-xpagesize=n
(SPARC) Set the preferred page size for the stack and
the heap.
The n value must be one of the following:
8K 64K 512K 4M 32M 256M 2G 16G or default.
You must specify a valid page size for the Solaris
operating environment on the target platform, as
returned by getpagesize(3C). If you do not specify a
valid pagesize, the request is silently ignored at
run-time. The Solaris environment 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.
The -xpagesize option has no effect unless you use it
at compile time and at link time.
Note that this feature is not available on Solaris 7
and 8. A program compiled with this option will not
link on Solaris 7 and 8.
If you specify -xpagesize=default, the Solaris environ-
ment sets the page size. -xpagesize without an argument
is the equivalent to -xpagesize=default.
Compiling with this option has the same effect as set-
ting the LD_PRELOAD environment variable to mpss.so.1
with the equivalent options, or running the Solaris 9
command ppgsz(1) with the equivalent options before
running the program. See the Solaris 9 man pages for details.
This option is a macro for -xpagesize_heap and
-xpagesize_stack. These two options accept the same
arguments as -xpagesize: 8K, 64K, 512K, 4M, 32M, 256M,
2G, 16G, default. You can set them both with the same
value by specifying -xpagesize=n or you can specify
them individually with different values.
-xpagesize_heap=n
(SPARC) Set the page size in memory for the heap. n can
be 8K, 64K, 512K, 4M, 32M, 256M, 2G, 16G, or default.
You must specify a valid page size for the Solaris
operating environment on the target platform, as
returned by getpagesize(3C). If you do not specify a
valid page size, the request is silently ignored at run-time.
You can use pmap(1) or meminfo(2) to determine page
size at the target platform.
If you specify -xpagesize_heap=default, the Solaris
environment sets the page size. -xpagesize_heap without
an argument is the equivalent to
-xpagesize_heap=default.
Compiling with this option has the same effect as set-
ting the LD_PRELOAD environment variable to mpss.so.1
with the equivalent options, or running the Solaris 9
command ppgsz(1) with the equivalent options before
running the program. See the Solaris 9 man pages for
details.
Note that this feature is not available on Solaris 7
and 8. A program compiled with this option will not
link on Solaris 7 and 8.
-xpagesize_stack=n
(SPARC) Set the page size in memory for the stack. n
can be 8K, 64K, 512K, 4M, 32M, 256M, 2G, 16G, default.
You must specify a valid page size for the Solaris
operating environment on the target platform, as
returned by getpagesize(3C). If you do not specify a
valid page size, the request is silently ignored at
run-time.
You can use pmap(1) or meminfo(2) to determine page
size at the target platform.
If you specify -xpagesize_stack=default, the Solaris
environment sets the page size. -xpagesize_stack
without an argument is the equivalent to
-xpagesize_stack=default.
Compiling with this option has the same effect as set-
ting the LD_PRELOAD environment variable to mpss.so.1
with the equivalent options, or running the Solaris 9
command ppgsz(1) with the equivalent options before
running the program. See the Solaris 9 man pages for
details.
Note that this feature is not available on Solaris 7
and 8. A program compiled with this option will not
link on Solaris 7 and 8.
