[llvm-dev] ORC JIT Weekly #18 -- TargetProcessControl updates for library loading / searching.
Hi All, This was a quiet week -- the only significant ORC change was to the new TargetProcessControl API [1], which acquired the ability to load libraries and search for symbols in the target process in [2]. A new TargetProcessControl based definition generator is included to take advantage of this, and the LLJITWithTargetProcessControl example has been updated to include it. Regards, Lang.

[llvm-dev] ORC JIT Weekly #18 -- TargetProcessControl updates for library loading / searching.
Hi Lang Thanks for the update! Is there a conceptual difference between the old: DynamicLibrarySearchGenerator::GetForCurrentProcess(<SystemManglingPrefix>) and the newly added TCP-based one (when applied to the own process): TPCDynamicLibrarySearchGenerator::GetForTargetProcess(SelfTargetProcessControl::Create()) Or can we just assume it the preferred, more generalized approach for constructing definition generators from now on?> Near term ORC work will focus on expanding TargetProcessControl, improving > JITLink's ELF support, ...Sounds great!

The TargetProcessControl method needs some road-testing, but should eventually be the preferred method. DynamicLibrarySearchGenerator will remain available for quite a while for the sake of clients who can't use TargetProcessControl, e.g. people using RuntimeDyld with a custom memory manager.
