We used to have some hack for passing information (mainlyi module related ones) from dbghelp to WineDbg.
This series: - reimplements properly the sharing, introducing a Wine entrypoint to dbghelp (sharing debug formats not handled by native, no longer decorating module names for sharing that module was in fact a host module...) - improves "info share" command in WineDbg with more accurate information (host module type...) - improves loading time on MacOs (some system libraries no longer have their images accessible directly on disk by standard file operation).

From: Eric Pouech eric.pouech@gmail.com
On MacOs, starting with Big Sur 11.0.1, the system dynamic libraries are no longer directly accessible on disk. They are still avaible through dlopen and friends. For getting access to the images (and their debug symbol), Apple provides in the developper kit the tools to extract the files. Note that is handled as a database of all system libraries, where ASLR is in place such that segments of a given library are no longer contiguous in memory (dbghelp doesn't currently handle this).
A part from not having image information nor debug information, another side effect is that dbghelp tries every time it refreshes the mach-o module list to reload any library for which it didn't have an image file. This can be lengthy (esp when a typical process has more than 300 modules loaded).
This patch forces the creation of the dbghelp module even if the image file isn't found.
this patch cut startup time of 'winedbg notepad' from 9.9 to 7.4s. YMMV.
