Abstract

PURPOSE:To omit the correction of an optimum object skeleton for each device type by obtaining each device type through a system, choosing an optimum object skeleton for each device type out of a device type-based object skeleton table storing previously the object skeletons, and generating an object program. CONSTITUTION:A code generating part 4 shifts the control once and at first, calls out a device type acquiring means 1 in order to acquire the device types through a system, then inputs an intermediate object program 5. If the input is not through yet with the whole program 5, an optimum object skeleton of each device type is obtained via a device type-based object skeleton table 3 based on the device type acquired by the means 1. Then the read program 5 is outputted as an object program 6 via an acquired optimum object skeleton. Thus no correction is required to the optimum object for each device type.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an optimal object generation processing method for an object program output by a compiler in a computer system.

[Conventional technology]

Conventionally, this type of optimal object generation processing method has been developed because there are multiple models of one O8 (operating system), and each model has good execution performance and bad execution performance for the same hardware instruction, and instruction set. When there are different types of machines, a method is used in which the object skeleton defined in a code generator such as a compiler is changed to the optimal object skeleton for each model and the object is generated.

[Problem to be solved by the invention]

The conventional optimal object generation method described above generates objects by changing the optimal object skeleton for each model, so the optimal object generation method of the present invention requires modification of the optimal object for each model. The processing method includes a model acquisition means that transfers control only once at the beginning and obtains the model type from the system in the processing of a code generation unit such as a compiler in a system where one O8 (operating system) has multiple models;
a model-specific object skeleton table having a plurality of model-specific object skeletons; an object skeleton obtaining means for obtaining an optimal object skeleton from the model-specific object skeleton table based on the model type obtained from the model-specific object skeleton table; and a code generation unit that generates an object program from the object program according to the optimal object skeleton.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a configuration diagram of an embodiment of the present invention. In this embodiment, control is first transferred only once, and a model acquisition means 1 that obtains the model type, a model-specific object skeleton that stores a model-specific object skeleton, and a model-specific object skeleton that stores a model-specific object skeleton. Object skeleton acquisition means 2 obtains an object skeleton corresponding to the model type from table 3, object skeleton by model table 3, and intermediate object program 5 is input, and from the optimal object skeleton for each model obtained from object skeleton acquisition means 2. The code generation section 4 outputs an object program 6.

FIG. 2 shows the operation flow of the code generation unit 4. Referring to FIG. 2, the code generation unit 4 first transfers control only once and calls the model acquisition means 1 to acquire the model type from the system. (step 21), and inputs the intermediate object program 5 (step 21). It is determined whether all inputs to the intermediate object program 5 have been completed (step 23). If not completed, the optimal object skeleton for each model is obtained from the model-specific object skeleton table 3 based on the model type obtained by the model acquisition means 1 (step 24). Output the read intermediate object skeleton program 5 as an object program 6 using the obtained optimal object skeleton (
Step 25). Steps 22 to 25 are repeated until the input is completed in step 23.

〔Effect of the invention〕

As explained above, the present invention obtains the type of each model from the system, selects the optimal object skeleton for each model from the model-specific object skeleton table stored in advance, and generates an object program. This has the effect that it becomes unnecessary to modify the optimal object skeleton for each model.
