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