Bug in Intel LLVM fortran compiler?

[Rubo]

Compiling a regular modern Fortran code I got this error. I am wondering if I hit a bug in the compiler: 

LLVM ERROR: Cannot select: 0x8aed4b0: i32 = zero_extend 0x88482e0, /programming/SIMPLE/src/utils/simple_linalg.f90:838:41

there is not enough information here for us to comment or help.

First, what version of IFX? 

What OS?

What application, compiler options, etc.

Ideally we could use a .zip or .tgz of the application or a pointer to it's github location.

[Rubo]

IFX version ifx (IFX) 2024.0.2 20231213

Linux OEL8 Red Hat Enterprise Linux release 8.9 (Ootpa)

Application: https://github.com/hael/SIMPLE

Compilation script: https://github.com/hael/SIMPLE/compile_intel.sh

Thanks!!!

I cannot get far enough into the build to see what you are seeing.  Is there a branch you are using?

I also changed the CXX compiler to 'icpx' instead of icx-cc

First I hit 

[  4%] Building Fortran object lib/CMakeFiles/SIMPLE3.0.0.dir/utils/simple_rnd.f90.o

which looks like it could be a bug reported already.  

So I replaced 'long' with '

selected_int_kind(9)'

which you had as it's kind in defs.  that got me past simple_rnd.f90.  Then I hit a slew of errors

[Rubo]

I am using the master branch. This is really interesting,, which is the version of IFX that you are using?

[Rubo]

Ron, I was able to reproduce your error with IFX versions 2023.1.0 and 2023.2.0.

Using IFX 2024.1.0 I got the errors reported initially in my post.
