Can't compile bdwgc for emscripten #163

Closed intrigus closed 6 years ago

intrigus commented 7 years ago

Hello, I'm trying to compile bdwgc for emscripten, but it fails during compilation. If you need more information I'm happy to provide it.

This is the error:

os_dep.c:1258:9: error: None of HEURISTIC* and *STACKBOTTOM defined!
#       error None of HEURISTIC* and *STACKBOTTOM defined!
        ^

Used versions and more information:

emcc --version

Emscripten support is added in commits 7d2905e, 4eaea0a. But it seems it was not tested on mac host. Could you please try the following fix?

Compiling works with this patch.

Linking with my code also works, but fails at runtime.

llvm_frameaddress is defined as this, but I'm not sure if it's even called at runtime because it's not in the stacktrace. (Maybe it has been inlined, don't know)

  function _llvm_frameaddress() {
  Module['printErr']('missing function: llvm_frameaddress'); abort(-1);
  }

Anyway thanks for you help :) I'm not sure if this is a bug in bdwgc or in emscripten, but if it works for Unity it should probably also work for me :)

Will open an issue in emscripten, if it's indeed a problem with emscripten. If you need anything else from I'm happy to provide it.

ivmai commented 7 years ago

Have you checked the master with the given diff or gc 7.6.0 (with the diff)?

intrigus commented 7 years ago

I have checked bdwgc 7.6.0 with the diff This compiles fine but fails at runtime. (As stated here https://github.com/ivmai/bdwgc/issues/163#issuecomment-304704885 ) Without the patch it didn't even compile.

I'm going to try bdwgc master with the diff and also emscripten master with bdwgc master.

Any other suggestions?

intrigus commented 7 years ago

Judging from the generated javascript GC_get_stack_base is not implemented in emscripten (GC_UNIMPLEMENTED = 3) that's why this line fails with an abort https://github.com/ivmai/bdwgc/blob/408ea9f873e48f6001f717b53fc0dec9a2d0f6d5/os_dep.c#L1467

function _GC_get_stack_base($0) {
 $0 = $0|0;
 var $1 = 0, label = 0, sp = 0;
 sp = STACKTOP;
 STACKTOP = STACKTOP + 16|0; if ((STACKTOP|0) >= (STACK_MAX|0)) abortStackOverflow(16|0);
 $1 = $0;
 STACKTOP = sp;
 return 3; // GC_UNIMPLEMENTED @line 1454 "os_dep.c"
}
function _GC_get_main_stack_base() {

  1. Could you also please checkout commit 7d2905e and try it?
  2. Could you also please try bdwgc master + diff above + comment out GC_stackbottom = GC_get_main_stack_base() in misc.c ?
intrigus commented 7 years ago

ad 1. 7d2905e Works fine. ad 2. Going to try now.

ivmai commented 7 years ago

Hmm. Discard 2. Could you please try 4eaea0a ? If it works then bisect starting from 4eaea0a and finishing at gc7_6_0.

juj commented 7 years ago

I recall poking a codebase that built Boehm some time earlier. Since JavaScript/asm.js/WebAssembly is not able to access the function call stack or the local data stack, it is not possible for Boehm to perform its stack walking operation to find which objects are rooted by the stack. To work around that, codebases generally only do Boehm GC steps when the stack is empty so it is known that there are no objects that would be rooted by the stack, and Boehm is compiled in a mode that disables stack walking since it does not apply.

If that is already being done, and assuming the build issue is only a technicality of appeasing the compiler to see the correct symbols, then I suppose any no-op implementation might work (i.e. return stack base = address 0, stack size = 0). Alternatively, you can try hooking the functions to the pthread_attr_getstack function (http://pubs.opengroup.org/onlinepubs/009695399/functions/pthread_attr_getstack.html) which should be functional in both singlethreaded and multithreaded builds. Though reading this stack has very different meaning than the native stack, and won't contain function local GC objects.

I made a mistake, I thought that I use version 7.6.0 but my version is much newer. Anyway I found these two issues. One is new the other one is already known. I didn't yet bisect https://github.com/ivmai/bdwgc/issues/163#issuecomment-304704885 because I don't know whether it may be solved by solving (1) or (2).

@ivmai I've bisected and found two issues.

(1) Compile error issue:

See https://gist.github.com/intrigus/ef1f0bf9f19f164611f9a1c97ac58e05#file-gistfile2-txt

(2) Another new issue I found

After applying the diff it compiles but fails at runtime with yet another error. Will have to bisect again :)

@ivmai @juj @intrigus you may wish to take a look at the discussion over here: https://github.com/WebAssembly/binaryen/issues/1312#issuecomment-351272048

It appears that we could get a workable solution for getting this going as per @kripken via binaryen for emscripten.

ivmai commented 6 years ago

Is there anything to do regarding this issue?

ylluminate commented 6 years ago

@ivmai I've had some other pressing issues that have precluded my doing anything here. Has anyone been able to get this working, and if so or otherwise, could you post your findings?

ivmai commented 6 years ago

I think all the mentioned commits are included in v7.6.4 release

ylluminate commented 6 years ago

Thanks very much @ivmai. It would be interesting to see if anyone has a blog post or a demo of this working to see the finer points as it now stands in this usecase.
