@thanm , @cherrymui : you can find my compressed build folder in https://drive.google.com/file/d/1kLsAR8cXKOX0nBqNy3DExNCz4maK-coU/view?usp=sharing

advancedwebdeveloper commented 3 years ago

I was able to compile libgmp and install it locally. Then I have compiled and installed libffi locally. Something is wrong with CMake's config - it is triggering the generation of libgmp's configuration in a wrong way. Thus non-working Makefile is produced.

thanm commented 3 years ago

@advancedwebdeveloper randomly mentioning folks as you did above is not helpful, just generates noise and confusion.

As of 33d28e1b8583e3e0455d80bc5bec05476257c39c gollvm is no longer invoking the external assembler by default, so the version of "as" should not be relevant. I would suggest updating your git clients and redoing the build from a clean slate.

What exactly are you proposing? The question was about libffi, probably - it is not compiling. And it is about building gollvm's dependency - and it is surely about invoking GNU as.

And why did you decide that I have an outdated Git client?

$ git version git version 2.25.1

Not the version of git itself, the revision checked out in each repo. Example:

$ cd [your llvm project root]/llvm/tools/gollvm $ git log --oneline -1 33d28e1 (HEAD -> master, origin/master, origin/HEAD) gollvm: support debug compression options for integ assembler $ git -C libgo/libffi log --oneline -1 407394c (HEAD -> master, origin/master, origin/HEAD) docs: fix simple typo, paramters -> parameters (#589) $ git -C gofrontend log --oneline -1 3b6252d2 (HEAD -> master, origin/master, origin/HEAD) compiler: don't export function type parameter names

advancedwebdeveloper commented 3 years ago

Here is what I see:

~/workarea/llvm-project/llvm/tools/gollvm$ git log --oneline -1 33d28e1 (HEAD -> master, origin/master, origin/HEAD) gollvm: support debug compression options for integ assembler

~/workarea/llvm-project/llvm/tools/gollvm$ git -C libgo/libffi log --oneline -1 407394c (HEAD -> master, origin/master, origin/HEAD) docs: fix simple typo, paramters -> parameters (#589)

thanm commented 3 years ago

OK, try rerunning the compile command for that file with -E (and with -MT/-MD etc stripped out). This will show the preprocessed source. Ex:

Well, I'm stumped then. What you are telling me is that when you rerun the offending command by hand, it works. But when ninja runs it, you get the

home/oceanfish81/workarea/llvm-project/llvm/tools/gollvm/libgo/libffi/src/x86/unix64.S:36:2: error: expected identifier or '('

errors. I don't have an explanation for that.

advancedwebdeveloper commented 3 years ago

@thanm , here are my compressed llmv-project + build_release folders

thanm commented 3 years ago

OK, I should have picked up on this before, but the command that's being used to assemble the libffi files includes these options mixed in with all the others:

-x c

That tells clang that in spite of the ".S" extension on the file, the input language is C, not assembly.

So the next question is how that "-x c" got in there. I looked for it in the LLVM sources-- don't see it anywhere there. How exactly are you running cmake, e.g. exact cmake invocation?

advancedwebdeveloper commented 3 years ago

I have pulled the source tarballs of all four dependencies - and configured/built/installed those, in external/separate folders. You can check the proof (compressed build folders here) .

It still does not explain how to avoid locking Ninja's (or make's) targets - I can't compile/link the rest, cause of this (and I can't re-use pre-installed decencies - headers and libs are available from system folders). Patching CMake's config. files would be required.

As for your question: I didn't experiment with libc++, this time - so I tried such configurations:

-DCMAKE_C_COMPILER=clang -DCMAKE_CXX_COMPILER=clang++ -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=~/gollvm_dist -G Ninja ../llvm-project/llvm

-DCMAKE_C_COMPILER=clang -DCMAKE_CXX_COMPILER=clang++ -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=~/gollvm_dist -DLLVM_TARGETS_TO_BUILD=X86 -G Ninja ../llvm-project/llvm

Maybe -DLLVM_TARGETS_TO_BUILD=X86 triggers something - but it was just to limit against non-desired back-ends.

Let me know what else should I check.

thanm commented 3 years ago

You might try adding -DCMAKE_ASM_COMPILER=clang to your cmake invocation. Shot in the dark, but it might help.

