With the below patch I've been able to build ports gcc 4.9 on:
OpenBSD 6.4-beta (GENERIC) #219: Sat Sep 8 14:02:06 MDT 2018
[email protected]:/usr/src/sys/arch/alpha/compile/GENERIC
AlphaServer DS10 617 MHz
The patch reduces the optimization level from -O2 to -O1 during the build
to make things work. With this, I was able to build numpy and run the
numpy regression tests succesfully.
ok to commit?
(Note: to test you'd also need to add alpha to GCC49_ARCHS in
infrastructure/mk/arch-defines.mk but that can be committed after the
below goes in)
