A.2.106 -xaddr32

(Solaris x86/x64 only) The -xaddr32=yes compilation flag restricts the resulting executable or shared object to a 32-bit address space.

An executable that is compiled in this manner results in the creation of a process that is restricted to a 32-bit address space.

When -xaddr32=no is specified a usual 64 bit binary is produced.

If the -xaddr32 option is not specified, -xaddr32=no is assumed.

If only -xaddr32 is specified -xaddr32=yes is assumed.

This option is only applicable to -m64 compilations and only on Solaris platforms supporting SF1_SUNW_ADDR32 software capability. Since Linux kernels do not support address space limitation, this option is not available on Linux.

When linking, if a single object file was compiled with -xaddr32=yes the whole output file is assumed to be compiled with -xaddr32=yes.

A shared object that is restricted to a 32-bit address space must be loaded by a process that executes within a restricted 32-bit mode address space.

For more information refer to the SF1_SUNW_ADDR32 software capabilities definition, described in the Linker and Libraries Guide.
