For reasons too complicated to explain here, I have the need to run a x86 GCC-compiled Linux program on a platform that is a subset of x86. This platform does not have the %gs register,
What are the best settings for stuff like MXCSR? Which rounding mod开发者_运维技巧e is fastest? On what processors? Is it faster to enable signalling NaNs so I get informed when a computation results
I have two vectors of 4 integers each and I\'d like to use a SIMD command to compare them (say generate a result vector where each ent开发者_JAVA技巧ry is 0 or 1 according to the result of the compari
I need to use some x86 instructions that have no GCC intrinsics, such as BSF and BSR. With GCC inline assembly, I can write something like the following
I want to draw a colored line in asm. I have to use AT&T syntax, on an x86 intel linux unit. I got pretty far already, but I\'d like to know how to enter VGA-mode, or Mode-X, and how to put a pix
I was immediately suspicious of the crash.A Floating Point Exception in a method whose only arithmetic was a \"divide by sizeof(short)\".
I am in the process of trying to compile an old project on my modern machine. I know this old project used an old (2.x) version of GCC/GAS so I need to clean it up so that I can compile it with a curr
What is the most efficient way to change the rounding mode* of IEEE 754 floating point numbers?A portable C function would be nice, but a solution that uses x86 assembly is ok too.
I have googled enough but could not figure out what the bracket () means. Also, I see some syntax as movl 8(%ebp), %eax
I am trying to convert an assembly prog开发者_StackOverflowram I wrote into NULL-free shellcode. However, I am unsure how to go about this for certain instructions.
