The compiler can remove them.
There may, of course,still be logical errors that the compiler cannot detect.
The compiler can reduce the expression(y+ 1)- 1 to y.
When I'm using Linux Mint 18.1 Serena,I realized that gcc compiler can not find stdio.
The expression compiler can determine the amount of memory required.
Use of an optimizing compiler tends to ensure that the executable program is optimized at least as much as the compiler can predict.
Obviously, a compiler can potentially do a better job using a broader view.
Due to type inference, the type of variables, function return values, andmany other expressions can typically be omitted, as the compiler can deduce it.
The GCC compiler can generate machine-code for a large variety of computer-architectures.
For example, given a function f(x, y) that adds x andy together, the compiler can infer that x and y must be numbers-since addition is only defined for numbers.
The compiler can often group instructions into sets of six that can execute at the same time.
However, on AMD64, 32 bit x86 applications may still benefit from a 64-bit recompile, due to the additionalregisters in 64-bit code, which a high-level compiler can use for optimization.
For example, a bug in a compiler can make it crash when parsing some large source file.
However, on the x86-64 platform,many x86 applications could benefit from a 64-bit recompile, due to the additional registers in 64-bit code and guaranteed SSE2-based FPU support, which a compiler can use for optimization.
The compiler can emit fast native code translations of JavaScript functions on the ARM, x86, and x86-64 platforms.
Special-purpose use If the software is compiled to be used on one or a few very similar machines, with known characteristics,then the compiler can heavily tune the generated code to those specific machines(if such options are available).
Anything the compiler can't understand, which in a normal language would result in a compilation error, is just skipped.
Any language can be implemented with a compiler or with an interpreter.[1] A combination of both solutions is also common: a compiler can translate the source code into some intermediate form(often called p-code or bytecode), which is then passed to an interpreter which executes it.
When the compiler can take maximum advantage of this, the processor can execute six instructions per clock cycle.
Depending on whether the compiler inlines functions across code in different languages, the compiler can do inlining on either a high-level intermediate representation(like abstract syntax trees) or a low-level intermediate representation.
A cross compiler can generate binary code for the user machine even if it has a different processor than the machine where the code is compiled.
The void-safe facility can be seen in a short re-work of the example code used above: some_attribute: detachable SOME_TYPE use_some_attribute-- Set value of some_attribute to'v'. do if attached some_attribute as l_attribute then do_something(l_attribute)end end do_something( a valueSOME_TYPE)-- Do something with'a_value'. do… doing something with'a_value'… end The code example above shows how the compiler can statically address the reliability of whether some_attribute will be attached or detached at the point it is used.
The condition 0== 0 is always true,so the compiler can replace the line marked(2) with the consequent, temp+= 0(which does nothing).
A compiler can thus make almost all the conversions from source code semantics to the machine level once and for all(i.e. until the program has to be changed) while an interpreter has to do some of this conversion work every time a statement or function is executed.
The code example above shows how the compiler can statically address the reliability of whether some_attribute will be attached or detached at the point it is used.
If a compiler can prove that a program is well-typed, then it does not need to emit dynamic safety checks, allowing the resulting compiled binary to run faster.
A combination of both solutions is also common: a compiler can translate the source code into some intermediate form(often called p-code or bytecode), which is then passed to an interpreter which executes it.
The Xtensa C/C++ compiler can freely intermix 32- or 64-bit FLIX instructions with the Xtensa processor's one-operation RISC instructions, which are 16 or 24 bits wide.
However, the compiler cannot use this information after an assignment to another variable(for example, in C,*y= 10) because it could be that*y is an alias of x.
Indeed the compiler cannot guess at which page a specific section is going to be printed, so when the table of contents is printed before the upcoming sections, it cannot set the page numbers.
