[patch, arm] align saved FP regs on stack

2014-11-14 Thread Sandra Loosemore
On ARM targets, the stack is aligned to an 8-byte boundary, but when saving/restoring the VFP coprocessor registers in the function prologue/epilogue, it is possible for the 8-byte values to end up at locations that are 4-byte aligned but not 8-byte aligned. This can result in a performance pe
