[PATCH v2 00/74] semihosting cleanup |
Date: |
Tue, 3 May 2022 12:47:29 -0700 |
Changes for v2:
* Drop m68k and nios2 patches to move semihosting exception to helper.
* Merge semihosting console into GuestFD.
* Split syscalls into new files.
Having them in guestfd.[ch] seemed wrong.
* Standardize on GDB remote-protocol errno. Having done this, I'm
not sure it's the best idea -- mips and xtensa semihosting have a
larger set of errno values than GDB. Better, perhaps, to standardize
on host errno and then convert GDB errno back to host on the way
out of gdbstub.c:handle_file_io.
* Convert mips and xtensa to semihosting/syscalls.h
* Implement rx semihosting, with tests.
Still on the to-do list:
* Non-Coldfire m68k semihosting. The libgloss spec says that "bkpt"
may be used when "halt" is not available in the ISA. Add m68k
semihosting tests -- we already have a cross toolchain in docker,
so this should be easy.
* Support dynamic endianness in arm-compat-semi.c; add tests for
aarch64 big-endian system mode.
* Split this patch set. :-)
