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
call void @llvm.dbg.declare(metadata float* %x, metadata !649, metadata
!494), !dbg !651
%1 = load float, float* %x, !dbg !652
%2 =
