Compiling source code includes receiving, by an optimizing compiler from a debugger, a variable value modification profile that specifies locations in the source code at which variable values modified during a debug session; compiling the source code, including: inserting snapshots at one or more of the locations in the source code at which variable values were modified, each snapshot including a breakpoint; and only for each snapshot at a location in the source code at which variable values were modified: inserting, between the breakpoint and remaining source code at the location of the snapshot, a module of computer program instructions that when executed retrieves a current value of a variable and stores the current value in a register; and recording the location of each inserted snapshot; and providing, to the debugger by the optimizing compiler, the recorded locations of each inserted snapshot along with the compiled source code. |
