[PR 78365] Prudent type handling in IPA VR-prop
2017-01-09 Martin Jambor <mjambor@suse.cz>
PR ipa/78365
PR ipa/78599
* ipa-prop.h (ipa_jump_func): Swap positions of vr_known and m_vr.
* ipa-cp.c (ipa_vr_operation_and_type_effects): New function.
(propagate_vr_accross_jump_function): Use the above function for all
value range computations for pass-through jump functions and type
converasion from explicit value range values.
(ipcp_propagate_stage): Do not attempt to deduce types of formal
parameters from TYPE_ARG_TYPES.
* ipa-prop.c (ipa_write_jump_function): Remove trailing whitespace.
(ipa_write_node_info): Stream type of the actual argument.
(ipa_read_node_info): Likewise. Also remove trailing whitespace.
testsuite/
* gcc.dg/torture/pr78365.c: New test.
