[Object] Add getRISCVVendorRelocationTypeName to render RISCV vendor-specific relocations to strings. (#168293)

2025-11-17T00:21:46+00:00

This will be used in places like LLD to render them for error messages.

[SHT_LLVM_BB_ADDR] Implement ELF and YAML support for Propeller CFG data in PGO analysis map. (#164914)

2025-10-30T20:12:06+00:00

This PR implements the ELF support for PostLink CFG in PGO analysis map
as discussed in
[RFC](https://discourse.llvm.org/t/rfc-extending-the-pgo-analysis-map-with-propeller-cfg-frequencies/88617/2).

A later PR will implement the Codegen Support.

[llvm] Update call graph ELF section type. (#164461)

2025-10-22T22:08:36+00:00

Make call graph section to have a dedicated type instead of the generic
progbits type.

Adding Matching and Inference Functionality to Propeller (#160706)

2025-10-14T17:34:14+00:00

We have optimized the implementation of introducing the "matching and
inference" technique into Propeller. In this new implementation, we have
made every effort to avoid introducing new compilation parameters while
ensuring compatibility with Propeller's current usage. Instead of
creating a new profile format, we reused the existing one employed by
Propeller. This new implementation is fully compatible with Propeller's
current usage patterns and reduces the amount of code changes. For
detailed information, please refer to the following RFC:
https://discourse.llvm.org/t/rfc-adding-matching-and-inference-functionality-to-propeller/86238.
We plan to submit the relevant changes in several pull requests (PRs).
The current one is the first PR, which adds the basic block hash to the
SHT_LLVM_BB_ADDR_MAP section.

[SHT_LLVM_BB_ADDR_MAP] Change the callsite feature to emit end of callsites. (#155041)

2025-08-25T17:17:29+00:00

This PR simply moves the callsite anchors from the beginning of
callsites to their end.

Emitting the end of callsites is more sensible as it allows breaking the
basic block into subblocks which end with control transfer instructions.

Add section type to support CFI jump table relaxation.

[SHT_LLVM_BB_ADDR_MAP] Cleanup old version support code from ELF.cpp.

2025-07-02T20:01:43+00:00

This change was mistakenly dropped from the prior commit 6b623a6622707ea47d84ab0069f766215a6fec44

[SHT_LLVM_BB_ADDR_MAP] Remove support for versions 1 and 0 (SHT_LLVM_BB_ADDR_MAP_V0). (#146186)

2025-07-02T17:31:52+00:00

Version 2 was added more than two years ago
(https://github.com/llvm/llvm-project/commit/6015a045d768feab3bae9ad9c0c81e118df8b04a).
So it should be safe to deprecate older versions.
