From 24f50d7ea5896a30b0e78f68884586bb8b40ff97 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Andreas=20F=C3=A4rber?= Date: Sun, 27 May 2012 19:50:47 +0200 Subject: tcg/ppc: Handle _CALL_DARWIN being undefined on Darwin powerpc-apple-darwin9-gcc-4.2.1 (GCC) 4.2.1 (Apple Inc. build 5577) does not define _CALL_DARWIN, leading to unexpected behavior w.r.t. register clobbering and stack frame layout. Since _CALL_DARWIN is a reserved identifier, define a custom TCG_TARGET_CALL_DARWIN based on either _CALL_DARWIN or __APPLE__.
