Arithmetic tests needs to be updated for advanced compiler optimization

Hi,
I was trying to build Linux Benchmarks with latest Intel C++ Compiler.
When I used -ipo (inter-procedural optimization) option, arithmetic test (arith.c) failed on execution.

The problem is Intel compiler's advanced optimization option (-ipo) optimizes much more than expected and this results in elimination of some part of code.
/-------------------------------------------------
++iter;
/* the loop calls a function to insure that something is done
the results of the function are fed back in (just so they
they won't be thrown away. A loop with
unused assignments may get optimized out of existence */
result = dumb_stuff(result);
/--------------------------------------------------------

This part gets eliminated becuase of IPO.

Steps to reproduce:
$icc -o ./pgms/arithoh -DTIME -O3 -xW -ipo -static -unroll -Darithoh ./src/arith.c

$./pgms/arithoh 1
0 loops

and this results in divide by zero error.

Regards,
CP

NAME
iasl -- Intel ACPI compiler/decompiler SYNOPSIS
iasl [-2cefghl] [-b type] [-d file] [-dc file] [-hc] [-hr] [-i type] [-ln] [-ls] [-oa] [-of] [-oi] [-on] [-ot] [-p prefix] [-s type] [-t type] [-vi] [-vo] [-vr] [-vs] [-x level] [-w level] input-file DESCRIPTION
The iasl utility is a compiler/decompiler for ACPI Source Language (ASL) and ACPI Machine Language (AML). Major features of iasl include: o Full support for the ACPI 3.0b Specification including ASL grammar elements and operators. o Extensive compiler syntax and semantic error checking, especially in the area of control methods. This reduces the number of errors that are not discovered until the AML code is actually interpreted (i.e., the compile-time error checking reduces the number of run-time errors). o Multiple types of output files, including formatted listing files with intermixed source, several types of AML files, and error messages. OPTIONS
-2 Emit ACPI 2.0 compatible ASL code. -b p|t|b Create compiler debug/trace file (*.txt). Types: Parse/Tree/Both. -c Parse only, no output generation. -d file Disassemble AML to ASL source code file (*.dsl). -dc file Disassemble AML and immediately compile it. (Obtain DSDT from current system if no input file.) -e Generate External() statements for unresolved symbols. -f Ignore errors, force creation of AML output file(s). -g Get ACPI tables and write to files (*.dat). -h Additional help and compiler debug options. -hc Display operators allowed in constant expressions. -hr Display ACPI reserved method names. -i a|c Create assembler or C include file (*.inc or *.h). -l Create mixed listing file (ASL source and AML) (*.lst). -ln Create namespace file (*.nsp). -ls Create combined source file (expanded includes) (*.src). -oa Disable all optimizations (compatibility mode). -of Disable constant folding. -oi Disable integer optimization to Zero/One/Ones. -on Disable named reference string optimization. -ot Display compile times. -p prefix Specify filename prefix for all output files (including .aml). -s a|c Create AML in assembler or C source file (*.asm or *.c). -t a|c Create AML in assembler or C hex table (*.hex). -vi Less verbose errors and warnings for use with IDEs. -vo Enable optimization comments. -vr Disable remarks. -vs Disable signon. -x level Set debug level for trace output. -w level Set warning level.
