[LLVMdev] Turning on/off sub-target features (e.g. Altivec on PowerPC)
Hello,
I'm using Mono with experimental LLVM backend support on PowerPC. I noticed
that although LLVM's IR contains SIMD instructions the assembly produced
doesn't contain any Altivec instructions and my PowerPC970 machine of course
has Altivec support. Isn't there some kind of autodetection? I searched in
Target sources but only found out that Altivec is disabled by default.
Can I turn Altivec support on (and off, I need both cases) from the code?
