Detailed Description
Information mainlined about RTL representation of incoming arguments.
Field Documentation
| rtx incoming_args::arg_offset_rtx |
This is the offset from the arg pointer to the place where the first
anonymous arg can be found, if there is one.
| CUMULATIVE_ARGS incoming_args::info |
Quantities of various kinds of registers
used for the current function's args.
| rtx incoming_args::internal_arg_pointer |
The arg pointer hard register, or the pseudo into which it was copied.
| int incoming_args::pops_args |
Number of bytes of args popped by function being compiled on its return.
Zero if no bytes are to be popped.
May affect compilation of return insn or of function epilogue.
| int incoming_args::pretend_args_size |
# bytes the prologue should push and pretend that the caller pushed them.
The prologue must do this, but only if parms can be passed in
registers.
| int incoming_args::size |
If function's args have a fixed size, this is that size, in bytes.
Otherwise, it is -1.
May affect compilation of return insn or of function epilogue.
