CHARACTER(3) foo = 'abc'



  DW_AT_name = "character(3)"
  DW_AT_byte_size = 3

It is understood that LLVM will add a superfluous DW_AT_encoding attribute as well. This has not been a real issue when testing existing debuggers with our Fortran compilers. It is generally expected that debuggers will ignore attributes that they don't understand in context. This patch enables the display of CHARACTER type variables under gdb when using flang, for example.

(gdb) p foo
$1 = 'abc'
