[pypy-dev] Patchpoints in LLVM

[Dimitri Vorona]

Hi,

just wanted to link this discussion
http://lists.cs.uiuc.edu/pipermail/llvmdev/2013-October/066573.html and
this piece of docs http://llvm.org/docs/StackMaps.html. As far as I
understand, the lack of patchpoints (i.e. a way to patch dynamically
generated code) was the major burden on the way to use LLVM for code
generation for PyPy.

The functionality was implemented as a part of FTL, LLVM-based JavaScript
compiler (http://blog.llvm.org/2014/07/ftl-webkits-llvm-based-jit.html)

Regards,
Dimitri.
