Several different versions of the bootstrap compiler can coexist--each being responsible for targeting another CPU-OS combination. Structure CMB is the default bootstrap compiler that targets the current system; it is exported from $smlnj/cmb.cm. The following table lists the names of other structures--those corresponding to various cross-compilers. All these structures share the same signature.
The table also shows the names of libraries that the structures are exported from as well as those arch and os strings that are used to name binfile- and stablefile-directory.
| library | structure | architecture | OS | arch | os |
|
$smlnj/cmb.cm $smlnj/cmb/current.cm |
CMB | current | current | ||
| $smlnj/cmb/alpha32-unix.cm | Alpha32UnixCMB | Alpha | Unix | alpha32 | unix |
| $smlnj/cmb/hppa-unix.cm | HPPAUnixCMB | HP-PA | Unix | hppa | unix |
| $smlnj/cmb/ppc-macos.cm | PPCMacOSCMB | Power-PC | Mac-OS | ppc | macos |
| $smlnj/cmb/ppc-unix.cm | PPCUnixCMB | Power-PC | Unix | ppc | unix |
| $smlnj/cmb/sparc-unix.cm | SparcUnixCMB | Sparc | Unix | sparc | unix |
| $smlnj/cmb/x86-unix.cm | X86UnixCMB | Intel x86 | Unix | x86 | unix |
| $smlnj/cmb/x86-win32.cm | X86Win32CMB | Intel x86 | Win32 | x86 | win32 |
| $smlnj/cmb/all.cm | all of the above (except CMB) |
As an example, consider targeting a Sparc/Unix system. The first step is to load the library that exports the corresponding cross-compiler:
CM.autoload "$smlnj/cmb/sparc-unix.cm";
Once this is done, run the equivalent of CMB.make:
SparcUnixCMB.make ();
This will recompile the compiler, producing object code for a Sparc. Binfiles will be stored under sml.bin.sparc-unix and stable libraries under sml.boot.sparc-unix.
