Add comment to indicate tail recursion My previous change removed an unreachable break; there (an unreachable continue; would have been more to the point). The following re-adds a comment explaining that WALK_SUBEXPR_TAIL does not fall through but tail recurses. 2021-11-30 Richard Biener <rguenther@suse.de> gcc/fortran/ * frontend-passes.c (gfc_expr_walker): Add comment to indicate tail recursion.
