Richard Earnshaw <rearnsha at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Status|UNCONFIRMED |NEW Last reconfirmed| |2011-12-14 Ever Confirmed|0 |1 --- Comment #2 from Richard Earnshaw <rearnsha at gcc dot gnu.org> 2011-12-14 14:36:51 UTC --- Confirmed. The VCGT ..., #0 instruction only operates on signed types. Also applies to VCLE. Alternatives for unsigned are: - load 0 into a register - convert the comparison to VCEQ then, for GT only, invert the result.
