From fc6db97a09e2de5eff10131ddcab9cf8fb2f736c Mon Sep 17 00:00:00 2001 From: Lioncash Date: Tue, 3 Nov 2020 19:54:53 -0500 Subject: [PATCH] core: Remove usage of unicorn Unicorn long-since lost most of its use, due to dynarmic gaining support for handling most instructions. At this point any further issues encountered should be used to make dynarmic better. This also allows us to remove our dependency on Python. --- .gitmodules | 3 - .travis/linux-mingw/docker.sh | 10 +- .travis/linux/docker.sh | 2 +- .travis/macos/build.sh | 3 +- CMakeLists.txt | 77 ------ CMakeModules/CopyYuzuUnicornDeps.cmake | 9 - externals/unicorn | 1 - src/core/CMakeLists.txt | 4 +- src/core/arm/dynarmic/arm_dynarmic_32.cpp | 1 + src/core/arm/dynarmic/arm_dynarmic_64.cpp | 29 +-- src/core/arm/dynarmic/arm_dynarmic_64.h | 2 - src/core/arm/unicorn/arm_unicorn.cpp | 295 ---------------------- src/core/arm/unicorn/arm_unicorn.h | 63 ----- src/core/hle/kernel/physical_core.cpp | 16 +- src/core/hle/kernel/thread.cpp | 17 +- src/yuzu/CMakeLists.txt | 2 - src/yuzu_cmd/CMakeLists.txt | 2 - src/yuzu_tester/CMakeLists.txt | 2 - 18 files changed, 18 insertions(+), 520 deletions(-) delete mode 100644 CMakeModules/CopyYuzuUnicornDeps.cmake delete mode 160000 externals/unicorn delete mode 100644 src/core/arm/unicorn/arm_unicorn.cpp delete mode 100644 src/core/arm/unicorn/arm_unicorn.h diff --git a/.gitmodules b/.gitmodules index 6931a641d7..41022615bd 100644 --- a/.gitmodules +++ b/.gitmodules @@ -7,9 +7,6 @@ [submodule "dynarmic"] path = externals/dynarmic url = https://github.com/MerryMage/dynarmic.git -[submodule "unicorn"] - path = externals/unicorn - url = https://github.com/yuzu-emu/unicorn [submodule "soundtouch"] path = externals/soundtouch url = https://github.com/citra-emu/ext-soundtouch.git diff --git a/.travis/linux-mingw/docker.sh b/.travis/linux-mingw/docker.sh index 28033acfb1..80d7dfe9b8 100755 --- a/.travis/linux-mingw/docker.sh +++ b/.travis/linux-mingw/docker.sh @@ -4,16 +4,8 @@ cd /yuzu # override Travis CI unreasonable ccache size echo 'max_size = 3.0G' > "$HOME/.ccache/ccache.conf" -# Dirty hack to trick unicorn makefile into believing we are in a MINGW system -mv /bin/uname /bin/uname1 && echo -e '#!/bin/sh\necho MINGW64' >> /bin/uname -chmod +x /bin/uname - -# Dirty hack to trick unicorn makefile into believing we have cmd -echo '' >> /bin/cmd -chmod +x /bin/cmd - mkdir build && cd build -cmake .. -G Ninja -DCMAKE_TOOLCHAIN_FILE="$(pwd)/../CMakeModules/MinGWCross.cmake" -DUSE_CCACHE=ON -DYUZU_USE_BUNDLED_UNICORN=ON -DENABLE_COMPATIBILITY_LIST_DOWNLOAD=ON -DCMAKE_BUILD_TYPE=Release +cmake .. -G Ninja -DCMAKE_TOOLCHAIN_FILE="$(pwd)/../CMakeModules/MinGWCross.cmake" -DUSE_CCACHE=ON -DENABLE_COMPATIBILITY_LIST_DOWNLOAD=ON -DCMAKE_BUILD_TYPE=Release ninja # Clean up the dirty hacks diff --git a/.travis/linux/docker.sh b/.travis/linux/docker.sh index 3a9970384a..166fb6d4c2 100755 --- a/.travis/linux/docker.sh +++ b/.travis/linux/docker.sh @@ -3,7 +3,7 @@ cd /yuzu mkdir build && cd build -cmake .. -G Ninja -DYUZU_USE_BUNDLED_UNICORN=ON -DYUZU_USE_QT_WEB_ENGINE=ON -DCMAKE_BUILD_TYPE=Release -DCMAKE_C_COMPILER=/usr/lib/ccache/gcc -DCMAKE_CXX_COMPILER=/usr/lib/ccache/g++ -DYUZU_ENABLE_COMPATIBILITY_REPORTING=${ENABLE_COMPATIBILITY_REPORTING:-"OFF"} -DENABLE_COMPATIBILITY_LIST_DOWNLOAD=ON -DUSE_DISCORD_PRESENCE=ON +cmake .. -G Ninja -DYUZU_USE_QT_WEB_ENGINE=ON -DCMAKE_BUILD_TYPE=Release -DCMAKE_C_COMPILER=/usr/lib/ccache/gcc -DCMAKE_CXX_COMPILER=/usr/lib/ccache/g++ -DYUZU_ENABLE_COMPATIBILITY_REPORTING=${ENABLE_COMPATIBILITY_REPORTING:-"OFF"} -DENABLE_COMPATIBILITY_LIST_DOWNLOAD=ON -DUSE_DISCORD_PRESENCE=ON ninja ccache -s diff --git a/.travis/macos/build.sh b/.travis/macos/build.sh index 0abd1a93a2..db1c7cae7d 100755 --- a/.travis/macos/build.sh +++ b/.travis/macos/build.sh @@ -4,13 +4,12 @@ set -o pipefail export MACOSX_DEPLOYMENT_TARGET=10.14 export Qt5_DIR=$(brew --prefix)/opt/qt5 -export UNICORNDIR=$(pwd)/externals/unicorn export PATH="/usr/local/opt/ccache/libexec:$PATH" # TODO: Build using ninja instead of make mkdir build && cd build cmake --version -cmake .. -DYUZU_USE_BUNDLED_UNICORN=ON -DYUZU_USE_QT_WEB_ENGINE=ON -DCMAKE_BUILD_TYPE=Release -DENABLE_COMPATIBILITY_LIST_DOWNLOAD=ON -DYUZU_ENABLE_COMPATIBILITY_REPORTING=${ENABLE_COMPATIBILITY_REPORTING:-"OFF"} -DUSE_DISCORD_PRESENCE=ON +cmake .. -DYUZU_USE_QT_WEB_ENGINE=ON -DCMAKE_BUILD_TYPE=Release -DENABLE_COMPATIBILITY_LIST_DOWNLOAD=ON -DYUZU_ENABLE_COMPATIBILITY_REPORTING=${ENABLE_COMPATIBILITY_REPORTING:-"OFF"} -DUSE_DISCORD_PRESENCE=ON make -j4 ccache -s diff --git a/CMakeLists.txt b/CMakeLists.txt index 1bd9d2aa73..8fc2de042b 100644 --- a/CMakeLists.txt +++ b/CMakeLists.txt @@ -18,8 +18,6 @@ CMAKE_DEPENDENT_OPTION(YUZU_USE_BUNDLED_QT "Download bundled Qt binaries" ON "EN option(ENABLE_WEB_SERVICE "Enable web services (telemetry, etc.)" ON) -option(YUZU_USE_BUNDLED_UNICORN "Build/Download bundled Unicorn" ON) - option(YUZU_USE_QT_WEB_ENGINE "Use QtWebEngine for web applet implementation" OFF) option(YUZU_ENABLE_BOXCAT "Enable the Boxcat service, a yuzu high-level implementation of BCAT" ON) @@ -372,81 +370,6 @@ endif() set(THREADS_PREFER_PTHREAD_FLAG ON) find_package(Threads REQUIRED) -# If unicorn isn't found, msvc -> download bundled unicorn;
