/*
|
|
||||||
* This header file serves to group a set of well known defines and to
|
|
||||||
* set these for each instruction set architecture. These defines may
|
|
||||||
* be divided into two groups; characteristics of the processor and
|
|
||||||
* implementation choices for Solaris on a processor.
|
|
||||||
*
|
|
||||||
* Processor Characteristics:
|
|
||||||
*
|
|
||||||
* _LITTLE_ENDIAN / _BIG_ENDIAN:
|
|
||||||
* The natural byte order of the processor. A pointer to an int points
|
|
||||||
* to the least/most significant byte of that int.
|
|
||||||
*
|
|
||||||
* _STACK_GROWS_UPWARD / _STACK_GROWS_DOWNWARD:
|
|
||||||
* The processor specific direction of stack growth. A push onto the
|
|
||||||
* stack increases/decreases the stack pointer, so it stores data at
|
|
||||||
* successively higher/lower addresses. (Stackless machines ignored
|
|
||||||
* without regrets).
|
|
||||||
*
|
|
||||||
* _LONG_LONG_HTOL / _LONG_LONG_LTOH:
|
|
||||||
* A pointer to a long long points to the most/least significant long
|
|
||||||
* within that long long.
|
|
||||||
*
|
|
||||||
* _BIT_FIELDS_HTOL / _BIT_FIELDS_LTOH:
|
|
||||||
* The C compiler assigns bit fields from the high/low to the low/high end
|
|
||||||
* of an int (most to least significant vs. least to most significant).
|
|
||||||
*
|
|
||||||
* _IEEE_754:
|
|
||||||
* The processor (or supported implementations of the processor)
|
|
||||||
* supports the ieee-754 floating point standard. No other floating
|
|
||||||
* point standards are supported (or significant). Any other supported
|
|
||||||
* floating point formats are expected to be cased on the ISA processor
|
|
||||||
* symbol.
|
|
||||||
*
|
|
||||||
* _CHAR_IS_UNSIGNED / _CHAR_IS_SIGNED:
|
|
||||||
* The C Compiler implements objects of type `char' as `unsigned' or
|
|
||||||
* `signed' respectively. This is really an implementation choice of
|
|
||||||
* the compiler writer, but it is specified in the ABI and tends to
|
|
||||||
* be uniform across compilers for an instruction set architecture.
|
|
||||||
* Hence, it has the properties of a processor characteristic.
|
|
||||||
*
|
|
||||||
* _CHAR_ALIGNMENT / _SHORT_ALIGNMENT / _INT_ALIGNMENT / _LONG_ALIGNMENT /
|
|
||||||
* _LONG_LONG_ALIGNMENT / _DOUBLE_ALIGNMENT / _LONG_DOUBLE_ALIGNMENT /
|
|
||||||
* _POINTER_ALIGNMENT / _FLOAT_ALIGNMENT:
|
|
||||||
* The ABI defines alignment requirements of each of the primitive
|
|
||||||
* object types. Some, if not all, may be hardware requirements as
|
|
||||||
* well. The values are expressed in "byte-alignment" units.
|
|
||||||
*
|
|
||||||
* _MAX_ALIGNMENT:
|
|
||||||
* The most stringent alignment requirement as specified by the ABI.
|
|
||||||
* Equal to the maximum of all the above _XXX_ALIGNMENT values.
|
|
||||||
*
|
|
||||||
* _ALIGNMENT_REQUIRED:
|
|
||||||
* True or false (1 or 0) whether or not the hardware requires the ABI
|
|
||||||
* alignment.
|
|
||||||
*
|
|
||||||
* _LONG_LONG_ALIGNMENT_32
|
|
||||||
* The 32-bit ABI supported by a 64-bit kernel may have different
|
|
||||||
* alignment requirements for primitive object types. The value of this
|
|
||||||
* identifier is expressed in "byte-alignment" units.
|
|
||||||
*
|
|
||||||
* _HAVE_CPUID_INSN
|
|
||||||
* This indicates that the architecture supports the 'cpuid'
|
|
||||||
* instruction as defined by Intel. (Intel allows other vendors
|
|
||||||
* to extend the instruction for their own purposes.)
|
|
||||||
*
|
|
||||||
*
|
|
||||||
* Implementation Choices:
|
|
||||||
*
|
|
||||||
* _ILP32 / _LP64:
|
|
||||||
* This specifies the compiler data type implementation as specified in
|
|
||||||
* the relevant ABI. The choice between these is strongly influenced
|
|
||||||
* by the underlying hardware, but is not absolutely tied to it.
|
|
||||||
* Currently only two data type models are supported:
|
|
||||||
*
|
|
||||||
* _ILP32:
|
|
||||||
* Int/Long/Pointer are 32 bits. This is the historical UNIX
|
|
||||||
* and Solaris implementation. Due to its historical standing,
|
|
||||||
* this is the default case.
|
|
||||||
*
|
|
||||||
* _LP64:
|
|
||||||
* Long/Pointer are 64 bits, Int is 32 bits. This is the chosen
|
|
||||||
* implementation for 64-bit ABIs such as SPARC V9.
|
|
||||||
*
|
|
||||||
* _I32LPx:
|
|
||||||
* A compilation environment where 'int' is 32-bit, and
|
|
||||||
* longs and pointers are simply the same size.
|
|
||||||
*
|
|
||||||
* In all cases, Char is 8 bits and Short is 16 bits.
