While the uitofp scalar constant folding treats an integer as an unsigned value (from lang ref): %X = sitofp i8 -1 to double ; yields double:-1.0 %Y = uitofp i8 -1 to double ; yields double:255.0 The vector constant folding was always using sitofp: %X = sitofp <2 x i8> <i8 -1, i8 -1> to <2 x double> ; yields <double -1.0, double -1.0> %Y = uitofp <2 x i8> <i8 -1, i8 -1> to <2 x double> ; yields <double -1.0, double -1.0> This patch fixes this so that the correct opcode is used for sitofp and uitofp. %X = sitofp <2 x i8> <i8 -1, i8 -1> to <2 x double> ; yields <double -1.0, double -1.0> %Y = uitofp <2 x i8> <i8 -1, i8 -1> to <2 x double> ; yields <double 255.0, double 255.0> Differential Revision: http://reviews.llvm.org/D8560 llvm-svn: 233033 |
