CPU2006 Flag Description
Phytium D2000 @ 2.3GHz

This macro specifies that the target system uses the LP64 data model; specifically, that integers are 32 bits, while longs and pointers are 64 bits.

This macro indicates that the benchmark is being compiled on an AMD64-compatible system running the Linux operating system.

Tells the compiler to conform to a specific language standard.

If optimization level is >= 2 in gcc-4.1, strict-aliasing is used, and this could cause probelms when a pointer is referencing to a different type of object and the object is refered thereafter by using this pointer. That is the case in this example. So you should force the compiler to not use strict-aliasing by a argument "-fno-strict-aliasing" if you want to use "-O2" or "-O3".

This option is used to indicate that the host system's integers are 32-bits wide, and longs and pointers are 64-bits wide. Not all benchmarks recognize this macro, but the preferred practice for data model selection applies the flags to all benchmarks; this flag description is a placeholder for those benchmarks that do not recognize this macro.

This flag can be set for SPEC compilation for Linux using default compiler.

Process FILE as if `#include "file"' appeared as the first line of the primary source file. However, the first directory searched for FILE is the preprocessor's working directory _instead of_ the directory containing the main source file. If not found there, it is searched for in the remainder of the `#include "..."' search chain as normal. If multiple `-include' options are given, the files are included in the order they appear on the command line.
