In the computer, the CPU speed is much faster than the memory speed, the compiler should make the best use of register resources, reduce unnecessary access to memory, thereby increasing the compiler generated by the assembly code run speed. In the intermediate code generation phase, the UCC compiler holds a temporary variable T to hold the shape as "t:a+b;" The value of the common subexpression of the assembly code generation, the

6.1 Introduction to assembly code generationAfter lexical analysis, parsing, semantic checking, and intermediate code generation, we finally came to the "target code generation phase" because the UCC compiler's target code was the 32-bit x86 assembly code, so we called this chapter "assembly code Generation". Most of the source code in the UCC compiler is for Windows and Linux platforms, but the default ass

C compiler profiling _ 5.2.3 intermediate code generation and optimization _ access array elements and struct members through "offset" Section 5.2.3 accesses array elements and struct members through "offset" In the previous section, we introduced the access to "array elements and struct members". We use the "base address + offset" mode to calculate the address of the memory unit. For the array element arr2 [I] [2], the array index value I is a variable, and the corresponding address must be exp

6.3.1 The main process of generating assembly code from intermediate directivesIn this section, we can focus on "how to translate an intermediate code into assembly code". The intermediate code for the UCC compiler is a four-tuple, including operators and 3 operands, as shown below.Of course, some intermediate code only need to use opcode and DST, for example, the unconditional jump instruction "goto BB2;" There is no need for SRC1 and SRC2. To facili

the constant constant, without regard to (expression). Let's take a look at how the UCC compiler handles strings, as shown in 4.2.8.Figure 4.2.8 String StringLiteral Figure 4.2.8 the 1th to 11th row of HELLO.C has 5 strings, visible from line 15th to 20th, except for the "123456" that initializes the global array buf[], the UCC compiler names several other strings. Str0,. str1,. STR2 and. Str3. For the st

Unified Communication is not the same as unified Interaction UC is continuously warming up, but can it solve the problem of communication disconnection? The new system must take UC further to support real unified interaction. The use of unified communication and collaboration (UCC) or Unified Communication as a service (uCaaS) is expected to increase rapidly in the next few years, because these technologies can integrate multiple channels into a sin
