Since it is only supported for x86_64.
Checked on i686-linux-gnu.
‘--enable-cet=permissive’, CET is disabled when dlopening a non CET
enabled shared library in CET enabled application.
- NOTE: ‘--enable-cet’ has been tested for x86_64 and x32 on non-CET
- and CET processors.
+ NOTE: ‘--enable-cet’ is only supported on x86_64 and x32.
‘--enable-memory-tagging’
Enable memory tagging support if the architecture supports it.
Major new features:
-* Sync with Linux kernel 6.6 shadow stack interface. Since only x86-64
- is supported, --enable-cet is ignored for i386.
+* Sync with Linux kernel 6.6 shadow stack interface. The --enable-cet
+ configure option in only supported on x86-64.
* struct statvfs now has an f_type member, equal to the f_type statfs member;
on the Hurd this was always available under a reserved name,
