From: Iain Sandoe Date: Fri, 1 Sep 2023 08:04:13 +0000 (+0100) Subject: Darwin: Place global inits in the correct section. X-Git-Tag: releases/gcc-12.4.0~225 X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=11d379f5ff8a5d3ce3ec4bc2f66471cab15c9ff7;p=thirdparty%2Fgcc.git Darwin: Place global inits in the correct section. This handles placement of global initializers into __TEXT,__StaticInit as used by other platform toolchains. Signed-off-by: Iain Sandoe gcc/ChangeLog: * config/darwin-sections.def (static_init_section): Add the __TEXT,__StaticInit section. * config/darwin.cc (darwin_function_section): Use the static init section for global initializers, to match other platform toolchains.
