2012-03-24Add support for target helper functions which don't returnStefan Weil1-0/+7
Most functions which handle exceptions don't return. With a compiler attribute (added by QEMU_NORETURN), gcc can optimize the code. Signed-off-by: Stefan Weil <sw@weilnetz.de> Reviewed-by: Andreas Färber <afaerber@suse.de> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>

2010-06-16tcg: Optionally sign-extend 32-bit arguments for 64-bit hosts.Richard Henderson1-9/+29
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.

This change allows to define helpers returning pointers. This looks like a typo in original commit. Signed-off-by: igor.v.kovalenko@gmail.com Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
