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

        # Note that -march is not among compiler options in linux-armv4
        # target description. Not specifying one is intentional to give
        # you choice to:
        #
        # a) rely on your compiler default by not specifying one;
        # b) specify your target platform explicitly for optimal
        # performance, e.g. -march=armv6 or -march=armv7-a;
        # c) build "universal" binary that targets *range* of platforms
        # by specifying minimum and maximum supported architecture;
        #
        # As for c) option. It actually makes no sense to specify
        # maximum to be less than ARMv7, because it's the least
        # requirement for run-time switch between platform-specific
        # code paths. And without run-time switch performance would be
        # equivalent to one for minimum. Secondly, there are some
        # natural limitations that you'd have to accept and respect.
        # Most notably you can *not* build "universal" binary for
        # big-endian platform. This is because ARMv7 processor always
        # picks instructions in little-endian order. Another similar
        # limitation is that -mthumb can't "cross" -march=armv6t2
        # boundary, because that's where it became Thumb-2. Well, this
        # limitation is a bit artificial, because it's not really
        # impossible, but it's deemed too tricky to support. And of
        # course you have to be sure that your binutils are actually
        # up to the task of handling maximum target platform. With all

    # Contemporary Android applications can provide multiple JNI
    # providers in .apk, targeting multiple architectures. Among
    # them there is "place" for two ARM flavours: generic eabi and
    # armv7-a/hard-float. However, it should be noted that OpenSSL's
    # ability to engage NEON is not constrained by ABI choice, nor
    # is your ability to call OpenSSL from your application code
    # compiled with floating-point ABI other than default 'soft'.
    # [Latter thanks to __attribute__((pcs("aapcs"))) declaration.]
    # This means that choice of ARM libraries you provide in .apk
    # is driven by application needs. For example if application
    # itself benefits from NEON or is floating-point intensive, then
    # it might be appropriate to provide both libraries. Otherwise
    # just generic eabi would do. But in latter case it would be
    # appropriate to
    #
    #   ./Configure android-armeabi -D__ARM_MAX_ARCH__=8
    #
    # in order to build "universal" binary and allow OpenSSL take
    # advantage of NEON when it's available.
