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.
