/* Attributes of the selected architecture:
|
|
|
|
The following four macros define specific aspects of the system. They
|
|
are defined as strings, or specifically undefined:
|
|
|
|
IMPLEMENTATION_MACHINE machine type
|
|
IMPLEMENTATION_CPU cpu type
|
|
IMPLEMENTATION_OS operating system
|
|
IMPLEMENTATION_FS file system
|
|
|
|
Big endian vs. little endian:
|
|
|
|
BIGENDIAN defined to 1 to denote bigendian systems
|
|
|
|
C compiler:
|
|
|
|
OLD_FASHIONED_C defined to 1 for pre-ANSI compilers
|
|
|
|
Alignment:
|
|
|
|
DOUBLE_ALIGN defined to 1 to force doubles to be aligned on
|
|
an even S2CINT boundary
|
|
|
|
Macro expansion:
|
|
|
|
NEED_MACRO_ARGS defined to 1 to declare a macro like X() as
|
|
X(dummy)
|
|
|
|
The types S2CINT and S2CUINT are defined to be signed and unsigned integers
|
|
that are the same size as pointers. This is the basic "word" used by
|
|
Scheme->C.
|
|
|
|
The machine state when a continuation is created is captured in the
|
|
sc_jmp_buf data structure.
|
|
|
|
STACKPTR( x ) is a define that stores the address of the stack pointer
|
|
in x.
|
|
|
|
Unix flavors:
|
|
|
|
POSIX POSIX.1 compliant
|
|
SYSV System V or derivative
|
|
SYSV4 System V release 4 (also define SYSV, POSIX)
