Bug ID: 22909
Summary: Expand --warn-shared-textrel support to all
executables, not only PIC objects
Product: binutils
Version: 2.30
Status: UNCONFIRMED
Severity: enhancement
Priority: P2
Component: ld
Assignee: unassigned at sourceware dot org
Reporter: slyfox at inbox dot ru
Target Milestone: ---
Gentoo enables --warn-shared-textrel by default for and extends warning to all
dynamic executables (PIE or not):
https://sources.gentoo.org/cgi-bin/viewvc.cgi/gentoo/src/patchsets/binutils/2.17/66_all_binutils-2.17.50.0.2-warn-textrel.patch?revision=1.1&view=markup
What do you think of extending this option (or adding new one) to cover
executables in upstream binutils?
Something like --warn-textrel.
Lack of TEXTREL warning came up recently in gcc where gcc was built with
TEXTRELs due to a platform-specific gcc bug:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=84553
The warning would be complementary to '-Wl,-z,-text' which converts problems of
this kind to errors.

warn-shared-textrel by default".
