<P>PROBLEM TO BE SOLVED: To provide a debugger having high coverage measurement accuracy. <P>SOLUTION: A debugger of the present invention includes: a symbol-address conversion table reading unit; an address-line number conversion table reading unit; a branch instruction first retrieval unit for determining a retrieval address range for a branch instruction on the basis of the symbol-address conversion table; a branch instruction second retrieval unit for determining a retrieval address for the branch instruction on the basis of the address-line number conversion table reading unit; a trap instruction embedding unit for replacing the branch instruction with a trap instruction and managing the branch instruction, which is replaced in a trap management table; a passage state determination unit for determining whether or not the branch instruction managed in the trap management table is passed; and a coverage state editing unit for performing coverage measurement on the basis of the trap management table and the symbol-address conversion table. <P>COPYRIGHT: (C)2012,JPO&INPIT |
