Pierrick Bouvier	d8028d4ede	semihosting/guestfd: compile once for system/user We move relevant code to semihosting/arm-compat-semi.c, and add functions to query CONFIG_ARM_COMPATIBLE_SEMIHOSTING at runtime.

Philippe Mathieu-Daudé	83fb360d6a	semihosting/guestfd: Remove unused 'semihosting/uaccess.h' header Nothing in guestfd.c requires "semihosting/uaccess.h" nor "qemu.h".

Philippe Mathieu-Daudé	f14eced5ac	semihosting: Rename softmmu_FOO_user() -> uaccess_FOO_user() Add a check in 'softmmu-uaccess.h' that the header is only include in system emulation, and rename it as 'uaccess.h'. Rename the API methods: - softmmu_[un]lock_user() -> uaccess_[un]lock_user() - softmmu_strlen_user() -> uaccess_strlen_user(). Update a pair of comments.

Alex Bennée	c566080cd3	gdbstub: move syscall handling to new file Our GDB syscall support is the last chunk of code that needs target specific support so move it to a new file. We take the opportunity to move the syscall state into its own singleton instance and add in a few helpers for the main gdbstub to interact with the module. I also moved the gdb_exit() declaration into syscalls.h as it feels pretty related and most of the callers of it treat it as such.

Richard Henderson	e4a4aaa51b	semihosting: Create qemu_semihosting_guestfd_init For arm-compat, initialize console_{in,out}_gf; otherwise, initialize stdio file descriptors. This will go some way to cleaning up arm-compat, and will allow other semihosting to use normal stdio.

Richard Henderson	5eadbbfca6	semihosting: Split out semihost_sys_close Split out the non-ARM specific portions of SYS_CLOSE to a reusable function. This handles all GuestFD. Note that gdb_do_syscall %x reads target_ulong, not int. Reviewed-by: Luc Michel <lmichel@kalray.eu> Signed-off-by: Richard Henderson <richard.henderson@linaro.org>	4 years ago
Richard Henderson	5b3f39cb04	semihosting: Split out semihost_sys_open Split out the non-ARM specific portions of SYS_OPEN to a reusable function. This handles gdb and host file i/o. Add helpers to validate the length of the filename string. Prepare for usage by other semihosting by allowing the filename length parameter to be 0, and calling strlen.

Richard Henderson	1c6ff7205b	semihosting: Split out guestfd.c In arm-compat-semi.c, we have more advanced treatment of guest file descriptors than we do in other implementations. Split out GuestFD and related functions to a new file so that they can be shared.
