Reported by rajesh viswabramana on llvmdev, I just converted the test to IL:
-------------------------------------------
target triple = "i386-unknown-linux-gnu"
define double @func1() {
entry:
%0 = tail call double asm "", "=r,0,~{dirflag},~{fpsr},~{flags}"(double
undef)
ret double %0
}
--------------------------------------------
$ ./bin/llc test.ll
llc:
/home/espindola/llvm/llvm/lib/CodeGen/SelectionDAG/SelectionDAGBuilder.cpp:383:
void getCopyToParts(llvm::SelectionDAG &, llvm::DebugLoc, llvm::SDValue,
llvm::SDValue *, unsigned int, llvm::EVT, const llvm::Value *, ISD::NodeType):
Assertion `(PartVT.isInteger() || PartVT == MVT::x86mmx) && ValueVT.isInteger()
&& "Unknown mismatch!"' failed.
