The gcc 4.9 port supports -msse4.2, but our assembler doesn't support (at least some of the) opcodes that it uses.
: Assembler messages: :132: Error: no such instruction: `pcmpistri $2,(%rdi),%xmm2' :172: Error: no such instruction: `pcmpistri $2,%xmm3,%xmm1' :175: Error: no such instruction: `pcmpistri $58,%xmm3,%xmm3' Would it make sense to disable the option in the compiler for now?
