[openssl-users] Help compiling on HPUX

Wed Nov 8 17:07:22 UTC 2017

I can confirm that I can compile with no-asm.  That’s a good thing.

I cannot however get any level of optimizations to compile correctly.  This may not be a problem for my use case, but it may be for others.

If I update Configurations/10-main.conf for hpux64-ia64-cc to use +O0, +O1, or +O2 (+O3 was the default) it will trigger the issue.  
  "hpux64-ia64-cc" => {
        inherit_from     => [ "BASE_unix", asm("ia64_asm") ],
        cc               => "cc",
        cflags           => combine(picker(default => "-Ae +DD64 +Olit=all -z -DB_ENDIAN",
                                           debug   => "+O0 +d -g",
                                           release => "+O0"),   #### I changed the value here!

This is also shown in the CFLAGS in the summary output from Configure:

Configuring for hpux64-ia64-cc
CC            =cc
CFLAG         =-Ae +DD64 +Olit=all -z -DB_ENDIAN +O0 -D_REENTRANT

While I can proceed with my project using no-asm, I am willing to try other changes to help the OpenSSL project out to see if the problem is just around one function that cannot be optimized, etc if anyone has any suggestions.  

I'm not sure if the git-hub bug moderators are on this list, so I'll update the bug report there with this new info.

    Dan, you did not specify the platform.  I have not built on RISC since OpenSSL 0.9.8.
    I have built OpenSSL 1.0.2k on Itanium as follows.  I mostly agree with Michael, 
    but have not backed off optimization quite as far.  Note that my use cases do not
    include encrypting/decrypting large payloads, so can get away with reduced
    performance to get correct results (i.e., pass the tests).

    I had to edit util/selftest.pl for the compiler's identification output
    and because the ar(1) command will not accept /dev/null as an input file.

    I also eliminated a lot of the tests in test/cms-tests, because we do not use the 
    modules being tested.  (They were failing.)  I can believe these might work with 
    lower optimization such as Michael recommends.

    Below is the Configure output.  Hope this helps.
