Hi, Currently gdbstub is barely usable with i386-linux-user: GDB cannot even parse a shared library list, so no symbols are available. This boils down to unavailability of info proc, which is gated behind org.gnu.gdb.i386.linux. See amd64_linux_init_abi(); info proc is enabled by amd64_linux_init_abi_common() -> linux_init_abi().
This series adds orig_ax support to the emulator and gdbstub, and enables the existing test-proc-mappings.py on i386.
