Give the target more control over ARRAY_TYPE modes
So far we've used integer modes for LD[234] and ST[234] arrays. That doesn't scale well to SVE, since the sizes aren't fixed at compile time (and even if they were, we wouldn't want integers to be so wide). This patch lets the target use double-, triple- and quadruple-length vectors instead. 2018-01-13 Richard Sandiford <richard.sandiford@linaro.org> Alan Hayward <alan.hayward@arm.com> David Sherwood <david.sherwood@arm.com> gcc/ * target.def (array_mode): New target hook. * doc/tm.texi.in (TARGET_ARRAY_MODE): New hook. * doc/tm.texi: Regenerate. * hooks.h (hook_optmode_mode_uhwi_none): Declare. * hooks.c (hook_optmode_mode_uhwi_none): New function. * tree-vect-data-refs.c (vect_lanes_optab_supported_p): Use targetm.array_mode. * stor-layout.c (mode_for_array): Likewise. Support polynomial type sizes. Co-Authored-By: Alan Hayward <alan.hayward@arm.com> Co-Authored-By: David Sherwood <david.sherwood@arm.com> From-SVN: r256617
