CC_AArch64_Custom_Block()

static bool CC_AArch64_Custom_Block ( unsigned &  ValNo, MVT &  ValVT, MVT &  LocVT, CCValAssign::LocInfo &  LocInfo, ISD::ArgFlagsTy &  ArgFlags, CCState &  State  )

static

Given an [N x Ty] block, it should be passed in a consecutive sequence of registers.

If no such sequence is available, mark the rest of the registers of that type as used and place the argument on the stack.

CC_AArch64_Custom_Stack_Block()

static bool CC_AArch64_Custom_Stack_Block ( unsigned &  ValNo, MVT &  ValVT, MVT &  LocVT, CCValAssign::LocInfo &  LocInfo, ISD::ArgFlagsTy &  ArgFlags, CCState &  State  )

static

The Darwin variadic PCS places anonymous arguments in 8-byte stack slots.

An [N x Ty] type must still be contiguous in memory though.
