search for: notty

I want to expose most of the logic in NoTTI to passes that do not depend on TTI for the purpose of pure IR-level instruction metrics. For example, we don't want the presence of certain "free" intrinsics to affect the patterns handled by canonical transforms. It would still be ok to use DataLayout here, so certain casts are considered free. The idea of "free" here has little

FWIW, this all makes perfect sense from a philosophical point of view. If anything, I think it is absolutely critical to differentiate the very interface this exposes from the TTI interfaces. The latter should be cost functions, that are as accurate as we can make them while remaining largely "conservative" (IE, don't assume any clever brilliance is the chip or backend; what is the

Thanks to you both. On my Linux (centos6) system, I have reproduce a variant of the bug and learned about -plugin-opt=-debug-pass=Arguments which I infer from comments is intended to built arguments to “opt” however I found that some of the arguments don’t seem to be quite correct. I assume this just minor bit rot. bin/opt -o pass1.bc -datalayout -notti -basictti -x86tti -targetlibinfo

Hi, I try to use MemoryDependenceAnalysis in a pass to analyse a simple function: void fct (int *restrict*restrict M, int *restrict*restrict L) { S1: M[1][1] = 1; S2: L[2][2] = 2; } When I iterate over MemoryDependenceAnalysis on the S2 statement, I get the load instruction for the first depth of the array, that’s ok. But I get also the load and store for the S1 statement. I assume the
