LLVM behavior different depending on function symbol name
Greetings,
I have a Zig implementation of ceil which is emitted into LLVM IR like this:
; Function Attrs: nobuiltin nounwind
define internal fastcc float @ceil(float) unnamed_addr #3 !dbg !644 {
Entry:
%x = alloca float, align 4
store float %0, float* %x
