Subject: [PATCH v8 0/3] kbuild: distributed build support for Clang ThinLTO
Date: Mon, 30 Mar 2026 17:19:16 +0000 [thread overview]
Message-ID: <20260330171920.2026779-1-xur@google.com> (raw)
From: Rong Xu <xur@google.com>
ChangeLog:
V8: Disabled -always-rename-promoted-locals=false for the distrubute
mode, based on Yonghong and Nathan's comments.
V7: (1) Resolved a conflict by rebasing to kbuild/kbuild-next-unstable.
(2) Separated the '--thin' to 'T' change into its own patch to
preserve Masahiro's original version.
V6: Change '--thin' back to 'T' in Makefile.vmlinux_a to fix
reported the build error from old ar.
V5: Handle single quote escaping in echo _c_flags to fix
Piotr Gorski's reported error.
V4: This is based on the reimplementation provided by Masahiro Yamada
on May 26. The difference is that this version now saves the compiler
flags (_c_flags) from the Front-End (FE) compilation and re-uses them
for the subsequent Back-End (BE) compilation.
Rong Xu (3):
kbuild: move vmlinux.a build rule to scripts/Makefile.vmlinux_a
kbuild: change --thin back to 'T' in $(AR)
kbuild: distributed build support for Clang ThinLTO
