Bug ID: 52029
Summary: Aarch64-Darwin Large Code Model is not implemented
correctly. Memory allocator crash
Product: new-bugs
Version: 12.0
Hardware: Macintosh
OS: MacOS X
Status: NEW
Severity: enhancement
Priority: P
Component: new bugs

In https://github.com/JuliaLang/julia/issues/41440#issuecomment-932016347 and
https://github.com/JuliaLang/julia/issues/42295 we've noticed a recurring issue
related to the large code model for the new Apple Silicon chips.
The issue is that the Orc JIT will crash if the memory allocator does not
allocate sections within 4GB of each other (which the default allocator does
not).
Possible relevant lines of code:
https://github.com/llvm/llvm-project/blob/6f7483b1ece4747f2aafe4baa05fc07e7dc9ed9d/llvm/lib/Target/AArch64/AArch64ISelLowering.cpp#L7687-L7689
