Hi Joel,
I tested the GDB 7.7 branch using GCC 4.9 to build it, and found some
errors.
In file included from ../../gdb/defs.h:104:0,
from ../../gdb/cli/cli-dump.c:22:
../../gdb/cli/cli-dump.c: In function 'dump_bfd_file':
../bfd/bfd.h:302:108: error: right-hand operand of comma expression has no effect [-Werror=unused-value]
#define bfd_set_section_vma(bfd, ptr, val) (((ptr)->vma = (ptr)->lma = (val)), ((ptr)->user_set_vma = TRUE), TRUE)
^
../../gdb/cli/cli-dump.c:197:3: note: in expansion of macro 'bfd_set_section_vma'
bfd_set_section_vma (obfd, osection, vaddr);
^
../bfd/bfd.h:303:83: error: right-hand operand of comma expression has no effect [-Werror=unused-value]
#define bfd_set_section_alignment(bfd, ptr, val) (((ptr)->alignment_power = (val)),TRUE)
^
../../gdb/cli/cli-dump.c:198:3: note: in expansion of macro 'bfd_set_section_alignment'
bfd_set_section_alignment (obfd, osection, 0);
They have been fixed by the following commit:
commit 27b829ee701e29804216b3803fbaeb629be27491
Author: Nick Clifton <nickc@redhat.com>
Date: Wed Jan 29 13:46:39 2014 +0000
So I am proposing that we backport this commit to the 7.7 branch. I can
do that if it is OK.
WDYT? Thanks,
