[llvm-dev] pragma and function insertion
Dear community, For my project, I defined a #pragma and i would like clang to replace this pragma by a function call. After reading tutorials, I managed to write a plugin which is able to parse and recognize this pragma. Now I have some difficulties to transform this pragma into a function call. My comprehension is that I need first to declare a new annotation token and insert it in the stream. Then I should process this token and call the function I want. Is this approach correct? Can a frontendAction do this job? However, I have the feeling this process should be very common and probably the solution is already written somewhere ... Does anybody have a similar example? Thanks a lot ! -------------------- Julien Schmitt VSORA - immeuble LE PASTEUR 13/15 rue Jeanne Braconnier, 92360 Meudon La Forêt, France Mob : +33 6 66 81 08 76 Email: julien.schmitt at vsora.com Web: www.vsora.com<http://www.vsora.com> -------------- next part -------------- An HTML attachment was scrubbed...

Hi, several OpenMP directives do this, such as #pragma omp flush. It's handling is in StmtOpenMP.cpp (OMPFlushDirective) and CGOpenMPRuntime.cpp (CGOpenMPRuntime::emitFlush) Michael Am Do., 13.
