1. The dynamic loaders should not be needed for loading minidumps and they may create problems (ex. the macOS loader resets the list of loaded sections, which for minidumps are already set up during minidump loading) 2. In general, the extra plugins can do extraneous work which hurts performance (ex. trying to set up implicit symbolic breakpoints, which in turn will trigger extra debug information loading) Differential Revision: https://reviews.llvm.org/D51176 llvm-svn: 340578
