[cfe-users] How to 'reloop' llvm code into ifs, whiles, fors?

[Hugh Perkins via cfe-users]

Hi,

I have a project to rewrite llvm output as OpenCL,
https://github.com/hughperkins/cuda-on-cl  It currently contains lots of
conditional branches, whch become /labels / gotos in the output OpenCL.

What options are available to 'reloop' this to contain strictly
ifs/fors/switches/breaks/whiles ?

Hugh
