--- Comment #7 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Richard Biener <rgue...@gcc.gnu.org>: https://gcc.gnu.org/g:604459a09585314841cdce4698893c656481691b commit r12-4182-g604459a09585314841cdce4698893c656481691b Author: Richard Biener <rguent...@suse.de> Date: Tue Oct 5 09:28:20 2021 +0200 More .DEFERRED_INIT expansion rework This avoids looking at the type size and instead uses the size as passed to .DEFERRED_INIT to determine the size of the non-MEM to be initialized. It also arranges for possibly poly-int inits to always use zero-initialization rather than not initializing and when we need to pun puns the LHS instead of the constant value. That correctly initializes the variable-size typed array in the testcase for PR102285 and the SVE vector in PR102587 where for the testcase I needed to add a SVE capable -march as to not ICE later. 2021-10-05 Richard Biener <rguent...@suse.de> PR middle-end/102587 PR middle-end/102285 * internal-fn.c (expand_DEFERRED_INIT): Fall back to zero-initialization as last resort, use the constant size as given by the DEFERRED_INIT argument to build the initializer. * gcc.target/aarch64/sve/pr102587-1.c: Add -march=armv8.3-a+sve. * gcc.target/aarch64/sve/pr102587-2.c: Likewise.
