Hi,
I have some questions about the frame_info and stack of variable length type:
In the current gcc framework, it seems that 'poly_uint64(coeff0, coeff1)'
is used to calculate 'cfun->machine->frame', but only one variable length
type(vector) can be processed.
If I want to add a new variable length type, such as matrix type,
how can I handle its frame_info and stack? In other words, how to handle the
frame_info and stack of various variable length MACHINE_MODE.
Thanks.
