fzero-initialized-in-bss, Qzero-initialized-in-bss

Determines whether the compiler places in the DATA section any variables explicitly initialized with zeros. This feature is only available for ifort.

Syntax

Linux:

-fzero-initialized-in-bss

-fno-zero-initialized-in-bss

macOS:

-fzero-initialized-in-bss

-fno-zero-initialized-in-bss

Windows:

/Qzero-initialized-in-bss

/Qzero-initialized-in-bss-

Arguments

None

Default

-fno-zero-initialized-in-bss
or /Qzero-initialized-in-bss-

Variables explicitly initialized with zeros are placed in the BSS section. This can save space in the resulting code.

Description

This option determines whether the compiler places in the DATA section any variables explicitly initialized with zeros.

If option -fno-zero-initialized-in-bss (Linux* and macOS*) or /Qzero-initialized-in-bss- (Windows*) is specified, the compiler places in the DATA section any variables that are initialized to zero.
