.SYNOPSIS
Builds the Swift toolchain, installers, and optionally runs tests.
.DESCRIPTION
This script performs various steps associated with building the Swift toolchain:
- Builds the redistributable, SDK, devtools and toolchain binaries and files
- Builds the msi's and installer executable
- Creates a mock installation under S:\Program Files and S:\Library for local toolchain use
- Optionally runs tests for supported projects
- Optionally stages build artifacts for CI
.PARAMETER SourceCache
The path to a directory where projects contributing to the Swift.
toolchain have been cloned.
.PARAMETER BinaryCache
The path to a directory where to write build system files and outputs.
.PARAMETER ImageRoot
The path to a directory that mimics a file system image root,
under which "Library" and "Program Files" subdirectories will be created
with the files installed by CMake.
.PARAMETER CDebugFormat
The debug information format for C/C++ code: dwarf or codeview.
.PARAMETER SwiftDebugFormat
The debug information format for Swift code: dwarf or codeview.
.PARAMETER SDKs
An array of architectures for which the Swift SDK should be built.
.PARAMETER ProductVersion
The product version to be used when building the installer.
Supports semantic version strings.
.PARAMETER PinnedBuild
The toolchain snapshot to build the early components with.
.PARAMETER PinnedSHA256
The SHA256 for the pinned toolchain.
.PARAMETER WinSDKVersion
The version number of the Windows SDK to be used.
Overrides the value resolved by the Visual Studio command prompt.
If no such Windows SDK is installed, it will be downloaded from nuget.
.PARAMETER SkipBuild
If set, does not run the build phase.
.PARAMETER SkipPackaging
If set, skips building the msi's and installer
.PARAMETER DefaultsLLD
If false, use `link.exe` as the default linker with the SDK (with SPM)
.PARAMETER DebugInfo
If set, debug information will be generated for the builds.
.PARAMETER EnableCaching
If true, use `sccache` to cache the build rules.
.PARAMETER Test
An array of names of projects to run tests for.
'*' runs all tests
.PARAMETER Stage
The path to a directory where built msi's and the installer executable should be staged (for CI).
.PARAMETER BuildTo
The name of a build step after which the script should terminate.
For example: -BuildTo ToolsSupportCore
.PARAMETER ToBatch
When set, runs the script in a special mode which outputs a listing of command invocations
in batch file format instead of executing them.
.PARAMETER PinnedLayout
If "New", uses the new toolchain install layout. Otherwise, the old layout.
.EXAMPLE
PS> .\Build.ps1
.EXAMPLE
PS> .\Build.ps1 -SDKs x64 -ProductVersion 1.2.3 -Test foundation,xctest
