# Qsfalign

Specifies stack alignment for functions. This option is deprecated and will be removed in a future release.

## Architecture Restrictions

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

## Syntax

Linux: | None

macOS: | None

Windows: | /Qsfalign[n]

## Arguments

n | Is the byte size of aligned variables. Possible values are:
8 | Specifies that alignment should occur for functions with 8-byte aligned variables. At this setting the compiler aligns the stack to 16 bytes if there is any 16-byte or 8-byte data on the stack. For 8-byte data, the compiler only aligns the stack if the alignment will produce a performance advantage.
16 | Specifies that alignment should occur for functions with 16-byte aligned variables. At this setting, the compiler only aligns the stack for 16-byte data. No attempt is made to align for 8-byte data.

## Default

/Qsfalign8 | Alignment occurs for functions with 8-byte aligned variables.

## Description

This option specifies stack alignment for functions. It lets you disable the normal optimization that aligns a stack for 8-byte data.

If you do not specify n, stack alignment occurs for all functions. If you specify /Qsfalign-, no stack alignment occurs for any function.
