The GCC compiler’s SSA verification process has been improved to catch errors earlier. Previously, passes that failed to call update_stmt for symbols needing renaming would delay the error detection to later passes. This change ensures that such failures are now caught immediately during SSA operand verification, showing the specific statement responsible.
