When compiling the following instruction: movl 4(%ebp), 8(%eb开发者_开发百科p) I got: too many memory reference.
Every new generation of CPU introduces some sets of new instructions, i.e. MMX, 3DNOW, SSE and so on.
G开发者_StackOverflowoogle doesn\'t show the result, Anyone knows?The X means pair, and goes back to at least the 8080. It had 8-bit registers B,C,D,E,H,L (among others) which could also be used in p
I\'m generating some opcodes dynamically in a JIT compiler and I\'m looking for guidelines for opcode alignment.
This question already has answers here: What does the Visual Studio "Any CPU" target mean? (8 answers)
As it currently stands, this question is not a good fit for our Q&A format. We expect answers to be supported by facts, references,or expertise, but this question will likely solicit debate, a
I\'m doing some ASM code in a C code with the asm function. My env开发者_C百科ironment is DVL with gcc version 3.
I\'m in an interesting problem.I forgot I\'m using 64bit machine & OS and wrote a 32 bit assembly code. I don\'t know how to write 64 bit code.
What effect these tw开发者_开发百科o instructions cause in the assembly code generated by gcc for x86 machines:
The problem. Microsoft Visual C++ 2005 compiler, 32bit windows xp sp3, amd 64 x2 cpu. Code: double a = 3015.0;
