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

Hi, If we add multiple loop passes to the pass manager in PassManagerBuilder.cpp consecutively without any func/module pass in between, I used to think they would belong to the same loop pass manager. But it does not seem to be the case. For example for this code snippet PM.add(createIndVarSimplifyPass()); // Canonicalize indvars MPM.add(createLoopIdiomPass()); //

I want the optimization to be turned on at -O1 and above. In my case, it is a target independent back-end pass.

What if in the registration interface we had three options: skippable, not skippable, and run at OptLevel::None. We'd need some way to communicate the OptLevel::None to the pass, but that doesn't seem terrible. -Andy -----Original Message----- From: David Greene [mailto:dag at cray.com] Sent: Monday, October 01, 2018 7:01 AM To: Fedor Sergeev <fedor.sergeev at azul.com> Cc:

I found the following problem when I try to debug "target does not support mc emission" in linux (the same code executes OK in windows): Below is a snippet extracted from this method, if (UseMCJIT && ExecutionEngine::MCJITCtor) { ExecutionEngine *EE = ExecutionEngine::MCJITCtor(M, ErrorStr, JMM, OptLevel,

Hi, I'm trying to build code for very short function and I encounter with a problem (or bug) in DAG selection algotithm. I have a node that was created in Combine(BeforeLegalizeTypes) and should be optimized in Combine(AfterLegalizeTypes). But LegalizeTypes() did not change anything and Combine(AfterLegalizeTypes) was not called. Vector legalization that comes afterwards just scalarized the

Hi All, I want to use Optimization Level options in tailDuplicate() API from TailDuplicator.cpp file to restrict splice() function. With -Oz option this splice() API is duplicating the RET instruction in predecessor blocks. Could anyone please give your suggestions to get OPTLevel Options(which object will carry OptLevel Options in this stage?) in this level. Thanks & Regards, Ramakota

Hi Ankur, > The flags "-view-sched-dags".. described in the doc doesn't seem to work. ( > "llc -help" doesn't list it ). as far as I remember, displaying DAGs during compilation is only enabled in "debug builds" [1] of LLVM. You probably have to re-configure and re-compile LLVM to enable this feature. Best regards, Christoph [1]

Dear R listers -- I have several questions about using the ppr command in the modreg module. I discovered -- quite by accident -- that if I re-order the data, I obtain different results. The output below shows what I mean. I have two datasets (dataset1 and dataset2) that are identical (tested using proc compare in SAS) except for the fact that the records are in different order. Below I have

The “Program” class keeps a pointer to the “nv50_ir_prog_info” structure, so you could just use that in the “Program::print()” function, rather than passing the flag as an argument to “print”.

...when the optimization level is set to zero, i.e. the initial ridge terms are accepted without refitting. I encountered this problem in an out-of-sample prediction exercise using predict. But further investigation suggests the issue is with the ppr fit and predict just sppeds up the crash. The other optlevels seem to be OK, but I have not done enough testing to say for sure. I'm using 2.11.1 under the 32-bit Windows XP. I've also tested the codes under a 64-bit Ubuntu and the same problem occurred. By the way, right before Rgui shuts down, the pop-up window suggests it's a runtime error in...

I am trying to understand the SelectionDAG construction from LLVM IR. I have gone through the doc "The LLVM Target-Independent Code Generator" on LLVM site. This gives a great initial overview. However I am unable to catch the actual control flow for the llvm->selectionDag conversion. The flags "-view-sched-dags".. described in the doc doesn't seem to work. ( "llc

getOptLevel() gets the level from TargetMachine which is created by the Backendutil in clang with either "Default", "None" or "Aggressive". Threre is no correspondence for "Less". This boils down to , if I pass "-O1", the Target Machine is created with CodeGenOpt::Default. I am available on IRC @ sgundapa. -----Original Message----- From:

Hi,I've been trying to code through CommandLine the options I want my tool accepts, but I find quite impossible to achieve robustly what I need .Look, I want the tool accepts a list of arguments in a particular order. For this goal, I know the cl::Positional flag. But, the problem is that the first argument must be one of a set of options (like a kind of subcommand of the tool). In my case,
