This directory should be excluded during installation since the content is only
used for local development. swiftsourceinfo file is currently emitted to this directory.
Two places in Driver are creating temporary files at a point in the
process where failure is not expected. We should do something better
about this, but meanwhile harmonize their failures and include a
little more info.
Filed https://bugs.swift.org/browse/SR-11541 to improve this.
Add `-no-toolchain-stdlib-rpath` flag: the negative version of
`-toolchain-stdlib-rpath`.
Make `-no-toolchain-stdlib-rpath` be the default: use `/usr/lib/swift` as
default RPATH on Darwin platforms instead of toolchain standard library.
Adapted from https://github.com/apple/swift/pull/27206.
tensorflow branch requires the opposite default (use toolchain standard
library as RPATH) because some stdlib modules like TensorFlow do not exist in
`/usr/lib/swift`.
This commit introduces a CMake target for each component, adds install targets
for them, and switches build-script-impl to use the target `install-components`
for installation. Each of the targets for each component depends on each
of the individual targets and outputs that are associated with the
corresponding swift-component.
This is equivalent to what already exists, because right now install rules are
only generated for components that we want to install. Therefore, this commit
should be an NFC.
This is a resubmission (with modifications) of an earlier change. I originally
committed this but there were problems with some installation rules.
Now that we've moved to C++14, we no longer need the llvm::make_unique
implementation from STLExtras.h. This patch is a mechanical replacement
of (hopefully) all the llvm::make_unique instances in the swift repo.
On targets which support COMDAT (PE/COFF, ELF), use that to relax the
constraints on the emission of `-force-autolink-symbol` so that it is
possible to use that with `-incremental`.

This flag adds diagnostic names to the end of their messages, e.g. 'error: cannot convert value of type '[Any]' to specified type '[Int]' [cannot_convert_initializer_value]'. It's intended to be used for debugging purposes when working on the compiler.
Currently we only support building for android armv7, arm64, x86,
x86_64. In the future, if support for MIPS and MIPS64 is added, we
should normalise those as well. This is needed to support compilation
against modern NDKs.
The backwards-deployment install name trickery we're using doesn't
handle "patch" components in version numbers, so we still need to
provide an rpath even when deploying to macOS 10.14.4.
Use `clang` rather than `clang++` as the linker driver. This ensures
that we do not force a C++ runtime on the general code. This is fine
for now as C++ interop is not yet available for Swift. This prevents
the accidental mix-and-match of various C++ runtimes. This can cause
problems on platforms like android where `libstdc++` is an unsupported
runtime but is generally the default for Linux platforms.
The option -enable-anonymous-context-mangled-names prevents stripping of dead metadata to improve debuggability.
But with optimizations enabled, we do a lot of dead code stripping which affects debuggability anyway.
