This is the fortran part of the patch, including tests, which are essentially unchanged from Siddhesh's original 2012 submission: https://sourceware.org/ml/gdb-patches/2012-08/msg00562.html There is, however, one large departure. In the above thread, Jan pointed out problems with GCC debuginfo for -m32 builds (filed usptream as gcc/54934). After investigating the issue, I am dropping the hand-tweaked assembler source file to workaround this case. While I would normally do something to accommodate this, in this case, given the ubiquity of 64-bit systems today (where the tests pass) and the apparent lack of urgency on the compiler side (by users), I don't think the additional complexity and maintenance costs are worth it. It will be very routinely tested on 64-bit systems. [For example, at Red Hat, we always test -m64 and -m32 configurations for all GDB releases.] gdb/ChangeLog: From Siddhesh Poyarekar: * f-lang.h (f77_get_upperbound): Return LONGEST. (f77_get_lowerbound): Likewise. * f-typeprint.c (f_type_print_varspec_suffix): Expand UPPER_BOUND and LOWER_BOUND to LONGEST. Use plongest to format print them. (f_type_print_base): Expand UPPER_BOUND to LONGEST. Use plongest to format print it. * f-valprint.c (f77_get_lowerbound): Return LONGEST. (f77_get_upperbound): Likewise. (f77_get_dynamic_length_of_aggregate): Expand UPPER_BOUND, LOWER_BOUND to LONGEST. (f77_create_arrayprint_offset_tbl): Likewise. gdb/testsuite/ChangeLog: * gdb.fortran/array-bounds.exp: New file. * gdb.fortran/array-bounds.f90: New file.
