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

10 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.

  - nested lambdas
  - conversion operator for captureless lambdas
  - ensuring all visitors are generic lambda aware

  int num_params =  O(O, 5, 3, "abc", 3.14, 'a');

Please see attached tests for more examples.

Some implementation notes:

  - Add a new Declarator context => LambdaExprParameterContext to
    clang::Declarator to allow the use of 'auto' in declaring generic
    lambda parameters

  - Augment AutoType's constructor (similar to how variadic
    template-type-parameters ala TemplateTypeParmDecl are implemented) to
    accept an IsParameterPack to encode a generic lambda parameter pack.

  - Add various helpers to CXXRecordDecl to facilitate identifying
    and querying a closure class

  - LambdaScopeInfo (which maintains the current lambda's Sema state)
    was augmented to house the current depth of the template being
    parsed (id est the Parser calls Sema::RecordParsingTemplateParameterDepth)
    so that Sema::ActOnLambdaAutoParameter may use it to create the
    appropriate list of corresponding TemplateTypeParmDecl for each
    auto parameter identified within the generic lambda (also stored
    within the current LambdaScopeInfo).  Additionally,
    a TemplateParameterList data-member was added to hold the invented
    TemplateParameterList AST node which will be much more useful
    once we teach TreeTransform how to transform generic lambdas.

  - SemaLambda.h was added to hold some common lambda utility
    functions (this file is likely to grow ...)

  - Teach Sema::ActOnStartOfFunctionDef to check whether it
    is being called to instantiate a generic lambda's call
    operator, and if so, push an appropriately prepared
    LambdaScopeInfo object on the stack.

  - Teach Sema::ActOnStartOfLambdaDefinition to set the
    return type of a lambda without a trailing return type
    to 'auto' in C++1y mode, and teach the return type
    deduction machinery in SemaStmt.cpp to process either
    C++11 and C++14 lambda's correctly depending on the flag.

  - various tests were added - but much more will be needed.

A greatful thanks to all reviewers including Eli Friedman,
James Dennett and the ever illuminating Richard Smith.  And
yet I am certain that I have allowed unidentified bugs to creep in;

Rafael Espindola [Wed, 21 Aug 2013 21:59:03 +0000 (21:59 +0000)]
Move -mfpmath handling to -cc1 and implement it for x86.

The original idea was to implement it all on the driver, but to do that the
driver needs to know the sse level and to do that it has to know the default
features of a cpu.

Benjamin Kramer pointed out that if one day we decide to implement support for
' __attribute__ ((__target__ ("arch=core2")))', then the frontend needs to
keep its knowledge of default features of a cpu.

To avoid duplicating which part of clang handles default cpu features,
it is probably better to handle -mfpmath in the frontend.

For ARM this patch is just a small improvement. Instead of a cpu list, we
check if neon is enabled, which allows us to reject things like

-mcpu=cortex-a9 -mfpu=vfp -mfpmath=neon

For X86, since LLVM doesn't support an independent ssefp feature, we just
make sure the selected -mfpmath matches the sse level.
