Attempting to set some bits in the Unicorn EFLAGS doesn't work.
 2015-11-10 10:36:01 +08:00
farmdve 726f45b33d Attempting to set some bits in the Unicorn EFLAGS doesn't work. 
When attempting to set all flags except trap flag, the EFLAGS value
should be 0x00244ED7, I've tested this on Windows and here
https://ideone.com/WQAvk1 which is presumably Linux.

Unicorn however has the value 0x00000ED7, bits 11-21 are not set. Bit 21
is the ID bit indicating whether or not CPUID is available.

X86 zero-byte opcode causes Unicorn to crash.

Nguyen Anh Quynh b3dfde8a17 Merge branch 'master' of https://github.com/unicorn-engine/unicorn 2015-11-05 20:41:51 +08:00
farmdve 7f3c567ae5 X86 zero-byte opcode causes Unicorn to crash. 
The opcode 0x00 translates as `add byte ptr ds:[eax],al`, which leads to
a segfault in Unicorn.

Using a debugger, I believe the crash is located in
`qemu/translate-all.c` in function `page_flush_tb_1`, more specifically
this code `pd[i].first_tb = NULL;`
