説明

Describe the bug When using clang-cl and lld-link, b_lto is not recognized by meson.

$ meson configure -Db_lto=true

ERROR: Unknown options: "b_lto"

Expected behavior clang-cl and lld-link supporting link-time optimization, meson should be able to plug it in too.

system parameters

Windows 11, using CC=clang-cl; CXX=clang-cl (lld-link is set as the default linker)
Python 3.11.2
meson 1.4.0

推定時間: 1-3 hours
活動状況: fresh
明確さ: clear
前提条件: Familiarity with Meson build systemUnderstanding of link time optimizationKnowledge of clang cl and lld link
初心者向け度: 45
調査方針: The issue is a feature request to support b lto with clang cl and lld link. Start by examining how b lto is currently defined in the build option files, likely mesonbuild/options.py. Look at how compiler and linker detection works for other toolchains in mesonbuild/compilers/. Extend the logic to recognize clang cl and lld link and allow b lto. Check the one comment on the issue for any additional hints. After implementing, test with a sample project using clang cl and lld link on Windows.
