[TextAPI] Track RPaths in the order its provided via command line. (#131665)

2025-03-19T05:12:45+00:00

RPaths are basically search paths for how to load dependent libraries.
The order they appear is the order the linker will search, we should
preserve that order in tbd files.

* Additionally add this level of detection to llvm-readtapi.

[readtapi] Condense output when comparing tbd files with mismatched inlined libraries (#129754)

2025-03-05T01:05:01+00:00

Previously, when an inlined library existed in TBD file A but not in file B, all of the inlined library's attributes were printed. This is noisy since the important detail is the complete contents are missing. Instead, only print the install name of the inlined library and the marker for which the input file exists in.

[TextAPI] Rename SymbolKind to EncodeKind (#79622)

2024-01-27T00:12:50+00:00

A distinction that doesn't _usually_ matter is that the
MachO::SymbolKind is really a mapping of entries in TBD files not
symbols. To better understand this, rename the enum so it represents an
encoding mapped to TBDs as opposed to symbols alone.

For example, it can be a bit confusing that "GlobalSymbol" is a enum
value when all of those values can represent a GlobalSymbol.

[readtapi] Add Merge functionality (#72656)

2023-11-17T20:26:04+00:00

Merge allows a user to merge different files (tbds for now or dylibs in
the future) to emit out a single tbd with all input contents. This does
require that all inputs represent the same library.

[llvm][TextAPI] Add new `not_for_dyld_shared_cache` attribute to file… (#71735)

2023-11-09T17:22:16+00:00

… format.

Formats >= TBDv4 will now encode new attribute that the system static
linker wil read when tbd files replace binary dylibs.

[llvm][ReadTAPI] Add & fix rpath comparison checks

2023-08-30T14:42:52+00:00

* Check and emit out differences in rpath inputs
* Prevent rpaths from being overwritten
* Capture file path for tbd-v5

[TextAPI] Make sortTargetValues strict weak ordering compliant

2023-08-21T15:56:39+00:00

Second sorting was not following strict weak ordering as it
does not follow transitivity of equivalence property.

If you build llvm with libcxx at head as a standard library with -D_LIBCPP_DEBUG_STRICT_WEAK_ORDERING_CHECK and -D_LIBCPP_ENABLE_DEBUG_MODE, then tests like llvm/test/tools/llvm-readtapi/compare-right-single-inline.test.test will fail

[TextAPI] Express MH_SIM_SUPPORT in tbd files.

2023-08-11T17:17:01+00:00

This adds a new optional flag sim_support which is the same as
MH_SIM_SUPPORT in the MachO header.

[llvm][tapi-diff] Transition diff-tool to be more general purpose

2023-07-31T16:32:26+00:00

This is the first of transition tapi-diff to be readtapi.
This tool will eventually replace functionality for Xcode's `xcrun tapi stubify` and
`xcrun tapi archive`.
This patch updates the tool name and is a minor refactor for the driver to handle more options.
