You'll need a GCC-specific enum (GCC_FP_INT_*, say) that GCC uses

This patch makes both TARGET_FUNCTION_ARG and
TARGET_FUNCTION_INCOMING_ARG take a function_arg_info.
They have to be done together since many targets use the

The current SIBCALL_REGS are x6, x7, and x28 to x31. These are all

I don't see any reason why we couldn't add t1, and a0 to a7 into this

This libgo patch by Cherry Zhang enables stricter GC checking in libgo.
With https://golang.org/cl/190599
(https://gcc.gnu.org/ml/gcc-patches/2019-08/msg01220.html), along with
what we do in greyobject, we ensure that we only mark allocated heap

When using the -msave-restore flag we end up with calls to
_riscv_save_0 and _riscv_restore_0. These functions adjust the stack
and save or restore the return address. Due to grouping multiple

save s0, s1, s2, and the return

Use function_arg_info for TARGET_CALLEE_COPIES.
The hook is passed the unpromoted type mode instead of the promoted mode.
The aarch64 definition is redundant, but worth keeping for emphasis.

For the SVE calling conventions, function_arg and function_arg_advance
need to know whether an argument is being passed by reference or not.
The simplest way of providing that information would have been to add a
new parameter, or convert the "named" parameter into a bitmask. But it
