I'm encountering a build error with JIT enabled and LLVM 7.1.0 and the latest 5.2.0, on NixOS.

libinterp/parse-tree/jit-typeinfo.cc:1676:71: error: no matching function for call to 'llvm::ConstantStruct::get(llvm::StructType*&, llvm::

Gene Harvey Is there a chance you need to update the patchset? Besides this patch which failed I wasn't sure what patches should I try in order to give feedback. Should I take all of them besides jitfix.patch?

OK, maybe I don't understand well enough the basics of how the JIT compiler is supposed to work, so let's try to fix that problem first...

I was thinking that the JIT compiler worked on functions, but now I see it also works on loops, independent of function bodies.  For loops, it could use the current scope and stack frame to see whether a variable has been flagged as global or persistent.

If compiling a complete function, I'm not sure how that would work since at the beginning of a function evaluation the status of variables (global or persistent) is not known unless global and persistent are handled as parse-time declarations instead of executable statements as they are now.  It seems to me that to properly handle global and persistent with the JIT compiler we will need additional support from the parser and a change in the way that global and persistent declarations work.  Given recent changes in Matlab diagnostics for global and persistent declarations, it appears Matlab is also heading in that direction.

Mon 08 Jul 2019 11:21:42 PM UTC, comment #18: 

The JIT evaluator doesn't manipulate the outer stack, so the dispatching frame should correspond to the current frame when is_global and is_persistent are called. So, at least at the top level of scope in the JIT, those calls should work in the same as if they were interpreted right? It would probably make sense to maintain a reference to the current frame rather than rely on the current frame in the tree_evaluator.

Gene Harvey <gharveymn>
Mon 08 Jul 2019 07:57:46 PM UTC, comment #17: 

Global and persistent attributes for variables are still handled as run-time things in the interpreter, but for JIT compiling, I think we need to handle them as declarations that happen when the function is parsed.

I'm not sure how best to do this job currently, but the way the new is_global and is_persistent functions are used doesn't look right to me.  When those are called, does the current scope correspond to the function that is being compiled?  If so, does that match the current stack frame?

Probably the same problem. Here's the build error:

This is different than the one I'm referring to, but the principle is still there---libLLVM-8 used by Qt is trying to use libLLVM-3.7.1.

What kind of problem do you run into when doing a full build with older version of LLVM ?

I recall that I had to build without the doc in some cases, are you referring to the same problem ?

Julien Bect <jbect>
Mon 08 Jul 2019 04:33:53 PM UTC, comment #14: 

@Julien Sorry about the wait, it turned out to be a bit more convoluted than expected. I've attached a couple changesets which should fix the behavior described.

fixincludes.patch: This adds HAVE_ macros to surround the includes. I had to define a new m4 macro which checks the exact location of a header to prevent shadowing from system headers. It really isn't the most lovely of solutions, but it seems to work.

Honestly, I'm not sure if I'm wasting my time hacking on that configuration code; I just don't understand how we intend to ship like this? If we did then we're locking down our users to one version of LLVM, and the fact that we also link to Qt5 (which uses LLVM-8) in libinterp will cause problems. I can't even do a full build when building with older versions of LLVM because for some reason the Qt code will include headers from that older version rather than LLVM-8, and this causes segfaults in the Qt code.

I really think we should just provide a jit_ir interface which dldfcns can hook into, the dldfcns will provide the translation to a single version of LLVM each. No convoluted configuration needed.

oldcrash.patch: This fixes the `LLVM_ERROR: ` crash. It turns out that it was an "Error: success" error from LLVM. I believe it was caused by the fact that we didn't declare functions in modules which they were used, but not defined. This is tested on LLVM debug builds of versions 3.7.1, 3.9.1, 4.0.1, 5.0.2, 6.0.1, 7.1.0, and 9.0.0svn, and then 8.0.0 release of course, all running on Arch x64.

