2014-09-18target-i386: update fp status fixPavel Dovgalyuk1-8/+13
This patch introduces cpu_set_fpuc() function, which changes fpuc field of the CPU state and calls update_fp_status() function. These calls update status of softfloat library and prevent bugs caused by non-coherent rounding settings of the FPU and softfloat. v2 changes: * Added missed calls and intoduced setter function (as suggested by TeLeMan) Reviewed-by: TeLeMan <geleman@gmail.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com> Signed-off-by: Pavel Dovgalyuk <Pavel.Dovgaluk@ispras.ru>
2014-06-05softmmu: introduce cpu_ldst.hPaolo Bonzini1-4/+1
This will collect all load and store helpers soon. For now it is just a replacement for softmmu_exec.h, which this patch stops including directly, but we also include it where this will be necessary in order to simplify the next patch.

2014-05-28tcg: Invert the inclusion of helper.hRichard Henderson1-1/+1
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>

When we restore the mxcsr register with FXRSTOR, or set it with gdb, we need to update the various SSE status flags in CPUX86State Reported-by: Richard Purdie <richard.purdie@linuxfoundation.org> Reviewed-by: Paolo Bonzini <pbonzini@redhat.com> Signed-off-by: Richard Henderson <rth@twiddle.net>

2012-08-14x86: switch to AREG0 free modeBlue Swirl1-0/+4
Add an explicit CPUX86State parameter instead of relying on AREG0. Remove temporary wrappers and switch to AREG0 free mode. Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
2012-08-14x86: avoid AREG0 for FPU helpersBlue Swirl1-226/+207
Make FPU helpers take a parameter for CPUState instead of relying on global env. Introduce temporary wrappers for FPU load and store ops. Remove wrappers for non-AREG0 code. Don't call unconverted helpers directly. Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
