Reapply r57699 with a fix to not crash on asms with multiple results. Unlike the previous patch this one actually passes make check. "Fix PR2356 on PowerPC: if we have an input and output that are tied together that have different sizes (e.g. i32 and i64) make sure to reserve registers for the bigger operand." llvm-svn: 57771 2008-10-18 20:49:30 +02:00			`; RUN: llvm-as < %s \| llc`
We have decided not to support inline asm where an output operand with a matching input operand with incompatible type (i.e. either one is a floating point and the other is an integer or the sizes of the types differ). SelectionDAGBuild will catch these and exit with an error. llvm-svn: 61092 2008-12-16 19:21:39 +01:00			`; XFAIL: *`
