Detailed Description

A complete layout blueprint for a forward call frame.

This structure is the primary output of prepare_forward_call_frame. It serves as a complete plan for the JIT engine, detailing every register and stack slot that needs to be populated before making the call instruction.

Member Data Documentation

arg_locations

infix_arg_location* infix_call_frame_layout::arg_locations

An array of location info for each argument.

is_variadic

bool infix_call_frame_layout::is_variadic

true if the function is variadic.

num_args

size_t infix_call_frame_layout::num_args

The total number of arguments.

num_gpr_args

uint8_t infix_call_frame_layout::num_gpr_args

The number of GPRs used for arguments.

num_stack_args

size_t infix_call_frame_layout::num_stack_args

The number of arguments passed on the stack.

num_xmm_args

uint8_t infix_call_frame_layout::num_xmm_args

The number of XMMs used for arguments.

return_value_in_memory

bool infix_call_frame_layout::return_value_in_memory

true if the return value uses a hidden pointer argument (struct return).

target_fn

void* infix_call_frame_layout::target_fn

The target function address.

total_stack_alloc

size_t infix_call_frame_layout::total_stack_alloc

Total bytes to allocate on the stack for arguments and ABI-required space.
