[PATCH v5] ddraw: Implement Pick() and GetPickRecords().
by Myah Caron Sept. 18, 2020

Sept. 18, 2020

From: Matthew Wong <itsmattkc(a)gmail.com> Implement functions used by some games (notably LEGO Island) for determining which 3D object in a scene was clicked by the mouse cursor. Fighting Steel also uses this function for mouse over. Previous stubs would cause LEGO Island to crash upon any click and Fighting Steel to crash on game start. A patch posted years ago on the bug thread provided the minimum functionality to prevent crashes, but still rendered large portions of the game inaccessible without them implemented correctly. Picking has been implemented by adding a "pick mode" in d3d_execute_buffer_execute() which skips any drawing functions leaving just the vertex processing. Adds click tests for each triangle when in pick mode for creating an array of D3DPICKRECORDs. Stress testing reveals this patch's Pick() implementation may have slight inaccuracies to the original function; occasionally pixels right on triangle edges result in successful picks when they don't with the original function (and vice versa). It may be some sort of floating point rounding error or other algorithm difference that would be difficult to determine without seeing the original code. In practice, I believe this inaccuracy is so negligible that it won't produce any undesirable results for the user. Wine-Bug: https://bugs.winehq.org/show_bug.cgi?id=10729 Signed-off-by: Matthew Wong <itsmattkc(a)gmail.com> Signed-off-by: Myah Caron <qsniyg(a)protonmail.com> --- v5: Don't set device->pick_record_count = 0 in GetPickRecords, confirming Stefan's comment. Matthew's original patch is available here: https://www.winehq.org/pipermail/wine-devel/2019-August/149695.html. This version addresses the corrections Stefan pointed out here: https://www.winehq.org/pipermail/wine-devel/2019-November/154023.html. I've removed the "Add a" paragraphs from the commit message, primarily because the first one is now inaccurate due to the corrections. One comment I have (purposefully) not addressed is the last one referring to the corner case. This is because I know next to nothing about ddraw, and I don't have a testing machine on-hand either (only a VM). This also means that the new tests I have added are entirely untested on a native machine, so I'll have to rely on Marvin. I also have not addressed the WINED3D_MAP_WRITE comment, as if WINED3D_MAP_READ is used, most tests fail with the following error: warn:d3d:wined3d_resource_map Resource does not have MAP_R access. Regarding this comment: >The other question - to be answered by extending the test - is which >count is used here. Should you copy all pick records in the device, or >*count pick records, or whichever is smaller, or return an error if >*count < device->pick_record_count. I have added rec_count = 0 for the following to explicitly test for this: rec_count = 0; hr = IDirect3DDevice_GetPickRecords(device, &rec_count, NULL); However, since rec_count should have already been set to 0 if the previous GetPickRecords test passed, I believe this means that the inputted count variable is ignored by GetPickRecords. dlls/ddraw/ddraw_private.h | 7 +- dlls/ddraw/device.c | 65 +++++++++++-- dlls/ddraw/executebuffer.c | 194 +++++++++++++++++++++++++++++++++++-- dlls/ddraw/tests/ddraw1.c | 131 +++++++++++++++++++++++++ 4 files changed, 381 insertions(+), 16 deletions(-) diff --git a/dlls/ddraw/ddraw_private.h b/dlls/ddraw/ddraw_private.h index 776f61e1024..9d32aa61b1a 100644 --- a/dlls/ddraw/ddraw_private.h +++ b/dlls/ddraw/ddraw_private.h @@ -335,6 +335,11 @@ struct d3d_device struct d3d_viewport *current_viewport;

[PATCH] rpcrt4: Fix ARM64 stack corruption in call_server_func.
by Kevin Puetz Sept. 18, 2020

Sept. 18, 2020

calls with stack_size > 16 pop argument values into x3, overwriting the number of 16-byte stack octwords. This breaks the checks for popping x4..x7 and potentially unbalances sp (based on the vaue of args[16..23]). Use a scratch register (x9) for this count so its lifetime does not conflict with preparing the parameter/result registers.

[PATCH v4] ddraw: Implement Pick() and GetPickRecords().
by Myah Caron Sept. 18, 2020

