Mihai Popa [Thu, 22 Aug 2013 13:16:07 +0000 (13:16 +0000)]
Fix ARM vcvt encoding when the number of fractional bits is zero.

The instruction to convert between floating point and fixed point representations
takes an immediate operand for the number of fractional bits of the fixed point
value. ARMARM specifies that when that number of bits is zero, the assembler
should encode floating point/integer conversion instructions.

8 years agoTeach the SLP vectorizer the correct way to check for consecutive access
Chandler Carruth [Thu, 22 Aug 2013 12:45:17 +0000 (12:45 +0000)]
Teach the SLP vectorizer the correct way to check for consecutive access
using GEPs. Previously, it used a number of different heuristics for
analyzing the GEPs. Several of these were conservatively correct, but
failed to fall back to SCEV even when SCEV might have given a reasonable
answer. One was simply incorrect in how it was formulated.

There was good code already to recursively evaluate the constant offsets
in GEPs, look through pointer casts, etc. I gathered this into a form
code like the SLP code can use in a previous commit, which allows all of
this code to become quite simple.

There is some performance (compile time) concern here at first glance as
we're directly attempting to walk both pointers constant GEP chains.
However, a couple of thoughts:

1) The very common cases where there is a dynamic pointer, and a second
   pointer at a constant offset (usually a stride) from it, this code
   will actually not do any unnecessary work.

2) InstCombine and other passes work very hard to collapse constant
   GEPs, so it will be rare that we iterate here for a long time.

That said, if there remain performance problems here, there are some
obvious things that can improve the situation immensely. Doing
a vectorizer-pass-wide memoizer for each individual layer of pointer
values, their base values, and the constant offset is likely to be able
to completely remove redundant work and strictly limit the scaling of
the work to scrape these GEPs. Since this optimization was not done on
the prior version (which would still benefit from it), I've not done it
here. But if folks have benchmarks that slow down it should be straight
forward for them to add.

I've added a test case, but I'm not really confident of the amount of
testing done for different access patterns, strides, and pointer
manipulation.

combinations as not-legal-or-custom.  Although 32x32->{32,32}

so it needs to be implemented in terms of UMUL_LOHI.

However, not defining these patterns means that we don't convert
division by a constant into multiplication, so this patch fills
in the other cases.  The new i64 SMUL_LOHI sequence is simpler

with YAML, and for potential users of the MC CFG, by using it as an input.

There isn't much to the actual format, it is just a serialization of the
MCModule class. Of note:
  - Basic block references (pred/succ, ..) are represented by the BB's
    start address.
  - Just as in the MC CFG, instructions are MCInsts with a size.
  - Operands have a prefix representing the type (only register and
    immediate supported here).
  - Instruction opcodes are represented by their names; enum values aren't
    stable, enum names mostly are: usually, a change to a name would need
    lots of changes in the backend anyway.

Move registering the execution of a basic block to the beginning rather than the end.

There are situations which can affect the correctness (or at least expectation)
of the gcov output. For instance, if a call to __gcov_flush() occurs within a
block before the execution count is registered and then the program aborts in
some way, then that block will not be marked as executed. This is not normally
what the user expects.

If we move the code that's registering when a block is executed to the
beginning, we can catch these types of situations.
