[Bug middle-end/99109] [9/10/11 Regression] ICE: Error reporting routines re-entered since r9-1948
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=99109 --- Comment #5 from CVS Commits --- The master branch has been updated by Jakub Jelinek : https://gcc.gnu.org/g:f72e3d8c9ffb81d25d4fdba10056cd2197e22d64 commit r11-7275-gf72e3d8c9ffb81d25d4fdba10056cd2197e22d64 Author: Jakub Jelinek Date: Thu Feb 18 09:45:19 2021 +0100 array-bounds: Fix up ICE on overaligned variables [PR99109] check_mem_ref builds artificial arrays for variables that don't have array type. The C standard says: "For the purposes of these operators, a pointer to an object that is not an element of an array behaves the same as a pointer to the first element of an array of length one with the type of the object as its element type." so it isn't completely wrong and does simplify the function. But, layout_type can fail if the size of the element type is not a multiple of its alignment (i.e. overaligned types) and we then ICE because of that. The following patch uses TYPE_MAIN_VARIANT in those cases instead, but only for the types that need it, as for the diagnostics it is better to use the typedef names etc. that were really used in the source if possible. 2021-02-18 Jakub Jelinek PR middle-end/99109 * gimple-array-bounds.cc (build_zero_elt_array_type): Rename to ... (build_printable_array_type): ... this. Add nelts argument. For overaligned eltype, use TYPE_MAIN_VARIANT (eltype) instead. If nelts, call build_array_type_nelts. (array_bounds_checker::check_mem_ref): Use build_printable_array_type instead of build_zero_elt_array_type and build_array_type_nelts. * g++.dg/warn/Warray-bounds-17.C: New test.

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=99109 --- Comment #3 from Jakub Jelinek --- array_bounds_checker::check_mem_ref certainly shouldn't try to pretend there is any ARRAY_TYPE that wasn't in the source if the type is overaligned (its size is not a multiple of the alignment).
