Static chain support in ipa-modref
Teach ipa-modref about the static chain that is, like
retslot, a hiden argument. The patch is pretty much symemtric to what
was done for retslot handling and I verified it does the intended job
for Ada LTO bootstrap.
gcc/ChangeLog:
* gimple.c (gimple_call_static_chain_flags): New function.
* gimple.h (gimple_call_static_chain_flags): Declare
* ipa-modref.c (modref_summary::modref_summary): Initialize
static_chain_flags.
(modref_summary_lto::modref_summary_lto): Likewise.
(modref_summary::useful_p): Test static_chain_flags.
(modref_summary_lto::useful_p): Likewise.
(struct modref_summary_lto): Add static_chain_flags.
(modref_summary::dump): Dump static_chain_flags.
(modref_summary_lto::dump): Likewise.
(struct escape_point): Add static_cahin_arg.
(analyze_ssa_name_flags): Use gimple_call_static_chain_flags.
(analyze_parms): Handle static chains.
(modref_summaries::duplicate): Duplicate static_chain_flags.
(modref_summaries_lto::duplicate): Likewise.
(modref_write): Stream static_chain_flags.
(read_section): Likewise.
(modref_merge_call_site_flags): Handle static_chain_flags.
* ipa-modref.h (struct modref_summary): Add static_chain_flags.
* tree-ssa-structalias.c (handle_rhs_call): Use
gimple_static_chain_flags.
gcc/testsuite/ChangeLog:
