It's job is to test the executable that 5 # was generated by mixing/matching good & bad object files, and determine 6 # whether the resulting binary is good or bad. 7 # 8 # In this particular case, the generated binary is 'bin-trees'. This 9 # script runs the binary, captures its output, and compares the output 10 # to a file containg the correct (good) output, and three files containing 11 # what the bad output might look like, depending on if one of the two 12 # possile bad .o files was used, or if both bad .o files were used. 13 # 14 # If the output matches the known good output, this returns 0. 15 # If the output matches any known bad output, this returns 1. 16 # If the output does not match the good or bad outputs, this returns 125. 17 # 18 19 source full_bisect_test/common.sh 20 21 full_bisect_test/bin-trees > full_bisect_test/temp_output.txt 22 23 diff full_bisect_test/temp_output.txt full_bisect_test/good-output.txt &> /dev/null 24 retval=$? 25 26 if [[ ${retval} -eq 0 ]]; then 27 rm -f full_bisect_test/temp_output.txt 28 exit 0 29 fi 30 31 diff full_bisect_test/temp_output.txt full_bisect_test/bad-output-1.txt &> /dev/null 32 retval=$? 33 34 if [[ ${retval} -eq 0 ]]; then 35 rm -f full_bisect_test/temp_output.txt 36 exit 1 37 else 38 diff full_bisect_test/temp_output.txt full_bisect_test/bad-output-2.txt &> /dev/null 39 retval=$? 40 if [[ ${retval} -eq 0 ]]; then 41 rm -f full_bisect_test/temp_output.txt 42 exit 1 43 else 44 diff full_bisect_test/temp_output.txt full_bisect_test/bad-output-3.txt &> /dev/null 45 retval=$? 46 if [[ ${retval} -eq 0 ]]; then 47 rm -f full_bisect_test/temp_output.txt 48 exit 1 49 fi 50 fi 51 fi 52 53 rm -f full_bisect_test/temp_output.txt 54 exit 125 55 56 57
