Serge Guelton c0ebe773cd Portable Python script across Python version 
Using from __future__ import print_function it is possible to have a compatible behavior of `print(...)` across Python version.

Serge Guelton c5d97e3e35 Portable Python script across Python version 
Replace `xrange(...)` by either `range(...)` or `list(range(...))` depending on the context.

Python2 supports the two following equivalent construct

	raise ExceptionType, exception_value
and
	raise ExceptionType(exception_value)

Only the later is supported by Python3.

Daniel Dunbar 2e49bf2ceb Add utils/ABITest, my ABI test generation tool. 
- Mostly written as an entertaining exercise in enumerating large or
   (countably, naturally) infinite sets. But hey, its useful too!

 - Idea is to number all C-types so that the N-th type can quickly be
   computed, with a good deal of flexibility about what types to
   include, and taking some care so that the (N+1)-th type is
   interestingly different from the N-th type. For example, using the
   default generator, the 1,000,000-th function type is:
--
typedef _Complex int T0;
typedef char T1 __attribute__ ((vector_size (4)));
typedef int T2 __attribute__ ((vector_size (4)));
T2 fn1000000(T0 arg0, signed long long arg1, T1 arg2, T0 arg3);
--
   and the 1,000,001-th type is:
--
typedef _Complex char T0;
typedef _Complex char T2;
typedef struct T1 { T2 field0; T2 field1; T2 field2; } T1;
typedef struct T3 {  } T3;
unsigned short fn1000001(T0 arg0, T1 arg1, T3 arg2);
--

   Computing the 10^1600-th type takes a little less than 1s. :)
