poly_int: PUSH_ROUNDING
PUSH_ROUNDING is difficult to convert to a hook since there is still a lot of conditional code based on it. It isn't clear that a direct conversion with checks for null hooks is the right thing to do. Rather than untangle that, this patch converts all implementations that do something to out-of-line functions that have the same interface as a hook would have. This should at least help towards any future hook conversion. 2018-01-03 Richard Sandiford <richard.sandiford@linaro.org> Alan Hayward <alan.hayward@arm.com> David Sherwood <david.sherwood@arm.com> gcc/ * config/cr16/cr16-protos.h (cr16_push_rounding): Declare. * config/cr16/cr16.h (PUSH_ROUNDING): Move implementation to... * config/cr16/cr16.c (cr16_push_rounding): ...this new function. * config/h8300/h8300-protos.h (h8300_push_rounding): Declare. * config/h8300/h8300.h (PUSH_ROUNDING): Move implementation to... * config/h8300/h8300.c (h8300_push_rounding): ...this new function. * config/i386/i386-protos.h (ix86_push_rounding): Declare. * config/i386/i386.h (PUSH_ROUNDING): Move implementation to... * config/i386/i386.c (ix86_push_rounding): ...this new function. * config/m32c/m32c-protos.h (m32c_push_rounding): Take and return a poly_int64. * config/m32c/m32c.c (m32c_push_rounding): Likewise. * config/m68k/m68k-protos.h (m68k_push_rounding): Declare. * config/m68k/m68k.h (PUSH_ROUNDING): Move implementation to... * config/m68k/m68k.c (m68k_push_rounding): ...this new function. * config/pdp11/pdp11-protos.h (pdp11_push_rounding): Declare. * config/pdp11/pdp11.h (PUSH_ROUNDING): Move implementation to... * config/pdp11/pdp11.c (pdp11_push_rounding): ...this new function. * config/stormy16/stormy16-protos.h (xstormy16_push_rounding): Declare. * config/stormy16/stormy16.h (PUSH_ROUNDING): Move implementation to... * config/stormy16/stormy16.c (xstormy16_push_rounding): ...this new function. * expr.c (emit_move_resolve_push): Treat the input and result of PUSH_ROUNDING as a poly_int64.
