Sergio Durigan Junior bc3b087de2 Extend "set cwd" to work on gdbserver ... This is the "natural" extension necessary for the "set cwd" command (and the whole "set the inferior's cwd" logic) to work on gdbserver. The idea here is to have a new remote packet, QSetWorkingDir (name adopted from LLDB's extension to the RSP, as can be seen at <https://raw.githubusercontent.com/llvm-mirror/lldb/master/docs/lldb-gdb-remote.txt>), which sends an hex-encoded string representing the working directory that the remote inferior will use. There is a slight difference from the packet proposed by LLDB: GDB's version will accept empty arguments, meaning that the user wants to clear the previously set working directory for the inferior (i.e., "set cwd" without arguments on GDB). For UNIX-like targets this feature is already implemented on nat/fork-inferior.c, and all gdbserver has to do is to basically implement "set_inferior_cwd" and call it whenever such packet arrives. For other targets, like Windows, it is possible to use the existing "get_inferior_cwd" function and do the necessary steps to make sure that the inferior will use the specified working directory. Aside from that, the patch consists basically of updates to the testcase (making it available on remote targets) and the documentation. No regressions found. gdb/ChangeLog: 2017-10-04 Sergio Durigan Junior <sergiodj@redhat.com> * NEWS (Changes since GDB 8.0): Add entry about new 'set-cwd-on-gdbserver' feature.
