Method, apparatus and article for generation of debugging information

摘要

Call frame information is used by debugging software. It records how to restore the parent stack frame at any point during execution of a program. It is normally generated during compilation and stored in the executable in a compressed format, consisting of sequences of instructions that describe how the current call frame changes during execution of each function. Described herein is a means of generating call frame information at link time, using linker macro calls generated by a small set of assembler macros.
