* tcg: Optionally sign-extend 32-bit arguments for 64-bit hosts.Richard Henderson2010-06-161-0/+2
| | | | | | | | | | | | | | | | | | 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.

* tcg: Add TYPE parameter to tcg_out_mov.Richard Henderson2010-06-091-1/+1
| | | | | | | | | | | | | | Mirror tcg_out_movi in having a TYPE parameter. This allows x86_64 to perform the move at the proper width, which may elide a REX prefix. Introduce a TCG_TYPE_REG enumerator to represent the "native width" of the host register, and to distinguish the usage from "pointer data" as represented by the existing TCG_TYPE_PTR. Update all targets to match. Signed-off-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>

* S/390 fake TCG implementationAlexander Graf2009-12-052-0/+174
Qemu won't let us run a KVM target without having host TCG support. Well, for now we don't have any so let's implement a fake target that only stubs out everything. I tried to keep the patch as close to Uli's source as possible, so whenever he feels like it he can easily diff his version against this one.
