43d5fb4523 optimisation: try to enable sse3
Effectively all hardware we target includes sse3 instructions at this
point.

630aa5de08 optimisation: switch back to Og for debugging
O0 is catastrophically slow for some of our projects. Don't
unconditionally use O0.
2018-01-24 17:28:33 +11:00
1bde0634b4 warnings: add -Wno-gnu-string-literal-operator-template 2018-01-23 18:54:14 +11:00

8c9ca6a372 optimisation: temporarily disable -ggdb
This works around an ICE with libcruft-util's coord classes and GCC's
trunc_int_for_mode.

9cd8c56cdc 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.

b3d2938410 cxx: quote the filesystem libraries 2017-12-20 16:12:11 +11:00
6576747031 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.

bd4b8328c2 optimisation: remove deprecated clang optimisation 2017-09-12 14:24:59 +10:00
157ff8962c cxx: default to using libcxx where possible
using libcxx alleviates some compilation errors under newer clang and
c++17.
2017-08-07 12:58:10 +10:00
8a83b07ea0 optimisation: use Og instead of O0 by default
O0 is hellishly slow, this is every so slightly less so.
2017-07-04 16:21:00 +10:00
a1d3200fde 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.
2017-07-04 14:20:00 +10:00
929556d677 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
06bb32ff00 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.

cec999bfdf cxx: clear the default cmake cxxflags/cflags
cmake forces some values we don't want. it's better to start from
scratch.

45be843568 search_libs: add comment 2017-02-01 13:45:48 +11:00
4488026028 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.
