[reactos] 01/01: Replace our dxtn.dll by a version based on the libtxc_dxtn source code (#203)

by Colin Finck

https://git.reactos.org/?p=reactos.git;a=commitdiff;h=12b78f182da5f1c21ef4d… commit 12b78f182da5f1c21ef4d53b4c938a4bb346defa Author: Colin Finck <colin(a)reactos.org> AuthorDate: Wed Dec 20 11:15:13 2017 +0100 Replace our dxtn.dll by a version based on the libtxc_dxtn source code (#203) This is no official system DLL and WineD3D is its only user. But latest WineD3D prefers the libtxc_dxtn codebase instead of the alternative library we used. This is also what Mesa uses and Fedora ships now that the patents have expired, so we should stick to the same. I'm importing the libtxc_dxtn-1.0.1 codebase from https://people.freedesktop.org/~cbrill/libtxc_dxtn/ It compiles warning-free in our tree without modifying a single line! I'm merging this Pull Request based on the positive response in CORE-12759. I lack a proper test case myself, but my version at least shouldn't make things worse. In my opinion, the previous one was broken anyway due to using stdcall imports when WineD3D called cdecl ones. This also removes the NSWPAT option from our buildsystem as dxtn was its latest user. --- dll/3rdparty/CMakeLists.txt | 5 +- dll/3rdparty/dxtn/CMakeLists.txt | 9 +- dll/3rdparty/dxtn/dxtn.c | 757 -------------- dll/3rdparty/dxtn/dxtn.h | 62 -- dll/3rdparty/dxtn/dxtn.spec | 18 +- dll/3rdparty/dxtn/fxt1.c | 1369 -------------------------- dll/3rdparty/dxtn/fxt1.h | 38 - dll/3rdparty/dxtn/internal.h | 138 --- dll/3rdparty/dxtn/txc_compress_dxtn.c | 843 ++++++++++++++++ dll/3rdparty/dxtn/{texstore.c => txc_dxtn.h} | 53 +- dll/3rdparty/dxtn/txc_fetch_dxtn.c | 243 +++++ dll/3rdparty/dxtn/types.h | 11 - dll/3rdparty/dxtn/wrapper.c | 110 --- sdk/cmake/config-amd64.cmake | 6 - sdk/cmake/config-arm.cmake | 6 - sdk/cmake/config.cmake | 6 - 16 files changed, 1118 insertions(+), 2556 deletions(-) diff --git a/dll/3rdparty/CMakeLists.txt b/dll/3rdparty/CMakeLists.txt index 936727c7b3..4ef9d7bce5 100644 --- a/dll/3rdparty/CMakeLists.txt +++ b/dll/3rdparty/CMakeLists.txt @@ -1,8 +1,5 @@ -if(NSWPAT) - add_subdirectory(dxtn) -endif() - +add_subdirectory(dxtn) add_subdirectory(libjpeg) add_subdirectory(libpng) add_subdirectory(libtiff) diff --git a/dll/3rdparty/dxtn/CMakeLists.txt b/dll/3rdparty/dxtn/CMakeLists.txt index b399df447b..e2e95fb08c 100644 --- a/dll/3rdparty/dxtn/CMakeLists.txt +++ b/dll/3rdparty/dxtn/CMakeLists.txt @@ -2,15 +2,10 @@ spec2def(dxtn.dll dxtn.spec) add_library(dxtn SHARED - fxt1.c - dxtn.c - wrapper.c - texstore.c + txc_compress_dxtn.c + txc_fetch_dxtn.c ${CMAKE_CURRENT_BINARY_DIR}/dxtn.def) set_entrypoint(dxtn 0) add_importlibs(dxtn msvcrt) -if(NOT MSVC) - add_target_compile_flags(dxtn "-Wno-unused-but-set-variable") -endif() add_cd_file(TARGET dxtn DESTINATION reactos/system32 FOR all) diff --git a/dll/3rdparty/dxtn/dxtn.c b/dll/3rdparty/dxtn/dxtn.c deleted file mode 100644 index e6e5988c00..0000000000 --- a/dll/3rdparty/dxtn/dxtn.c +++ /dev/null @@ -1,757 +0,0 @@ -/* - * DXTn codec - * Version: 1.1 - * - * Copyright (C) 2004 Daniel Borca All Rights Reserved. - * - * this is free software; you can redistribute it and/or modify - * it under the terms of the GNU General Public License as published by - * the Free Software Foundation; either version 2, or (at your option) - * any later version. - * - * this is distributed in the hope that it will be useful, - * but WITHOUT ANY WARRANTY; without even the implied warranty of - * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
