Jakob Stoklund Olesen e6aed139f0 Write llvm-tblgen backends as functions instead of sub-classes. 
The TableGenBackend base class doesn't do much, and will be removed
completely soon.

Patch by Sean Silva!

Chris Lattner 3cb6f83ebb switch AttrListPtr::get to take an ArrayRef, simplifying a lot of clients.

Chris Lattner ff9e08baf9 rdar://11542750 - llvm.trap should be marked no return.

Chris Lattner 144b619684 Reimplement the intrinsic verifier to use the same table as Intrinsic::getDefinition, 
making it stronger and more sane.

Delete the code from tblgen that produced the old code.

Besides being a path forward in intrinsic sanity, this also eliminates a bunch of
machine generated code that was compiled into Function.o

 2012-05-27 19:37:05 +00:00
Chris Lattner f39c278384 move some code around so that Verifier.cpp can get access to the intrinsic info table. 
llvm-svn: 157540
 2012-05-27 18:28:35 +00:00
Chris Lattner c464416107 enhance the intrinsic info table to encode what *kind* of Any argument 
it is (at the cost of 45 bytes of extra table space) so that the verifier can
start using it.

llvm-svn: 157536

Chris Lattner c5a825bb79 rearrange some code, no functionality change.

Chris Lattner 4f18aa8f04 small refinement to r157218 to save a tiny amount of table size in the common 
case.

Pete Cooper 243efd7ac3 Added address space qualifier to intrinsic PointerType arguments. 
llvm-svn: 157218
 2012-05-21 23:21:28 +00:00
Chris Lattner a3b0f52a72 enhance the intrinsic info stuff to emit encodings that don't fit in 32-bits into a 
separate side table, using the handy SequenceToOffsetTable class.  This encodes all
these weird things into another 256 bytes, allowing all intrinsics to be encoded this way.

llvm-svn: 156995
 2012-05-17 15:55:41 +00:00
Chris Lattner 3e34a7b93d finish encoding all of the interesting details of intrinsics. Now intrinsics 
are only rejected because they can't be encoded into a 32-bit unit, not because
they contain an unencodable feature.

llvm-svn: 156978
 2012-05-17 05:03:24 +00:00
Chris Lattner 827b253c63 strengthen the intrinsic descriptor stuff to be able to handle sin, cos and other 
intrinsics that use passed-in arguments.

llvm-svn: 156977
 2012-05-17 04:30:58 +00:00
Chris Lattner 786edd228a simplify code generated by tblgen that is not necessary since we dropped 
compatibility with LLVM 2.x bitcode files.

 2012-05-17 03:38:19 +00:00
Chris Lattner 7f0e7bae25 Significantly reduce the compiled size of Functions.cpp by turning a big blob of tblgen 
generated code (for Intrinsic::getType) into a table.  This handles common cases right now,
but I plan to extend it to handle all cases and merge in type verification logic as well
in follow-on patches.

Chris Lattner d785d060f9 have tblgen emit cast<> instead of dyn_cast<> when we know it must succeed.

Douglas Gregor 12c1cd33f4 Move llvm-tblgen's StringMatcher into the TableGen library so it can 
be used by clang-tblgen.

much cleaner.

John McCall 375dcc9ec9 Change how tblgen generates attributes for intrinsics to use a single 
switch.  With this newfound organization, teach tblgen how not to give
all intrinsics the 'nounwind' attribute.  Introduce a new intrinsic,
llvm.eh.resume, which does not have this attribute.  Documentation and uses
to follow.

Duncan Sands 78376ad7e1 Partially address a README by having functionattrs consider calls to 
memcpy, memset and other intrinsics that only access their arguments
to be readnone if the intrinsic's arguments all point to local memory.
This improves the testcase in the README to readonly, but it could in
theory be made readnone, however this would involve more sophisticated
analysis that looks through the memcpy.

Owen Anderson 9f94459d24 Split EVT into MVT and EVT, the former representing _just_ a primitive type, while 
the latter is capable of representing either a primitive or an extended type.

Bob Wilson 1024634df7 Fix the verifier to handle intrinsics with LLVMMatchType parameters, where 
the return type of the intrinsic is not overloaded, i.e., where the type
being matched is some other parameter.  The argument to LLVMMatchType is
an index into the list of overloaded types (ignoring the fixed types),
but VerifyIntrinsicPrototype is expecting its arguments for LLVMMatchType
parameters to be indices into the combined list of _all_ return values and
parameters, not just the overloaded ones.

This patch changes TableGen to keep track for each overloaded type of the
corresponding index into the list of return values and parameters.  It
then generates the values expected by VerifyIntrinsicPrototype.
