- added dirty llvm11-support patch, now at least builds with llvm 11

[packages/beignet.git] / cflags.patch

Description: Set compiler flags

Respect CFLAGS,CXXFLAGS,LDFLAGS (security hardening etc.)
Be verbose
Disable non-policy-compliant instruction set assumptions (slows the
OpenCL compiler by ~few%, no effect on OpenCL execution speed)
