I don’t know what to make of them. The constructor for DILocation requires 5 arguments, and I don’t know what I would use as the arguments if I were to correct this code. Also, the type “DIDescriptor” apparently doesn’t exist: has it been renamed? What’s going on?<div class=""><br class=""></div><div class="">Thanks,</div><div class="">Peter Finn</div><div class=""><br class=""></div><div class=""><div style="margin: 0px; font-size: 11px; font-family: Menlo;" class="">llvm[2]: Compiling DebugInstrumentation.cpp for Debug+Asserts build</div><div style="margin: 0px;
