Dan Gohman 8fed4ce0b8 Use find_first/find_next to iterate through all the set bits in a 
BitVector, instead of manually testing each bit.

Bill Wendling 9182147f17 Modify the intrinsics pattern to separate out the "return" types from the 
"parameter" types. An intrinsic can now return a multiple return values like
this:

  def add_with_overflow : Intrinsic<[llvm_i32_ty, llvm_i1_ty],
                                    [LLVMMatchType<0>, LLVMMatchType<0>]>;

Dan Gohman 6cd8ad06d6 Revert the part of r59145 that changed the comment about 
virtual registers possibly having multiple kills while still
being defined and killed in the same block. If LiveIntervals
is manually re-run after two-address lowering, it currently
does add extra kills to two-address instructions, but this
is considered a bug.

 2008-11-12 23:24:15 +00:00
Dan Gohman 88ba5f0b96 Move the code that inserts X87 FP_REG_KILL instructions from a 
special-purpose hook to a new pass. Also, add check to see if any
x87 virtual registers are used, to avoid doing any work in the
common case that no x87 code is needed.

Dan Gohman 0df957e09d Do the LiveVariables update before printing the instruction in 
the debug output, so that the updated liveness flags are
reflected in the debug output.

llvm-svn: 59147
 2008-11-12 17:15:19 +00:00
Dan Gohman 5efcb61337 Remove some debugging code made redundant by the change to do 
coalescing as a separate pass rather than inside of
LiveIntervalAnalysis.

 2008-11-12 17:09:23 +00:00
Dan Gohman da82aa3e0d Update VarInfo's comments to reflect the current code. LiveVar 
no longer records a unique defining instruction, and virtual
registers may have multiple kills while still being defined
and killed in the same block.

Mikhail Glushenkov a2909684b6 Check the return value of std::getenv. 
When constructing std::strings from C strings, we should check the input
value to be not NULL so that the std::string constructor does not
segfault.
Fixes #3047.

Duncan Sands 2907b0085c Simplify SplitVecRes_EXTRACT_SUBVECTOR. This means 
that it no longer handles non-power-of-two vectors.
However it previously only handled them sometimes,
depending on obscure numerical relationships between
the index and vector type.  For example, for a vector
of length 6, it would succeed if and only if the
index was an even multiple of 6.  I consider this
more confusing than useful.

Mikhail Glushenkov 1cb041242f Add a bit of lazy evaluation to PopulateCompilationGraph(). 
Only the tools that are mentioned in the compilation graph definition
are now inserted by PopulateCompilationGraph(). This should cut down
plugin loading time a little.

Owen Anderson fd395eb801 Don't walk into predecessors in which the vreg is not live when doing shrinkwrapping.

Dan Gohman e52e0897e2 In ScheduleDAGRRList::CopyAndMoveSuccessors, create the SUnit for the load 
before creating the SUnit for the operation that it was unfolded from. This
allows each SUnit to have all of its predecessor SUnits available at the time
it is created. I don't know yet if this will be absolutely required, but it
is a little tidier to do it this way.
