Richard Henderson	2bece2c883	tcg: Optionally sign-extend 32-bit arguments for 64-bit hosts. ... Some hosts (amd64, ia64) have an ABI that ignores the high bits of the 64-bit register when passing 32-bit arguments. Others require the value to be properly sign-extended for the type. I.e. "int32_t" must be sign-extended and "uint32_t" must be zero-extended to 64-bits. To effect this, extend the "sizemask" parameter to tcg_gen_callN to include the signedness of the type of each parameter. If the tcg target requires it, extend each 32-bit argument into a 64-bit temp and pass that to the function call. This ABI feature is required by sparc64, ppc64 and s390x.
