:: Default to highest Visual Studio version available

:: and VS140COMNTOOLS is set as a global environment variable by the installer. This
:: allows users to locate where the instance of VS2015 is installed.
::
:: For VS2017, multiple instances can be installed on the same box SxS and VS150COMNTOOLS
:: is no longer set as a global environment variable and is instead only set if the user
:: has launched the VS2017 Developer Command Prompt.
::
:: Following this logic, we will default to the VS2017 toolset if VS150COMNTOOLS tools is
:: set, as this indicates the user is running from the VS2017 Developer Command Prompt and
:: is already configured to use that toolset. Otherwise, we will fallback to using the VS2015
:: toolset if it is installed. Finally, we will fail the script if no supported VS instance

:Usage
echo.
echo Build the CoreCLR repo.
echo.
echo Usage:
echo     build.cmd [option1] [option2]
echo or:
echo     build.cmd all [option1] [option2] -- ...
echo.
echo All arguments are optional. The options are:
echo.
echo.-? -h -help: view this message.
echo all: Builds all configurations and platforms.
echo Build architecture: one of x64, x86, arm, arm64 ^(default: x64^).
echo Build type: one of Debug, Checked, Release ^(default: Debug^).
echo -- ... : all arguments following this tag will be passed directly to msbuild.
echo mscorlib version: one of freebsdmscorlib, linuxmscorlib, netbsdmscorlib, osxmscorlib,
echo     or windowsmscorlib. If one of these is passed, only System.Private.CoreLib is built,
echo     for the specified platform ^(FreeBSD, Linux, NetBSD, OS X or Windows,
echo     respectively^).
echo     add nativemscorlib to go further and build the native image for designated mscorlib.
echo toolset_dir ^<dir^> : set the toolset directory -- Arm64 use only. Required for Arm64 builds.
echo nopgooptimize: do not use profile guided optimizations.
echo pgoinstrument: generate instrumented code for profile guided optimization enabled binaries.
echo ibcinstrument: generate IBC-tuning-enabled native images when invoking crossgen.
echo configureonly: skip all builds; only run CMake ^(default: CMake and builds are run^)
echo skipconfigure: skip CMake ^(default: CMake is run^)
echo skipmscorlib: skip building System.Private.CoreLib ^(default: System.Private.CoreLib is built^).
echo skipnative: skip building native components ^(default: native components are built^).
echo skiptests: skip building tests ^(default: tests are built^).
echo skipbuildpackages: skip building nuget packages ^(default: packages are built^).
echo skiprestoreoptdata: skip restoring optimization data used by profile-based optimizations.
echo buildstandalonegc: builds the GC in a standalone mode.
echo -skiprestore: skip restoring packages ^(default: packages are restored during build^).
echo -disableoss: Disable Open Source Signing for System.Private.CoreLib.
echo -priority=^<N^> : specify a set of test that will be built and run, with priority N.
echo -sequential: force a non-parallel build ^(default is to build in parallel
echo     using all processors^).
echo -officialbuildid=^<ID^>: specify the official build ID to be used by this build.
echo -Rebuild: passes /t:rebuild to the build projects.
echo portable : build for portable RID.
echo.
echo If "all" is specified, then all build architectures and types are built. If, in addition,
echo one or more build architectures or types is specified, then only those build architectures
echo and types are built.
echo.
echo For example:
echo     build all
echo        -- builds all architectures, and all build types per architecture
echo     build all x86
echo        -- builds all build types for x86
echo     build all x64 x86 Checked Release
echo        -- builds x64 and x86 architectures, Checked and Release build types for each

:NoDIA
echo Error: DIA SDK is missing at "%VSINSTALLDIR%DIA SDK". ^
This is due to a bug in the Visual Studio installer. It does not install DIA SDK at "%VSINSTALLDIR%" but rather ^
at the install location of previous Visual Studio version. The workaround is to copy the DIA SDK folder from the Visual Studio install location ^
of the previous version to "%VSINSTALLDIR%" and then build.
:: DIA SDK not included in Express editions
echo Visual Studio Express does not include the DIA SDK. ^
You need Visual Studio 2015 or 2017 (Community is free).
