I want to get the data of the MPEG2ts data stream

checkasm : x86 : properly save rdx/edx in checked_call()
16 août 2015, par Henrik Gramnercheckasm : x86 : properly save rdx/edx in checked_call()
If the return value doesn’t fit in a single register rdx/edx can in some
cases be used in addition to rax/eax.Doesn’t affect any of the existing checkasm tests but might be useful later.
Also comment the relevant code a bit better.
