--- Comment #4 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Siddhesh Poyarekar <siddh...@gcc.gnu.org>: https://gcc.gnu.org/g:0573a0778af88e805f7630ac8640ecd67d692665 commit r13-5382-g0573a0778af88e805f7630ac8640ecd67d692665 Author: Siddhesh Poyarekar <siddh...@gotplt.org> Date: Thu Jan 26 07:07:03 2023 -0500 tree-optimization/108522 Use component_ref_field_offset Instead of using TREE_OPERAND (expr, 2) directly, use component_ref_field_offset instead, which does scaling for us. The function also substitutes PLACEHOLDER_EXPRs but it is not relevant for tree-object-size. gcc/ChangeLog: PR tree-optimization/108522 * tree-object-size.cc (compute_object_offset): Make EXPR argument non-const. Call component_ref_field_offset. gcc/testsuite/ChangeLog: PR tree-optimization/108522 * gcc.dg/builtin-dynamic-object-size-0.c (DEFSTRUCT): New macro. (test_dynarray_struct_member_b, test_dynarray_struct_member_c, test_dynarray_struct_member_d, test_dynarray_struct_member_subobj_b, test_dynarray_struct_member_subobj_c, test_dynarray_struct_member_subobj_d): New tests. (main): Call them. Signed-off-by: Siddhesh Poyarekar <siddh...@gotplt.org>
