0 | 38 //** The DebugInformationRecorder collects debugging information |
39 // for a compiled method. | |
40 // Debugging information is used for: | |
41 // - garbage collecting compiled frames | |
42 // - stack tracing across compiled frames | |
43 // - deoptimizating compiled frames | |
44 // | |
45 // The implementation requires the compiler to use the recorder | |
46 // in the following order: | |
47 // 1) Describe debug information for safepoints at increasing addresses. | |
48 // a) Add safepoint entry (use add_safepoint or add_non_safepoint) | |
49 // b) Describe scopes for that safepoint | |
50 // - create locals if needed (use create_scope_values) | |
51 // - create expressions if needed (use create_scope_values) | |
52 // - create monitor stack if needed (use create_monitor_values) | |
53 // - describe scope (use describe_scope) | |
54 // "repeat last four steps for all scopes" | |
55 // "outer most scope first and inner most scope last" | |
56 // NB: nodes from create_scope_values and create_locations | |
57 // can be reused for simple sharing. | |
58 // - mark the end of the scopes (end_safepoint or end_non_safepoint) | |
