Comment at: clang/tools/clang-fuzzer/proto-to-llvm/loop_proto_to_llvm.cpp:125
std::ostream &operator<<(std::ostream &os, const LoopFunction &x) {
- return os << "define void @foo(i32* %a, i32* %b, i32* noalias %c, i64 %s)
{\n"
- << "%i = alloca i64\n"
- << "store i64 0, i64* %i\n"
- << "br label %loop\n\n"
- << "loop:\n"
- << "%ct = load i64, i64* %i\n"
- << "%comp = icmp eq i64 %ct, %s\n"
- << "br i1 %comp, label %endloop, label %body\n\n"
- << "body:\n"
+ return os << "target triple = \"x86_64-pc-linux-gnu\"\n"
+ << "define void @foo(i32*, i32*, i32*, i64) {\n"
----------------
What does `pc` mean in this triple? I'm used to seeing
`x86_64-unknown-linux-gnu`.

+ << "define void @foo(i32*, i32*, i32*, i64) {\n"
+ << "%5 = icmp sgt i64 %3, 0\n"
----------------
Does removing the variable names really make this easier to vectorize?

----------------
Does removing branch names really make this easier to vectorize?
