I am using a sample code from an old book but the code is written as inline assembly! I created a new console app project. added MASM dependancy and the file type is Microsoft Macro Assembler.
I keep getting this error whether it's targeted for 32 or 64!
=>MOVAPS XMM0, [esi] Exception thrown at 0x00D4101C in Project3.exe: 0xC0000005: Access violation reading location 0xFFFFFFFF Exception thrown at 0x00000000004F101C in Project3.exe: 0xC0000005: Access violation reading location 0xFFFFFFFFFFFFFFFF.
.model flat,c .const .data A dd 0.1,0.2,0.3,0.4 B dd 1,2,3,4 .code main PROC MOV esi, A MOV edi, B MOVAPS XMM0, [esi] MOVUPS XMM1, [edi] ADDPS XMM0, XMM1 MOVAPS XMM1, XMM0 MOVAPS[esi], XMM0 MOVUPS[edi], XMM1 main endp end
Any idea why it's not working? When I try to get the address of A and B instead of the address of the registers esi and edi, it works
so this works
MOVAPS XMM0, [A] MOVUPS XMM1, [B]
FYI The code works with the registers in inline assembly
