[LLVMdev] [PATCH] Add a Scalarize pass
...which is often a good example when it comes to complicated possibilities :-)). It has at least four separate vector extensions: - <2 x float> support from the MIPS V floating-point extensions, carried over to MIPS 32/64. - <8 x i8> and <4 x i16> support from the optional MDMX extension, now deprecated but used on older chips like the SB-1 and (in a modified form) the VR5400. - Processor-specific vector extensions for the Loongson range. - The new MSA ASE. That's a lot of possiblities. Maybe the LLVM port will never support Loongson and MDMX (almost c...

As an alternative, adding Scalarizer and InstCombine passes to SystemZPassConfig::addIRPasses() would probably

Proposal for replacing asm code with intrinsics
Hi, I'm new to Theora and would like to propose several performance optimization using advanced instructions in x86 CPUs (SSE2-SSE4.2). There are several source files in \x86 and \x86_vc which developed using inline assembler. However this cause several maintenance problems: 1) Need to sync gcc & msvc versions 2) Only 32bit environment is supported 3) No support for newer than MMX
