Notes<\/strong><\/span><\/td>\n<\/tr>\n
<\/td>\nThanks to Herman D. Knoble and Arnaud Desitter for supplying some of the diagnostic tests.<\/td>\n<\/tr>\n
1<\/td>\n“Percentage Passes” is calculated from a total of 53 tests. No score is assigned for exception handling.<\/td>\n<\/tr>\n
2<\/td>\nExecution Time for TFFT.for, compiled using the diagnostic switches (see table above) – measured on the same machine as the benchmarks.<\/td>\n<\/tr>\n
3<\/td>\nCompiler issued warning message.<\/td>\n<\/tr>\n
4<\/td>\nCompiler issued fatal error message – no executable produced.<\/td>\n<\/tr>\n
5<\/td>\nRun-time message.<\/td>\n<\/tr>\n
6<\/td>\nArranged so that error is not visible at compile time.<\/td>\n<\/tr>\n
7<\/td>\nA variable is “uninitialized” if it has never been assigned a value. Data elements should be initialized before their value is used. The illegal use of an uninitialized variable can sometimes be detected at compile-time, but, because it may be data and flow dependent, usually requires run-time monitoring. In some cases, compilers implement this by checking for a special “uninitialized” bit pattern, such as 0x80, but this may result in false positives for one or two byte variables (and, rarely, in other cases). Use of a “shadow array” doubles memory requirements, but avoids false positives.<\/td>\n<\/tr>\n
8<\/td>\nCompilation order dependent. Compiler generates .mod file to allow interface checking.<\/td>\n<\/tr>\n
9<\/td>\nNon-specific error message, but full traceback.<\/td>\n<\/tr>\n
10<\/td>\nSpotted by Forcheck.<\/td>\n<\/tr>\n
11<\/td>\nThe test is passed if the program refuses the second open. For some reason, the Fortran standard does not allow a file to be opened twice, even for read-only access. It has been argued to me that allowing the second open is an extension to the standard, rather than a failure to spot an error.<\/td>\n<\/tr>\n
12<\/td>\nFalse positive detected<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n
