Devang Patel fa31d38aad Introduce DebugInfoProbe. This is used to monitor how llvm optimizer is treating debugging information. 
It generates output that lools like

8 times line number info lost by Scalar Replacement of Aggregates (SSAUp) 
1 times line number info lost by Simplify well-known library calls 
12 times variable info lost by Jump Threading

Eric Christopher 787ba0bf9b Make these options hidden to reduce the amount of text -help puts on the 
command line, they'll still be seen with -help-hidden.

Justin Holewinski 0cfa737f27 ptx: Fix calling convention printing in AsmWriter.cpp 
This allows LLVM IR using ptx_kernel or ptx_device calling
conventions to be properly printed when emitted in text form.

Nick Lewycky 92db8e8e39 ConstantInt has some getters which return ConstantInt's or ConstantVector's of 
the value splatted into every element. Extend this to getTrue and getFalse which
by providing new overloads that take Types that are either i1 or <N x i1>. Use
it in InstCombine to add vector support to some code, fixing PR8469!

Rafael Espindola 1e49a6d9bc Add a special streamer to libLTO that just records symbols definitions and 
uses.

The result produced by the streamer is used to give the linker more accurate
information and to add to llvm.compiler.used. The second improvement removes
the need for the user to add __attribute__((used)) to functions only used in
inline asm. The first one lets us build firefox with LTO on Darwin :-)

Chris Lattner 34442e6ebf revert my ConstantVector patch, it seems to have made the llvm-gcc 
builders unhappy.

Nadav Rotem 27b848afb0 Fix a regression from r125393; 
It caused a crash in MultiSource/Benchmarks/Bullet.
Opt hit an assertion with "opt -std-compile-opts" because
Constant::getAllOnesValue doesn't know how to handle floats.

This patch added a test to reproduce the problem and a check that the
destination vector is of integer type.

Thank you Benjamin!

Chris Lattner e9b4ad7391 switch the constantexpr, target folder, and IRBuilder interfaces 
for NSW/NUW binops to follow the pattern of exact binops.  This
allows someone to use Builder.CreateAdd(x, y, "tmp", MaybeNUW);

Factor some code better.

 2011-02-07 16:40:21 +00:00
Chris Lattner 35315d065b enhance vmcore to know that udiv's can be exact, and add a trivial 
instcombine xform to exercise this.

Nothing forms exact udivs yet though.  This is progress on PR8862

Nick Lewycky 97a2895e73 Add the select optimization recently added to instcombine to constant folding. 
This is the one where one of the branches of the select is another select on
the same condition.

Nick Lewycky 39b12c059d Add a constant folding of casts from zero to zero. Fixes PR9011! 
While here, I'd like to complain about how vector is not an aggregate type
according to llvm::Type::isAggregateType(), but they're listed under aggregate
types in the LangRef and zero vectors are stored as ConstantAggregateZero.

Jay Foad 1d4a8fe156 Remove casts between Value** and Constant**, which won't work if a 
static_cast from Constant* to Value* has to adjust the "this" pointer.
This is groundwork for PR889.

Duncan Sands 7f60dc1eb0 Move some shift transforms out of instcombine and into InstructionSimplify. 
While there, I noticed that the transform "undef >>a X -> undef" was wrong.
For example if X is 2 then the top two bits must be equal, so the result can
not be anything.  I fixed this in the constant folder as well.  Also, I made
the transform for "X << undef" stronger: it now folds to undef always, even
though X might be zero.  This is in accordance with the LangRef, but I must
admit that it is fairly aggressive.  Also, I added "i32 X << 32 -> undef"
following the LangRef and the constant folder, likewise fairly aggressive.
