Detailed Description

Semihosting call information structure.

This structure describes how a semi-hosting call is implemented. It contains debug information (e.g., the name of the call), a pointer to the implementation, and information needed to read its parameters from guest memory.

Member Data Documentation

◆ argc32

int ArmSemihosting::SemiCall::argc32

Number of aarch32 arguments to read from guest memory.

-1 if unimplemented.

Definition at line 305 of file semihosting.hh.

Referenced by ArmSemihosting::call32().

◆ argc64

int ArmSemihosting::SemiCall::argc64

Number of aarch32 arguments to read from guest memory.

-1 if unimplemented.

Definition at line 308 of file semihosting.hh.

Referenced by ArmSemihosting::call64().

◆ call

RetErrno(ArmSemihosting::* ArmSemihosting::SemiCall::call) (ThreadContext *tc, bool aarch64, std::vector< uint64_t > &argv)

Pointer to call implementation.

Parameters

tc	ThreadContext pointer for caller
aarch64	True if in aarc64 mode, false otherwise. argv Argument vector. argv[0] always corresponds to the pointer to the argument list. Remaining entries are read as consecutive words starting at the address pointed to by argv[0].

Returns: a (return value, errno) pair
