Stack Overflow online already has a lot of examples, but rarely involved in the 64-bit and operating system Linux-related, and recently just good enough to study this, so write a series of blog posts, one to help their memories, and also for more people to explore each other.RegisterThe X86-64 has 16 64-bit registers, respectively:%rax,%rbx,%rcx,%rdx,%esi,%edi,%rbp,%rsp,%r8,%r9,%r10,%r11,%r12,%r13,%r14,%r15. which%rax used as a function return value%R
windows has a lot of testing software, such as the famous 3DMark, PCMark, CineBenchR15, and so on, many players are accustomed to run the score by comparison, judge a product strength. However, a strange question arose.
The same model of notebook, a media given the 3DMark score is 6000, why users buy home measured results are only 5000? Do the media dare to make false propaganda?

CORTEX-M3 has universal register R0-R15 and some special function registers. R0-r12 is the most "common purpose", the vast majority of 16-bit instructions can only use R0-R7, while the 32-bit Thumb-2 instruction has access to all the universal registers. Special function registers must be accessed through a dedicated instruction.Universal Purpose Register R0-R7R0-R7 is called a low group register. All instructions are accessible, R8-r12 called High gr

remembered as v1~v8. If some registers in the register v1~v8 are used in the subroutine, the values of these registers must be saved when the subroutine enters, and the values of these registers must be restored before they are returned. In a thumb program, you can usually only use register R4~R7 to save local variables.
• Register R12 is used as the intermediate temporary register for the procedure call, which is recorded as IP. This usage rule is often used in connection code snippets between

Its value is calculated by the assembler, which is the 24 bit signed number, left two bits after the symbol extension to 32 bit, the valid offset is the 26 bit.

Subsequently, many media also sent to the i7-7700k of the first evaluation, in addition to this generation overclocking more powerful, performance promotion is really very limited, and there is
