- Subject: [patch, fortran, committed] Fix display of BLOCK variables in Fortran dumps
Hello world,
I committed the attached patch as obvious (revision 173223) after
regression-testing. No test case because we can't do that for the
Fortran dumps (yet).
With this patch, variables inside a BLOCK construct are displayed with
their attributes, for example
program main
block
real, dimension(2) :: x
end block
end program main
is now displayed as
Namespace: A-H: (REAL 4) I-N: (INTEGER 4) O-Z: (REAL 4)
procedure name = main
symtree: 'main' || symbol: 'main'
type spec : (UNKNOWN 0)
attributes: (PROGRAM PUBLIC SUBROUTINE)
code:
BLOCK
symtree: 'block@1' || symbol: 'block@1'
type spec : (UNKNOWN 0)
attributes: (LABEL )
symtree: 'x' || symbol: 'x'
type spec : (REAL 4)
attributes: (VARIABLE DIMENSION)
Array spec:(1 [0] AS_EXPLICIT 1 2 )
END BLOCK
instead as being displayed as being 'from block@1'.

* dump-prase-tree.c (show_code_node): Set the current
namespace to the BLOCK before displaying it; restore
afterwards.
