Hi,
I've been working on a SH specific RTL pass and just adapted it to the
new pass handling. One thing that bugged me was pass registration. How
about adding an overload for 'register_pass' as in the attached patch?
Registering a pass is then as simple as:
register_pass (make_new_ifcvt_sh (g, false, "ifcvt1_sh"),
PASS_POS_INSERT_AFTER, "ce1", 1);
Tested with make all-gcc.
Cheers,
Oleg
gcc/ChangeLog:
* passes.c (register_pass): Add overload.
* tree-pass.h (register_pass): Forward declare it.
Add comment.
