◆ update_call_stmt_hash_for_removing_direct_edge()

We always maintain first direct edge in the call site hash, if one exists. E is going to be removed. See if it is first one and update hash accordingly. INDIRECT is the indirect edge of speculative call. We assume that INDIRECT->num_speculative_call_targets_p () is already updated for removal of E.

◆ verify_speculative_call()
|
static |
Disable warnings about missing quoting in GCC diagnostics for the verification errors. Their format strings don't follow GCC diagnostic conventions and the calls are ultimately followed by one to internal_error.
Verify consistency of speculative call in NODE corresponding to STMT and LTO_STMT_UID. If INDIRECT is set, assume that it is the indirect edge of call sequence. Return true if error is found. This function is called to every component of indirect call (direct edges, indirect edge and refs). To save duplicated work, do full testing only in that case.
