From 44c8d1a2a8775ad8c67fa1c46ccc67cccf585d93 Mon Sep 17 00:00:00 2001 From: Roland McGrath Date: Fri, 1 Sep 1995 22:25:08 +0000 Subject: Fri Sep 1 16:16:12 1995 Roland McGrath * libc-symbols.h (link_warning): Take new first arg SYMBOL; ask for a warning on references to that specific symbol, not the entire containing object file. (stub_warning): Pass symbol name to link_warning. * stdio/gets.c: Pass function name in link_warning invocation. * hurd/intr-msg.c: Treat apparent EINTR return from msg trap like MACH_SEND_INTERRUPTED. That indicates interrupt_operation was sent, but failed. * stdlib/msort.c: Include memcopy.h. (msort_with_tmp): If operating on aligned op_t words, use direct word fetches and stores. * sysdeps/i386/dl-machine.h (ELF_MACHINE_BEFORE_RTLD_RELOC): Add missing backslash. --- libc-symbols.h | 20 ++++++++++---------- 1 file changed, 10 insertions(+), 10 deletions(-) (limited to 'libc-symbols.h') diff --git a/libc-symbols.h b/libc-symbols.h index 7cc67a2b7e..8030abb089 100644 --- a/libc-symbols.h +++ b/libc-symbols.h @@ -155,27 +155,27 @@ Cambridge, MA 02139, USA. */ -/* When the file using this macro is linked in, the linker - will emit a warning message MSG. */ +/* When a reference to SYMBOL is encountered, the linker will emit a + warning message MSG. */ #ifdef HAVE_GNU_LD #ifdef HAVE_ELF -#define link_warning(msg) \ - static const char __evoke_link_warning__[] \ - __attribute__ ((section (".gnu.warning"))) = msg; +#define link_warning(symbol, msg) \ + static const char __evoke_link_warning_##symbol[] \ + __attribute__ ((section (".gnu.warning." #symbol))) = msg; #else -#define link_warning(msg) \ +#define link_warning(symbol, msg) \ asm(".stabs \"" msg "\",30,0,0,0\n" \ - ".stabs \"__evoke_link_warning__\",1,0,0,0\n"\ - ".stabs \"__evoke_link_warning__\",2,0,0,0\n"); + ".stabs \"" __SYMBOL_PREFIX #symbol "\",1,0,0,0\n"); #endif #else /* We will never be heard; they will all die horribly. */ -#define link_warning(msg) +#define link_warning(symbol, msg) #endif /* A canned warning for sysdeps/stub functions. */ #define stub_warning(name) \ - link_warning ("warning: " #name " is not implemented and will always fail") + link_warning (name, \ + "warning: " #name " is not implemented and will always fail") /* -- cgit 1.4.1
