What is the compiler option?

What is the compiler option?

Compilers options (− x on Linux, and /Qx on Microsoft Windows) control which instructions the compiler uses within a function, while the processor(…) clause controls creation of non-standard functions using wider registers (YMM or ZMM) for passing SIMD data for parameters and results.

What is compiler option in COBOL?

The INITIAL compiler option causes a program and all of its nested programs to behave as if the IS INITIAL clause was specified on the PROGRAM-ID paragraph. The INLINE option controls whether the inlining of procedures (paragraphs or sections) referenced by PERFORM statements in the source program is allowed.

How do you compile a COBOL program using JCL?

The following example shows the general format of JCL used to compile a program. The JOB statement indicates the beginning of a job. The EXEC statement specifies that the Enterprise COBOL compiler (IGYCRCTL) is to be invoked. This DD statement defines the data set where the Enterprise COBOL compiler resides.

What is compiler switch?

4.3 Compiler Switches The `gcc’ command accepts switches that control the compilation process. These switches are fully described in this section: first an alphabetical listing of all switches with a brief description, and then functionally grouped sets of switches with more detailed information.

What is fPIC option in GCC?

fPIC option in GCC enables the address of shared libraries to be relative so that the executable is independent of the position of libraries. This enables one to share built library which has dependencies on other shared libraries. fPIC stands for “force Position Independent Code”.

What is Ssrange compiler option?

SSRANGE generates code that checks whether subscripts, including ALL subscripts, or indexes try to reference areas outside the region of their associated tables. Each subscript or index is not individually checked for validity.

How do I compile and run a COBOL program in mainframe?

To run your COBOL program in TSO, compile and link-edit the program, and then run it in either with or without ISPF. You must compile and link-edit your COBOL program before you can run it in TSO. After your COBOL program compiles successfully, you can run it with JCL without ISPF.

How COBOL will compile and run JCL?

In the above example, RMODE instructs the compiler to use relative addressing mode in the program. The COBOL program is passed using SYSIN parameter and the copybook is the library used by the program in SYSLIB. This JCL produces the load module of the program as output which is used as the input to the execution JCL.

How does GCC compiler work?

After the file is preprocessed, gcc moves it to the compiler. The compiler turns each line in the preprocessed file into assembly language, which are instructions in English mnemonics that have strong one-to-one correspondence to the machine code that computers can read.

What is difference between fPIC and fPIC?

fPIC vs fpic fPIC: emits Position Independent Code without considering GOT restrictions. fpic: emits Position Independent Code considering GOT restrictions.

What is the meaning of fPIC?

The principle of Free, Prior and Informed Consent (FPIC) refers to the right of indigenous peoples to give or withhold their consent for any action that would affect their lands, territories or rights. “Free” ​means that indigenous peoples’ consent cannot be given under force or threat.

What is offset in COBOL?

The Length or Offset of the data item measured in 1-byte increments. The offset origins start at 1, unlike with other languages in which offsets might start at 0. The table item is not a data item, but some other string, such as a program label or paragraph name.

What is static and dynamic linking in COBOL?

In static linking, the called subroutine is link-edited into the calling program , while in dynamic linking, the subroutine & the main program will exist as separate load modules. You choose static/dynamic linking by choosing either the DYNAM or NODYNAM link edit option.
