search for: aggressively

Anyone know if it is possible to control how aggressively the "Aggressive" mode behaves. Meaning, is it possible to dial back the aggressive mode to have a happy medium between Regular and the Aggressive defaults. I have a situation where Normal echo cancellation is not quite enough, however when I turn on aggressive mode We are attacking it...

...ses of CSRs in the entry block. So CSR spills/reloads are executed even when the early exit block is taken. int getI(int i); int foo(int *P, int i) { if (i>0) return P[i]; i = getI(i); return P[i]; } It's not that hard to find such cases where RegAllocGreedy aggressively allocates a CSRs when a live range expands across a call-site. That's because of the conservatively initialized CSRCost, causing RegAllocGreedy to strongly favour allocating a CSR over splitting a region. Since allocation of CSRs requires the cost of spilling CSRs, allocating CSRs is not alway...

Hi list members, I saw a couple lavaan posts here so I think I?m sending this to the correct list. I am trying to run a multigroup analysis with lavaan in order to compare behavioural correlations across two populations. I?m following the method suggested in the paper by Dingemanse et al. (2010) in Behavioural Ecology. In one of the groups, lavaan returns negative variance for one path and I?m

Is there a way to set how aggressive the inliner pass (createFunctionInliningPass) without going through the command line interface? Is there any reason InlineLimit isn't an argument to the createFunctionInliningPass function? Thanks, Robert

I think you both got me on the wrong side, though I admit my email wasn't clear. I didn't mean to suggest changing codegen for debug purposes only, but on -O1 to be less

This is probably not an issue for x86_64, which supports natively all types, but it is a real one

I like to propose a new loop multi versioning optimization for LICM. For now I kept this for LICM only, but it can be used in multiple places. The main motivation is to allow optimizations stuck because of memory alias dependencies. Most of the time when alias analysis is unsure about memory access and it says may-alias. This un surety from alias analysis restrict some of the memory based

Hi, I have a new variant of Aggressive Dead Code Elimination that also removes dead branching. It is designed to minimize the cost of control-dependence analysis in the common case where almost the entire program is live. It also can optionally remove dead but may-be-infinite loops. When enabled for –O3 (replacing current ADCE pass) and removing loops, impact on SPEC2006 is in the noise but it

...a non-goal. > Also, as a bit of a teaser, I think Richard Smith is going to be looking into providing much more extensive optional *checking* of undefined behavior. Essentially, '-fcatch-undefined-behavior' may grow some serious teeth. This should allow users to check their code fairly aggressively for UB but not needlessly punish code or those debugging code. -------------- next part -------------- An HTML attachment was scrubbed...

Hello all! I would like to start off by saying that I am still really new to the vast world of R so please excuse my very limited vocabulary in the program. I have collected data from monkey videos and would like to setup some model(s) in R that can help with my hypotheses. I am having trouble figuring out which statistical tests/models to use for my two hypotheses. #1: Comparing the presence

I see the BackendUtil.cpp of Clang creates the TargetMachine with the optimization level based on below mentioned logic CodeGenOpt::Level OptLevel = CodeGenOpt::Default; switch (CodeGenOpts.OptimizationLevel) { default: break; case 0: OptLevel = CodeGenOpt::None; break; case 3: OptLevel = CodeGenOpt::Aggressive; break; } As per my understanding, the correspondence between
