 397 #### Unified HP-UX ANSI C configs.
 398 # Special notes:
 399 # - Originally we were optimizing at +O4 level. It should be noted
 400 #   that the only difference between +O3 and +O4 is global inter-
 401 #   procedural analysis. As it has to be performed during the link
 402 #   stage the compiler leaves behind certain pseudo-code in lib*.a
 403 #   which might be release or even patch level specific. Generating
 404 #   the machine code for and analyzing the *whole* program appears
 405 #   to be *extremely* memory demanding while the performance gain is
 406 #   actually questionable. The situation is intensified by the default
 407 #   HP-UX data set size limit (infamous 'maxdsiz' tunable) of 64MB
 408 #   which is way too low for +O4. In other words, doesn't +O3 make
 409 #   more sense?
 410 # - Keep in mind that the HP compiler by default generates code
 411 #   suitable for execution on the host you're currently compiling at.
 412 #   If the toolkit is meant to be used on various PA-RISC processors
 413 #   consider './Configure hpux-parisc-[g]cc +DAportable'.
 414 # - -DMD32_XARRAY triggers workaround for compiler bug we ran into in
 415 #   32-bit message digests. (For the moment of this writing) HP C
 416 #   doesn't seem to "digest" too many local variables (they make "him"
 417 #   chew forever:-). For more details look-up MD32_XARRAY comment in
 418 #   crypto/sha/sha_lcl.h.
 419 # - originally there were 32-bit hpux-parisc2-* targets. They were
 420 #   scrapped, because a) they were not interchangeable with other 32-bit
 421 #   targets; b) performance-critical 32-bit assembly modules implement
 422 #   even PA-RISC 2.0-specific code paths, which are chosen at run-time,
 423 #   thus adequate performance is provided even with PA-RISC 1.1 build.

 678         # As for c) option. It actually makes no sense to specify
 679         # maximum to be less than ARMv7, because it's the least
 680         # requirement for run-time switch between platform-specific
 681         # code paths. And without run-time switch performance would be

 686         # picks instructions in little-endian order. Another similar
 687         # limitation is that -mthumb can't "cross" -march=armv6t2
