In most cases for the large/huge _BitInt bitfield stores the code uses bitfield representatives, which are typically arrays of chars, but if the bitfield starts at byte boundary on big endian, the code uses as nlhs in lower_mergeable_store COMPONENT_REF of the bitfield FIELD_DECL instead, which is fine for the limb accesses, but when used for the most significant limb can result in invalid BIT_FIELD_REF because the first operand then has BITINT_TYPE and usually VOIDmode. The following patch adds a helper method for the 4 creatikons of BIT_FIELD_REF which when needed adds a VIEW_CONVERT_EXPR. 2024-03-16 Jakub Jelinek <jakub@redhat.com> PR tree-optimization/114329 * gimple-lower-bitint.cc (struct bitint_large_huge): Declare build_bit_field_ref method.
