@Patryk27 @benshi001 @kazutakahirata

Oops, as you noticed I did not recompile after adding the avr64* models.

Sorry for that, changes are almost never trivial....
Hope all is ok now, my local compile did compile my files, but ended with:

cc1plus: fatal error: /home/tom/src/rust/llvm-project/llvm/lib/DebugInfo/LogicalView/Core/LVSourceLanguage.cpp: No such file or
directory
compilation terminated.

Hmm. I just tried your patch, but I didn't seem the same error.

kazutakahirata

LGTM. Thank you for updating the patch!

tomtor · 2025-06-14T17:06:10Z

LGTM. Thank you for updating the patch!

Thanks! I am now rebuilding after:

cmake -S llvm -B build -G Ninja

tomtor · 2025-06-14T21:59:53Z

My local tree build OK...

kazutakahirata · 2025-06-15T00:12:50Z

@tomtor https://github.com/llvm/llvm-project/actions/runs/15653757180/job/44101995731?pr=144229

is showing:

/home/gha/actions-runner/_work/llvm-project/llvm-project/clang/test/Misc/target-invalid-cpu-note/avr.c:314:16: error: CHECK-SAME: expected string not found in input
// CHECK-SAME: {{^}}, atmega808
               ^

I also see the same thing with check-clang. Is this related to your PR?

tomtor · 2025-06-15T07:17:08Z

@kazutakahirata Thanks again!

I noticed the failling check but could not find the cause in the enormous log file. Wondered if it could be caused by a timeout on the build, but it was this failing check.

Added new test patterns for the new MCUs.

Did not manage to run these tests locally yet, but will figure that out.

tomtor · 2025-06-15T07:59:24Z

In the CI check I find one FAIL:

2025-06-15T07:21:48.1250696Z FAIL: Flang :: Semantics/modfile76.F90 (3383 of 3529)
2025-06-15T07:21:48.1251772Z ******************** TEST 'Flang :: Semantics/modfile76.F90' FAILED ********************

but this is unrelated? (Flang, fortran)

benshi001 · 2025-06-15T09:18:28Z

This flang failure did not relate to your AVR patch, just omit it.

For future reference, the avr16/avr32 devices do have SPM and SPMX features, but the current xmega3 definition has not.

Xmega3 is also used for modern attiny series which do not have SPM(X), so that is correct.

The avr64 devices use xmega2 which has SPM(X) defined, so that is also ok.

I prefer to leave the avr16/avr32 devices unchanged (using xmega3 to be in sync with gcc definitions), because the SPM instructions write flash and users can use asm if they want that feature. In addition LLVM will never generate these?

For me this PR is complete now. @benshi001 add this comment to the commit message?

kazutakahirata · 2025-06-15T17:40:31Z

@tomtor @benshi001 I just tried your latest revision on the top of tree, and both check-llvm and check-clang passed.

It is OK to keep in sync with gcc, thanks. llvm-avr never generate unsupported features for devices.
