reference.  However, these are really only useful in GCC internal code
generation.  In inline asm the operand of the memory constraint is
typically just a register containing the address, so 'U' and 'X' make
no sense.

This patch quietly accepts 'U' and 'X' in inline asm patterns, but
otherwise does nothing.  If we ever unexpectedly see a non-register,
we'll assert and sort it out afterwards.

I've added a new test for these constraints; the test case should be
used for other asm-constraints changes down the road.

10 years ago[AVX512] Fix miscompile for unpack
Adam Nemet [Thu, 11 Sep 2014 16:51:10 +0000 (16:51 +0000)]
[AVX512] Fix miscompile for unpack

r189189 implemented AVX512 unpack by essentially performing a 256-bit unpack
between the low and the high 256 bits of src1 into the low part of the
destination and another unpack of the low and high 256 bits of src2 into the
high part of the destination.

I don't think that's how unpack works.  AVX512 unpack simply has more 128-bit
lanes but other than it works the same way as AVX.  So in each 128-bit lane,
we're always interleaving certain parts of both operands rather different
parts of one of the operands.

E.g. for this:
__v16sf a = { 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15 };
__v16sf b = { 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31 };
__v16sf c = __builtin_shufflevector(a, b, 0, 8, 1, 9, 4, 12, 5, 13, 16,
                  24, 17, 25, 20, 28, 21, 29);

we generated punpcklps (notice how the elements of a and b are not interleaved
in the shuffle).  In turn, c was set to this:

  0 16 1 17 4 20 5 21 8 24 9 25 12 28 13 29

Obviously this should have just returned the mask vector of the shuffle
vector.

I mostly reverted this change and made sure the original AVX code worked
for 512-bit vectors as well.

Also updated the tests because they matched the logic from the code.

R600/SI: Report offset in correct units for st64 DS instructions

Need to convert the 64 element offset into bytes, not just the element
size like the normal case instructions.

Noticed by inspection. This can't be hit now because
st64 instructions aren't emitted during instruction selection,
and the post-RA scheduler isn't enabled.

Add doInitialization/doFinalization to DataLayoutPass.

With this a DataLayoutPass can be reused for multiple modules.

Once we have doInitialization/doFinalization, it doesn't seem necessary to pass
a Module to the constructor.

Overall this change seems in line with the idea of making DataLayout a required
part of Module. With it the only way of having a DataLayout used is to add it
to the Module.

Make CallingConv::ID a plain unsigned instead of enum with a
