Arrangements described herein relate to inserting implicit sequence points into computer program code to support debug operations. Optimization of the computer program code can be performed during compilation of the computer program code and, during the optimization, implicit sequence points can be inserted into the computer program code. The implicit sequence points can be configured to provide virtual reads of symbols contained in the computer program code when the implicit sequence points are reached during execution of the computer program code during a debug operation performed on the computer program code after the computer program code is optimized and compiled.
