From 4ce8d61a5cb8a0e3f68bff8400ba2b8246c9a58f Mon Sep 17 00:00:00 2001 From: Michael Brown Date: Mon, 30 Jul 2007 02:37:42 +0100 Subject: Import various libgcc functions from syslinux. Experimentation reveals that gcc ignores -mrtd for the implicit arithmetic functions (e.g. __udivdi3), but not for the implicit memcpy() and memset() functions. Mark the implicit arithmetic functions with __attribute__((cdecl)) to compensate for this. (Note: we cannot mark with with __cdecl, because we define __cdecl to incorporate regparm(0) as well.) --- src/core/gcc_implicit.c | 20 -------------------- 1 file changed, 20 deletions(-) delete mode 100644 src/core/gcc_implicit.c (limited to 'src/core') diff --git a/src/core/gcc_implicit.c b/src/core/gcc_implicit.c deleted file mode 100644 index 8f217b6d3..000000000 --- a/src/core/gcc_implicit.c +++ /dev/null @@ -1,20 +0,0 @@ -/** @file - * - * gcc implicit functions - * - * gcc sometimes likes to insert implicit calls to memcpy(). - * Unfortunately, there doesn't seem to be any way to prevent it from - * doing this, or to force it to use the optimised memcpy() as seen by - * C code; it insists on inserting a symbol reference to "memcpy".
