falign-stack

Tells the compiler the stack alignment to use on entry to routines. This option is deprecated and will be removed in a future release. This feature is only available for ifort.

Architecture Restrictions

Only available on IA-32 architecture. IA-32 support is deprecated and will be removed in a future release.

Syntax

-falign-stack=mode

macOS:

None

Windows:

None

Arguments

mode

Is the method to use for stack alignment. Possible values are:

assume-4-byte	Tells the compiler to assume the stack is aligned on 4-byte boundaries. The compiler can dynamically adjust the stack to 16-byte alignment if needed.
maintain-16-byte	Tells the compiler to not assume any specific stack alignment, but attempt to maintain alignment in case the stack is already aligned. The compiler can dynamically align the stack if needed. This setting is compatible with gcc.
assume-16-byte	Tells the compiler to assume the stack is aligned on 16-byte boundaries and to continue to maintain 16-byte alignment. This setting is compatible with gcc.

Default

-falign-stack=assume-16-byte

The compiler assumes the stack is aligned on 16-byte boundaries and continues to maintain 16-byte alignment.

This option tells the compiler the stack alignment to use on entry to routines.
