2012-06-28x86: avoid AREG0 for exceptionsBlue Swirl
Add an explicit CPUX86State parameter instead of relying on AREG0. Merge raise_exception_env() to raise_exception(), likewise with raise_exception_err_env() and raise_exception_err().

2012-01-11target-i386: fix SSE rounding and flush to zeroAurelien Jarno
SSE rounding and flush to zero control has never been implemented. However given that softfloat-native was using a single state for FPU and SSE and given that glibc is setting both FPU and SSE state in fesetround(), this was working correctly up to the switch to softfloat. Fix that by adding an update_sse_status() function similar to update_fpu_status(), and callin git on write to mxcsr. Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
2011-10-24i386: wire up MSR_IA32_MISC_ENABLEAvi Kivity

2011-07-30exec.h cleanupBlue Swirl
Move softmmu_exec.h include directives from target-*/exec.h to target-*/op_helper.c. Move also various other stuff only used in op_helper.c there. Define global env in dyngen-exec.h. For i386, move wrappers for segment and FPU helpers from user-exec.c to op_helper.c. Implement raise_exception_err_env() to handle dynamic CPUState. Move the function declarations to cpu.h since they can be used outside of op_helper.c context. LM32, s390x, UniCore32: remove unused cpu_halted(), regs_to_env() and env_to_regs(). ARM: make raise_exception() static. Convert #include "exec.h" to #include "cpu.h" #include "dyngen-exec.h" and remove now unused target-*/exec.h. Signed-off-by: Blue Swirl <blauwirbel@gmail.com>

2011-06-26x86: use caller supplied CPUState for interrupt related stuffBlue Swirl
Several x86 specific functions are called from cpu-exec.c with the assumption that global env register is valid. This will be changed later, so make the functions use caller supplied CPUState parameter. It would be cleaner to move the functions to helper.c, but there are quite a lot of dependencies between do_interrupt() and other functions. Add helpers for svm_check_intercept() and cpu_cc_compute_all() instead of calling the helper (which uses global env, AREG0) directly. Signed-off-by: Blue Swirl <blauwirbel@gmail.com>

With softfloat it's not possible to play with the overflow of an unsigned value to get the 0 case partially correct. Use a special case for that. Using a division to generate an infinity is the easiest way that works for both softfloat and softfloat-native.

2010-02-28target-i386: fix crash on x86 32bit linux host with hw breakpoint exceptionsJason Wessel
If you make use of hw breakpoints on a 32bit x86 linux host, qemu will segmentation fault when processing the exception. The problem is that the value of env is stored in $ebp in the op_helper raise_exception() function, and it can have the wrong value when calling it from non generated code. It is possible to work around the problem by restoring the value of env before calling raise_exception() using a new helper function that takes (CPUState *) as one of the arguments.

lzcnt is a AMD Phenom/Barcelona added instruction returning the number of leading zero bits in a word. As this is similar to the "bsr" instruction, reuse the existing code. There need to be some more changes, though, as lzcnt always returns a valid value (in opposite to bsr, which has a special case when the operand is 0). lzcnt is guarded by the ABM CPUID bit (Fn8000_0001:ECX_5).
