Rafael Espindola 36b718fc74 Avoid a Symbol -> Name -> Symbol conversion. 
Before this we were producing a TargetExternalSymbol from a MCSymbol.
That meant extracting the symbol name and fetching the symbol again
down the pipeline.

This patch adds a DAG.getMCSymbol that lets the MCSymbol pass unchanged on the
DAG.

Doing so removes the need for MO_NOPREFIX and fixes the root cause of pr23900,
allowing r240130 to be committed again.

Benjamin Kramer f5e2fc474d Replace push_back(Constructor(foo)) with emplace_back(foo) for non-trivial types 
If the type isn't trivially moveable emplace can skip a potentially
expensive move. It also saves a couple of characters.


Call sites were found with the ASTMatcher + some semi-automated cleanup.

memberCallExpr(
    argumentCountIs(1), callee(methodDecl(hasName("push_back"))),
    on(hasType(recordDecl(has(namedDecl(hasName("emplace_back")))))),
    hasArgument(0, bindTemporaryExpr(
                       hasType(recordDecl(hasNonTrivialDestructor())),
                       has(constructExpr()))),
    unless(isInTemplateInstantiation()))

No functional change intended.

James Y Knight e452e27129 Fix tablegen's PrintFatalError function to run registered file 
cleanups.

Also, change code in tablegen which printed a message and then called
"exit(1)" to use PrintFatalError, instead.

This fixes instances where an empty output file was left behind after
a failed tablegen invocation, which would confuse subsequent ninja
runs into not attempting to rebuild.

Craig Topper 1bf3d1f5dd [TableGen] Use 'isa' to identify UnsetInits rather than comparing with the singleton object created by UnsetInit::get(). Makes it more consistent with the other types.

Craig Topper 3a8eb896c9 [Tablegen] Attempt to add support for patterns containing nodes with multiple results. 
This is needed for AVX512 masked scatter/gather support.

The R600 change is necessary to remove a hack that was working around the lack of multiple results.

Craig Topper 35b3dbc4a3 Revert "[TableGen] Implement at least some support for multiple explicit results in an instruction pattern. No functional change to existing patterns."

Craig Topper 5edbf1ccaf [TableGen] Implement at least some support for multiple explicit results in an instruction pattern. No functional change to existing patterns. 
This should help with the AVX512 masked gather changes Elena is working on. This patch is derived from some of the changes Elena made to tablegen, but modified by me to support arbitrary number of results.

Craig Topper 0be3458006 [TableGen] Add support constraining a vector type in a pattern to have a specific element type and for constraining a vector type to have the same number of elements as another vector type. This is useful for AVX512 mask operations so we relate the mask type to the type of the other arguments.

Craig Topper 483a3000f5 [Tablegen] Use correct result number variables with the pattern nodes they go with when handling SDTCisSameAs. No functional change as they are always both 0 unless you try to define a multi result type profile that uses SDTCisSame on one of the other results.

Elena Demikhovsky 0995479e67 Reverted 230471 - gather scatter handling in table gen. 
llvm-svn: 230892
 2015-03-01 08:23:41 +00:00
Elena Demikhovsky 56eadcf5ce AVX-512: Gather and Scatter patterns 
Gather and scatter instructions additionally write to one of the source operands - mask register.
In this case Gather has 2 destination values - the loaded value and the mask.
Till now we did not support code gen pattern for gather - the instruction was generated from 
intrinsic only and machine node was hardcoded.
When we introduce the masked_gather node, we need to select instruction automatically,
in the standard way.
I added a flag "hasTwoExplicitDefs" that allows to handle 2 destination operands.

(Some code in the X86InstrFragmentsSIMD.td is commented out, just to split one big
patch in many small patches)
