Embodiment Construction

[0043] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0044] The test scheme realized by the present invention needs a reference compiler, and the first choice should be the PICC compiler of Microchip Company, but the runtime library (PICC RunTime Lib) called by the PICC compiler is different from the runtime library (CSCC RunTime Lib) of Chipsea. ) are different, resulting in uncertain differences in the generated object code. The current feasible technical solution is: according to the characteristics of our chip core, embed assembly in the C source file, and compile the HEX file through CSCC (C compiler), CSASM (assembler) and CSLINK (linker), Com...

Abstract

The invention discloses a method for automatically testing a C compiler. According to the method, an assembly is embedded into a C source file, and an HEX file obtained through the C compiler, an assembler and a linker in a compiling mode is combined with a lower computer hardware simulator to verify an expected result, so that the aim of verifying a CSCC compiler is achieved. Automatic testing is quickly achieved through the method, the correctness of a tool chain of the whole C compiler is indirectly tested by utilizing the whole IDE development environment, and the problems that the C compiler is used for compiling manually, simulation setting is tedious and the operation speed is low are solved.

Description

technical field [0001] The invention belongs to the technical field of C compilers, in particular to a method for fast automatic testing of chip C compilers. Background technique [0002] The chip integrated development environment (IDE Integrated Development Environment) plays an important role as a platform for manufacturers to develop chips. IDE software generally includes C compilers and assemblers. With the rapid demand of the chip market, the development of traditional assemblers Efficiency has been difficult to meet, and now C compiler plays a key role in the embedded field. In the process of chip manufacturers developing C compilers, a problem will be involved: how to verify the correctness of C compilers and related tool chains (C compilers, assemblers, linkers). [0003] When the compiler test mode includes the traditional compiler test mode and the Ctcgen tool test mode, the traditional compiler test mode: according to the syntax, design the test program generato...
