| Linux and Mac OS: | None |
| Windows: | /Qsfalign[n] /Qsfalign- |
| 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. | |
| /Qsfalign8 | Alignment occurs for functions with 8-byte aligned variables. |
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.