|
|
||||||
*
|
|
||||||
* _SUNOS_VTOC_8 / _SUNOS_VTOC_16 / _SVR4_VTOC_16:
|
|
||||||
* This specifies the form of the disk VTOC (or label):
|
|
||||||
*
|
|
||||||
* _SUNOS_VTOC_8:
|
|
||||||
* This is a VTOC form which is upwardly compatible with the
|
|
||||||
* SunOS 4.x disk label and allows 8 partitions per disk.
|
|
||||||
*
|
|
||||||
* _SUNOS_VTOC_16:
|
|
||||||
* In this format the incore vtoc image matches the ondisk
|
|
||||||
* version. It allows 16 slices per disk, and is not
|
|
||||||
* compatible with the SunOS 4.x disk label.
|
|
||||||
*
|
|
||||||
* Note that these are not the only two VTOC forms possible and
|
|
||||||
* additional forms may be added. One possible form would be the
|
|
||||||
* SVr4 VTOC form. The symbol for that is reserved now, although
|
|
||||||
* it is not implemented.
|
|
||||||
*
|
|
||||||
* _SVR4_VTOC_16:
|
|
||||||
* This VTOC form is compatible with the System V Release 4
|
|
||||||
* VTOC (as implemented on the SVr4 Intel and 3b ports) with
|
|
||||||
* 16 partitions per disk.
|
|
||||||
*
|
|
||||||
*
|
|
||||||
* _DMA_USES_PHYSADDR / _DMA_USES_VIRTADDR
|
|
||||||
* This describes the type of addresses used by system DMA:
|
|
||||||
*
|
|
||||||
* _DMA_USES_PHYSADDR:
|
|
||||||
* This type of DMA, used in the x86 implementation,
|
|
||||||
* requires physical addresses for DMA buffers. The 24-bit
|
|
||||||
* addresses used by some legacy boards is the source of the
|
|
||||||
* "low-memory" (<16MB) requirement for some devices using DMA.
|
|
||||||
*
|
|
||||||
* _DMA_USES_VIRTADDR:
|
|
||||||
* This method of DMA allows the use of virtual addresses for
|
|
||||||
* DMA transfers.
|
|
||||||
*
|
|
||||||
* _FIRMWARE_NEEDS_FDISK / _NO_FDISK_PRESENT
|
|
||||||
* This indicates the presence/absence of an fdisk table.
|
|
||||||
*
|
|
||||||
* _FIRMWARE_NEEDS_FDISK
|
|
||||||
* The fdisk table is required by system firmware. If present,
|
|
||||||
* it allows a disk to be subdivided into multiple fdisk
|
|
||||||
* partitions, each of which is equivalent to a separate,
|
|
||||||
* virtual disk. This enables the co-existence of multiple
|
|
||||||
* operating systems on a shared hard disk.
|
|
||||||
*
|
|
||||||
* _NO_FDISK_PRESENT
|
|
||||||
* If the fdisk table is absent, it is assumed that the entire
|
|
||||||
* media is allocated for a single operating system.
|
|
||||||
*
|
|
||||||
* _HAVE_TEM_FIRMWARE
|
|
||||||
* Defined if this architecture has the (fallback) option of
|
|
||||||
* using prom_* calls for doing I/O if a suitable kernel driver
|
|
||||||
* is not available to do it.
|
|
||||||
*
|
|
||||||
* _DONT_USE_1275_GENERIC_NAMES
|
|
||||||
* Controls whether or not device tree node names should
|
|
||||||
* comply with the IEEE 1275 "Generic Names" Recommended
|
|
||||||
* Practice. With _DONT_USE_GENERIC_NAMES, device-specific
|
|
||||||
* names identifying the particular device will be used.
|
|
||||||
*
|
|
||||||
* __i386_COMPAT
|
|
||||||
* This indicates whether the i386 ABI is supported as a *non-native*
|
|
||||||
* mode for the platform. When this symbol is defined:
|
|
||||||
* - 32-bit xstat-style system calls are enabled
|
|
||||||
* - 32-bit xmknod-style system calls are enabled
|
|
||||||
* - 32-bit system calls use i386 sizes -and- alignments
|
|
||||||
*
|
|
||||||
* Note that this is NOT defined for the i386 native environment!
|
|
||||||
*
|
|
||||||
* __x86
|
|
||||||
* This is ONLY a synonym for defined(__i386) || defined(__amd64)
|
|
||||||
* which is useful only insofar as these two architectures share
|
|
||||||
* common attributes. Analogous to __sparc.
|
|
||||||
*
|
|
||||||
* _PSM_MODULES
|
|
||||||
* This indicates whether or not the implementation uses PSM
|
|
||||||
* modules for processor support, reading /etc/mach from inside
|
|
||||||
* the kernel to extract a list.
|
|
||||||
*
|
|
||||||
* _RTC_CONFIG
|
|
||||||
* This indicates whether or not the implementation uses /etc/rtc_config
|
|
||||||
* to configure the real-time clock in the kernel.
|
|
||||||
*
|
|
||||||
* _UNIX_KRTLD
|
|
||||||
* This indicates that the implementation uses a dynamically
|
|
||||||
* linked unix + krtld to form the core kernel image at boot
|
|
||||||
* time, or (in the absence of this symbol) a prelinked kernel image.
|
|
||||||
*
|
|
||||||
* _OBP
|
|
||||||
* This indicates the firmware interface is OBP.
