Ping @petrhosek @vitalybuka. I would like to merge this patch this week. CI seems to be happy, but your CI may be doing something different since IIRC this patch upset your bots the last time I tried landing it. Can you take it for a round to see if that's still the case? |

@petrhosek @vitalybuka Gentle ping. If the CI is green, I will land this next week unless someone objects to it. I don't want to purposefully break anyone's build, but I also don't want to hold off on this change forever if there's nothing actionable. Last time in https://reviews.llvm.org/D134221#3853050, @petrhosek you said:

I can not reproduce linux bot issue with the patch.
However, mark them as EXCLUDE_FROM_ALL when we don't want to build them. Simply declaring the targets should be of no harm, and it allows other projects to mention these targets regardless of whether they end up being built or not. This patch basically moves the definition of e.g. cxx_shared out of the `if (LIBCXX_ENABLE_SHARED)` and instead marks it as EXCLUDE_FROM_ALL conditionally on whether LIBCXX_ENABLE_SHARED is passed. It then does the same for libunwind and libc++abi targets. This is a reapplication of 79ee034, which was reverted in a353909 because it broke the TSAN and the Fuchsia builds.

Hi, I think we're seeing a bunch of ASAN test failures both on Aarch64 and x86_64 Linux bots. It seems like these tests are now failing to find the right shared library.

Also, this is another reminder that we would benefit from having Fuchsia builders in the pre-commit CI. We've asked before and we'll keep asking until we get them: Fuchsia is amongst the last platform that frequently reports errors but doesn't provide us with any pre-commit visibility. |

After #80007 Fuchsia builds are now always building cxx_shared for arm64 and x64 Linux. Ultimately, this is because the LIBCXX_ENABLE_SHARED is not used in compiler-rt to select the correct libc++ target, and because cxx_shared is now always defined, it is selected as a dependency when building runtimes tests. --------- Co-authored-by: Petr Hosek <[email protected]>
This is a dependency of llvm#80007.
…#80007) This patch always defines the cxx_shared, cxx_static & other top-level targets. However, they are marked as EXCLUDE_FROM_ALL when we don't want to build them. Simply declaring the targets should be of no harm, and it allows other projects to mention these targets regardless of whether they end up being built or not. This patch basically moves the definition of e.g. cxx_shared out of the `if (LIBCXX_ENABLE_SHARED)` and instead marks it as EXCLUDE_FROM_ALL conditionally on whether LIBCXX_ENABLE_SHARED is passed. It then does the same for libunwind and libc++abi targets. I purposefully avoided to reformat the files (which now has inconsistent indentation) because I wanted to keep the diff minimal, and I know this is an area of the code where folks may have downstream diffs. I will re-indent the code separately once this patch lands. This is a reapplication of 79ee034, which was reverted in a353909 because it broke the TSAN and the Fuchsia builds.

This is a purely mechanical commit for fixing the indentation of the runtimes' CMakeLists files after llvm#80007. That PR didn't update the indentation in order to make the diff easier to review and for merge conflicts to be easier to resolve (for downstream changes). This doesn't change any code, it only reindents it.
…2257) After llvm#80007 Fuchsia builds are now always building cxx_shared for arm64 and x64 Linux. Ultimately, this is because the LIBCXX_ENABLE_SHARED is not used in compiler-rt to select the correct libc++ target, and because cxx_shared is now always defined, it is selected as a dependency when building runtimes tests. --------- Co-authored-by: Petr Hosek <[email protected]>

This patch always defines the cxx_shared, cxx_static & other top-level targets. However, they are marked as EXCLUDE_FROM_ALL when we don't want to build them. Simply declaring the targets should be of no harm, and it allows other projects to mention these targets regardless of whether they end up being built or not.
This patch basically moves the definition of e.g. cxx_shared out of the
if (LIBCXX_ENABLE_SHARED)
and instead marks it as EXCLUDE_FROM_ALL conditionally on whether LIBCXX_ENABLE_SHARED is passed. It then does the same for libunwind and libc++abi targets.