(file #47170, file #47171)

OK, I'll take a look at it.  It would be good to be able to build with the JIT compiler enabled.  We are currently building LLVM 6 for the llvmpipe OpenGL renderer for the Windows binaries.  I don't know whether there are specific requirements that force us to use version 6 for Mesa OpenGL, so maybe we could also use LLVM 8 for that?

@Gene: Concerning the autoconf issue  (comments #7, #8 and #9), are you going to fix it or do you want me to do it ?

@John, @Rik: The patch proposed by Gene makes it possible to build with --enable-jit on LLVM 8 and 9, and solves several open issues (see comment #5 and following).  I suggest to consider it for default.

Julien Bect <jbect>
Wed 26 Jun 2019 01:08:25 PM UTC, comment #11: 

Same configuration as in comment #5, this time with LLVM 9 (from Debian experimental).

Result: OK, same as LLVM 8.

Wed 26 Jun 2019 08:42:22 AM UTC, comment #10: 

Concerning the crash with LLVM 7: four unit tests are actually crashing Octave (the one reported below and three others).

All of them are related to testing indexing with parentheses.

Perhaps something to do with your changes to octave_jit_paren_scalar ?

Julien Bect <jbect>
Wed 26 Jun 2019 06:51:35 AM UTC, comment #9: 

Following up on comments #6 and #7: the function that you are looking for appears to be located in llvm/Transforms/Scalar.h in LLVM < 7.

Julien Bect <jbect>
Wed 26 Jun 2019 12:08:17 AM UTC, comment #8: 

Hey Julien, thanks for the feedback.

Comment #6: I just tried it with 7.0; same error. I also saw the same thing happening with 5.0. It seems to occur when calling llvm::getFunctionAddress (which occurs in jit_module::getFunctionAddress if you want to set a breakpoint). It's kind of ridiculous that LLVM calls `exit 1` after giving us no information. I, or someone smarter than me, might want to build from source to step through and see what the problem is.

Comment #7: I'm having some trouble compiling with 6.0 (some weird sigsegv when processing the eps files---probably on my end), but it's needed for llvm::createPromoteMemoryToRegisterPass in newer versions. I think the include was shadowed by my system include, so I neglected to autoconf it. I'm busy tonight, but I'll see if I can do that tomorrow.

I just want to add here that I'm currently working on a rework of the system. One of my primary goals is to decouple LLVM from the current codebase and link it through DEFUNs. Translation to LLVM IR can be done by a jit_ir visitor in the linked library instead of infecting the rest of the system. Dynamically linking the backend also allows us to support multiple versions of LLVM, and possibly other JITs like GNU JIT. I'm shooting for completion by the end of the summer, but I can't give any guarantees on that.

I'll also note that I'm finding the current jit_ir system difficult to debug and understand with all the templated internal lists and lack of documentation. The rework should provide a simpler system so we can hook in static analyzers (like use-before-def, which we can reflect in the editor).

Gene Harvey <gharveymn>
Tue 25 Jun 2019 06:35:53 PM UTC, comment #7: 

Same configuration as in comment #5, but with LLVM 6.0.

This time build fails:

  CXX      libinterp/parse-tree/libparse_tree_la-pt-jit.lo
libinterp/parse-tree/pt-jit.cc:127:10: fatal error: llvm/Transforms/Utils.h: No such file or directory
#include <llvm/Transforms/Utils.h>
compilation terminated.

It seems that Utils.h does not exist in LLVM < 7, what is it needed for?

Julien Bect <jbect>
Tue 25 Jun 2019 12:48:00 PM UTC, comment #6: 

Same configuration as in comment #5, but with LLVM 7.0.

Build succeeds but jit.tst crashes octave:

***** testif HAVE_LLVM
jit_failcnt (0);
ndim = 100;
result = 0;
m = zeros (ndim);
m(:) = 1:ndim^2;
i = 1;
while (i <= ndim)
   for j = 1:ndim
     result = result + m(i, j);
   i = i + 1;
assert (result == sum (sum (m)));
assert (jit_failcnt, 0);

@Gene: Have you seen something similar with LLVM 7.0 ?

