I’m woking on TARGET_PROMOTE_FUNCTION_MODE for csky, and now there’s some
confusion.
For csky, the “POMOTE_MODE” is:
qi/hi -> si
the code is
#define PROMOTE_MODE(MODE, UNSIGNEDP, TYPE) \
if (GET_MODE_CLASS (MODE) == MODE_INT \
&& GET_MODE_SIZE (MODE) < UNITS_PER_WORD) \
(MO
When I was adding pipeline to my backend, some instructions needed to be
fused and I found that there was no suitable interface to implement my
requirements.
My hope is that
1. Do instruction scheduling and combine any two instructions, and sometimes
the two instructions can be treated as 1 wh
oviding an interface to fusing instructions via
scheduling
