Subject: [PATCH 1/7] [compiler-rt][profile] Add initial support for
 WebAssembly/WASI

This patch adds initial support for WebAssembly/WASI to the profile
runtime library on the top of wasi-libc. This is a part of the ongoing
patch series to add coverage support for WebAssembly/WASI.

The patch includes the following changes:
* Add wasm32-wasi to the list of supported architectures/OSes.
* Exclude unsupported features for WASI: flock, madvise, uname.
* Enable some user-space emulation provided by wasi-libc: mmap, getpid

Subject: [PATCH 1/8] [compiler-rt][profile] Add initial support for
 WebAssembly/WASI

This patch adds initial support for WebAssembly/WASI to the profile
runtime library on the top of wasi-libc. This is a part of the ongoing
patch series to add coverage support for WebAssembly/WASI.

The patch includes the following changes:
* Add wasm32-wasi to the list of supported architectures/OSes.
* Exclude unsupported features for WASI: flock, madvise, uname.
* Enable some user-space emulation provided by wasi-libc: mmap, getpid

[clang] [compiler-rt] [lld] [llvm] [Coverage][WebAssembly] Add initial support for WebAssembly/WASI (PR #111332)

2024-10-06 Thread Yuta Saito via cfe-commits 

https://github.com/kateinoigakukun created 
https://github.com/llvm/llvm-project/pull/111332

Currently, WebAssembly/WASI target does not provide direct support for code 
coverage.
This patch set fixes several issues to unlock the feature. The main changes are:

1. Port `compiler-rt/lib/profile` to WebAssembly/WASI.
2. Adjust profile metadata sections for Wasm object file format.
- [CodeGen] Emit `__llvm_covmap` and `__llvm_covfun` as custom sections 
instead of data segments.
- [lld] Align the interval space of custom sections at link time.
- [llvm-cov] Copy misaligned custom section data if the start address is 
not aligned.
- [llvm-cov] Read `__llvm_prf_names` from data segments
3. [clang] Link with profile runtime libraries if requested

See each commit message for more details and rationale.
