It responds to problems that have arisen in the nearly 4 years since the previous release, improves compatibility, and improves stability. Changes include: * Updates to 9 benchmarks, primarily due to portability issues on new platforms * Additional toolsets to support newer platforms * Refreshes for the sources of the tools, and fixes for the buildtools procedures, to make it easier to build tools in the future if and where needed ---------------------------------------------------------------------- New systems supported With this release of SPEC CPU2000, new support is added for: * MacOS X on Intel hardware * GLIBC 2.2+-based 64-bit x86-64 systems * RedHat AS3+ and SuSE 9+ Linux on Itanium-based systems Systems no longer supported With this release of SPEC CPU2000, support is removed for: * Reliant UNIX on MIPS-based systems * Linux on SPARC-based systems * Linux on Alpha-based systems * Windows on Alpha-based systems ----------------------------------------------------------- Note: links to SPEC CPU2000 documents on this web page assume that you are reading the page from a directory that also contains the other SPEC CPU2000 documents. If by some chance you are reading this web page from a location where the links do not work, try accessing the referenced documents at one of the following locations: * www.spec.org/cpu2000/docs/ * The $SPEC/docs/ directory on a Unix system where SPEC CPU2000 has been installed. * The %spec%\docs\ directory on a Windows system where SPEC CPU2000 has been installed. * The docs/ or docs\ directory on your SPEC CPU2000 distribution CD-ROM. ----------------------------------------------------------- Documentation Updates All of the documents with ".txt" extensions now have CRLF line-endings for the convenience of Windows users. Other documentation updates include: * tools_build (and tools_build.txt), which have been updated to reflect changes due to the tools source update. * install_guide_unix.html which has been updated to reflect a small change in the installation scripts * Revisions, which contains a detailed list of all changes made to v1.3. Tools source updates The tools sources have been updated to make building the tools on new systems easier. The build system has also been updated to catch errors during the tools build process that would have previously gone unreported. Tools updates The monitor_wrapper facility has been modified to not execute during training runs for builds using feedback-directed optimization. Changes to benchmarks The following benchmark changes were made in V1.3: * 176.gcc: A potentially problematic uninitialized variable error has been fixed. Additionally, several problems relating to building 176.gcc with newer versions of GCC have been fixed: * The value for OBSTACK_INTERFACE_VERSION has been changed to -1 in order to allow 176.gcc to build on 64-bit systems with GCC. * Uses of the cast as lvalue extension have been removed in order to allow compilation using GCC 3.5.0 and later. * A prototype for exact_log2_wide was added to correct a type mismatch which was causing sign-extension problems on 64-bit MacOS X systems. * A workaround for a bug in varargs support in the Windows 64 PSDK for x86-64 was added. * Added portability defines for 64-bit Solaris/x64 (SOLARIS_X64) and other systems which need to have alloca.h included (SPEC_CPU2000_NEED_ALLOCA_H). * 186.crafty: * Eliminated common global symbols; this allows GCC to build it even in the presence of the -fno-common switch. * Added portability defines for Solaris/x86 (SOLARIS_X86) and Solaris/x64 (SOLARIS_X64) * 187.facerec: In fft2d.f90, don't check the shape of FTemp until after we first ensure that it exists. * 188.ammp: Added a function prototype and added an explicit return type to a function declaration to quiet a couple of warnings. * 191.fma3d: Changed the name of one output file so that it can be automatically deleted. This works around a race condition seen on Windows which could cause multi-copy rate runs to fail. * 252.eon: Several changes were made to enhance standards compliance: * The cerrno header file is now included unless SPEC_CPU2000_NO_ERRNO_MACRO is defined. This is necessary for environments which do not export errno by default. * The local version of fmax() has been renamed to avoid conflict with library functions of the same name. * Wrappers for iostream.h and fstream.h have been provided for systems that no longer support "legacy" headers in C++. * 253.perlbmk: * Added defines for MacOS X on PowerPC and Intel-based systems. * SPEC_CPU2000_GLIBC22 settings are now the default on Linux. They can be turned off by definining SPEC_CPU2000_NO_HAS_FGETPOS and SPEC_CPU2000_NO_HAS_FSETPOS. * Some platform-specific sources are usually selected automatically; Windows users wishing to get the non-Windows sources can set the environment variable SPEC_NOT_REALLY_WINDOWS to achieve this end. * 255.vortex: Added code to set two closed file pointers to NULL in order to avoid attempting to use them for output. Also fixed a comment bug which claimed that a long on P64 systems was 8 bytes. * 300.twolf: * Some calls to free() were being passed two parameters; this has been fixed. * Eliminated common global symbols; this allows GCC to build it even in the presence of the -fno-common switch. Configuration Files Updated All of the configuration files were updated.
