Hi For .LL like: define void @Func() { %var1 = alloca double store double 0x40bb580000000000, double* %var1 ret void } ppc32 output is: ... lis 3, 16571 ori 3, 3, 22528 li 4, 0 stw 3, 8(1) stw 4, 12(1) ... I'm using the PPC backend's output as the "bytecode" for an interpreter that I would like to be able to run on both little- and big-endian platforms. The split stw's mean that i32s of the f64 are swapped in memory on little-endian (thus foilin...
