A.2.159.1 Values

The following values are valid for SPARC: 4k, 8K, 64K, 512K, 2M, 4M, 32M, 256M, 2G, 16G, or default.

The following values are valid on x86/x64: 4K, 2M. 4M, 1G, or default.

You must specify a valid page size for the target platform. If you do not specify a valid pagesize, the request is silently ignored at run-time.

Use the getpagesize(3C) command on the Solaris operating system to determine the number of bytes in a page. The Solaris operating system offers no guarantee that the page size request will be honored. You can use pmap(1) or meminfo(2) to determine page size of the target platform.

Defaults

If you specify -xpagesize=default, the Solaris operating system sets the page size.

Expansions

This option is a macro for -xpagesize_heap and -xpagesize_stack. These two options accept the same arguments as -xpagesize: 4k, 8K, 64K, 512K, 2M, 4M, 32M, 256M, 2G, 16G, or default. You can set them both with the same value by specifying -xpagesize or you can specify them individually with different values.

Warnings

The -xpagesize option has no effect unless you use it at compile time and at link time. See 3.3.3 Compile-Time and Link-Time Options for a complete list of options that must be specified at both compile time and link time.

See Also

Compiling with this option has the same effect as setting the LD_PRELOAD environment variable to mpss.so.1 with the equivalent options, or running the Solaris command ppgsz(1) with the equivalent options before running the program. See the Solaris man pages for details.
