commit r17-2655-gc17883e6f27a0960ba35fe059db639293b7ab909 Author: Rainer Orth <[email protected]> Date: Thu Jul 23 10:29:33 2026 +0200 testsuite: Provide shf_link_order effective target Like R_flag_in_section, the o_flag_in_section effective target is a misnomer. It actually signifies support for the SHF_LINK_ORDER section flag. Therefore this patch uses the et-static framework to determine it from HAVE_GAS_SECTION_LINK_ORDER in auto-host.h, adapting the existing uses. Bootstrapped without regressions on i386-pc-solaris2.11 and x86_64-pc-linux-gnu. 2026-01-13 Rainer Orth <[email protected]> gcc: * configure.ac (HAVE_GAS_SECTION_LINK_ORDER): Clarify comment. * config.in: Regenerate. * doc/sourcebuild.texi (Effective-Target Keywords) (o_flag_in_section): Rename to shf_link_order. Update description. gcc/testsuite: * lib/target-supports.exp (check_effective_target_o_flag_in_section): Remove. * lib/et-static.def (shf_link_order): New effective target. * g++.dg/pr93195a.C: Require shf_link_order. * gcc.dg/pr110729.c: Likewise.
