[cfe-dev] GSOC Projects

I have some ideas for GSOC projects using LLVM, where should I post them?
Idea #1: llvm-env
A simple tool, with little or no dependency on LLVM itself, that will
investigate a target architecture by probing hardware, software, libraries
and compiling and executing code to identify all properties that would be
relevant to command-line options, triple settings etc.
The first stage is to build a CFLAGS for Clang that would produce code on
the current Host to the identified Target.
The second stage would be to produce a configuration file (that can be used
independently of the Host) so that Clang can read it and not need a
gazillion of command-line options. Such file should be simple JSON / INI or
anything that Vim could change.
Idea #2: LNT perf Monitor
The LNT perf database has some nice features like detect moving average,
standard deviations, variations, etc. But the report page give too much
emphasis on the individual variation (where noise can be higher than
The first part of the project would be to create an analysis tool that
would track moving averages and report:
* If the current result is higher/lower than the previous moving average
by more than (configurable) S standard deviations
* If the current moving average is more than S standard deviations of the
* If the last A moving averages are in constant increase/decrease of more
than P percent
The second part would be to create a web page which would show all related
benchmarks (possibly configurable, like a dashboard) and show the basic
statistics with red/yellow/green colour codes to show status and links to
more detailed analysis of each benchmark
A possible third part would be to be able to automatically cross reference
different builds, so that if you group them by architecture/compiler/number
of CPUs, this automated tool would understand that the changes are more
common to one particular group.
