Keith Packard 3c37cfe0b1 semihosting: Change internal common-semi interfaces to use CPUState * ... This makes all of the internal interfaces architecture-independent and renames the internal functions to use the 'common_semi' prefix instead of 'arm' or 'arm_semi'. To do this, some new architecture-specific internal helper functions were created: static inline target_ulong common_semi_arg(CPUState *cs, int argno) Returns the argno'th semihosting argument, where argno can be either 0 or 1. static inline void common_semi_set_ret(CPUState *cs, target_ulong ret) Sets the semihosting return value. static inline bool common_semi_sys_exit_extended(CPUState *cs, int nr) This detects whether the specified semihosting call, which is either TARGET_SYS_EXIT or TARGET_SYS_EXIT_EXTENDED should be executed using the TARGET_SYS_EXIT_EXTENDED semantics. static inline target_ulong common_semi_rambase(CPUState *cs) Returns the base of RAM region used for heap and stack. This is used to construct plausible values for the SYS_HEAPINFO call. In addition, several existing functions have been changed to flag areas of code which are architecture specific: static target_ulong common_semi_flen_buf(CPUState *cs) Returns the current stack pointer minus 64, which is where a stat structure will be placed on the stack #define GET_ARG(n) This fetches arguments from the semihosting command's argument block. The address of this is available implicitly through the local 'args' variable. This is *mostly* architecture independent, but does depend on the current ABI's notion of the size of a 'long' parameter, which may need run-time checks (as it does on AARCH64) #define SET_ARG(n, val) This mirrors GET_ARG and stores data back into the argument block.
