Hi Everyone,
gcc117 and gcc118 are Aarch64 with CRC and Crypto extensions:
gcc118:~> cat /proc/cpuinfo | grep -i features
Features : fp asimd evtstrm aes pmull sha1 sha2 crc32
However, the default gcc-4.8 is a bit old and cannot handle options
for the extensions:
gcc118:~> g++ -DNDEBUG -g2 -O2 -march=armv8-a+crc+crypto -fPIC
-pipe -c blake2.cpp
blake2.cpp:1:0: error: unknown feature modifier âcrc+cryptoâ
There is a gcc-5 available:
gcc118:~> find /usr/bin -name 'gcc*'
/usr/bin/gcc-5
/usr/bin/gcc-ar-5
/usr/bin/gcc-nm-5
...
But its missing the c++ version of the compiler:
gcc118:~> find /usr/bin -name 'g++*'
/usr/bin/g++-4.8
/usr/bin/g++
Would it be possible to have g++5 installed on gcc117 and gcc118?
It looks like the same issue exists on gcc113-116, but those machines
are X-Gene Mustang's. The X-Gene Mustang's lack the cpu features of
interest, so g++5 is not needed for testing on those boards.
Thanks in advance.
