US 2008/0178160 A1 · Protecting code from breakpoints

Abstract

A computer system and storage medium that, in an embodiment, prohibit breakpoints from being set within a protected range. In an embodiment, a protected range may be an atomic operation synchronization code range, either based on instructions generated by a compiler or based on source statements that are compiler directives. When a command, such as an add breakpoint command is received, the address of the breakpoint is compared to the protected range, and if the address is within the protected range, the breakpoint is not set. In another embodiment, if the address is within the protected range, the breakpoint is set before the start or after the end of the protected range. In this way, the problems of endless loops may be obviated.

Claims15

Dependent claims

A storage medium encoded with instructions, wherein the instructions when executed comprise:

determining whether an instruction to which a breakpoint is directed is within a protected range in a program, wherein the protected range is protected from the breakpoint being set;
prohibiting the breakpoint from being set within the protected range if the determining is true;
and
setting the breakpoint if the determining is false.
