Your patch is probably still useful. I think Kito's only concern was to make
sure we don't have the ANDI instruction in addition to not having the SEXT
instruction. So still approved for trunk, just update the testcases to make

We produce inefficient code for some synthesized SImode conditional set
operations (i.e. ones that are not directly implemented in hardware) on
RV64. For example a piece of C code like this:
int
sleu (unsigned int x, unsigned int y)
{
return x <= y;
}
gets compiled (at `-O2') to this:
sleu:
