On the x86-64 architecture, two registers have a special purpose: FS and GS. In linux 2.6.*, the FS register seem to be used to s开发者_高级运维tore thread-local information.
If I have a multiprocessor setup and two threads that access the same memory (let\'s say the same actual byte or word, not only \"the same area\"), does this cause errors by itself?
int main(int argc, char* argv[]) { return 0; } what\'s the shortest assembly example to do the same that can be compiled into an executable by gcc?
For example, how to prepare parameters for this syscall sys_wait4: asmlinkage long sys_wait4(pid_t pid,unsigned int __user *stat_addr, int options, struct rusage __user *ru)
I can\'t find a dedicated official website to search for such information . For 开发者_StackOverflowexample,if I want to do exit,how should I do it with syscall introduced in x86_64?
Here is the text in LLVM\'s doc \"langref\": \"cc 10\" - GHC convention This calling convention has been implemented specifically for use by the Glasgow Haskell Compiler (GHC). It passes everything
Is it possible to use the new SSE registers from Visual Studio 2010 inline assembler? If so, how and what else conditions must be satisfied? I don\'t know for example if new registers are av开发者_JAV
From past readings it seems most 32 bit drivers won\'t work on 64 bit. At a purely conceptual level, I see a 64 bit machine as having extra \'room\' when using开发者_开发问答 32 bit drivers so am try
The (Microsoft) x64 calling convention states: The arguments are passed in registers RCX, RDX, R8, and R9. If the arguments are float/double, they are passed in XMM0L, XMM1L, XMM2L, and XMM3L.
How do you determine if the computer you are on is a 32-bit m开发者_开发问答achine or a 64-bit machine?
