------- Comment #2 from hp at gcc dot gnu dot org 2008-09-02 00:47 -------
Honza, why is tree-inline.c:initialize_cfun not calling
allocate_struct_function and *then* change whatever elements need changing?
There's no comment to reveal the reason. Now, you're just allocating a cleared
area and doing a shallow-copy, which causes the clone to have e.g. the same
cfun->machine. Badness results.
This is a tree-optimization bug, not a target bug.
