Looks good!
Oct 13 2020
Abandoned in favor of https://reviews.llvm.org/D89290 .
Oct 12 2020
Either patch works for me. Yours is shorter :-).
LGTM; thanks for fixing this!
I've finished addressing the review comments, so this is now ready for review again.
Sep 30 2020
Address review feedback.
Thanks! Description updated, fixes applied, and landed in https://reviews.llvm.org/rG6cd8511e5932
Friendly ping!

Ah, it seems the reason I didn't see this is that I wasn't using -flax-vector-conversions=none. Thanks for fixing this!

I've now opened https://github.com/WebAssembly/wasi-sdk/pull/151/ to remove the --no-threads from wasi-sdk, which was a workaround for an old bug that has long been fixed.
Aug 3 2020
- Update clang/test/CodeGen/builtins-wasm.c.
Aug 2 2020
- Reorganize the code a little so that we don't have to call mark multiple times.
- Fix a bug where we weren't considering calls from constructors as keeping other constructors live.
- Add a few more tests.

- Rename -emscripten-pic to -experimental-pic
- Change the warning text to say "not stable" rather than "not yet implemented"
Jun 16 2020
This change looks fine to me, though if you wanted to minimize the amount of code being emitted by the linker, another option would be to look into whether LLVM's FixFunctionBitcasts could handle this -- there should be a bitcast in the llvm.global_ctors array.

Landed in 66042959590d6db9d2a12803a16476d4e3508f3f.
- Address review feedback
- Mark callCtors live in the MarkLive pass rather than in the Writer pass.
Run clang-format and fix lint warnings.
Use the return value of handleUndefined instead of doing a separate lookup, which avoids a redundant lookup and handles LazySymbols properly.

I apologize again for the major delay. I've now updated the patch and addressed all of your comments.
- Add tests for redeclaration behavior
- Remove disabled tests (previously marked with FIXMEs)
- Made the mismatch warning more informative.

Looks good to me.

This addresses the review feedback from earlier. To answer this question:
Rebase, update, add a test, and add basic error reporting.
Apr 11 2020
Looks good! I don't have anything to add beyond Thomas' review comments.

Is looks possible that the test failure was due to an unrelated commit 210f40fe9a30212396311d265904b2d73859c53d. If so, it's possible it's fixed as of 74ab5d98d07f0b0226f45ccca8df6a450d52fb7b.

On some 32-bit x86 hosts, particularly those that use x87 arithmetic, loading and storing with floating-point types can change the NaN bit pattern. To preserve the bit pattern reliably, MCOperand should represent floating-point immediates by representing the bits in int32_t for 32-bit and int64_t for 64-bit. Codegen and MC don't usually look at the value, but where they do need to interpret it as a floating-point value, they can reinterpret the bits on demand.

Cool, LGTM, with optional suggestion for signed char below:

Very cool, thanks for putting this together!

Instead of creating a new LLVM-IR-level attribute here, could you have clang translate the attribute to "wasm-export-name", to keep the LLVM-IR level simpler?
Mar 18 2020
The commit description says "not ordered to group destructors with common associated objects" but it looks this patch is doing grouping by associated object. Is that intentional?
- Add a comment.
- Add a test of two destructors with different priorities and the same associated object.
Feb 19 2020
Looks good, with the clang-format lint fixed :-).
LGTM!

Address review feedback.
I apologize for the extraordinary delays here; at long last, I've now addressed your feedback.

To support a transition to the new system, temporarily define a __main_void alias for no-argument main. This allows libc to detect whether it's calling old-style or new-style main and do the right thing.
Dec 17 2019
This updates the main vs __main_argc_argv patch so that it doesn't apply to Emscripten targets, following the discussion in https://github.com/WebAssembly/tool-conventions/pull/134.

I've done some more experimenting with this, and it turns out not to work very well, because calls to these functions get generated after LTO runs, so I'll abandon this.
Nov 25 2019
I've now posted https://reviews.llvm.org/D70677 which should fix the test failure when LLVM_APPEND_VC_REV=NO is set.

Do you think that setting this attribute should also prevent GC?
It appears this doesn't handle exporting an imported function yet, which is fine for now, but it would be good to issue a warning, because wasm itself is capable of representing this:
void aaa(void) __attribute__((import_module("imp"), import_name("foo"), export_name("bar")));
Don't run wasm-opt with -O0.
Use PATH instead of WASM_OPT to find wasm-opt.
Sep 21 2019
This kind of thing ought to have helped code like
extern int A[];

Would it be better to do this check in LLVM, in the backend, with a report_fatal_error?
