Chris Lattner d8d898dbd3 disable my previous inliner patch, it appears to be busting self-host.
llvm-svn: 102153
2010-04-23 00:41:03 +00:00
Chris Lattner 2eee5d3467 The inliner was choosing to not consider call sites
that appear in the SCC as a result of inlining as candidates
for inlining.  Change this so that it *does* consider call 
sites that change from being indirect to being direct as a
result of inlining.  This allows it to completely 
"devirtualize" the testcase.

Chris Lattner 4ba01ec869 refactor the interface to InlineFunction so that most of the in/out
arguments are handled with a new InlineFunctionInfo class.  This 
makes it easier to extend InlineFunction to return more info in the
future.

Chris Lattner e93846762a Fix rdar://7879828 - crash in CallGraph, a self host issue.
Arg promotion was deleting call graph nodes that still had references
from the 'indirect' CGN.  Like the inliner, it should only delete the
function if all references are gone.

Eric Christopher 7258dcd77f Revert 101465, it broke internal OpenGL testing.
Probably the best way to know that all getOperand() calls have been handled
is to replace that API instead of updating.

Chris Lattner 4422d31b84 introduce a new CallGraphSCC class, and pass it around
to CallGraphSCCPass's instead of passing around a
std::vector<CallGraphNode*>.  No functionality change,
but now we have a much tidier interface.

Gabor Greif f375520f7b reapply r101434
with a fix for self-hosting

rotate CallInst operands, i.e. move callee to the back
of the operand array

the motivation for this patch are laid out in my mail to llvm-commits:
more efficient access to operands and callee, faster callgraph-construction,
smaller compiler binary

Tobias Grosser de1a37b872 IPO needs ScalarOpts and InstCombine in its libs
The commit "Adding IPSCCP and Internalize passes to the C-bindings" introduced
new dependencies for IPO. Add these to the CMAKE build as otherwise the
BUILD_SHARED_LIBS=1 build fails.

Nick Lewycky 3cdae269f0 While DAE can't modify the function signature of an externally visible function,
it can check whether the visible direct callers are passing in parameters to
dead arguments and replace those with undef.

This reinstates r94322 with bugs fixed.

Dan Gohman 4bd755419f Revert the recent alignment changes. They're broken for -Os because,
in particular, they end up aligning strings at 16-byte boundaries, and
there's no way for GlobalOpt to check OptForSize.

Gabor Greif 5d5db5342b Introduce ImmutableCallSite, useful for contexts where no mutation
is necessary. Inherits from new templated baseclass CallSiteBase<>
which is highly customizable. Base CallSite on it too, in a configuration
that allows full mutation.
Adapt some call sites in analyses to employ ImmutableCallSite.

Eric Christopher 81c03447fc When we promote a load of an argument make sure to take the alignment
of the previous load - it's usually important.  For example, we don't want
to blindly turn an unaligned load into an aligned one.

Gabor Greif a2fbc0ae1b Finally land the InvokeInst operand reordering.
I have audited all getOperandNo calls now, fixing
hidden assumptions. CallSite related uglyness will
be eliminated successively.

Note this patch has a long and griveous history,
for all the back-and-forths have a look at
CallSite.h's log.

Gabor Greif 8335f9c0bf Recommit r80858 again (which has been backed out in r80871).
This time I did a self-hosted bootstrap on Linux x86-64,
with no problems. Let's see how darwin 64-bit self-hosting
goes. At the first sign of failure I'll back this out.

Maybe the valgrind bots give me a hint of what may be wrong
(it at all).

Jakob Stoklund Olesen b495cad7ca Try to keep the cached inliner costs around for a bit longer for big functions.
The Caller cost info would be reset everytime a callee was inlined. If the
caller has lots of calls and there is some mutual recursion going on, the
caller cost info could be calculated many times.

This patch reduces inliner runtime from 240s to 0.5s for a function with 20000
small function calls.

This is a more conservative version of r98089 that doesn't break the clang
test CodeGenCXX/temp-order.cpp. That test relies on rather extreme inlining
for constant folding.
