The LDR pseudo-directive is in the form of "Ldr rn,=expr". Here is an example of how to use it.COUNT EQU 0x40003100......LDR R1,=countMOV R0, #0STR R0,[R1]Count is a variable that we define, with the address 0x40003100. This definition method in assembly language is very common, if you use a single-chip computer, should be familiar with this usage.LDR R1,=count is the address of this variable of count, which is 0x40003100 put into R1.MOV R0, #0是将立即数0放到R0中. The last sentence, str r0,[r1] is a typ
6.3.6 Generating assembly instructions for "fetch address"In this section, let's discuss the translation of the following two intermediate directives:(1) Take address order For example (2) Object Clear 0 Directive For example Let's take an example to illustrate that for the initialization of the local array of arr in the 4th row of the figure 6.3.14, we can zero out the array of arr by 16 bytes of memory by the CLR intermediate instruction on line 11t
When configuring PHP5 to use MySQL as a database, many people think that as long as the php.ini to add extension=php_mysql.dll; instructions, it is unclear why many articles are recommended to add EXTENSION=PHP_ Mysqli.dll; an instruction.
Just check out the official latest PHP manual, which reads:
The following is a list of the built-in extension libraries:
PHP 5 (as of 5.0.4) has the following modifications. Added built-in: DOM,LIBXML,ICONV,SIMPLEXM

I have learned C language and C ++ for three years, but I still don't know much about Conditional compilation commands. I can see some excellent source code on the Linux platform, such as uC/OS-II used a lot of compilation instructions, MFC also used the Conditional compilation instructions, and now I learned some of the Conditional compilation instructions to ma

Before you start learning more complex concepts in later chapters. Let's take a look at some of the core parts of the language and see how to use them to write some very basic scripts (including only a few simple steps). Before we start learning more complex concepts in later chapter