Julien Bect <jbect>
Tue 25 Jun 2019 07:19:44 AM UTC, comment #5: 

I have built Octave default (30f53f7a7293184f38b832a6494901636f5f2015) with the four patches applied, on Debian unstable with LLVM 8.0.


1) The build succeeds and here is the result of make check:

                                                    (reported bug) XFAIL   2
fixed/jit.tst .................................................. PASS   36/38 

  PASS                            15604
  FAIL                                1
  XFAIL (reported bug)               27
  SKIP (missing feature)              9
  SKIP (run-time condition)          34

So, this patch fixes bug #55809: "Building with --enable-jit fails since the recent variable storage refactoring".


2) The following snippet from bug #55492, comment #2, no longer crashes octave:

jit_enable (1)
m = [1 2; 3 4];
while (1)
  z = m(1, 2);

The original bug report was for LLVM 4.0, which I haven't tested yet, but apart from that I would that this patch fixes bug #55492 too.


3) The following snippet from bug #55469, comment #2, no longer crashes octave:

jit_enable (true);
jit_startcnt (5);

x = 1 + 1i;
for j = 1:5
    x = x + 1;

So, it appears that this patch also fixes bug #55469 ;-)


4) Also, the following snippet from bug #53691 no longer crashes octave:

jit_enable (1)
f = inline ("x^2 + 2");

So, it appears that this patch fixes bug #53691 too !


Summary: this patch makes it possible to build Octave with LLVM 8 and solves four open issues.

I haven't carried out a detailed code review, nor will I have time to do it in the near future, but from an "external" point of view I would vote for pushing this to default.

Julien Bect <jbect>
Tue 04 Jun 2019 09:21:26 PM UTC, comment #4: 

Alright, I've split the patch into four components and removed all the extraneous stuff. Hopefully it's more digestible now.


  • jitconfigure.patch: A fix for builds breaking on some systems because of the use of -isystem.
  • jitbuild.patch: Updates to work with LLVM-8.0 and the stack_frame refactor (bug #55809).
  • jitbug55492.patch: A fix for bug #55492. This is meant to be temporary.
  • jitsinfail.patch: A temporary workaround for a segmentation fault that occurs when calling `sin` with the JIT.

My fault, I left a lot of changes in that weren’t strictly necessary. I can definitely repackage it if people aren’t too far through yet.

With regards to the std::endl changes, it’s just premature optimization (std::endl flushes the buffer). So not really needed.

Gene Harvey <gharveymn>
Sun 02 Jun 2019 10:48:36 PM UTC, comment #2: 

Also, afaict, this patch is still using the C++ interface to LLVM. That is unstable and they suggest we use the C interface instead. It became unsustainable to keep up with the C++ API changes to LLVM, so I think any attempt to revive Octave's JIT should be focussed on moving to LLVM's C API or to any other JIT library (e.g. libgccjit, GNU lightning or whatever else).

There seem to be a lot of unrelated changes here, what's the point of changing `os << std::endl;` to `os << '\n'`?

This patch is also kind of mammoth which makes it difficult to review. Think you could split it up?

This patch resolves bug #55492 and bug #55809, and some other unlisted bugs. It also adds support for versions of LLVM up to and including LLVM-8.0. However, LLVM-5.0 seems to error in llvm::getFunctionAddress with empty string output to stderr and then calls `exit 1`. So if the patch gets accepted, I'll put that on the bug tracker.

Unlisted bugs fixed:

  • The build breaks on some systems if the LLVM include directory is /usr/include because when we use -isystem it reorders the search path.
  • Build error from incorrect signature for llvm::WriteBitcodeToFile.
  • Octave crashes when the JIT tries to call `sin` (although, I'm still not totally sure what's wrong there).
