# ToggleTraceBasicBlocks ## Description Toggle basic block tracing. This command starts basic block tracing. You can then use all debugger commands as usual: the debugger will save all addresses where a temporary basic block breakpoint was reached. Internally, the debugger runs the current thread normally, setting temporary breakpoints in the last instruction of every basic block of every function referenced from the current function and also at any call instruction in the middle of the traced basic blocks. Basic block tracing is slower than normal execution but faster than instruction or function tracing. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
