I've also tested this patch on an aarch64 `postgres` build and found that it allows BOLT to run without --skip-funcs flags.
Without this patch the following error occurs:
```
llvm-bolt -o test.out.bolt postgres
BOLT-ERROR: unable to get new address corresponding to input address 0x2cb1b0 in function ExecInterpExpr/1(*2). Consider adding this function to --skip-funcs=...
```
The `ExecInterpExpr/1` function no longer need to be skipped when goto patch is applied.
