Setting breakpoints in optimized instructions

A computer system for obtaining up-to-date values of variables at a breakpoint during a debugging session of an optimized software code comprising:

• a processor;
• and memory communicatively coupled to the processor, wherein the memory is encoded within instructions, wherein the instructions when executed on the processor,
• comprise in response to a command that requests setting a breakpoint at a line in a module, determining whether a snapshot instruction exists before a machine instruction that implements a source statement at the line, wherein the snapshot instruction when executed by the processor stores a value of a variable referenced by the module from a register to a location in the memory that represents the variable, if the snapshot instruction exists before the machine instruction that implements the source statement at the line, setting the breakpoint at the machine instruction that implements the source statement at the line, and if the snapshot instruction does not exist before the machine instruction that implements the source statement at the line, recompiling the module to add the snapshot instruction before the machine instruction that implements the source statement.
