error: aborting due to previous error
Fail on multiple declarations of `main`. Previously, when inserting the entry function, we only checked for duplicate _definitions_ of `main`. However, it's possible to cause problems even only having a duplicate _declaration_. For example, shadowing `main` using an extern block isn't caught by the current check, and causes an assertion failure down the line in in LLVM code. 2020-02-22 09:43:47 -06:00			error: entry symbol `main` declared multiple times
