Bug ID: 28006
Summary: Linking 32-bit x86 binaries using gold drops the
.note.gnu.property section
Product: binutils
Version: unspecified
Status: NEW
Severity: normal
Priority: P2
Component: gold

Proposed patch
When linking 32-bit x86 binaries using the gold linker the .note.gnu.property
section is not created. The BFD linker on the other hand does create the
section.
For example:
% gcc -fcf-protection -m32 hello.c
% readelf --notes a.out | grep SHSTK
Properties: x86 feature: IBT, SHSTK
% gcc -fcf-protection -m32 hello.c -fuse-ld=gold
% readelf --notes a.out | grep SHSTK
%
A suggested patch is attached.
