sigsetjmp: store temporaries in jmp_buf rather than on stack.
2012-11-18fix powerpc asm not to store data in volatile space below stack pointerRich Felker-8/+8
it's essential to decrement the stack pointer before writing to new stack space, rather than afterwards. otherwise there is a race condition during which asynchronous code (signals) could clobber the data being stored. it may be possible to optimize the code further using stwu, but I wanted to avoid making any changes to the actual stack layout in this commit. further improvements can be made separately if desired.
