DescriptionPPAPI regression test for NaCl x86-32 IRT stack alignment sensitivity
The bug with IRT stack alignment sensitivity can manifest in two ways.
The issue of the stack being aligned properly at callbacks from the
IRT is tested on the NaCl side (irt_stack_alignment test). The other
issue is alignment-sensitive SSE instructions being used to copy
16-byte arguments from the stack, assuming they will be properly
aligned on the stack. That situation only comes up with the PPAPI
interfaces that use a 16-byte argument type such as PP_Var. So test
that case here.
