I thought I'd already filed this once before but couldn't find it while
searching, not even through closed bugs. On x86-32 without SSE, this testcase

$ llvm-as < c.ll | llc -mattr=-sse
llc: X86FloatingPoint.cpp:995:
Assertion `(StackTop == 1 || StackTop == 2) && "Stack should have one or two
element on it to return!"' failed.
0   llc 0x089a99e2
1   llc 0x089a9f89
2       0xffffe400 __kernel_sigreturn + 0
Stack dump:
0.      Program arguments: llc -mattr=-sse 
1.      Running pass 'X86 FP Stackifier' on function '@test'

It'd be awfully nice if that worked.
