ion specifies that everything will look exactly the same > as if it were a POD with the same members declared in the same order. I don't think that's true. I believe the non-POD must be passed in memory, but GCC would be permitted to pass the POD in a register if it preferred. The layout is defined by the C++ ABI, but not the argument passing conventions. -- Daniel Jacobowitz CodeSourcery

Re: cannot pass objects of non-POD type

2007-10-25 Thread Daniel Jacobowitz
Ds still get passed in registers if the layout-equivalent POD would, unless there is a non-trivial copy constructor or destructor; there are non-PODs without those. Sorry for the confusion. -- Daniel Jacobowitz CodeSourcery

riables, unless you can explain to the debugger that the variable is currently in both locations - this has been discussed but AFAIK there is no representation for it yet. Changing the memory location won't change the next operation that thinks it's in the register. Changing the registe
