[X86] Create X86InstrFMA3Group objects fully in a static table instead of on the heap. NFCI

Previously we heap allocated the X86InstrFMA3Group objects which were created by passing them small register/memory opcode arrays that existed as individual static tables.

Rather than a bunch of small static arrays we now have one large static table of X86InstrFMA3Group objects. Rather than storing a pointer to the opcode arrays in the X86InstrFMA3Group object, we now store have a register and memory array as part of the object. If a group doesn't have memory or register opcodes, the array entries will be 0.

This greatly simplifies the destruction of the X86InstrFMA3Info object. We no longer need to delete the X86InstrFMA3Group objects as we destruct the DenseMap. And we don't need to keep track of which ones we already deleted.

This reduces the llc binary size on my local machine by ~50k. I can only assume that's really due to the fact that we had something like 512 small static arrays that we passed to the init functions either one at a time or in pairs. So there were between 256 and 512 distinct calls to the init functions in the initOnceImpl method.

[TableGen] Prevent double flattening of InstAlias asm strings in the asm matcher emitter.

Unlike CodeGenInstruction, CodeGenInstAlias was flatting asm strings in its constructor. For instructions it was the users responsibility to flatten the string.

AsmMatcherEmitter didn't know this and treated them the same. This caused double flattening of InstAliases. This is mostly harmless unless the desired assembly string contains curly braces. The second flattening wouldn't know to ignore these and would remove the curly braces. And for variant 1 it would remove the contents of them as well.

To mitigate this, this patch makes removes the flattening from the CodeGenIntAlias constructor and modifies AsmWriterEmitter to account for the flattening not having been done.

6 years agoAvoid needing to walk out legalization tables. NFCI.
Nirav Dave [Sat, 16 Jun 2018 02:51:29 +0000 (02:51 +0000)]
Avoid needing to walk out legalization tables. NFCI.

Relanding after fixing expensive check from modifying tables.

To avoid redundant work, during DAG legalization we keep tables
mapping pre-legalized SDValues to post-legalized SDValues and a
SDValue-to-SDValue map to enable fast node replacements. However, as
the keys are nodes which may be reused it is possible that an entry in
a table refers to a now deleted node N (that should have been renamed
by the value replacement map) while a new node N' exists. If N' is
then replaced that entry would be wrong. Previously we avoided this by
when potentially violating this property, walking every table and
updating all node pointers. This is very expensive but hopefully rare
occurance.

This patch assigns each instance of a SDValue used in legalization a
unique id and uses these ids in the legalization tables. This avoids
any such aliasing issue, avoiding the full table search and allowing
more aggressive incremental table pruning.

In some cases this is a 1000x speedup to compilation.

[globalisel][tablegen] Add support for C++ predicates on PatFrags and use it to support BFC on ARM.

So far, we've only handled special cases of PatFrag like ImmLeaf. This patch
adds support for the remaining cases using similar mechanisms.

Like most C++ code from SelectionDAG, GISel and DAGISel expect to operate on
different types and representations and as such the code is not compatible
between the two. It's therefore necessary to add an alternative implementation
in the GISelPredicateCode field.

The target test for this feature could easily be done with IntImmLeaf and this
would save on a little boilerplate. The reason I've chosen to implement this
using PatFrag.GISelPredicateCode and not IntImmLeaf is because I was unable to
find a rule that was blocked solely by lack of support for PatFrag predicates. I
found that the ones I investigated as being likely candidates for the test
were further blocked by other things.

there are cases where it does not really add anything

6 years agoRe-apply "[DebugInfo] Check size of variable in ConvertDebugDeclareToDebugValue"

Re-apply "[DebugInfo] Check size of variable in ConvertDebugDeclareToDebugValue"

This is r334704 (which was reverted in r334732) with a fix for
types like x86_fp80. We need to use getTypeAllocSizeInBits and
not getTypeStoreSizeInBits to avoid dropping debug info for
such types.

Original commit msg:
> Summary:
> Do not convert a DbgDeclare to DbgValue if the store
> instruction only refer to a fragment of the variable
> described by the DbgDeclare.
>
> Problem was seen when for example having an alloca for an
> array or struct, and there were stores to individual elements.
> In the past we inserted a DbgValue intrinsics for each store,
> just as if the store wrote the whole variable.
>
> When handling store instructions we insert a DbgValue that
> indicates that the variable is "undefined", as we do not know
> which part of the variable that is updated by the store.
>
> When ConvertDebugDeclareToDebugValue is used with a load/phi
> instruction we assert that the referenced value is large enough
> to cover the whole variable. Afaict this should be true for all
> scenarios where those methods are used on trunk. If the assert
> blows in the future I guess we could simply skip to insert a
> dbg.value instruction.
>
> In the future I think we should examine which part of the variable
> that is accessed, and add a DbgValue instrinsic with an appropriate
> DW_OP_LLVM_fragment expression.
