@kishorepolepalli do you see some additional output right before the assertion? It should be something with a OP_ prefix.

Depending how long it takes to reproduce, you can try to run mono -v -v -v -v (warning, extra spammy, pipe output to a file). Even better would be a reproducer.

r4_conv_to_r8 R47 <- R44 *Assertion: should not be reached at decompose.c:1889

lewurm · 2019-01-22T08:39:31Z

Thanks @kishorepolepalli!

So let me break this down:

$ ag r4_conv_to_r8
mono/mini/mini-ops.h
531:MINI_OP(OP_RCONV_TO_R8,"r4_conv_to_r8", FREG, FREG, NONE)

We are looking for OP_RCONV_TO_R8. Let's first have a look where the assertion in the JIT pipeline happens:

mono/mono/mini/mini.c

Lines 3675 to 3678 in a7cfa88

    
           #ifdef MONO_ARCH_SOFT_FLOAT_FALLBACK 
        
           	if (COMPILE_SOFT_FLOAT (cfg)) 
        
           		mono_decompose_soft_float (cfg); 
        
           #endif

decompose is right to complain about it, since ARM9 is a target that uses soft float and decompose have to make sure that no instruction is left with a floating point operation. However, OP_RCONV_TO_R8 should be handled much earlier by

mono/mono/mini/mini.c

Lines 3515 to 3518 in a7cfa88

    
           if (cfg->has_emulated_ops) { 
        
           	MONO_TIME_TRACK (mono_jit_stats.jit_local_emulate_ops, mono_local_emulate_ops (cfg)); 
        
           	mono_cfg_dump_ir (cfg, "local_emulate_ops"); 
        
           }

as OP_RCONV_TO_R8 is registered as an opcode emulation:

mono/mono/mini/mini-runtime.c

Line 4512 in a7cfa88

    
           register_opcode_emulation (OP_RCONV_TO_U8, "__emul_rconv_to_u8", "ulong float", mono_rconv_u8, "mono_rconv_u8", FALSE);

Something is wrong here. Some more questions:

How did you obtain mono?
- From some repository? If yes, which one?
- Or did you build it yourself? If so, how? Could you put up a copy of config.h somewhere?
please post the output of cat /proc/cpuinfo
please post the output of cat /etc/issue

Hello

I've come across this running Mono on ARMv5 based machines with all releases following 5.12.0.301. I had to revisit the project and decided to see how 5.18.0.240 behaved.

@solabc16 could you run

and post the output here please?

Also, where can I found how this 5.18.0.240 mono is built?

solabc16 · 2019-01-30T22:53:51Z

Hello @lewurm

Please find the output from the above below, this version of Mono (5.18.0.240) has been built with GCC 5.5 and 6.5; both producing the same results.

The configure used for the build was as follows:-

./configure                                           \
    --prefix=/local/development/path  \
    --with-mcs-docs=no                       \
    --disable-boehm                             \
    --disable-libraries                            \
    --with-static_mono=yes                  \
    --with-shared_mono=no                \
    --with-ikvm-native=no                   \
    --with-jemalloc=no                        \
    --with-jemalloc_always=no

Do let me know if you need any further information.

lewurm · 2019-01-31T14:24:00Z

Thanks @solabc16, this was useful. Some months ago we turned on -O=float32 as default, see #6985 (and this blog post with more context: https://tirania.org/blog/archive/2018/Apr-11.html ). Unfortunately this breaks soft float support on ARM and we didn't even notice. As a workaround you can use MONO_ENV_OPTIONS='-O=-aot,-float32' for now.

Note to myself: passing --host=arm-linux-gnueabi to configure is not enough to get soft float. we try to be smart at runtime and detect if vfp is available (which it is on our dev boards). to force soft float use MONO_ARM_FORCE_SOFT_FLOAT=1 at runtime.

We can fix it, but I think it's easier to just force -O=-float32 on such targets.

solabc16 · 2019-01-31T19:40:46Z

Hello @lewurm, thanks for the above - including the background information, that's moved us moved.

This appears to have resolved the initial problem and we no longer receive the assertion when running either ikdasm or the application itself.

However, we now experience the SIGABRT below. This same application is running fine on ARMv7, AARCH64, x86 and x86_64 targets.

Are there any further optimisations we should look at disabling and/or any pointers for how to troubleshoot this further?

Hello @lewurm, following on from the above...

I started off with the somewhat coarse MONO_ENV_OPTIONS="--optimize=-all", which got the application running.

After a bit of trial and error, I managed to refine this to MONO_ENV_OPTIONS="--optimize=-float32,-inline".

So far testing has progressed well and we haven't run into any further issues. Is the use of inline optimisation expected to cause issues with ARMv5 machines? Let me know if you need any further details.

Best

James

lewurm · 2019-02-01T09:56:06Z

@solabc16 -inline should work, but it's likely that it exposes a bug somewhere else in the JIT. for the crash above could you install gdb on your machine. that will give you a better stack trace for the native side and post its output. (ideally use gist.github.com, in order to keep this issue readable 🙂 )

solabc16 · 2019-02-01T11:24:35Z

Ok @lewurm, thanks, I'll do some more work on this next week and get a better stack trace for this.

And yes... good point on gist!

Best

Hi, I'm also trying to build for armv5 but fail on runtime.

I'm building all jit libs on my x86 comp and the natives on the arm processor (with --disable-mcs-build). After it's all built I'm merging the two.

Tried building with
MONO_ENV_OPTIONS="--optimize=-float32,-inline" make
and
MONO_ENV_OPTIONS='-O=,-aot,-float32' make

but failed with both of them. any ideas?

https://gist.github.com/ricebus/3a78c6abd015d5991027ee1124dc3a3e

lewurm · 2019-06-18T07:16:26Z

@ricebus sorry I made I type in my comment above, it should be

MONO_ENV_OPTIONS='-O=-aot,-float32'

instead of

MONO_ENV_OPTIONS='-O=,-aot,-float32'

If everything fails, try MONO_ENV_OPTIONS='-O=-all'. Note that you must pass this environment on the target, where you actually run the mono runtime.

ricebus · 2019-06-18T14:44:51Z

Oh, I didn't get that. I thought it's a compile time flag.
Well, it runs now but I get different errors (I know that app works because an older build of Mono works)

https://gist.github.com/ricebus/67bd0477f8f95d25a5f654c20ebb52a8

lewurm · 2019-06-21T15:48:51Z

@ricebus this is a different problem, please open a separate issue for that

And same as above when running an app.

I've exported MONO_ENV_OPTIONS='-O=,-aot,-float32,-inline' and programs seem to work now, but libglib2.0-cil installation is still broken. Are there any plans to fix it in some official way?

- ref: mono/mono#12537

* Update mono - update mono to version 5.20 - update mono icon - add symlinks (fix #3755) - remove obsolete patch * add workaround for mono bug with armv5 - ref: mono/mono#12537

erikmollink · 2020-06-04T22:27:16Z

In the workaround the SYNOPKG_DSM_ARCH 88f6282 should also be included as this model throws the same error.

Stanzilla · 2020-11-16T14:06:44Z

Yup, 88f6282 is needed as well.

mreid-tt · 2023-07-09T10:52:57Z

Was wondering if there were any updates on this issue. We recently had a user on a 88f6281 arch experience crashes on the initial install. In both cases the script was running the cert-sync function. I don't believe that the cert-sync is able to use the environment variables proposed above to workaround the issue. Below are the logs with two different builds. For mono version (5.20.1.34):