Sept. 18, 2020

>From 2d32f46c241079fa449a24dcf6f255d59fe1cbe5 Mon Sep 17 00:00:00 2001 From: Myah Caron <qsniyg(a)protonmail.com> Date: Thu, 17 Sep 2020 13:53:38 -0700 Subject: [PATCH v4] ddraw: Implement Pick() and GetPickRecords(). From: Matthew Wong <itsmattkc(a)gmail.com> Implement functions used by some games (notably LEGO Island) for determining which 3D object in a scene was clicked by the mouse cursor. Fighting Steel also uses this function for mouse over. Previous stubs would cause LEGO Island to crash upon any click and Fighting Steel to crash on game start. A patch posted years ago on the bug thread provided the minimum functionality to prevent crashes, but still rendered large portions of the game inaccessible without them implemented correctly. Picking has been implemented by adding a "pick mode" in d3d_execute_buffer_execute() which skips any drawing functions leaving just the vertex processing. Adds click tests for each triangle when in pick mode for creating an array of D3DPICKRECORDs. Stress testing reveals this patch's Pick() implementation may have slight inaccuracies to the original function; occasionally pixels right on triangle edges result in successful picks when they don't with the original function (and vice versa). It may be some sort of floating point rounding error or other algorithm difference that would be difficult to determine without seeing the original code. In practice, I believe this inaccuracy is so negligible that it won't produce any undesirable results for the user. Wine-Bug: https://bugs.winehq.org/show_bug.cgi?id=10729 Signed-off-by: Matthew Wong <itsmattkc(a)gmail.com> Signed-off-by: Myah Caron <qsniyg(a)protonmail.com> --- v4: Don't check "count" variable as windows doesn't do this (according to tests) Matthew's original patch is available here: https://www.winehq.org/pipermail/wine-devel/2019-August/149695.html. This version addresses the corrections Stefan pointed out here: https://www.winehq.org/pipermail/wine-devel/2019-November/154023.html. I've removed the "Add a" paragraphs from the commit message, primarily because the first one is now inaccurate due to the corrections. The only comment I have (purposefully) not addressed is the last one referring to the corner case. This is because I know next to nothing about ddraw, and I don't have a testing machine on-hand either (only a VM). This also means that the new tests I have added are entirely untested on a native machine, so I'll have to rely on Marvin. Regarding this comment: >The other question - to be answered by extending the test - is which >count is used here. Should you copy all pick records in the device, or >*count pick records, or whichever is smaller, or return an error if >*count < device->pick_record_count. I have added rec_count = 0 for the following to explicitly test for this: rec_count = 0; hr = IDirect3DDevice_GetPickRecords(device, &rec_count, NULL); However, since rec_count should have already been set to 0 if the previous GetPickRecords test passed, I believe this means that the inputted count variable is ignored by GetPickRecords. dlls/ddraw/ddraw_private.h | 7 +- dlls/ddraw/device.c | 68 +++++++++++-- dlls/ddraw/executebuffer.c | 194 +++++++++++++++++++++++++++++++++++-- dlls/ddraw/tests/ddraw1.c | 131 +++++++++++++++++++++++++ 4 files changed, 384 insertions(+), 16 deletions(-) diff --git a/dlls/ddraw/ddraw_private.h b/dlls/ddraw/ddraw_private.h index 776f61e1024..9d32aa61b1a 100644 --- a/dlls/ddraw/ddraw_private.h +++ b/dlls/ddraw/ddraw_private.h @@ -335,6 +335,11 @@ struct d3d_device struct d3d_viewport *current_viewport;

[PATCH v3] ddraw: Implement Pick() and GetPickRecords().
by Myah Caron Sept. 17, 2020

Sept. 17, 2020

From: Matthew Wong <itsmattkc(a)gmail.com> Implement functions used by some games (notably LEGO Island) for determining which 3D object in a scene was clicked by the mouse cursor. Fighting Steel also uses this function for mouse over. Previous stubs would cause LEGO Island to crash upon any click and Fighting Steel to crash on game start. A patch posted years ago on the bug thread provided the minimum functionality to prevent crashes, but still rendered large portions of the game inaccessible without them implemented correctly. Picking has been implemented by adding a "pick mode" in d3d_execute_buffer_execute() which skips any drawing functions leaving just the vertex processing. Adds click tests for each triangle when in pick mode for creating an array of D3DPICKRECORDs. Stress testing reveals this patch's Pick() implementation may have slight inaccuracies to the original function; occasionally pixels right on triangle edges result in successful picks when they don't with the original function (and vice versa). It may be some sort of floating point rounding error or other algorithm difference that would be difficult to determine without seeing the original code. In practice, I believe this inaccuracy is so negligible that it won't produce any undesirable results for the user. Wine-Bug: https://bugs.winehq.org/show_bug.cgi?id=10729 Signed-off-by: Matthew Wong <itsmattkc(a)gmail.com> Signed-off-by: Myah Caron <qsniyg(a)protonmail.com> --- Matthew's original patch is available here: https://www.winehq.org/pipermail/wine-devel/2019-August/149695.html. This version addresses the corrections Stefan pointed out here: https://www.winehq.org/pipermail/wine-devel/2019-November/154023.html. I've removed the "Add a" paragraphs from the commit message, primarily because the first one is now inaccurate due to the corrections. The only comment I have (purposefully) not addressed is the last one referring to the corner case. This is because I know next to nothing about ddraw, and I don't have a testing machine on-hand either (only a VM). This also means that the new tests I have added are entirely untested on a native machine, so I'll have to rely on Marvin. Regarding this comment: >The other question - to be answered by extending the test - is which >count is used here. Should you copy all pick records in the device, or >*count pick records, or whichever is smaller, or return an error if >*count < device->pick_record_count. I have added rec_count = 0 for the following to explicitly test for this: rec_count = 0; hr = IDirect3DDevice_GetPickRecords(device, &rec_count, NULL); However, since rec_count should have already been set to 0 if the previous GetPickRecords test passed, I believe this means that the inputted count variable is ignored by GetPickRecords. dlls/ddraw/ddraw_private.h | 7 +- dlls/ddraw/device.c | 72 ++++++++++++-- dlls/ddraw/executebuffer.c | 194 +++++++++++++++++++++++++++++++++++-- dlls/ddraw/tests/ddraw1.c | 138 ++++++++++++++++++++++++++ 4 files changed, 395 insertions(+), 16 deletions(-) diff --git a/dlls/ddraw/ddraw_private.h b/dlls/ddraw/ddraw_private.h index 776f61e1024..9d32aa61b1a 100644 --- a/dlls/ddraw/ddraw_private.h +++ b/dlls/ddraw/ddraw_private.h @@ -335,6 +335,11 @@ struct d3d_device struct d3d_viewport *current_viewport;

