https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=223752 --- Comment #19 from Mark Millard <markmi@dsl-only.net> --- (In reply to dstaesse from comment #18) You are welcome. My guess is that this is outside POSIX completely and is just ABI material for what you are doing. In fact, looking around I found an ARM document indicating an empty parameter list for its .init_array context: Each translation unit provides a fragment of the constructor vector in an ELF section called .init_array of type SHT_INIT_ARRAY (=0xE) and section flags SHF_ALLOC + SHF_WRITE. Each element of the vector contains the address of a function of type extern “C” void (* const)(void) that, when called, performs part or all of the global object construction for the translation unit. Producers must treat .init_array sections as if they were read-only. ( http://infocenter.arm.com/help/topic/com.arm.doc.ihi0041e/IHI0041E_cppabi.pdf page 19 of 24.) So, not portable across all ABIs that have .init_array . -- You are receiving this mail because: You are the assignee for the bug.
