In the discussion around #116792, @rjmccall mentioned that ARCMigrate
has been obsoleted and that we could go ahead and remove it from Clang,
so this patch does just that.
This reverts commit fe82a3da36196157c0caa1ef2505186782f750d1.
This broke LLDB on MacOS due to a missing symbol during linking.
The fix has been applied in c6c08eee37bada190bd1aa4593c88a5e2c8cdaac.
Original commit message:
The terminfo dependency introduces a significant nonhermeticity into the
build. It doesn't respect `--no-undefined-version` meaning that it's not
a dependency that can be built with Clang 17+. This forces maintainers
of source-based distributions to implement patches or ignore linker
errors.
Remove it to reduce the closure size and improve portability of
LLVM-based tools. Users can still use command line arguments to toggle
color support expliticly.

The `LLDB_TEST_USE_VENDOR_PACKAGES` has defaulted to `Off` for a while.
Either installing `pexpect` or skipping those tests with
`-DLLDB_TEST_USER_ARGS=--skip-category=pexpect` seems to be enough that
we can fully remove this option.
This patch removes the `LLDB_TEST_USE_VENDOR_PACKAGES` cmake
configuration as well as the associated code to add
`third_party/Python/module` to the python path. I'll do the actual
deletion of `third_party/Python/module` in a followup PR in the
(unlikely, I hope) event this commit needs to be reverted.
We set LLVM_ENABLE_ASSERTIONS in some builds which is now translated
to LIBCXX_HARDENING_MODE=safe, but our codebase is not yet clean and
we're getting assertion failures.
This has been deprecated in favor of CMake's CMAKE_MSVC_RUNTIME_LIBRARY
in c6bd873403a8ac6538a3fe3b3c2fe39c16b146a6 .
Current release branch still contains it in deprecated status so no
existing end-users will be affected.
This flag causes the toolchain distribution to be built using LLVM
CMake's multiple distribution feature. The distribution* family of CMake
targets would be replaced with the toolchain-distribution* family.
This shouldn't otherwise affect the semantics of the build, but it sets
up the ability to split out the LLDB build from the main distribution
used by Fuchsia.

stage2-check-lldb should be run in a 2-stage build to test the final
LLDB artifact, so it and related targets must be exported to the stage 1
project.

LLVM_ENABLE_PROJECTS is automatically forwarded from stage 1 builds to
stage 2 builds, so setting FUCHSIA_ENABLE_LLDB has no effect on
two-stage builds.
Instead, add FUCHSIA_ENABLE_LLDB to the stage one build as well.
This also disables curses and libedit by default for now in both stage1
and stage 2 builds; these should be opt-in.

See the code review for details. Reverting until the problem and how to
solve it is better understood.

This reverts commit bb939931a1adb9a47a2de13c359d6a72aeb277c8.
Fuchsia already uses libunwind, but it does so implicitly via libc++.
This change makes the unwinder choice explicit.

This is the first part of a plan to ship experimental features
by default while guarding them behind a compiler flag to avoid
users accidentally depending on them. Subsequent patches will

Note that this patch intentionally does not start guarding
existing <experimental/FOO> content behind the flag, because
that would merely break users that might be relying on such

should start guarding new TSes behind the flag, and get rid

Also, this patch must jump through a few hoops like defining
_LIBCPP_ENABLE_EXPERIMENTAL because we still support compilers
