simple gcc coverage for kernel fuzzing

[hipphipphurax, 2015-10-13 06:33:01]

Hi,

I needed to change the types for two decleration for the my copy of gcc (git
02059be048e729d6ae25b948d2963959d833ae6f).

I am just trying to get it working and I am not an developer of gcc.

File fuzz.c (right):

https://codereview.appspot.com/267910043/diff/1/fuzz.c#newcode64
fuzz.c:64: gimple stmt, f;
I needed to change those two variables to pointers to get it compiling.

Acknowledged
Is your revision older or newer than 227353?
Eventually we need to upstream it and then all such problems will go away.

The last upstream commit contains this

git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@228707
138bc75d-0d04-0410-961f-82ee72b054a4

I read this as 228707 but not sure.

I've rebased this patch to gcc rev 228818.
And, yes, it required to add starts where you said.
thanks
