[Aaron M. Ucko]

Source: ovito

User: debian-hppa at lists.debian.org
Usertags: hppa

Builds of ovito for hppa, m68k, powerpc, and ppc64 (all admittedly
non-release architectures) have been failing lately with variants of

  /tmp/ccA1UlEM.s: Assembler messages:
  /tmp/ccA1UlEM.s:12621: Error: Unknown opcode: `pause'
  src/3rdparty/geogram/CMakeFiles/geogram.dir/build.make:425: recipe for target 'src/3rdparty/geogram/CMakeFiles/geogram.dir/delaunay/delaunay_3d.cpp.o' failed
