cgraphbuild.c (compute_call_stmt_bb_frequency): Use proper ENTRY_BLOCK_PTR.
* cgraphbuild.c (compute_call_stmt_bb_frequency): Use proper ENTRY_BLOCK_PTR.
* cgraph.c (cgraph_clone_edge): Avoid freq_scale 0 to completely zero out all
callees.
* cgraphunit.c (verify_cgraph_node): Verify cgraph nodes for frequency and count match.
* ipa-inline.c (update_noncloned_frequencies): New function.
(cgraph_clone_inlined_nodes): Use it.
* tree-inline.c (copy_bb): Fix frequency scaling; output
diagnostic on frequency mismatches to dump file.
(initialize_cfun): Do not scale frequency; fix count scaling;
initialize entry and exit block frequencies; copy profile
info.
(copy_cfg_body): Use frequency_scale as argument;
fix count scaling.
(copy_body): Use frequency_scale as argument.
(expand_call_inline): Compute frequency scale and output diagnostic
to dump file.
(delete_unreachable_blocks_update_callgrah): Remove checking that
has to be done after edge redirection.
(tree_function_versioning): Update initialize_cfun and copy_body call.
