Chris Lattner f59e4e3452 enhance the logic for looking through tailcalls to look through transparent casts
in multiple-return value scenarios, like what happens on X86-64 when returning
small structs.

Chris Lattner 5b0d946537 enhance getNoopInput to know about vector<->vector bitcasts of legal
types, as well as int<->ptr casts.  This allows us to tailcall functions
with some trivial casts between the call and return (i.e. because the
return types disagree).

Chris Lattner f186df0d3e it's pointed out that R11 can be used for magic things, and doing things just for 64-bit registers is silly. Just optimize 3 more.

Chris Lattner 5aaabbfe62 Extend the (abi-irrelevant) return convention to be able to return more than two values in
integer registers.  This is already supported by the fastcc convention, but it doesn't
hurt to support it in the standard conventions as well.

In cases where we can cheat at the calling convention, this allows us to avoid returning
things through memory in more cases.

Chris Lattner 55dc5c77a3 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

Chris Lattner c32cef6aa1 These tests used intrinsics with the wrong prototype. They weren't caught because
the old verifier just checked that something "was a pointer", but not that the pointee
was correct.

Chris Lattner b4654c1c49 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.

Chris Lattner 387c9dcdda 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.

Chris Lattner d7cf5eb021 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.

Chris Lattner a98aa6ad1e 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.

2) bugpoint driver accounts opt plugins, but does not list them in the
final output command.

Chris Lattner 4871701437 No actual functional change here, just some clarifications:
Clarify that contributors are agreeing to license their code under the 
license corresponding to the subproject that they are contributing to,
as requested by a potential contributor.

Also, as a drive-by, update the llvm-gcc/GPL section to mention dragonegg
and say that GPL code is all in its own repo's.

Chris Lattner 18c7f80b3e reapply the patches reverted in r149470 that reenable ConstantDataArray,
but with a critical fix to the SelectionDAG code that optimizes copies
from strings into immediate stores: the previous code was stopping reading
string data at the first nul.  Address this by adding a new argument to
llvm::getConstantStringInfo, preserving the behavior before the patch.

2012-01-31 04:43:11 +00:00
Chris Lattner 3ef9cfef13 Change ConstantArray::get to form a ConstantDataArray when possible,
kicking in the big win of ConstantDataArray.  As part of this, change
the implementation of GetConstantStringInfo in ValueTracking to work
with ConstantDataArray (and not ConstantArray) making it dramatically,
amazingly, more efficient in the process and renaming it to 
getConstantStringInfo.

This keeps around a GetConstantStringInfo entrypoint that (grossly)
forwards to getConstantStringInfo and constructs the std::string 
required, but existing clients should move over to 
getConstantStringInfo instead.

Chris Lattner 6e3abaa77f Ok, break down and add some cast<>'ing helper methods to the Type class
to reduce the number of cast<>'s we have.  This allows someone to use
things like Ty->getVectorNumElements() instead of 
cast<VectorType>(Ty)->getNumElements() when you know that a type is a
vector.

It would be a great general cleanup to move the codebase to use these,
I will do so in the code I'm touching.
