPS_GPREL16 relocations correctly (#88)
* Support R_MIPS_GPREL16 relocations correctly

symbols defined in the same file require adding a
special ri_gp_value from the .reginfo section to
their relocation calculations.

* Run nightly rustfmt

* Prevent potential panic when slicing .reginfo
