<p>Specify the desired alignment of the stack pointer. </p>
|
|
<p><b>BIGGEST_ALIGNMENT</b> provides the largest alignment ever used for any data type on the target machine. This is normally identical to desired stack alignment. Align stack pointer for directly invoked functions.</p>
|
|
<p>The stack needs to be aligned to L4_STACK_ALIGN for being able to access certain data on the stack. On x86/AMD64, a function call is performed using the 'call' instruction decrementing the stack pointer and writing the return address onto the stack. The called function considers this when adapting the stack pointer after function entry. If the called function was not invoked by a 'call' instruction, the stack pointer is actually off by a machine word leading to stack alignment issues when executing SSE instructions.</p>
|
|
<p>This function fixes the stack pointer for directly invoked functions. For architectures not automatically pushing the stack pointer during a function call, just enforce the L4_STACK_ALIGN alignment. </p>
