Duncan Sands 94580c7522 Test that a call to a trampoline is turned into a call to 
the underlying nested function.

 2007-09-11 15:07:50 +00:00
Duncan Sands d781335d39 Two ParamAttrsVectors which differ by a permutation 
of their elements do not yield the same ParamAttrsList,
though they should.  On the other hand, everyone seems
to pass such vectors with elements ordered by increasing
index, so rather than sorting the elements simply assert
that the elements are ordered in this way.

Chris Lattner 33a7f51412 1. Don't call Value::getName(), which is slow. 
2. Lower calls to fabs and friends to FABS nodes etc unless the function has
   internal linkage.  Before we wouldn't lower if it had a definition, which
   is incorrect.  This allows us to compile:

define double @fabs(double %f) {
        %tmp2 = tail call double @fabs( double %f )
        ret double %tmp2
}

into:

_fabs:

Duncan Sands 6820abe101 Testcases for PR1628. 
llvm-svn: 41719
 2007-09-05 11:53:04 +00:00
Duncan Sands 3c1b7fc056 Fix PR1628. When exception handling is turned on, 
labels are generated bracketing each call (not just
invokes).  This is used to generate entries in
the exception table required by the C++ personality.
However it gets in the way of tail-merging.  This
patch solves the problem by no longer placing labels
around ordinary calls.  Instead we generate entries
in the exception table that cover every instruction
in the function that wasn't covered by an invoke
range (the range given by the labels around the invoke).
As an optimization, such entries are only generated for
parts of the function that contain a call, since for
the moment those are the only instructions that can
throw an exception [1].  As a happy consequence, we
now get a smaller exception table, since the same
region can cover many calls.  While there, I also
implemented folding of invoke ranges - successive
ranges are merged when safe to do so.  Finally, if
a selector contains only a cleanup, there's a special
shorthand for it - place a 0 in the call-site entry.
I implemented this while there.  As a result, the
exception table output (excluding filters) is now
optimal - it cannot be made smaller [2].  The
problem with throw filters is that folding them
optimally is hard, and the benefit of folding them is
minimal.

[1] I tested that having trapping instructions (eg
divide by zero) in such a region doesn't cause trouble.
[2] It could be made smaller with the help of higher
layers, eg by having branch folding reorder basic blocks
ending in invokes with the same landing pad so they
follow each other.  I don't know if this is worth doing.

Evan Cheng 1ad4a6117b Change LiveRange so it keeps a pointer to the VNInfo rather than an index. 
Changes related modules so VNInfo's are not copied. This decrease

Evan Cheng a5b10b334f Recover most of the compile time regression due to recent live interval changes. 
1. Eliminate the costly live interval "swapping".
2. Change ValueNumberInfo container from SmallVector to std::vector. The former
   performs slowly when the vector size is very large.
