Subject: sparse-llvm: void return type compiles to i8
Date: Sun, 19 Aug 2012 02:32:00 +0200	[thread overview]
Message-ID: <20120819003159.GB2880@debian.debian> (raw)

Hi!

A simple function like this will compile to the following llvm bitcode:

	/* C */
	void func(void) {
		return;
	}

	/* LLVM */
	define i8 @func() {
	L0:
	  ret void
	}

The return type of the function and the type in the return instruction
don't match.

I found this inconsistency by running LLVM's bitcode validation on the
bitcode produced by sparse-llvm.


Greetings,
Jonathan Neuschäfer