-DLLVM_TARGETS_TO_BUILD=X86 should be fine, I use that routinely.

advancedwebdeveloper commented 3 years ago

make -j4 gollvm

Please add "-G ninja" when invoking cmake. Building with "make" is not something I've ever tried-- please use ninja instead.

advancedwebdeveloper commented 3 years ago

This corresponds to what I got with

$ cmake -DCMAKE_ASM_COMPILER=clang -DLLVM_TARGETS_TO_BUILD=X86 -DCMAKE_C_COMPILER=clang -DCMAKE_CXX_COMPILER=clang++ -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=~/gollvm_dist -G Ninja ../llvm-project/llvm

thanm commented 3 years ago

OK, try running cmake with the additional "--trace-expand" option. This will generate huge amounts of trace output, but once you have that you can sift through it and look for the spot where the "-x c" is being introduced.

advancedwebdeveloper commented 3 years ago

My log Compressed build folder

Log is too big for any gist or download threw Github's UI.

advancedwebdeveloper commented 3 years ago

What should be the next step?

thanm commented 3 years ago

OK, I in inspected the cmake error log -- nothing there. That suggests that the bad behavior is being injected by cmake itself.

On that theory I found this commit:

https://github.com/Kitware/CMake/commit/644d3b86ebb4be108172765e96251162e2537344

which looks very suspicious. What version of cmake are you runnning? Is it 3.18 or beyond by any chance?

I will try building a tip version of cmake to see if I can reproduce.

Change https://golang.org/cl/264633 mentions this issue: gollvm: fix libffi compiler config to be compatible with cmake

thanm commented 3 years ago

It does indeed reproduce. I am sending a fix.

ianlancetaylor commented 3 years ago

Just a note that I fixed the libbacktrace warnings reported above. These are not causing any trouble, but it seemed worth fixing them.

thanm commented 3 years ago

https://golang.org/cl/264633 has been submitted.

@advancedwebdeveloper thanks for your patience.

This should be fixed now, let me know if not.

advancedwebdeveloper commented 3 years ago

@thanm, and what is the problem with upgrading ../llvm-project/llvm/tools/CMakeLists.txt ? So it would target the latest versions of gmp, mpfr and mpc libraries? That issue with MD5 becomes really annoying - my build crashes, cause of this. I had to replace those hashes by hand.

advancedwebdeveloper commented 3 years ago

I have compiled gollvm - so this issue could be closed.

But I have another issue, now: Despite

$ git -C gofrontend log --oneline -1 28f3df46 (HEAD -> master, origin/master, origin/HEAD) net/http/cgi: merge upstream changes to default env vars

and the fact that Golang 1.15.3 was released - I am getting

$ ./go version go version go1.15.2 gollvm LLVM 12.0.0git linux/amd64

. @ianlancetaylor , it looks like it is untrue cause of two reasons:

that's an up-to-date version the front-end (the last commit took place on Fri Oct 23 23:55:09 2020 - and it's Sun Oct 24 20:29:05 2020 now);
LLVM's version equals 11.0.0

ianlancetaylor commented 3 years ago

We haven't yet updated the gofrontend code to 1.15.3.

advancedwebdeveloper commented 3 years ago

But what released then?

advancedwebdeveloper commented 3 years ago

* LLVM's version equals [11.0.0](https://github.com/llvm/llvm-project/releases/tag/llvmorg-11.0.0)

@lattner , could you elaborate regarding this?

ianlancetaylor commented 3 years ago

Please, please, please, do not CC random people to ask questions about GoLLVM. Please be respectful of people's time.

The main Go compiler, the gc compiler, had a 1.15.3 release. That release has not yet been incorporated into the gofrontend code used by GoLLVM.

advancedwebdeveloper commented 3 years ago

OK, that means that there is no issue. Probably I would share the "release" build (as also as the "debug" build and other types), during the next two days. @ianlancetaylor , it would to have a summary of those not-yet-implemented features.

thanm commented 3 years ago

$ ./go version go version go1.15.2 gollvm LLVM 12.0.0git linux/amd64

This is expected behavior. When LLVM folks release version X, they then bump the major version of LLVM in trunk to N+1. See for example https://github.com/llvm/llvm-project/blob/7ab7b979d29e/llvm/CMakeLists.txt
