[IDF][analyzer] Generalizing IDFCalculator to be used for Clang's CFG
A polite ping, could someone please share a thought about this?

Struggling with a PGO build of clang -- llvm-profdata was built without zlib support?
Yes, that was it! Now that I took a closer look, the guide also states that
I should use the stage2 build. Silly me.
Thanks!

Is bugzilla down?
It seems to be down again for me, anyone experiencing the same?

RFC: Introducing CfgTraits and type-erased CfgInterface / CfgBlockRef / CfgValueRef
Hi all,
This is a request for comment on a series of patches which introduce a
new way of writing algorithms that are generic over different types of CFG.
What is this?
=============
This series of patches introduces a set of classes and templates for:

the same algorithm implementation on both LLVM IR and MachineIR (in SSA

RFC: New aggressive dead code elimination pass
Some question:
1. IDFCalculator already allows reverse graphs, and gets used for that, so
what did you have to change? (this change was made in the past year, so i
wonder if you were working on a branch or something).
2. What are the actual numbers here in terms of calculation of IDF vs your
method.
IDF calculator is linear time (Well, depends on priority queue impl, but we
could fix that

Struggling with a PGO build of clang -- llvm-profdata was built without zlib support?
Hi!
I'm trying to build a fast Clang for myself to use for debug builds on
Clang itself, but I've been struggling for a very long time on it. Could
you please help?
I've been following this guide: https://llvm.org/docs/HowToBuildWithPGO.html
I've quickly learned that its outdated, because the script it talks about
doesn't work with the monorepo layout at all, but in any

RFC: Making a common successor/predecessor interface
Hi,
As part of an ongoing work to extend the GraphDiff (this models a CFG
view), I came across the need to have a common interface for accessing
successors/predecessors in various IR units, such that a type such as
`typename NodeT::succ_iterator` could be used in templated code.
In particular, the need arose for BasicBlocks, MachineBasicBlocks,
VPBlockBase and clang::CFGBlock.
The least invasive

RFC: Making a common successor/predecessor interface
Hi Dave,
It may be possible to do this with the current API, but what I was looking
for is a common API for existing block types. For example there is no
succ_begin for Machine BasicBlock.
I'm looking to make the CFGSuccessors and CFGPredecessors classes in
CFGDiff.h templated, and this needs a common API for all types
instantiations.
Does this clarify your question or did I misunderstand

Ogg Vorbis, Ogg Speex, Ogg FLAC
Now that FLAC has officionally joined the Xiph family,
there are three different free audio codecs, which can be
stored/transported using the ogg container.
Would it be possible to create an API and/or a library that
would cover them all?
If my understanding of the situation is correct, if an application wants
to support vorbis, speex and flac, it has to use three different
interfaces.

ambiguity in sample ices config files

Hi there!
Yesterday I downloaded the CVS version of icecast and ices.
There are several example config files provided for ices in the

The ices-playlist.xml specifies encoding for one of the instances:

Implementing the tf-idf weighting scheme
Hi, all:
This is the basic implementation of tf-idf scheme (basic scheme used in
SMART) that can be used in the Xapian. It might still need some futher
revision, but I believe it works anyway.:)
I modified the weight.h to define a subclass Tf_idfWeight and add a new
file tf_idf.cc in ../weight in the repo, to implement Tf_idfWeight.
Here is the git diff patch:

Sent a pull request for the Tf-Idf Weighting scheme
Hello guys :) I have sent a pull request for the Tf-Idf Weighting scheme
incorporating as many normalizations as I could with the help of statistics
currently available from Xapian::Weight . Please let me know what you'll
think about it.
I used the weighting scheme in a simple searcher and it did a fine job with
it. I have no experience with writing tests for features like this.Please
