Hi,

I am getting a Compiler Aborting message when it is trying to compile a right shift of a uint64_t.

HWREG_BP(base + CAN_O_IF1DATB) = (uint32_t)(dataValue >> 32UL);

Compiler Message:

C:/ti/c2000/C2000Ware_0_04_00_06/libraries/soprano_60730_class_c/f2837xd/source/stl_can.c, line 417:
INTERNAL ERROR: no match for ASG

This may be a serious problem. Please contact customer support with a
description of this problem and a sample of the source files that caused this
INTERNAL ERROR message to appear.

Cannot continue compilation - ABORTING!

gmake: *** [stl_can.obj] Error 1
gmake: Target 'all' not remade because of errors.

**** Build Finished ****

Please preprocess the source file stl_can.c and submit that. Show all the build options exactly as the compiler sees them. What version of the compiler (not CCS) do you use?

Thanks and regards,

TI v15.12.1.LTS

-v28 -ml -mt --cla_support=cla1 --tmu_support=tmu0 --vcu_support=vcu2 --float_support=fpu32 -Ooff

--advice:performance=all -g --define=DEBUG --define=CPU1 --display_error_number --diag_warning=225 --diag_wrap=off --c_src_interlist

I am unable to generate a preprocessed file. It is unable to generate it because of errors.

... occurs after preprocessing is complete. So there is a file named stl_can.pp in that same directory. Please add the file extension .txt to it, and attach it to your next post.

Thanks and regards,

Here is the file. I was looking in the debug folder and couldn't find it earlier. Thanks!

stl_can.txt

Thank you for sending in a test case. I can reproduce the same error diagnostic. I filed CODEGEN-1732 in the SDOWP system to have this addressed. You are welcome to follow it with the SDOWP link below in my signature.

Thanks and regards,

The block of lines below my name is called the "signature". It contains a few links. The very last one is for SDOWP, where you can track your bug. If you are checking this soon, you should know it takes a few hours for things to propagate to the external view.

Thanks and regards,

This issue has already been fixed (as CODEGEN-1667). The fix is available in v.16.9.0.LTS and will be available shorty in 15.12.4.LTS (I'm working on releasing that version at present, it should be available within the next couple of weeks,)

Thanks,

Anna
