I'd guess these are virtual function calls.

I am coming up against a lot of function pointers in the IR, although the corresponding source code does not have indirect calls. For example: call void %1608(%"struct.LRT::RGBAucharFrameBuffer"* %1604) How can I resolve the targets of these? Also, why are they appearing as indirect calls in the IR, when they are direct calls in the source? Thanks. -Apala

Hi all, We consistently see test failures arising because by default many of our tests run in a mode where the tool (clang or llc) pick host-dependent behavior. This makes it easy for developers to write tests that pass on their system, but fail for other developers. There is some utility in this behavior, as it gives us (unintended) testing coverage of some things, but overall I think it is a

...rnalWeightPostingSource.h I'd just put the get_weight() and get_maxweight() implementations into your ExternalWeightPostingSource class - the WeightSource class doesn't seem to serve a useful purpose and just adds virtual method call overheads (and those can add up, unless the compiler can devirtualise the calls, which compilers are getting better at). In the python example, the WeightSource class is just meant to be a placeholder for "some source of weights" - it isn't meant to be a literal recommendation for how to write such a class. > But we found that using PostingSource i...

Hi Tim, This is C++ indeed. Basically, I am profiling the code. So, these edges that cannot be resolved at compile time present a problem. Where can I find these devirtualization optimizations that you mentioned?

The proposed addition to ProgrammersManuel.rst is below the break... This is essentially trying to explain the emerging design techniques being used in LLVM these days somewhere more accessible than the comments on a particular piece of infrastructure. It covers the "concepts-based polymorphism" that caused some confusion during initial reviews of the new pass manager as well as the

I'm ok with this in principle, but how about with the nuance that some tests (eg test/codegen) explicitly opt into march=native? -Chris On Nov 30, 2012, at 12:16 PM, Daniel Dunbar <daniel at zuster.org> wrote: > Hi all, > > We consistently see test failures arising because by default many of our tests run in a mode where the tool (clang or llc) pick host-dependent behavior.

I’ve almost finished a patch to add back in either out of line destructors or anchor methods. We seem to use one or the one, relatively inconsistently. What i’ve gone for is that if a class already had an inline destructor then i left it alone and added an anchor method. Otherwise I added an out of line destructor. Now if I compile Instructions.cpp with -Wweak-vtable, the only warnings given
