------- Comment #7 from jakub at gcc dot gnu dot org 2009-05-20 14:32 ------- For all involved strings being non-array CHAR with length 1 I fail to see why normal SWITCH_EXPR isn't used instead (though that would just be an optimization).
The middle-end can't know the _gfortran_select_string function will never return numbers bigger than the size of the jump table it is called with, so the Fortran FE should help it. If the table contains a default label, it should use a default: case label instead of corresponding number, and if there is no case label, but all possible strings are covered, it can pick a random case label as the default. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=40206
