            Bug ID: 30499
           Summary: reword "alignment ... is smaller than alignment ..."
                    warning
           Product: binutils
           Version: 2.41 (HEAD)
            Status: NEW
          Severity: normal
          Priority: P2
         Component: ld
          Assignee: unassigned at sourceware dot org
          Reporter: matz at suse dot de
  Target Milestone: ---

A customer of a customer of ours is requesting that the warning about
mismatching symbol alignments be reworded.  Given this:

% cat test1.s
  .type   com2_,@object
  .comm   com2_,8,64
  .quad   com2_
% cat test2.s
  .globl  com2_
  .data
  .align 32
  .type   com2_, @object
  .size   com2_, 8
com2_:
  .quad   2
% cat main.c
int main () {
        return 0;
}
% cc -c main.c test1.s test2.s
% cc main.o test1.o test2.o

The current warning is:
warning: alignment 32 of symbol `com2_' in test2.o is smaller than 64 in
test1.o

The proposal would be:
warning: alignment 32 of symbol `com2_' in test2.o changed to 64 to match
test1.o

I think the proposed warning is a little bit nicer as being explicit what the
resolution to the situation is.  I'm undecided if it's nicer enough to warrant
changing a translated warning, which is why I'm creating this PR, perhaps I
get opinions :-)
