Hi,
When running test-case gdb.tui/tui-layout-asm.exp with target board
unix/-m32, we run into:
...
FAIL: gdb.tui/tui-layout-asm.exp: scroll to end of assembler (scroll failed)
...
Comparing screen dumps (edited a bit to fit column width) before:
...

and after:

13 | 0x80491b1 <__x86.get_pc_thunk.bp> mov (%esp),%ebp |
14 +--------------------------------------------------------------------+
...
it seems the mismatch comes from the extra indentation forced by the longer
<__x86.get_pc_thunk.bp> that was scrolled in.
Fix this by ignoring whitespace when comparing scrolled lines.
Tested on x86_64-linux, using -m64 and -m32.
Any comments?
Thanks,
- Tom
