* [libgcc] Provide symbol to handle gcc's implicit calls to memset()Michael Brown2016-04-202-18/+26
| | | | | | | | On some architectures (such as ARM), gcc will insert implicit calls to memset(). Handle these using the same mechanism as for the implicit calls to memcpy() used by x86. Signed-off-by: Michael Brown <mcb30@ipxe.org>
* [build] Mark __intel_new_proc_init with __libgcc rather than cdeclMichael Brown2009-08-031-1/+1
| | | | | | | | | | The function __intel_new_proc_init() (called implicitly when building using icc) is marked with __attribute__((cdecl)). This breaks building on x86_64, where cdecl is meaningless. Fix by replacing with the existing __libgcc macro, which is already defined to be "__attribute__((cdecl))" for i386 builds and empty for x86_64 builds.

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.)
