Please use optimization and debug args instead of buildtype. -g3
is already in debug args. Other options are for optimization.

This line is overcomplicated. Please imbricated for loops instead. Not sure why you iterate through a one-item list.
The MIL thing is a bit problematic as it is unique to this compiler and thus makes it a notable maintenance burden (as we don't have access to said compiler at all). All other compilers that I know of do this by outputting plain .o files with extra data in them (this is how link-time optimization works in e.g. Clang et al). Is there any data on how effective it is compared to plain unity builds? That is, if people could get the same performance using builtin unity support rather than this very toolchain specific thingy, would we need to support MIL at all? |
Unfortunately, I do not have any performance data. At first I didn't want to implement the MIL linking for the very reason you mention, but I was unable to make unity build work for the project I was converting to Meson due to some conditional compilation pattern used in almost all files, which pull in a specified part generated headers. With MIL linking, this is not a problem, files are compiled in an identical manner until this MIL intermediate language part. Not sure how to approach the fact that the compiler is not available for use, the best that I could think of was writing a dummy CLI emulation of the compiler, so some tests could run at the very least. |
Thanks for the TASKING Compiler support PR, I successfully used it with TASKING v6.3r1 to build firmware for Infineon TriCore TC375. The output hex file was flashed and it runs successfully on target. |
Hi, Is it possible to share sample files or configurations required to set up a build directory for Tasking Tricore please? Thank you. The cross_build.txt file I am using is attached. I ran command : meson setup --cross-file cross_build.ini builddir But I am getting errors :
One other question, I don't understand why I am getting :
Is there something I missed in my configurations ? I am not expecting my Visual Studio installation to be used in this build. Thank you. |
This should work, however, I did not implement support for C++. Not sure why it wants VS, for good measure I would pass in --wipe when configuring.

Will not show if you have gcc installed. The section of meson code responsible for this is in Interpreter.py :
It is possible to follow the instructions to install MinGW here : This will allow the shutil.which('gcc') to be True, and the function will return with 'False'. However, this does not solve the original problem of the generation crash. I am still looking into this. |
Hi, Update : I am now able to generate my build folder. An additional modification is needed in my cross_build.txt file. The
entry needs to be specified as :
I will proceed with compilation and porting and will report any other findings here as well. Here is the stdout :
I have also attached the build setup log (meson-log.txt file for reference. Cross_build file : Command ran :
I notice in the meson-log.txt file that the archiver is used instead of the linker when detecting linker :

Sorry it's taken me so long to look at this. In general this all looks good. There's some thigns I think we can clean up here, but otherwise this looks fine from a code point of view.

You'll hit that exception when you don't have a C compiler, but no other cases it looks like. Can we handle that without a try/except

This looks like the same case, where the missing c
compiler is the issue.

The problem is that the target might not contain the built-in option, so it end ups throwing a KeyError. I've added a check if the target even contains it. Do you know any better solution? I've tried modifying the get_option call to fall back to the base_option var in the compilers.py file, but that had some CI failures.
But yes, the C compiler not being present is another problem, I've added a check for it.

Oh, main has the same CI failures, maybe the base_option fallback was not the culprit then.

Do you actually want to fall through here and end up with the system linker, link.exe
or ar
?
That looks like a Meson bug, we have the same message for both the archiver and dynamic linker... I'll send a patch for that. edit: #12784 |

We try really hard to avoid adding new options without a good reason (because otherwise you have 1000+ options in the blink of an eye). Since this is "sort of" a link time optimization, would it be possible to make the code use the |

I think that makes sense, I'll try to do that. Do you thing that 'b_lto' fits for the static library part of the MIL linking? What I mean is that right now, tasking_mil_link is possible to set for static libraries. This has the effect of LTO inside the library, but not with other code parts. However, it is possible to create MIL libraries, which behave as static libs, but still benefit from LTO at the actual link stage. Maybe a combination of prelink kward and b_lto could be used? |
I've just learned this, but there is a free, non-commercial version of the compiler bundled inside the Aurix Development Studio by Infineon. The compiler cannot be used outside the IDE though, a Meson build would have to be setup inside Eclipse. I am open to create a debug project, so you can try around with the compiler if any issues arise. |

What happens if you use both at the same time? Based on this description "LTO inside a static lib" is pretty much the same as prelinking whereas "LTO over mutliple libraries" is what Meson calls regular LTO. So hooking it up to those would make logical sense. |
There should be three possible results:
I think prelink should take priorioty, someone might set LTO for the whole project, but prelinking can only be set per target. Based on that: What do you think? |
