Invalid TableNumber error when linking static lib into a shared module

Open IsabelParedes opened this issue 9 months ago • 14 comments

Hello! I'm trying to compile some shared modules that link Flang's libFortranRuntime.a (flang source). This has been successful with versions 3.1.61 and older. However, starting with versions 3.1.62 (up to 4.0.5), there is an Invalid TableNumber error that occurs.

Version of emscripten/emsdk:

emcc (Emscripten gcc/clang-like replacement + linker emulating GNU ld) 3.1.62 (34c1aa36052b1882058f22aa1916437ba0872690)

Failing command line in full:

As this is a regression, bisecting may help find the exact commit where this regressed:

https://emscripten.org/docs/contributing/developers_guide.html#bisecting

It seems clear this is in LLVM, so actually bisecting directly there is also an option.

Can you perhaps attach the broken tst.so file?

sbc100 avatar Mar 21 '25 17:03 sbc100

Can you perhaps attach the broken tst.so file?

Here it is: tst.so.zip

IsabelParedes avatar Mar 21 '25 18:03 IsabelParedes

It looks like the shared library doesn't have any table usage, but it does have table element segment:

Elem[1]:
 - segment[0] flags=2 table=4294967295 count=3 - init global=2 <__table_base>
  - elem[0] = ref.func:37 <__cxx_global_array_dtor>
  - elem[1] = ref.func:38 <__cxx_global_array_dtor.2>
  - elem[2] = ref.func:41 <__cxx_global_array_dtor>

So I guess maybe the linker decided not to include a table at all.. resulting in -1 for the table index here.. oops.

sbc100 avatar Mar 21 '25 18:03 sbc100

Did you rebuild all of the input object and libraries that go in to tst.so.

It seems like the __indirect_function_table symbol is missing in the output, but if I'm reading the linker code correctly that can only happen if non of the input object contains a reference to __indirect_function_table. Can you attach some of the input objects or archive files? Can you try building everything from source?

sbc100 avatar Mar 21 '25 19:03 sbc100

Did you rebuild all of the input object and libraries that go in to tst.so.

Yes, I rebuilt libFortranRuntime.a from scratch.

It seems like the __indirect_function_table symbol is missing in the output, but if I'm reading the linker code correctly that can only happen if non of the input object contains a reference to __indirect_function_table. Can you attach some of the input objects or archive files?

Here is the build directory for the Fortran runtime. It has the object files, the static library, and some additional files if that helps. _build_dir_v62.zip

Can you try building everything from source?

What do you mean exactly? Build the fortran runtime from source like above? Or build emscripten from source?

I was looking into the bisecting docs mentioned. It might take me a little while to set it up.

IsabelParedes avatar Mar 21 '25 19:03 IsabelParedes

What do you mean exactly? Build the fortran runtime from source like above? Or build emscripten from source?

I mean build all your object files and libraries from source when you update emscripten. It sounds like you did that though.

sbc100 avatar Mar 21 '25 22:03 sbc100

I believe the linker should be hitting an assert in this case. Can you trying installing the -asserts version of emedk to confirm (e.g ./emsdk install 4.0.5-asserts.

sbc100 avatar Mar 21 '25 22:03 sbc100

Hi @sbc100 ! Here's the output with the 4.0.5-asserts version

I did some bisecting, this is the commit that breaks it

Could this be the problem? https://github.com/llvm/llvm-project/pull/80169

Hi! I did some more debugging and bisected LLVM. This is the PR that causes the regression: https://github.com/llvm/llvm-project/pull/93261

I was able to reproduce this, but didn't manage to figure out all the details. I has to do with some pretty subtle/complex details of if/when we include the __indirect_function_table symbol itself.
