New in v3.1.15

  - unified build procedure fixed
     - build.sh now works for CPUs with and without AES_NI
     - it is no longer necessary to add "-DNO_AES_NI" CFLAG to the
       configure command when building for CPUs without AES_NI.
     - The system will automatically compile for the correct architecture

Thanks!

Strange thing - when I compile with
Code:
./autogen.sh && ./configure CFLAGS="-DNO_AES_NI -O3 -march=btver1" --with-curl --with-crypto && make
on AMD Sempron 145, all works like a charm.

When I use ./build.sh I get an error in compile.

Will try on AMD Phenom II X4 940 and see can I reproduce it.

Edit: ./build.sh fails also on AMD Phenom II X4 940
Code:

The only real difference I see is -march. build.sh always uses native. -DNO_AES_NI is now redundant and should
not be necessary unless -march=native is choosing an incompatible architecture. If that's the case I don't know
what I can do other than document the workaround.

It would be nice to see the compile errors to give me an idea what it was trying to do.

I don't have a non-aesni CPU to test on so it would be nice if you could confirm the capabilities reported when the miner
is started is correct.

Edit: the real errors are further back but didn't cause the compile to fail immediately. Do they compile if you specify
a specific arch but without -DNO_AES_NI?

Following the topic I get the impression that the new changes detects cpu, OS, algo (for AES-NI support)
and if the cpu, OS, algo doesnt support AES-NI it falls back to SSE2.

I will send you PM in a few minutes with the compile logs for both CPU's - Phenom II X4 940 and Sempron 145

That is correct. You need all three to get the best performance.

I haven't found specifically whether either of your CPUs has AES_NI but I suspect not. Try compiling with
-march=core2. It seems to have worked for others.

Both AMD's are without AES-NI support.
-march=core2 works on both, but the compiled binary is about 15% slower than with -march=btver1.

AFAIK its related to SSE implementations on AMD CPU's. So with -march=btver1 which is AMD specific I got the best results.
I tried several -march options, starting with core2 and measured the hashrate on the miner and the pool to choose that one for me.

P.S. Logs are on the way Wink

The logs you sent had no errors, but that's ok I found the nugget in the first line of the previous compile session:
make[2]: *** [algo/echo/aes_ni/cpuminer-hash.o] Error 1
It's clear it was trying to compile AES code.

Also, just to confirm, did you successfully compile without the -DNO_AES_NI flag?

I've drafted the following note to be added to the README file:

I compiled successfully few times on each cpu with this configure
Code:
./configure CFLAGS="-DNO_AES_NI -O3 -march=btver1" --with-curl --with-crypto

The build.sh error at the end is this:

So, what was the setup that was giving the errors? If it works with and without NO_AES_NI?

What was the version of gcc?

I don't understand your question.

If you mean my request above to test it was just to confirm it works on real non-aes HW, which I don't have.

If you are referring to the compile problems in 3.1.14 it was because of a misunderstanding on the maning of __AES__.

If you're referring to you problems with -march=native I have no idea.

gcc v4.8.4

Did any of these answer your question?

Can you run this command on your AMD processors and show me the output?
Code:
gcc -march=native -Q --help=target | fgrep march

Below are examples of how output should look like.

Output on my core2:
Code:
hmage@wraith:~$ gcc -march=native -Q --help=target | fgrep march
  -march=                               core2

On haswell:
Code:
hmage@dhmd:~$ gcc -march=native -Q --help=target | fgrep march
  -march=                               haswell

On ivybridge:
Code:
hmage@education:~$ gcc -march=native -Q --help=target | fgrep march
  -march=                               ivybridge

List of supported architectures on GCC 4.8.4 is here -- https://gcc.gnu.org/onlinedocs/gcc-4.8.4/gcc/i386-and-x86-64-Options.html

This curious. I presume that shows which arch is used by native.

On my skylake I get core2-avx and on my haswell I get corei7-avx.
configure fails with -march=skylake on my skylake.

Yeah! This got me curious and do some tests too.  Cool

On my skylake I get core2-avx and on my haswell sandy bridge I get corei7-avx.

Correction, my sandy bridge shows corei7-avx.
