Nice, that's a lot of code cleaned up! LGTM, but probably should wait for someone from Apple to weigh in. I think the new formatting for those error messages is better for them too but that's not my call :)

Odd. Thanks for confirming. We'll revert while we try to figure out what it is in that builders config that is uncovering the bug. I don't think the default config uses libc++, so probably that?

I guess testing is getting more complicated.
Maybe we should separate tests and non-test patches here? I suspect we well have several of them. Even after lit will run them as expected, they will likely just crash on start.

I think this is probably fine from the NDK perspective. Even before Clang defaulted to C++11 or newer, our build system did that when using libc++. Other build systems may not have, but unfortunately I'm not currently able to get at the data to get a concrete answer.

danalbert added a comment to D102570: [ELF] Add -Bsymbolic-non-weak-functions.

Do you plan to land this? I thought of it as potentially useful for https://github.com/android/ndk/issues/1551. The issue has the full details, but the summary is that we only want a single copy of __emutls_get_address that's used by all shared objects in a process, otherwise different DSOs will see different emulated TLS state for the same variable. One way to ensure that would be to put the emulated TLS bits in their own DSO and have everyone else reference that, but a full DSO is pretty heavy-weight. Another would be to make it default visibility and weak and let the dynamic linker coalesce multiple copies at runtime; -Bsymbolic and -Bsymbolic-functions would break that, but -Bsymbolic-non-weak-functions wouldn't.

I was waiting for users:) Glad that this can find a user.

danalbert updated the diff for D77657: [WIP][libc++] Add an executor that bundles tests for deferred execution.

Initial pass at my suggestion of deferring XFAIL handling to the bundler. This is incomplete because we'll need to differentiate XFAIL-BUILD and XFAIL-RUN in tests (running this as-is makes any test that is XFAIL because it doesn't _build_ turn to FAIL, but things that fail to _run_ are handled correctly), but it's enough to get feedback on the idea.

May 4 2021

danalbert added a comment to D77657: [WIP][libc++] Add an executor that bundles tests for deferred execution.

Re problems 1 and 2 (xfail handling), my idea what that we'd add --xfail to the bundler interface and delegate to the test runner to handle that. For Android I need to fit these tests into tradefed, so our bundler would work by creating the test config files for tradefed and would let it handle xfails. We don't have much reason to interact with LIT again after the tests are built. This more or less matches how we've been running libc++ tests for years, though with some improvements (xfail info is currently manually tracked rather than being given by LIT). I've been carrying a local patch that adds a --build-only flag which just ignores xfail annotations and defers all the execution and interpretation to our test runner.

danalbert added a comment to D91841: [builtins] Define fmax and scalbn inline.

Implementing the relevant functions called by divxc3 is one choice, another choice is to emulate libgcc - don't use scalbn.

The libgcc version goes about the computation in a slightly different way -- e.g. it computes an intermediate ratio of c / d or d / c (ensuring that the fabs(ratio) is at most 1.0) to avoid overflow, whereas the current compiler-rt version uses scalbn (and closely matches the reference implementation in Annex G of the C specification). The scalbn approach seems to be more accurate? e.g.:

  • From G.5.1 Multiplicative operators (paragraph 9):

Scaling the denominator alleviates the main overflow and underflow problem, which is more serious than for multiplication.
In the spirit of the multiplication example above, this code does not defend against overflow and underflow in the calculation
of the numerator. Scaling with the scalbn function, instead of with division, provides better roundoff characteristics.

/* ??? We can get better behavior from logarithmic scaling instead of
   the division.  But that would mean starting to link libgcc against
   libm.  We could implement something akin to ldexp/frexp as gcc builtins
   fairly easily...  */

I'm guessing we wouldn't want to reduce accuracy to break the libm dependency?

We've since added -fuse-ld=lld to the three CMAKE_*_FLAGS so I think we're likely set on our end.

https://reviews.llvm.org/D76452 not being accepted means that Android toolchains must have LLD installed as ld.

If you pass -fuse-ld=lld everwhere, that's not needed, right (?)

Landed revert in 1608ba09462d877111230e9461b895f696f8fcb1. Someone should file a PR to make sure that gets merged to the 12.0 branch.

We can then reland on trunk once there are clear instructions for folks building with trunk clang but old NDK but without the toolchain file (either "use toolchain file" or "set LLVM_USE_LLD" or something like that, I'm guessing?)

While this doesn't look wrong to me -- and the correctness of this depends entirely on where vendors decide to put their headers so it's hard for me to verify -- I'm wondering why not all toolchains use this mechanism. We seem to be adding an abstraction that's used only by some toolchains, but not all. I think it would be great to have a single canonical way of representing the system root.

danalbert reclaimed D76452: Use LLD by default for Android..

It seems I'd goofed something in my testing earlier (I think I still had -fuse-ld=lld force on in my build system). While Clang will find ld in the driver directory and prefer it, LLD defaults to the Darwin driver mode when argv[0] is ld when run on Darwin. We need GNU mode, and the best way to get this behavior is to have Clang invoke ld.lld instead.
