[PATCH 0/7] MR430: dbghelp improvements
by eric pouech (＠epo) July 12, 2022

July 12, 2022

This series: - cleanups some code (using bitfield instead of hardcoded constants) - silences some FIXMEs in SymGetTypeInfo - fixes a couple of erroneous lexical relationship among dbghelp objects (mainly attaching - as native does - some objects to SymTagExe object) -- https://gitlab.winehq.org/wine/wine/-/merge_requests/430

[PATCH 0/1] MR427: ntdll: Preserve rbx register when calling DLL entry point on x64.
by Paul Gofman (＠gofman) July 11, 2022

July 11, 2022

Assassin's Creed Origins clobbers rbx in its main module (second of three) TLS callbacks. That is apparent right in the beginning of the TLS callback disassembly when rbx is set to '4' unconditionally without any prior save. That leads to a fault in call_tls_callbacks() which is still in __TRY block and gets handled. However the third TLS callback is not executed and that leads to intermittent hangs later on. It is rather involved to make a TLS callback test in Wine testsuite as there is no portable way to generate a custom TLS callback. I've made a test program (based on the example here: https://lallouslab.net/2017/05/30/using-cc-tls-callbacks-in-visual-studio-w…) and compiled it with MSVC. The source code is here: https://gist.github.com/gofman/3287a953bcab3a5c888a8d494461cb8a. The program calls all the callbacks on Windows 10 here. There is also a similar wrapper already there for i386 on another occasion. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/427

[PATCH 0/1] MR425: ntdll: Do not use find_subheap() to find the subheap corresponding to an uncommitted region.
by Zebediah Figura (＠zfigura) July 11, 2022

July 11, 2022

The commit end of a subheap may be equal to the beginning of another subheap, in which case find_subheap() will return that one, and we may effectively skip backwards in the subheap list. --- There may be a more architecturally palatable way to solve this problem, but hopefully this is enough to at least demonstrate it. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/425
