Dan Gohman 797a1dbb1c To create a copy of a SmallVector with an element removed from the 
middle, copy the elements in two groups, rather than copying all the
elements and then doing an erase on the middle of the result. These
are SmallVectors, so we shouldn't expect to hit dynamic allocation
in the common case.

Dan Gohman 89fdbaf99a Instead of having CollectSubexpr's categorize operands as interesting or 
uninteresting, just put all the operands on one list and make
GenerateReassociations make the decision about what's interesting.
This is simpler, and it avoids an extra ScalarEvolution::getAddExpr call.

llvm-svn: 111133
 2010-08-16 15:50:00 +00:00
Dan Gohman 9b7632df26 Put add operands in ScalarEvolution-canonical order, when convenient. 
This isn't necessary, because ScalarEvolution sorts them anyway,
but it's tidier this way.

 2010-08-16 15:39:27 +00:00
Dan Gohman 9c9ce53b29 Add hooks to FoldingSetTrait to allow specializations to provide 
implementations of equality comparison and hash computation. This
can be used to optimize node lookup by avoiding creating lots of
temporary ID values just for hashing and comparison purposes.

Dan Gohman 6e964c7fb4 Avoid #include <ScalarEvolution.h> in LoopSimplify.cpp, which doesn't 
actually use ScalarEvolution.

Dan Gohman 250b754428 Instead, teach SimplifyCFG to trim non-address-taken blocks from 
indirectbr destination lists.

Dan Gohman fb83b043eb Revert r111058, the lint check for indirectbr successors that aren't 
address-taken. This can occur normally, if the code which took the
address got DCEd.

Eric Christopher 54194bd127 Rework how the non-sse2 memory barrier is lowered so that the 
encoding is correct for the built-in assembler.

Based on a patch from Chris.

Dan Gohman aa445c0751 LoopSimplify shouldn't split loop backedges that use indirectbr. PR7867.

 2010-08-14 00:43:09 +00:00
Dan Gohman 4a63fad976 Teach SimplifyCFG how to simplify indirectbr instructions. 
- Eliminate redundant successors.
 - Convert an indirectbr with one successor into a direct branch.

Also, generalize SimplifyCFG to be able to be run on a function entry block.
It knows quite a few simplifications which are applicable to the entry
block, and it only needs a few checks to avoid trouble with the entry block.

Jim Grosbach a030fa5297 Add a local stack object block allocation pass. This is still an 
experimental pass that allocates locals relative to one another before
register allocation and then assigns them to actual stack slots as a block
later in PEI. This will eventually allow targets with limited index offset
range to allocate additional base registers (not just FP and SP) to
more efficiently reference locals, as well as handle situations where
locals cannot be referenced via SP or FP at all (dynamic stack realignment
together with variable sized objects, for example). It's currently
incomplete and almost certainly buggy. Work in progress.

Disabled by default and gated via the -enable-local-stack-alloc command
line option.

had its address taken.

Jakob Stoklund Olesen 27e1f26534 Clean up the Spiller.h interface. 
The earliestStart argument is entirely specific to linear scan allocation, and
can be easily calculated by RegAllocLinearScan.

Replace std::vector with SmallVector.

Dan Gohman 0c436ab356 Various optimizations. Don't compare two loops' depths 
when they are the same loop. Don't compare two instructions'
loop depths when they are in the same block.

Jakob Stoklund Olesen d1191ee43c Implement splitting inside a single block. 
When a live range is contained a single block, we can split it around
instruction clusters. The current approach is very primitive, splitting before
and after the largest gap between uses.

Dan Gohman 081ffcd00b Fix LSR's ExtractImmediate and ExtractSymbol to avoid calling 
ScalarEvolution::getAddExpr, which can be pretty expensive, when nothing
has changed, which is pretty common.

Dan Gohman cf32f2bde1 When creating a symmetric SCEV with a constant operand, put 
the constant operand on the left, as that's where ScalarEvolution
will end up canonicalizing to.

Dan Gohman ec0120a123 An add recurrence is loop-invariant in any loop inside of its

of the add recurrence's operands.
