--- Comment #10 from Iain Sandoe <iains at gcc dot gnu.org> 2010-12-13 20:16:23 UTC --- perhaps it would be safer to name the fallback section: >> : darwin_sections[text_unlikely_fallback_section]); >> DEF_SECTION (text_unlikely_fallback_section, SECTION_CODE|SECTION_NO_ANCHOR, ".section __TEXT,__unlikely_flbk,regular,pure_instructions", 0) (limit of 16chars for the section name == "unlikely fallback" ) then there's no danger of a section name clash when someone tries to build named_section ( "__TEXT,__unlikely,regular,pure_instruction", .... ) (If the regtest works w/out this, then perhaps not necessary ... )
