* testsuite/libffi.call/cls_longdouble.c: Likewise.
* testsuite/libffi.call/huge_struct.c: Likewise.
+2010-08-04 Dan Witte <dwitte@mozilla.com>
+
+ * src/x86/ffitarget.h: Add X86_ANY define for all x86/x86_64
+ platforms.
+ * src/x86/ffi.c: Remove redundant ifdef checks.
+ * src/prep_cif.c: Push stack space computation into src/x86/ffi.c
+ for X86_ANY so return value space doesn't get added twice.
+
2010-07-22 Dan Witte <dwitte@mozilla.com>
* src/*/ffitarget.h: Make FFI_LAST_ABI one past the last valid ABI.
