[PATCH v2 00/11] single-binary: compile once semihosting

Posted by Pierrick Bouvier 2 months, 2 weeks ago

This series compiles once semihosting files in system mode.
The most complicated file was semihosting/arm-compat-semi.c, which was carefully
cleaned in easy to understand steps.

v2
--

- use vaddr for syscalls.c/.h
- static qualifier for console_{in,out}_gf
- use vaddr for arm-compat-semi.c
- semihosting/arm-compat-semi: fix cast for common_semi_set_ret

Pierrick Bouvier (11):
  semihosting/syscalls: compile once in system and per target for user
    mode
  semihosting/syscall: replace uint64_t with vaddr where appropriate
  semihosting/guestfd: compile once for system/user
  semihosting/arm-compat-semi: remove common_semi_sys_exit_extended
  target/{arm,riscv}/common-semi-target: eradicate target_ulong
  include/semihosting/common-semi: extract common_semi API
  semihosting/arm-compat-semi: eradicate sizeof(target_ulong)
  semihosting/arm-compat-semi: replace target_ulong with uint64_t
  semihosting/arm-compat-semi: replace target_long with int64_t
  semihosting/arm-compat-semi: remove dependency on cpu.h
  semihosting/arm-compat-semi: compile once in system and per target for
    user mode
