2015-06-05target-s390x: implement TRANSLATE EXTENDED instructionAurelien Jarno
It is part of the basic zArchitecture instructions. Signed-off-by: Aurelien Jarno <aurelien@aurel32.net> Reviewed-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Alexander Graf <agraf@suse.de>
2015-06-05target-s390x: implement TRANSLATE AND TEST instructionAurelien Jarno
It is part of the basic zArchitecture instructions. Allow it to be call from EXECUTE. Reviewed-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net> Signed-off-by: Alexander Graf <agraf@suse.de>
2015-06-05target-s390x: implement LOAD FP INTEGER instructionsAurelien Jarno
This is needed to pass the gcc.c-torture/execute/ieee/20010114-2.c test in the gcc testsuite. Signed-off-by: Aurelien Jarno <aurelien@aurel32.net> Reviewed-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Alexander Graf <agraf@suse.de>

2015-06-05target-s390x: optimize (negative-) abs computationAurelien Jarno
Now that movcond exists, it's easy to write (negative-) absolute value using TCG code instead of an helper. Signed-off-by: Aurelien Jarno <aurelien@aurel32.net> Reviewed-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Alexander Graf <agraf@suse.de>

2014-05-28tcg: Invert the inclusion of helper.hRichard Henderson
Rather than include helper.h with N values of GEN_HELPER, include a secondary file that sets up the macros to include helper.h. This minimizes the files that must be rebuilt when changing the macros for file N. Reviewed-by: Alex Bennée <alex.bennee@linaro.org> Signed-off-by: Richard Henderson <rth@twiddle.net>

2013-01-05target-s390: Use noreturn for exception and load_pswRichard Henderson
Both always exit the cpu loop. Signed-off-by: Richard Henderson <rth@twiddle.net>

2013-01-05target-s390: Use TCG_CALL_NO_WG for integer helpersRichard Henderson
The division routines do not read or write tcg registers, but can raise fixed-point divide exceptions. Signed-off-by: Richard Henderson <rth@twiddle.net>
2013-01-05target-s390: Use TCG_CALL_NO_WG for floating-point helpersRichard Henderson
None of them read or write tcg registers, but most can raise fp exceptions. Signed-off-by: Richard Henderson <rth@twiddle.net>
2013-01-05target-s390: Use TCG_CALL_NO_WG for memory helpersRichard Henderson
Those that do not read or write tcg registers, but can raise exceptions via memory faults. Signed-off-by: Richard Henderson <rth@twiddle.net>
2013-01-05target-s390: Perform COMPARE AND SWAP inlineRichard Henderson
Still no proper solution for CONFIG_USER_ONLY, but the system version is significantly better. Signed-off-by: Richard Henderson <rth@twiddle.net>
