This patch allows the gdb DWARF reader to handle variables located in Fortran common blocks. This fixes 20 unexpected failures in the gdb.fortran testsuite with host, target and build triplet x86_64-apple-darwin13.4.0 with gfortran 4.9.2.
Re-posted as requested with patch file attached. Revised from original post to prevent double relocation.
2015-04-12 George Helffrich <ghfbsd@gmail.com>
* dwarf2read.c (read_common_block): Relocate symbols in Fortran common
blocks properly, and avoid double relocation.
(read_new_symbol_full): Don't discard zero-offset symbols in Fortran
common blocks.
(_initialize_dwarf2_read): Add debug diagnostic print for common
symbols.
* psymtab.c (print_partial_symbols): Recognize and print
COMMON_BLOCK_DOMAIN.
* symmisc.c (print_symbol): Recognize and dump LOC_COMMON_BLOCK.

Hi George, Luis,
I manually patched last week and got 16 fails in the common block testcase.
Just adding a base-address to the variables lead to failing tests.
From what I have seen, all the child's of the common block have their
own fix (DW_OP_addr) location.
At least in my environment when I check the DWARF of the compiled testcase.
Here an excerpt of my DWARF
<2><4a>: Abbrev Number: 3 (DW_TAG_common_block)
<4b> DW_AT_name : (indirect string, offset: 0x0): fo_o
<4f> DW_AT_decl_file : 1
<50> DW_AT_decl_line : 31
<51> DW_AT_linkage_name: (indirect string, offset: 0x5): fo_o_
<55> DW_AT_location : 9 byte block: 3 60 10 60 0 0 0 0 0
(DW_OP_addr: 601060)
<5f> DW_AT_sibling : <0xa1>
<3><63>: Abbrev Number: 4 (DW_TAG_variable)
<64> DW_AT_name : ix
<67> DW_AT_decl_file : 1
<68> DW_AT_decl_line : 23
<69> DW_AT_type : <0x116>
<6d> DW_AT_external : 1
<6d> DW_AT_location : 9 byte block: 3 60 10 60 0 0 0 0 0
(DW_OP_addr: 601060)
<3><77>: Abbrev Number: 4 (DW_TAG_variable)
<78> DW_AT_name : iy2
<7c> DW_AT_decl_file : 1
<7d> DW_AT_decl_line : 24
<7e> DW_AT_type : <0x11d>
<82> DW_AT_external : 1
<82> DW_AT_location : 9 byte block: 3 64 10 60 0 0 0 0 0
(DW_OP_addr: 601064)
May George can sent the important part of the DWARF
