Bug ID: 116457
Summary: Add -frandomize-layout-seed and
-frandomize-layout-seed-file
Product: gcc
Version: 15.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c

Target Milestone: ---
The Linux kernel uses a GCC plugin ("randstruct") to randomise struct layout to
make certain attacks harder.
Clang implemented -frandomize-layout-seed and -frandomize-layout-seed-file
instead.
Implementing these in GCC would allow killing the use of another plugin. The
main issue with the plugin approach is the awkward interaction with generation
of debug info (PR84052).
