--- Comment #12 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Andrew Pinski <pins...@gcc.gnu.org>: https://gcc.gnu.org/g:8819419ba1d397c0444d89079ec16657a09914fb commit r12-2473-g8819419ba1d397c0444d89079ec16657a09914fb Author: Andrew Pinski <apin...@marvell.com> Date: Tue Jul 20 11:25:43 2021 -0700 Fix PR 10153: tail recusion for vector types. The problem here is we try to an initialized value from a scalar constant. For vectors we need to do a vect_dup instead. This fixes that issue by using build_{one,zero}_cst instead of integer_{one,zero}_node when calling create_tailcall_accumulator. Changes from v1: * v2: Use build_{one,zero}_cst and get the correct type before. OK? Bootstrapped and tested on aarch64-linux-gnu with no regressions. gcc/ChangeLog: PR tree-optimization/10153 * tree-tailcall.c (create_tailcall_accumulator): Don't call fold_convert as the type should be correct already. (tree_optimize_tail_calls_1): Use build_{one,zero}_cst instead of integer_{one,zero}_node for the call of create_tailcall_accumulator. gcc/testsuite/ChangeLog: PR tree-optimization/10153 * gcc.c-torture/compile/pr10153-1.c: New test. * gcc.c-torture/compile/pr10153-2.c: New test.
