optimisation: switch back to Og for debugging
...
O0 is catastrophically slow for some of our projects. Don't
unconditionally use O0.

optimisation: temporarily disable -ggdb
...
This works around an ICE with libcruft-util's coord classes and GCC's
trunc_int_for_mode.

optimisation: re-enable fipa-pta under GCC
...
It appears codegen works again? Perhaps we were running into a seperate
issue and fipa-pta always worked.

optimsation: prefer -O0 over -Og
...
Og optimises out too many variables to be useful in a large percentages
of the cases. Instead use O0. If we need to revert to Og we'll instead
introduce a new flag.

cxx: default to using libcxx where possible
...
using libcxx alleviates some compilation errors under newer clang and
c++17.

optimisation: use Og instead of O0 by default
...
O0 is hellishly slow, this is every so slightly less so.

nc: request thread support by default
...
we need this for util::job::queue which is in pretty much everything, so
we may as well globally enable threading.

warnings: temporarily remove fallthrough warning
...
we use fallthrough fairly liberally in some bitwise and crypto
codepaths, and keeping this warning message (particularly in debug
builds where we use Werror) is painful.
2017-06-13 14:11:36 +10:00

warnings: disable unsafe-loop-optimisation
...
This warning caused too many false positives with range-for and other
language constructs and was very rarely actually helpful. Disable for
the time being.

cxx: clear the default cmake cxxflags/cflags

cmake forces some values we don't want. it's better to start from
scratch.

search_libs: also set a _FOUND variable
...
There was no way to differentiate between not needing any library for a
symbol and not finding a symbol. So we add a _FOUND variable indicating
whether the symbol was discovered.
