2013-10-10tcg: Add qemu_ld_st_i32/64Richard Henderson1-0/+2

GUEST_BASE support is now supported by all TCG backends, and is now mandatory. Drop the now-pointless TCG_TARGET_HAS_GUEST_BASE define (set by every backend) and the error if it is unset.

2012-09-15Remove unused CONFIG_TCG_PASS_AREG0 and dead codeBlue Swirl1-1/+0
Now that CONFIG_TCG_PASS_AREG0 is enabled for all targets, remove dead code and support for !CONFIG_TCG_PASS_AREG0 case. Remove dyngen-exec.h and all references to it. Although included by hw/spapr_hcall.c, it does not seem to use it. Remove unused HELPER_CFLAGS. Signed-off-by: Blue Swirl <blauwirbel@gmail.com> Reviewed-by: Richard Henderson <rth@twiddle.net>
2012-03-03w64: Change data type of parameters for flush_icache_rangeStefan Weil1-1/+2
The TCG targets i386 and tci needed a change of the function prototype for w64. This change is currently not needed for the other TCG targets, but it can be applied to avoid code differences.

2011-10-01tcg: Don't declare TCG_TARGET_REG_BITS in tcg-target.hStefan Weil1-6/+0
It is now declared for all tcg targets in tcg.h, so the tcg target specific declarations are redundant. Signed-off-by: Stefan Weil <weil@mail.berlios.de> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
2011-08-21tcg: Always define all of the TCGOpcode enum members.Richard Henderson1-33/+35
By always defining these symbols, we can eliminate a lot of ifdefs. To allow this to be checked reliably, the semantics of the TCG_TARGET_HAS_* macros must be changed from def/undef to true/false. This allows even more ifdefs to be removed, converting them into C if statements. Signed-off-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>

2010-06-16tcg: Optionally sign-extend 32-bit arguments for 64-bit hosts.Richard Henderson1-0/+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.

2009-12-05S/390 fake TCG implementationAlexander Graf1-0/+69
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.
