* 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:
*
* 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:
* 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.
- *
- * _SOFT_HOSTID
- * This indicates that the implementation obtains the hostid
- * from the file /etc/hostid, rather than from hardware.
