[PATCH] D102918: [RISCV] Avoid undef result due to promotion of FPOWI exponent

[Craig Topper via Phabricator via llvm-commits]

craig.topper added a comment.

Where is it documented that larger than i32 is undefined? I see this in ISDOpcodes.def

For FPOWI, the result is undefined if if the integer operand doesn't fit into 32 bits.

That sounds more like it’s talking about the range of the value than the type. So why isn’t it ok to sign extend  i32 to i64?
