Add a new feature to process save-core on Darwin systems -- for lldb to create a user process corefile with only the dirty (modified memory) pages included. All of the binaries that were used in the corefile are assumed to still exist on the system for the duration of the use of the corefile. A new --style option to process save-core is added, so a full corefile can be requested if portability across systems, or across time, is needed for this corefile. debugserver can now identify the dirty pages in a memory region when queried with qMemoryRegionInfo, and the size of vm pages is given in qHostInfo. Create a new "all image infos" LC_NOTE for Mach-O which allows us to describe all of the binaries that were loaded in the process -- load address, UUID, file path, segment load addresses, and optionally whether code from the binary was executing on any thread. The old "read dyld_all_image_infos and then the in-memory Mach-O load commands to get segment load addresses" no longer works when we only have dirty memory. rdar://69670807 Differential Revision: https://reviews.llvm.org/D88387 |
