In progress
Makefile
Xonotic does not build out of the box for POWER, because the Makefile uses the -march compiler flag, which does not exist on PowerPC. It can be fixed by replacing this line in the Makefile:
CFLAGS ?= -pipe -march=native -mtune=native -flto=auto
...with this line:
CFLAGS ?= -pipe -mcpu=native -mtune=native -flto=auto
After making this change, the build instructions should work.
SIMD
Xonotic logs some messages like this:
Skeletal animation uses generic code path (SSE not compiled in) DPSOFTRAST not available (SSE2 not compiled in)
It would be interesting to try porting these SIMD code paths to POWER to see if performance improves.
Benchmarking
See instructions on using Xonotic as a benchmark.
