<html><body><p>Hi Dounia,<br><br>I work on the NVPTX OpenMP codegen support and we don't use fork() but I can point you to where you may be able to find this information.<br><br>In the clang sources, have a look at: lib/CodeGen/CGOpenMPRuntime.cpp and the function createRuntimeFunction where the call to __kmpc_fork_call() is created. The type of the outlined function can be had through the function: getKmpc_MicroPointerTy(). Is this what you are looking for?<br><br>Regards,<br>Arpith<br><br><tt>"Openmp-dev" <openmp-dev-bounces@lists.llvm.org> wrote on 07/30/2016 12:38:09 PM:<br><br>> From: via Openmp-dev <openmp-dev@lists.llvm.org></tt><br><tt>> To: Dounia Khaldi <khaldi.dounia@gmail.com>, openmp-dev@lists.llvm.org</tt><br><tt>> Cc: llvmdev@cs.uiuc.edu</tt><br><tt>> Date: 07/30/2016 12:38 PM</tt><br><tt>> Subject: Re: [Openmp-dev] [llvm-dev] How to get the function <br>> definition of a kmpc_micro call</tt><br><tt>> Sent by: "Openmp-dev" <openmp-dev-bounces@lists.llvm.org></tt><br><tt>> <br>> Adding openmp-dev list.</tt><br><tt>> <br>> 30 июля 2016 г., в 5:09, Dounia Khaldi via llvm-dev <llvm-dev@lists.llvm.org<br>> > написал(а):<br></tt><br><tt>> Hello,</tt><br><tt>> <br>> The third argument of the OpenMP runtime call __kmpc_fork_call is <br>> the outlined function resulting from omp parallel directive; this is<br>> of type kmpc_micro.
