The LLVM Project is a collection of modular and reusable compiler and toolchain technologies.
`SLPVectorizer` transforms the following input `@src` into `@tgt`. According to Alive2, the target is more poisonous than source. ```ll define @src(i32 %a2, i32 %a3) #0 { %cvt2 = sitofp i32...
`InstCombine` transforms the following input `@src` into `@tgt`. According to Alive2, the target is more poisonous than source. Source is `@test_shrink_intrin_fabs_fast_double_src` in `llvm/test/Transforms/InstCombine/double-float-shrink-2.ll` ```ll declare double @llvm.fabs.f64(double) declare float @llvm.fabs.f32(float)...
As commented in `X86Subtarget.h`: ```hpp /// Use mfence if we have SSE2 or we're on x86-64 (even if we asked for /// no-sse2). There isn't any reason to disable it...

An average function written with intrinsics produces inaccurate values when optimized. It works with `-O0` but fails with all levels of optimization `-Os`, `-Oz`, `-O1`, `-O2` It also works when...
