    • PR testsuite/85483: Move aarch64/sve/vcond_1.c test to g++.dg/other/ · db994ead 
      I totally botched up this sve test file in 259437.
It needs C++, so move it to g++.dg/other and make it a .C file.
Also adds the target guards to prevent it from running on non-aarch64 targets.

Tested that it passes on aarch64-none-elf and doesn't get run on arm-none-eabi.

Committing to trunk as obvious.

    • Define __CET__ for -fcf-protection and remove -mibt · e95dda95 
      With revision 259496:

commit b1384095a7c1d06a44b70853372ebe037b2f7867
Author: hjl <hjl@138bc75d-0d04-0410-961f-82ee72b054a4>

    x86: Enable -fcf-protection with multi-byte NOPs

-mibt does nothing and can be removed.  Define __CET__ to indicate level
protection with -fcf-protection:

(__CET__ & 1) != 0: -fcf-protection=branch or -fcf-protection=full
(__CET__ & 2) != 0: -fcf-protection=return or -fcf-protection=full
