264 /*
265 Note, that there are really 3 APIs:
266
267 mips, mipsel:
268 O32 ABI, ILP32, "long long" in a "aligned" even-odd register
269 pair, 4 argument registers
270
271 mipsn32, mipsn32el
272 N32 ABI, ILP32, but with 64 bit wide registers, and "long long"
273 in a single register, 8 argument registers
274
275 mips64, mips64el
276 N64 ABI, LP64, 8 argument registers
277
278 where O32, N32, and N64 are the ABI names. ILP32 means that
279 (I)int, (L)long, (P)pointer are 32bit long. LP64 means that
280 long and pointer are 64bit long. "el" denotes if the ABI is
281 little endian.
282
283 N32 is different from 032, in the calling convention. Arguments
284 passed as 64bit (long long) reference, and there are 8 of those.
285 O32 is the one closest to "normal" GNU/Linux on i386.
286
287 It's a bit more complex. MIPS spans probably the largest
288 performance range of any CPU family, from a 32bit 20 MHz
289 Microcontroller (made by Microchip) up to a 64bit monster with
290 over 5000 CPUs (made by SiCortex). Obviously, only the 64bit
291 CPUs can run 64bit code, but 32bit code runs on all of them.
292
293 The use cases for the different ABIs are:
294 - O32: Most compatible, runs everywhere
295 - N32: Best performance on 64 bit if a large address space isn't
296 needed. It is faster than O32 due to improved calling
297 conventions, and it is faster than N64 due to reduced
298 pointer size.
299 - N64: Huge address space.
300
301 Currently (end 2007) Debian GNU/Linux only supports O32
