GCC’s Rust compiler has been updated to emit block-scope Drop calls through TRY_FINALLY_EXPR. This change ensures that destructors are correctly invoked when blocks are exited, even if cleanup code is involved. A new function, Context::pop_block_with_cleanup, is introduced to facilitate this, allowing cleanup logic to be passed as part of the block-popping operation.
