Severity: normal
Tags: patch
Please enable PRIF support in flang-22+ for coarrays.
Flang since 22+ has experimental support for co-arrays:
```
alastair@sid:~/deb-packages/llvm$ cat hello.f90
program main
implicit none
write (*,*) "Hello from image", this_image(), "of", num_images()
end program main
$ flang-22 -o hello hello.f90 -fcoarray -lcaffeine-smp -lgasnet-smp-seq
-L/usr/lib/aarch64-linux-gnu/fortran/flang/ -lassert
warning: Support for multi image Fortran features is still experimental and in
development.
$ alastair@sid:~/deb-packages/llvm$ gasnetrun_smp -n 2 ./hello
Hello from image 1 of 2
Hello from image 2 of 2
```
currently static libraries, so multiple needed for linking.
Try building caffeine with shared libs.
llvm-22, patch debian/rules:
```
ifneq (,$(filter $(DEB_HOST_ARCH), $(FLANG_ARCHS)))
PROJECTS += ;flang
RUNTIMES += ;flang-rt
+ STAGE_ALL_CMAKE_EXTRA += -DFLANG_ENABLE_PRIF=ON
endif
```
(I am the maintainer of fortran-caffeine and gasnet, the libraries that supply
PRIF for flang.
coarray support is under active development)
Thanks
Alastair
