ToDos on Parallel GCC Wiki

[Nicholas Krause <xerofoify@gmail.com>]

Greetings Richard,

Seems some of these things can either be closed or discussed here:

Add support to a multithread environment to Garbage Collector:

This may not matter as memory is in bulk at the beginning of passes. 
I've benchmarked

it and its less than 5% on the GCC test farm machines with make -j64.

Parallelize RTL part. This will improve our current results, as 
indicated in Results chapter:

struct function or function.c if I recall is using the most as one file 
at around 20-30% for

sure in building gcc with make -j64.

Make this GCC compile itself:

It does  now and I just tested it but I assuming he means with threads 
on and I'm not sure how

to enable them in the core Makefile for gcc or if just exporting CC/CXX 
is earlier with it

turned on.

I've also looked into the Linux Kernel work queues as those can scale 
much better than just

launching in async as we are doing currently. On the  testingside seems 
the Yocto Project is

working on testing upstream heads of projects like gcc. I've asked them 
to bring it up at the

usual IOT/Embedded Linux Conference meeting. This will also us to have 
access to not only

the gcc testsuite but access to build lots of real world software 
packages in a pretty automated

way as that was one concern that Giuliano brought up at the Cauldron 
this year.

Also if someone opens a more detailed ToDo with Bugs or something I 
would be able to help out more

or just CC on the issues or work that is ongoing as frankly seems I'm 
not been keeping good track,

Nick
