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