 442 # Special notes:
 443 # - Originally we were optimizing at +O4 level. It should be noted
 444 #   that the only difference between +O3 and +O4 is global inter-
 445 #   procedural analysis. As it has to be performed during the link
 446 #   stage the compiler leaves behind certain pseudo-code in lib*.a
 447 #   which might be release or even patch level specific. Generating
 448 #   the machine code for and analyzing the *whole* program appears
 449 #   to be *extremely* memory demanding while the performance gain is
 450 #   actually questionable. The situation is intensified by the default
 451 #   HP-UX data set size limit (infamous 'maxdsiz' tunable) of 64MB
 452 #   which is way too low for +O4. In other words, doesn't +O3 make
 453 #   more sense?
 454 # - Keep in mind that the HP compiler by default generates code
 455 #   suitable for execution on the host you're currently compiling at.
 456 #   If the toolkit is meant to be used on various PA-RISC processors
 457 #   consider './Configure hpux-parisc-[g]cc +DAportable'.
 458 # - -DMD32_XARRAY triggers workaround for compiler bug we ran into in
 459 #   32-bit message digests. (For the moment of this writing) HP C
 460 #   doesn't seem to "digest" too many local variables (they make "him"
 461 #   chew forever:-). For more details look-up MD32_XARRAY comment in
 462 #   crypto/sha/sha_local.h.
 463 # - originally there were 32-bit hpux-parisc2-* targets. They were
 464 #   scrapped, because a) they were not interchangeable with other 32-bit
 465 #   targets; b) performance-critical 32-bit assembly modules implement
 466 #   even PA-RISC 2.0-specific code paths, which are chosen at run-time,
 467 #   thus adequate performance is provided even with PA-RISC 1.1 build.

 736         #
 737         # a) rely on your compiler default by not specifying one;
 738         # b) specify your target platform explicitly for optimal
 739         # performance, e.g. -march=armv6 or -march=armv7-a;
 740         # c) build "universal" binary that targets *range* of platforms
 741         # by specifying minimum and maximum supported architecture;
 742         #
 743         # As for c) option. It actually makes no sense to specify
 744         # maximum to be less than ARMv7, because it's the least
 745         # requirement for run-time switch between platform-specific
 746         # code paths. And without run-time switch performance would be
 747         # equivalent to one for minimum. Secondly, there are some
 748         # natural limitations that you'd have to accept and respect.
 749         # Most notably you can *not* build "universal" binary for
 750         # big-endian platform. This is because ARMv7 processor always
 751         # picks instructions in little-endian order. Another similar
 752         # limitation is that -mthumb can't "cross" -march=armv6t2
 753         # boundary, because that's where it became Thumb-2. Well, this
 754         # limitation is a bit artificial, because it's not really
 755         # impossible, but it's deemed too tricky to support. And of
