[llvm-commits] VM hooks when locking

[Nicolas Geoffray]

Hi all,

Is it OK to apply this patch? It provides hooks for llvm users 
(especially VM implementors) to control when a thread blocks on a mutex. 
It is very useful if the VM wants to know the state of each thread it is 
running.

The changes may probably be too ad-hoc for being integrated in llvm, but 
that's the simplest solution I came up with.
