Subject: [PATCH 3/3] gdbsupport: move fileio_errno_to_host to fileio.{h.cc} and rename
Date: Fri, 26 Aug 2022 15:54:59 -0400 [thread overview]
Message-ID: <20220826195459.2540898-3-simon.marchi@efficios.com> (raw)
In-Reply-To: <20220826195459.2540898-1-simon.marchi@efficios.com>
We have a downstream change in ROCm-GDB to move fileio_errno_to_host to
gdbsupport/fileio.{h,cc}, so we can use it outside of gdb_bfd.c. Even
though there is nothing upstream that would need this, I think it's a
change that makes sense, that fileio_errno_to_host belongs there,
alongside host_to_fileio_error.
Rename it fileio_error_to_host, for symmetry with host_to_fileio_error.
