OK. Bootstrap does proceed with the prototype removed, of course (it's
not yet finished).
Question is: can we remove it altogether, or are there still cases

Hi all,
i'm currently studing alias analysis, and i have some questions, for

If i'm not wrong the def-use chain connects a definition of a variable
to all the uses it may flow to, and the use-def chain connects a use
I've seen a weird warning during a bootstrap of mainline on native

ud chains are implicit in SSA form, since each use only has one

No, nothing is wrong wit he import, if you want all the remote
branches, you have to ask git to get all the remote branches
git config --add remote.origin.fetch '+refs/remotes/*:refs/remotes/*'
Then fetch again.
then, if you want to really see all the branches, including the remote
ones, use git

Hi there,
Over at the Boost C++ libraries project we're trying to decide what is the
correct thing to do when code is compiled with -pthread or not.
The crux of the issue is this: if gcc/g++ is configured with the pthread
threading model, then are object files always binary compatible irrespecti
