[Bug tree-optimization/42108] [4.4/4.5 Regression] 50% performance regression

[tkoenig at gcc dot gnu dot org]

------- Comment #36 from tkoenig at gcc dot gnu dot org  2009-12-15 07:09 -------
If it is any help, code which traps for a do loop is illegal Fortran,
so the compiler may do anything in this case anyway.

Is there a function like
__builtin_i_dont_care_if_this_traps_or_not_if_it_traps_its_the_users_fault ?
