search for: optimiziations

...lac encoding and decoding algorithm on the VisualDSP platform. Do you know if it's already existing a flac version for that? I'm trying to estimate the computational cost of FLAClib on blackfin. Do you know some profiling information for blackfin? I saw the assembler code for CPU dependent optimiziations. Is there something similar for blackfin? I couldn't find it.

I am having trouble understanding the relationship between LLVM identifiers, stack (alloca) and variables. In particular, when I need to create a variable, what should I use? For instance, consider the following C-like language snippet: int f() { int i = rand(); if(i > 5) i = 1; return i; } Ignoring optimizations, what should I use to represent 'i'? Online demo gives the following

Hi Again, I'm a little confused regarding what is the exact Orc's functions I should use in order to save the functions code in a code cache so it could be later replaced with different versions of it and I appreciate your help. Just a reminder I want to dynamically recompile the program based on profile collected at the run-time. I would like to start executing the program from the
