2017-10-23Convert STARTING_FRAME_OFFSET to a hookRichard Sandiford84-302/+370
I took the documentation of the FRAME_GROWS_DOWNWARD behaviour from the version that was in most header files, since the one in the manual seemed less clear. The patch deliberately keeps FIRST_PARM_OFFSET(FNDECL) in microblaze_starting_frame_offset; this seems to be a port-local convention and takes advantage of the fact that FIRST_PARM_OFFSET doesn't read FNDECL. 2017-10-23 Richard Sandiford <richard.sandiford@linaro.org> gcc/ * target.def (starting_frame_offset): New hook. * doc/tm.texi (STARTING_FRAME_OFFSET): Remove in favor of...

2017-10-22Make more use of GET_MODE_UNIT_PRECISIONRichard Sandiford6-31/+54
This patch is like the earlier GET_MODE_UNIT_SIZE one, but for precisions rather than sizes. There is one behavioural change in expand_debug_expr: we shouldn't use lowpart subregs for non-scalar truncations, since that would just reinterpret some of the scalars and drop the rest. (This probably doesn't trigger in practice.) Using TRUNCATE is fine for scalars, since simplify_gen_unary knows when a subreg can be used. 2017-10-22 Richard Sandiford <richard.sandiford@linaro.org> Alan Hayward <alan.hayward@arm.com> David Sherwood <david.sherwood@arm.com> gcc/ * cfgexpand.c (expand_debug_expr): Use GET_MODE_UNIT_PRECISION.
