In gdb/command/prompt.py:before_prompt_hook, the '\' in the new prompt
is replaced with '\\', shown as below,
> def before_prompt_hook(self, current):
> if self.value is not '':
> newprompt = gdb.prompt.substitute_prompt(self.value)
> return newprompt.replace('\\', '\\\\')
> else:
> return None
I don't see any explanations on this in comments nor email. As doc
said, "set extended-prompt \w" substitute the current working
directory, but it prints something different from what pwd or
os.getcwdu() prints on mingw32 host.
(gdb) python print os.getcwdu()^M
\\build2-lucid-cs\yqi\yqi\arm-none-eabi
(gdb) pwd^M
Working directory \\build2-lucid-cs\yqi\yqi\arm-none-eabi
(gdb) set extended-prompt \w
\\\\build2-lucid-cs\\yqi\\yqi\\arm-none-eabi
This makes me think whether the substitution in before_prompt_hook is
necessary or not. This patch is to remove this substitution.
Run gdb.python on x86_64-linux and arm-none-eabi on mingw32 host. No
regressions.
