Andrei Vlad LUTAS	fad9c7e35c	BDDISASM v2.1.0 release - please consult the CHANGELOG for details about the modifications.	2 months ago
BITDEFENDER\vlutas	089e6d5e7e	Significant cleanup in disasmtool: the obsolete search functionality, and supplying registers for shemu from a file are no longer supported.	1 year ago
BITDEFENDER\vlutas	61382e95f0	Since all the shemu test file are synthetic and clean, I removed the password from the test archive.	1 year ago
Andrei Vlad LUTAS	f6050661d5	Multiple improvements in bdshemu ... Fixed an emulation bug for MOVZX and MOVSX instructions (https://github.com/bitdefender/bddisasm/issues/48) New shellcode flag - call tot Wow32 reserved. New shellcode flag - heaven's gate. New shellcode flag - stack-pivot. Moved bdshemu tests in a password protected zip file, so it doesn't trigger AV detections.	3 years ago
Andrei Vlad LUTAS	752bc626c4	Fixed RET with immediate - the immediate is not sign-extended. ... Fixed VEX decoding in 32 bit mode - vex.vvvv bit 3 is simply ignored. Fixed several FMA instructions decoding (L/W flag should be ignored). Print the 64 bit immediate value in disassembly, instead of the raw immediate (note that the operand always contains the sign-extended, full immediate). XBEGIN always uses 32/64 bit RIP size (0x66 does not affect its size). Decode WBINVD even if it's preceded by 0x66/0xF2 prefixes. Several mnemonic fixes (FXSAVE64, FXRSTOR64, PUSHA/PUSHAD...). Properly decode VPERMIL2* instructions. Fixed SSE register decoding when it is encoded in immediate. Decode SCATTER instructions even though they use the VSIB index as source. Some disp8 fixes (t1s -> t1s8/t1s16). SYSCALL/SYSRET are decoded and executed in 32 bit compat modem, even though SDM states they are invalid. RDPID uses 32/64 bit reg size, never 16. Various other minor tweaks & fixes. Re-generated the test files, and added some more, new tests.	4 years ago
