Chapter 2 Developing with LF Fortran Specify -nstchk to cause the compiler not to generate code for stack overflow checking. Though your program may execute faster, the stack is not protected from growing too large and corrupting data. -[N]SWM msgno Suppress Warning Message(s) Compile only. Default: -nswm To suppress a particular error message, specify its number after -swm. Example -swm 16,32 This example would suppress warning messages 16 and 32. To suppress all warnings, use -nw. { -TP | -TPP | -TP4 } Target Processor Compile only. Default: set on installation Specify -tp to generate code optimized for the Intel Pentium or Pentium MMX processors, or their generic counterparts. Specify -tpp to generate code optimized for the Intel Pentium Pro, Pentium II, Pentium III, or Celeron processors, or their generic counterparts. Specify -tp4 to generate code optimized for the Intel Pentium 4 processors. Please note: Code generated with -tp4 is not compatible with processors made previous to the Pentium 4. Code generated with -tpp is not compatible with processors made earlier than the Pentium Pro. -[N]TRACE Location and Call Traceback for Runtime Errors Compile and Link. Default: -trace The -trace option causes a call traceback with procedure names and line numbers to be generated with runtime error messages. 44 LF Fortran Express User’s Guide
-[N]TRAP [d][i][o][u] Trap NDP Exceptions Compile only. Default: -ntrap Compiler and Linker Options The -trap option specifies how each of four numeric data processor (NDP) exceptions will be handled at execution time of your program. Specify -trap with any combination of d, i, o, and u to instruct the NDP chip to generate an interrupt when it detects the specified exception(s) and generate an error message. At least one argument must be specified when the -trap option is used. Note that the zero divide exception for two and four byte integers is always handled by hardware, and is not affected by the trap option. Note that trapping cannot be disabled when -quad is specified, except by using the NDPEXC subroutine or the ERRSET service subroutine (see the file ReadMe_Service_Routines.txt). -[N]UNROLL [(limit)] Compile only. Default: -unroll Loop unrolling Specify -unroll (limit) to control the level of loop unrolling. limit is a number in the range 2 ≤ limit ≤ 100 enclosed with parenthesis, and denotes the maximum level of loop expansion. If limit is omitted, the value of limit is determined by the compiler. Note that -O0 causes -nunroll to be sent to the compiler by default, but this can be overridden by specifying -O0 -unroll. -[N]VARHEAP [(size)] Compile only. Default: -nvarheap Table 4: NDP Exceptions NDP Exception Option Argument Divide-by-Zero d Invalid Operation i Overflow o Underflow u Place local variables on heap Specify -varheap to cause local variables to be allocated on the heap rather than on the stack.
