Bug ID: 125362
Summary: [16 Regression] Missing
common/config/loongarch/cpu-features.h in installed
GCC plugin headers for LoongArch
Product: gcc
Version: 16.1.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: wszqkzqk at qq dot com
Target Milestone: ---
Target: loongarch64-unknown-linux-gnu
Host: loongarch64-unknown-linux-gnu
When compiling `linux-hardened` with GCC 16.1.0, the build fails with a missing
header error:
```
In file included from
/usr/lib/gcc/loongarch64-unknown-linux-gnu/16.1.1/plugin/include/tm_p.h:4,
from scripts/gcc-plugins/gcc-common.h:19,
from scripts/gcc-plugins/stackleak_plugin.c:30:
/usr/lib/gcc/loongarch64-unknown-linux-gnu/16.1.1/plugin/include/config/loongarch/loongarch-protos.h:25:10:
fatal error: common/config/loongarch/cpu-features.h: No such file or directory
25 | #include "common/config/loongarch/cpu-features.h"
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
```
The header cpu-features.h exists in the GCC source tree under
gcc/common/config/loongarch/, but it is not installed into the plugin include
directory during make install-plugin. This breaks compilation of any GCC plugin
that includes standard target headers.
