Bug ID: 38192
Summary: [PowerPC] Clang biases __builtin_xxpermdi differently
from GCC on LE
Product: libraries
Version: trunk
Hardware: PC
OS: All
Status: NEW
Severity: enhancement
Priority: P
Component: Backend: PowerPC
Assignee: unassignedb...@nondot.org
Reporter: nemanja.i....@gmail.com
CC: llvm-bugs@lists.llvm.org
Calls to these builtins produce different results with the two compilers. Clang
needs to change to apply the same bias as GCC does.
vector short test0(vector short a, vector short b) {
return vec_xxpermdi(a, b, 0);
}
vector short test1(vector short a, vector short b) {
return vec_xxpermdi(a, b, 1);
}
vector short test2(vector short a, vector short b) {
return vec_xxpermdi(a, b, 2);
}
vector short test3(vector short a, vector short b) {
return vec_xxpermdi(a, b, 3);
}
