A recent patch to descriptor.cpp added some code whose style isn't conforming with the rest of the file (or the runtime). We always use braces around initializations and nested statements, and don't indent "case" lines any more than their "switch". Further, it dumps a rank 0 descriptor as just "scalar", which is fine as an interpretation of the rank but should not entirely replace the rank in the dump output.

There was a problem hiding this comment.
Thanks Peter for letting me know about flang-rt specific style requirements.

Peter, will you mind if I take these changes for a reapply of the original patch? |

…extension. (#170389) This is a reapply the original patch (#169137) with the flang-rt unit test changes limiting it to linux platform only. Additionally accommodated style changes from Peter Klausler (#170227) show_descriptor intrinsic prints details of a descriptor (extended Fortran pointer). It accepts a descriptor for any type and rank, including scalars. Requires use of flang_debug module. Example: ``` program test use flang_debug implicit none integer :: a(4) = (/ 1,3,5,7 /) call show_descriptor(a(1:3)) end program test ``` and its output: ``` Descriptor @ 0x7ffe01ec6a98: base_addr 0x563b7035103c elem_len 4 version 20240719 rank 1 type 9 "INTEGER(kind=4)" attribute 0 extra 0 addendum 0 alloc_idx 0 ```