[PATCH v3 0/4] First 4 patches of some ITypeInfo fixes
by Kevin Puetz Sept. 17, 2020

Sept. 17, 2020

This is a (partial) resend, per comments that a previous 13-part series was just too much at once (and it did in fact just age off the patch queue without any further reply, so zf was obviously correct) https://www.winehq.org/pipermail/wine-devel/2020-August/171427.html is the previous full series if anyone *would* like more context of what what bug(s) this is headed toward. But here's a smaller bite that can stand alone. Mostly just thickens up the test_dump_typelib conformance test coverage, fixing one minor widl bug that was found. Note that most of the changes are just insertions/formatting in static const type_info info[], which is autogenerated data being printed or verified by the few lines of code change that *aren't* that. Kevin Puetz (4): oleaut32/tests: reformat test_dump_typelib. oleaut32/tests: Fix expect_wstr_acpval(...,NULL). widl: all VARDESC fields of TKIND_UNION should have oInst=0. oleaut32/tests: Cover GetVarDesc in test_dump_typelib. dlls/oleaut32/tests/typelib.c | 536 ++++++++++++++++++++++++++++++---- tools/widl/write_msft.c | 3 +- 2 files changed, 484 insertions(+), 55 deletions(-)

[PATCH resend] winebuild: Find main/wmain in static libraries.
by Kevin Puetz Sept. 17, 2020

