Hi,
I am trying to dump the final-most gimple (in ssa) file. My understanding is
that lto encodes GIMPLE IR in the bytestream of the object files and
accordingly I invoke PLUGIN_PASS_MANAGER_SETUP to embed my faux dummy pass
after 'pass_ipa_lto_finish_out'. Is ssa information available at the
'all_lto_gen_passes' stage?
Also, should I check for other properties (PROP_trees) and should I bother with
TODO_cleanup_cfg?
Error message:
cc1: fatal error: pass ‘ipa_lto_gimple_out’ not found but is referenced by new
pass ‘gimpleSSA_out’
Any help would be greatly appreciated.
Thank you.
Regards,
Karthik
