[LLVMdev] Question about Pre-RA-schedule in LLVM3.3
...chine register dependence will disappear, this sequence instructions would be executed with less stalls and cycles. However, in the latest version of LLVM, the Pre-RA-sched builds a scheduling graph(original graph) which is shown following. //original graph ----> data flow ====> control flow load1 ----> store1 ====> load2 ----> store2 ====> load3 ----> store3 //end original graph So, Pre-RA-sched is unable to schedule apart load/store instruction pair. Due to LiveRange in the Register Allocation stage, all load/store instruction pair are allocated the same register. If we cha...

[LLVMdev] Question about Pre-RA-schedule in LLVM3.3
...instruction. So, I insert a breakpoint in BuildSchedGraph function in ScheduleDAGSNodes.cpp to debug the source code. Then I get schedule graph of this basic block: Like the above graph, Pre-RA-sched(ScheduleRRList.cpp) is unable to insert the 3th SDNode(load2 instruction) between the first SDNode(load1 Instruction) and the second store1 SDNode. Then in the register allocation step, the pair instruction are allocated same register. However, if we build a schedule graph like the following: I think that Pre-RA-sched has change to schedule apart load1 and store1, the same to load2 and store2. Have...

PCA analysis
Hi, I have a problem with making PCA plots that are readable. I would like to set different sympols instead of the numbers of my samples or their names, that I get plotted (xlabs). How is this possible? With points, i don´t seem to get the right data plotted onto the PCA plot, as I do not quite understand from where it is taken. I dont know how to plot the correct columns of the prcomp

munin module: manage clients and server''s config
Hello all. Probably this question has already been posed in the context of another software, but I am unable to find it. I would like to implement a module which should manage munin-clients as well as the munin-server. Here is what I am thinking about implementing: - There are two classes: munin::client and munin::server - munin::clients'' configuration will be managed automatically.

About CodeGen quality
Hi Mats, It's private backend. I will try describing what I am dealing with. struct S { unsigned int a : 8; unsigned int b : 8; unsigned int c : 8; unsigned int d : 8; unsigned int e; } We want to read S->b for example. The size of struct S is 64 bits, and seems LLVM treats it as i64. Below is the IR corresponding to S->b, IIRC. %0 = load

[RFC] Coding Standards: "prefer `int` for regular arithmetic, use `unsigned` only for bitmask and when you intend to rely on wrapping behavior."
Hi, The LLVM coding style does not specify anything about the use of signed/unsigned integer, and the codebase is inconsistent (there is a majority of code that is using unsigned index in loops today though). I'd like to suggest that we specify to prefer `int` when possible and use `unsigned` only for bitmask and when you intend to rely on wrapping behavior, see:
