Dump final -most gimp le (with s sa) using the plugin option‏‏

[karthik duraisami <kdconstant at hotmail dot com>]

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
