Fixing the ilp32 issue that Christophe found.
The existing testcase uses `long` to represent a 64 bit integer.
This breaks when compiled using the `-mabi=ilp32` flag.
We switch the use of int/long for int32_t/int64_t to avoid this problem
and show the requirement of a widening operation more clearly.
Normally we try to avoid pulling more headers than we need in the testsuite.
Have you seen this construct:
typedef unsigned __attribute__((mode(DI))) uint64_t;
It can be a good way to ensure you have the right type for the patterns you
Thanks! No I hadn't seen that construct before.
Have attached a patch using that construct.
I've committed this on behalf of Matthew as r263946 with an updated ChangeLog entry
