插桩之路——为QEMU TCG添加helper以target/i386/translate.c中的gen_helper_syscall为例讲解了添加helper函数的步骤和方法;然后是TCG的定义机制,即gen_helper_xxx和helper_xxx函数的定义机制。 QEMU: Call a Custom Function from TCG以target/arm/translate.c中的gen_helper_exception为例讲解了helper函数的调用模式,...
Add an instructions bool parameter to get_ticks() to correctly return icount_get_raw() when icount_enabled() == 1 and instruction count is queried. This will modify the existing behavior which was returning an instructions count close to the number of cycles (CPI ~= 1). Signed-off-by:...

the instruction is defined to be implemented as a simple negation followed by a multiply-add — in this case if the negated input was a NaN it will emerge from the other side with its sign bit flipped. But some CPU architectures, like PPC, specify that the whole instruction including nega...
