Bug ID: 49693
Summary: GOT references generated for code that requests static
relocation model
Product: libraries
Version: trunk
Hardware: PC
OS: All
Status: NEW
Severity: normal
Priority: P
Component: Common Code Generator Code

; RUN: llc --relocation-model=static -mtriple=aarch64-none < %s
; RUN: llc --relocation-model=static -mtriple=x86_64-none < %s
define void @peach() unnamed_addr {
start:
br label %bb1
bb1: ; preds = %bb1, %start
%0 = load volatile i8, i8* bitcast (void ()* @banana to i8*), align 1
br label %bb1
}
declare void @banana() unnamed_addr
The following example generates GOT references in LLVM 12, but did not do so in
LLVM 11.
If the `@banana` is marked as `dso_local`, then a local reference is generated,
however my understanding is that the `dso_local` annotation is a hint that the
compiler is allowed to generate direct references and not that its absence
requires it to produce GOT references.
