Daniel Dunbar b4e80a5b19 ABITestGen: Add v2i16 and v16f32 as default vector types to generate. 
llvm-svn: 65810

Daniel Dunbar 3ebd531b2c ABITestGen: Use explicit list of vector types instead of just a list 
of sizes. Turns out we don't care very much about vector types that
don't map to the hardware.

Daniel Dunbar 79d10a2f43 ABITest: Add some checking of values for return types; useful for 
catching internal consistency problems (esp. w/ reference compiler).

Daniel Dunbar 676fdd81d5 ABITest: Fix test value generation for unions.

Daniel Dunbar 7bb8dfae53 Use xcc (instead of clang directly).

Daniel Dunbar 6ec8a4d9e3 ABITest: Support --test-layout option for generating 
size/alignment/offsetof based tests of types instead of calling
convention tests.

Daniel Dunbar ed4361ecbb Add simple make based harness for running ABI tests.

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. :)
