TCC document translation-1. Introduction

1. Introduction Tinycc (aka TCC) is a small but hyper fast C compiler. unlike other C compilers, it is meant to be self-relying: you do not need an external handler er or linker because TCC does that for you. TCC compiles soFastThat even for big projectsMakefileS may not be necessary. TCC not only supports ansi c, but also most of the new ISO c99 standard and upgrade gnuc extensions including inline assembly. TCC can also be used to makeC scripts, I.

UTF-8, gb2312, gb18030, GBK and big5 character set encoding range of specific instructions

code unit size is equivalent to the number of digits in a specific encoding method:UTF-8: code units in a UTF-8 are composed of eight digits; In a UTF-8, each code point is often mapped to multiple code units because of small code units. The code points are mapped to one, two, three, or four code units;UTF-16: the code units in the UTF-16 are composed of 16 bits; the size of the UTF-16's code units is twice the size of the 8-bit code units. Therefore, code points with a scalar value less than U

What is the usage and definition of PHP array_pop () function? The Array_pop () function is one of the PHP array functions, and his role is to delete the last element in the array (out of the stack). PS: Stack, aka stacks, is a linear table with constrained operations. The limitation is that only one end of the table is allowed to insert and delete operations. This end is called the top of the stack, and the opposite end is called the bottom of the st

Security problems in 3G Mobile Station Main-call access process

This paper analyzes the security problems in the current 3G reverse link call and call process, and discusses the relationship between MS and BS, such as AKA, signaling integrity protection, data confidentiality and intrusion detection. In addition, security and mobility management are combined appropriately in the discussion, and some new ideas and solutions are put forward according to the security problems in practical application. 1 Preface The

concept, such as Memcache, Hibernate, Tair, etc. have similar concepts.For different business scenarios, different concurrency control methods should be chosen. Therefore, the optimistic concurrency control and pessimistic concurrency control should not be understood narrowly as the concept in DBMS, not to confuse them with the locking mechanism (row, table, exclusive, shared) provided in the data. In fact, in DBMS, pessimistic lock is implemented by using the lock mechanism provided by the dat
