I'm not sure what you mean. The expression array[i+1] compiles to

MULT_EXPR shows up in array indexing, since the index is multiplied by
the size of the element; gcc c

This patch adds support for array indexing (i.e. operator []) in lock
expressions. The current version of gcc seems to emit these as
expressions involving pointer arithmetic, so we update
get_canonical_lock_expr() to handle such expressions.
Bootstrapped and passed gcc regression testsuite on
x8
