I did an experiment just now with a test case like: // RUN: clang %s -S -emit-llvm -o %t.ll // RUN: llc %t.ll -o %t.s // RUN: FileCheck < %t.s %s ... // CHECK: ... And it worked. It seems clang does not take stdin as its input, so "clang < %s" fails. Meanwhile, both "llc < %t.ll" and "llc %t.ll" work. 2012/8/22 Triple Yang <triple.yang at
