obtained gcc-4.6.4.tar.bz2 from upstream website;upstream
verified gcc-4.6.4.tar.bz2.sig;
imported gcc-4.6.4 source tree from verified upstream tarball.
downloading a git-generated archive based on the 'upstream' tag
should provide you with a source tree that is binary identical
to the one extracted from the above tarball.
if you have obtained the source via the command 'git clone',
however, do note that line-endings of files in your working
directory might differ from line-endings of the respective
files in the upstream repository.

In the past, the C versions distributed + * by Rick Richardson (Version 1.1) and by Reinhold Weicker + * had small (though not significant) differences. + * + * 2) As far as it is possible without changes to the Dhrystone + * statistics, optimizing compilers should be prevented from + * removing significant statements. + * + * This C version has been developed in cooperation with + * Rick Richardson (Tinton Falls, NJ), it incorporates many + * ideas from the "Version 1.1" distributed previously by + * him over the UNIX network Usenet. + * I also thank Chaim Benedelac (National Semiconductor), + * David Ditzel (SUN), Earl Killian and John Mashey (MIPS), + * Alan Smith and Rafael Saavedra-Barrera (UC at Berkeley) + * for their help with comments on earlier versions of the + * benchmark. + * + * Changes: In the initialization part, this version follows mostly + * Rick Richardson's version distributed via Usenet, not the + * version distributed earlier via floppy disk by Reinhold Weicker. + * As a concession to older compilers, names have been made + * unique within the first 8 characters. + * Inside the measurement loop, this version follows the + * version previously distributed by Reinhold Weicker. + * + * At several places in the benchmark, code has been added, + * but within the measurement loop only in branches that + * are not executed. The intention is that optimizing compilers + * should be prevented from moving code out of the measurement + * loop, or from removing code altogether. Since the statements + * that are executed within the measurement loop have NOT been + * changed, the numbers defining the "Dhrystone distribution" + * (distribution of statements, operand types and locality) + * still hold. Except for sophisticated optimizing compilers, + * execution times for this version should be the same as + * for previous versions. + * + * Since it has proven difficult to subtract the time for the + * measurement loop overhead in a correct way, the loop check + * has been made a part of the benchmark. This does have + * an impact - though a very minor one - on the distribution + * statistics which have been updated for this version. + * + * All changes within the measurement loop are described + * and discussed in the companion paper "Rationale for + * Dhrystone version 2". + * + * Because of the self-imposed limitation that the order and + * distribution of the executed statements should not be + * changed, there are still cases where optimizing compilers + * may not generate code for some statements. To a certain + * degree, this is unavoidable for small synthetic benchmarks. + * Users of the benchmark are advised to check code listings + * whether code is generated for all statements of Dhrystone. + * + * Version 2.1 is identical to version 2.0 distributed via + * the UNIX network Usenet in March 1988 except that it corrects + * some minor deficiencies that were found by users of version 2.0. + * The only change within the measurement loop is that a + * non-executed "else" part was added to the "if" statement in + * Func_3, and a non-executed "else" part removed from Proc_3. + * + *************************************************************************** + * + * Defines: The following "Defines" are possible: + * -DREG=register (default: Not defined) + * As an approximation to what an average C programmer + * might do, the "register" storage class is applied + * (if enabled by -DREG=register) + * - for local variables, if they are used (dynamically) + * five or more times + * - for parameters if they are used (dynamically) + * six or more times + * Note that an optimal "register" strategy is + * compiler-dependent, and that "register" declarations + * do not necessarily lead to faster execution. + * -DNOSTRUCTASSIGN (default: Not defined) + * Define if the C compiler does not support + * assignment of structures. + * -DNOENUMS (default: Not defined) + * Define if the C compiler does not support + * enumeration types. + * -DTIMES (default) + * -DTIME + * The "times" function of UNIX (returning process times) + * or the "time" function (returning wallclock time) + * is used for measurement. + * For single user machines, "time ()" is adequate. For + * multi-user machines where you cannot get single-user + * access, use the "times ()" function. If you have + * neither, use a stopwatch in the dead of night. + * "printf"s are provided marking the points "Start Timer" + * and "Stop Timer". DO NOT use the UNIX "time(1)" + * command, as this will measure the total time to + * run this program, which will (erroneously) include + * the time to allocate storage (malloc) and to perform + * the initialization. + * -DHZ=nnn + * In Berkeley UNIX, the function "times" returns process + * time in 1/HZ seconds, with HZ = 60 for most systems. + * CHECK YOUR SYSTEM DESCRIPTION BEFORE YOU JUST APPLY + * A VALUE. + * + *************************************************************************** + * + * Compilation model and measurement (IMPORTANT): + * + * This C version of Dhrystone consists of three files: + * - dhry.h (this file, containing global definitions and comments) + * - dhry_1.c (containing the code corresponding to Ada package Pack_1) + * - dhry_2.c (containing the code corresponding to Ada package Pack_2) + * + * The following "ground rules" apply for measurements: + * - Separate compilation + * - No procedure merging + * - Otherwise, compiler optimizations are allowed but should be indicated + * - Default results are those without register declarations + * See the companion paper "Rationale for Dhrystone Version 2" for a more + * detailed discussion of these ground rules. + * + * For 16-Bit processors (e.g. 80186, 80286), times for all compilation + * models ("small", "medium", "large" etc.) should be given if possible, + * together with a definition of these models for the compiler system used. + * + ************************************************************************** + * + * Dhrystone (C version) statistics: + * + * [Comment from the first distribution, updated for version 2. + * Note that because of language differences, the numbers are slightly + * different from the Ada version.] + * + * The following program contains statements of a high level programming + * language (here: C) in a distribution considered representative: + * + * assignments 52 (51.0 %) + * control statements 33 (32.4 %) + * procedure, function calls 17 (16.7 %) + * + * 103 statements are dynamically executed.
