Hi Dong, try turning optimizations on. I get the select then: > └─[$]› echo 'int min(int a, int b) { return a < b ? a : b; }' | clang -xc -O1 -S -emit-llvm -o - - > ; ModuleID = '-' > target datalayout = "e-p:64:64:64-i1:8:8-i8:8:8-i16:16:16-i32:32:32-i64:64:64-f32:32:32-f64:64:64-v64:64:64-v128:128:128-a0:0:64-s0:64:64-f80:128:128-n8:16:32:64-S128" >

...think that in LLVM IR, i can use a branch and two seperate assignments to replace 'select' instruction(am i right?). so is there any compiling option to aviod generate 'select' instruction? -- View this message in context: http://llvm.1065342.n5.nabble.com/llvm-select-instruction-tp56719p56726.html Sent from the LLVM - Dev mailing list archive at Nabble.com.

hello guys: i am thinking about what kind of C instructions can turn into llvm IR 'select' instruction. i tried "d=a?b:c" and compiled it using clang, i still didn't get 'select' is there anybody who knows this? thank you -- View this message in context: http://llvm.1065342.n5.nabble.com/llvm-select-instruction-tp56719.html Sent from the LLVM - Dev mailing list
