From: Pierre Ossman Date: Fri, 4 Jul 2014 12:12:49 +0000 (+0200) Subject: Add pixel conversion speed test X-Git-Tag: v1.3.90~47^2 X-Git-Url: https://source.dussan.org/?a=commitdiff_plain;h=refs%2Fpull%2F4%2Fhead;p=tigervnc.git Add pixel conversion speed test Add a tests directory where we can put tests programs that can be useful during testing. Start with a speed test for the pixel conversion routines. --- diff --git a/CMakeLists.txt b/CMakeLists.txt index 2593a64b..bdb1824a 100644 --- a/CMakeLists.txt +++ b/CMakeLists.txt @@ -416,6 +416,8 @@ if(BUILD_VIEWER) add_subdirectory(media) endif() +add_subdirectory(tests) + include(cmake/BuildPackages.cmake) diff --git a/tests/CMakeLists.txt b/tests/CMakeLists.txt new file mode 100644 index 00000000..fd47c15a --- /dev/null +++ b/tests/CMakeLists.txt @@ -0,0 +1,6 @@ +include_directories(${CMAKE_SOURCE_DIR}/common) + +add_library(test_util STATIC util.cxx) + +add_executable(pixelconv pixelconv.cxx) +target_link_libraries(pixelconv test_util rfb) diff --git a/tests/pixelconv.cxx b/tests/pixelconv.cxx new file mode 100644 index 00000000..ef9d3aac --- /dev/null +++ b/tests/pixelconv.cxx @@ -0,0 +1,201 @@ +#include +#include +#include +#include + +#include +#include + +#include "util.h" + +static const int tile = 64;
