Jim Grosbach 1752ffbfe5 Tidy up. No need for a Twine here, as it's just constants.

Jim Grosbach 3ae48a6236 TableGen use PrintWarning rather than fprintf(stderr,...) for warnings. 
That way we get source line number information from the diagnostics.

Jakob Stoklund Olesen dd8fbf572e Delete CodeInit and CodeRecTy from TableGen. 
The code type was always identical to a string anyway. Now it is simply
a synonym. The code literal syntax [{...}] is still valid.

Jakob Stoklund Olesen d9444d455e Ban rematerializable instructions with side effects. 
TableGen infers unmodeled side effects on instructions without a
pattern.  Fix some instruction definitions where that was overlooked.

Also raise an error if a rematerializable instruction has unmodeled side
effects. That doen't make any sense.

Peter Collingbourne 84c287e33c Move TableGen's parser and entry point into a library 
This is the first step towards splitting LLVM and Clang's tblgen executables.

David Greene e32ebf220a [AVX] Create Inits Via Factory Method 
Replace uses of new *Init with *Init::get.  This hides the allocation
implementation so that we can unique Inits in various ways.

David Greene 1aa0e3e118 [AVX] Constify Inits 
Make references to Inits const everywhere.  This is the final step
before making them unique.

Jakob Stoklund Olesen abcfdcea5c Intern all RecTy subclass instances to avoid duplicates. 
Make all of the RecTy constructors private, and use get() factory
methods instead. Return singleton instances when it makes sense.

ListTy instance pointers are stored in the element RecTy instance.

BitsRecTy instance pointers, one per length, are stored in a static vector.

Also unique DefInit instances. A Record has a unique DefInit which
has a unique RecordRecTy instance.

This saves some 200k-300k RecTy allocations when parsing ARM.td. It
reduces TableGen's heap usage by almost 50%.

David Greene af973b4f36 [AVX] Make Inits Foldable 
Manage Inits in a FoldingSet.  This provides several benefits:

- Memory for Inits is properly managed

- Duplicate Inits are folded into Flyweights, saving memory

- It enforces const-correctness, protecting against certain classes
  of bugs

The above benefits allow Inits to be used in more contexts, which in
turn provides more dynamism to TableGen.  This enhanced capability
will be used by the AVX code generator to a fold common patterns
together.

Jim Grosbach fdc02c1b0d Typo.

Owen Anderson a84be6c96b Add support for alternative register names, useful for instructions whose operands are logically equivalent to existing registers, but happen to be printed specially. For example, an instruciton that prints d0[0] instead of s0.

Jim Grosbach 797cff0504 Consolidate some TableGen diagnostic helper functions. 
TableGen had diagnostic printers sprinkled about in a few places. Pull them
together into a single location in Error.cpp.

Chris Lattner 0d7a5a7daa since the VT is fixed for a ImmLeaf, there is no reason to expose it to the matching code.

 2011-04-17 22:17:27 +00:00
Chris Lattner 2ff8c1a25f now that predicates have a decent abstraction layer on them, introduce a new 
kind of predicate: one that is specific to imm nodes.  The predicate function
specified here just checks an int64_t directly instead of messing around with
SDNode's.  The virtue of this is that it means that fastisel and other things
can reason about these predicates.

Chris Lattner 514e292b72 Rework our internal representation of node predicates to expose more 
structure and fix some fixmes.  We now have a TreePredicateFn class
that handles all of the decoding of these things.  This is an internal
cleanup that has no impact on the code generated by tblgen.

Evan Cheng 880e299dcd - Add "Bitcast" target instruction property for instructions which perform 
nothing more than a bitcast.
- Teach tablegen to automatically infer "Bitcast" property.