Sept. 17, 2020

Have the winebuild -spec.o include an undefined .globl referencing symbols we know the winecrt0 entry point will eventually reference, so ld knows about what it needs before scanning library archives. Signed-off-by: Kevin Puetz <PuetzKevinA(a)JohnDeere.com> --- wine.exe.so files set __wine_spec_exe_entry as the entry point. Therefore the linker is not initially looking for main and will pass over objects in lib.a archives that might provide it. When it gets to libwinecrt0.a is reached, it finds __wine_spec_exe_entry and learns that this wants main, but the resulting rescan will find the winecrt0 definition in terms of WinMain, before rescanning earlier libraries. So only a direct .o file (which is never passed over) can override the winecrt0 definition, and libraries like -lgtest_main do not work. --- tools/winebuild/build.h | 2 ++ tools/winebuild/main.c | 22 ++++++++++++++++++++-- tools/winebuild/spec32.c | 12 ++++++++++++ tools/winegcc/winegcc.c | 4 ++-- 4 files changed, 36 insertions(+), 4 deletions(-) diff --git a/tools/winebuild/build.h b/tools/winebuild/build.h index 03715af956..a4b9bc97e3 100644 --- a/tools/winebuild/build.h +++ b/tools/winebuild/build.h @@ -136,6 +136,7 @@ typedef struct int subsystem; /* subsystem id */ int subsystem_major; /* subsystem version major number */ int subsystem_minor; /* subsystem version minor number */ + int unicode_app; /* default to unicode entry point */ ORDDEF *entry_points; /* dll entry points */ ORDDEF **names; /* array of entry point names (points into entry_points) */ ORDDEF **ordinals; /* array of dll ordinals (points into entry_points) */ @@ -299,6 +300,7 @@ extern void output_gnu_stack_note(void); extern void add_import_dll( const char *name, const char *filename ); extern void add_delayed_import( const char *name ); extern void add_extra_ld_symbol( const char *name ); +extern void add_spec_extra_ld_symbol( const char *name ); extern void read_undef_symbols( DLLSPEC *spec, char **argv ); extern void resolve_imports( DLLSPEC *spec ); extern int is_undefined( const char *name ); diff --git a/tools/winebuild/main.c b/tools/winebuild/main.c index 0e5e1627dd..68137b0f4c 100644 --- a/tools/winebuild/main.c +++ b/tools/winebuild/main.c @@ -396,8 +396,25 @@ static const char *get_default_entry_point( const DLLSPEC *spec ) { if (spec->characteristics & IMAGE_FILE_DLL) return "DllMain"; if (spec->subsystem == IMAGE_SUBSYSTEM_NATIVE) return "DriverEntry"; - if (spec->type == SPEC_WIN16) return "__wine_spec_exe16_entry"; - return "__wine_spec_exe_entry"; + if (spec->type == SPEC_WIN16) { + add_spec_extra_ld_symbol("WinMain16"); + return "__wine_spec_exe16_entry"; + } + if (spec->unicode_app) { + /* __wine_spec_exe_wentry always calls wmain */ + add_spec_extra_ld_symbol("wmain"); + if(spec->subsystem == IMAGE_SUBSYSTEM_WINDOWS_GUI) { + add_spec_extra_ld_symbol("wWinMain"); + } + return "__wine_spec_exe_wentry"; + } else { + /* __wine_spec_exe_entry always calls main */ + add_spec_extra_ld_symbol("main"); + if(spec->subsystem == IMAGE_SUBSYSTEM_WINDOWS_GUI) { + add_spec_extra_ld_symbol("WinMain"); + } + return "__wine_spec_exe_entry"; + } } /* parse options from the argv array and remove all the recognized ones */ @@ -448,6 +465,7 @@ static char **parse_options( int argc, char **argv, DLLSPEC *spec ) else if (!strcmp( optarg, "thumb" )) thumb_mode = 1; else if (!strcmp( optarg, "no-cygwin" )) use_msvcrt = 1; else if (!strcmp( optarg, "unix" )) unix_lib = 1; + else if (!strcmp( optarg, "unicode" )) spec->unicode_app = 1; else if (!strncmp( optarg, "cpu=", 4 )) cpu_option = xstrdup( optarg + 4 ); else if (!strncmp( optarg, "fpu=", 4 )) fpu_option = xstrdup( optarg + 4 ); else if (!strncmp( optarg, "arch=", 5 )) arch_option = xstrdup( optarg + 5 ); diff --git a/tools/winebuild/spec32.c b/tools/winebuild/spec32.c index efb136a8e6..02ad498e35 100644 --- a/tools/winebuild/spec32.c +++ b/tools/winebuild/spec32.c @@ -50,6 +50,13 @@ int needs_get_pc_thunk = 0; static const char builtin_signature[32] = "Wine builtin DLL"; static const char fakedll_signature[32] = "Wine placeholder DLL"; +static struct strarray spec_extra_ld_symbols = { 0 }; /* list of extra symbols that ld should resolve */ + +/* add a symbol to the list of extra symbols that ld must resolve */ +void add_spec_extra_ld_symbol( const char *name ) +{ + strarray_add( &spec_extra_ld_symbols, name, NULL ); +} /* check if entry point needs a relay thunk */ static inline int needs_relay( const ORDDEF *odp ) @@ -602,6 +609,7 @@ void output_exports( DLLSPEC *spec ) void output_module( DLLSPEC *spec ) { int machine = 0; + int i; unsigned int page_size = get_page_size(); const char *data_dirs[16] = { NULL }; @@ -680,6 +688,10 @@ void output_module( DLLSPEC *spec ) output( "\t.long 0\n" ); /* SizeOfCode */ output( "\t.long 0\n" ); /* SizeOfInitializedData */ output( "\t.long 0\n" ); /* SizeOfUninitializedData */ + + for (i = 0; i < spec_extra_ld_symbols.count; i++) + output( "\t.globl %s\n", asm_name(spec_extra_ld_symbols.str[i]) ); + /* note: we expand the AddressOfEntryPoint field on 64-bit by overwriting the BaseOfCode field */ output( "\t%s %s\n", /* AddressOfEntryPoint */ get_asm_ptr_keyword(), spec->init_func ? asm_name(spec->init_func) : "0" ); diff --git a/tools/winegcc/winegcc.c b/tools/winegcc/winegcc.c index bbb44ff614..2cb122613e 100644 --- a/tools/winegcc/winegcc.c +++ b/tools/winegcc/winegcc.c @@ -1239,8 +1239,6 @@ static void build(struct options* opts) entry_point = (is_pe && opts->target_cpu == CPU_x86) ?
