--- Comment #4 from Дилян Палаузов <dilyan.palauzov at aegee dot org> ---
Why does COLLECT_GCC_OPTIONS show '-march=x86-64', but
https://gcc.gnu.org/onlinedocs/gcc/x86-Options.html does not show x86-64 as
valid option for -march?
Why doesn't 'make CFLAGS="--verbose -march=native -flto"' work, in terms of
detecting that ssse3 is available and there is no conflict?
The latter prints:
make[3]: Leaving directory '/git/postgresql/src/backend'
gcc --verbose -march=native -flto -I../../src/port -DFRONTEND
-I../../src/include -D_GNU_SOURCE -I/usr/local/include/libxml2 -c -o
