URL: https://github.com/llvm/llvm-project/commit/cfc002714a208bdbc51fade56141a38fbba26e24 DIFF: https://github.com/llvm/llvm-project/commit/cfc002714a208bdbc51fade56141a38fbba26e24.diff LOG: [AVR] Support aliases in non-zero address space This fixes code like the following on AVR: void foo(void) { } void bar(void) __attribute__((alias("foo"))); Code like this is present in compiler-rt, which I'm trying to build.
