similar to: Getting MachineInstr opcode mnemonics as strings

Hi all, I am attempting to implement the "reaching definitions" data-flow algorithm on (X86) MachineBasicBlocks for an analysis pass. To do this, I need to compute gen/kill sets for machine basic blocks. To start with, I am only considering the general-purpose registers, RAX-R15 and their sub-registers. Thus, I need to examine each MachineInstr to determine which register(s) it

Hi all, I am working on creating a MachineFunctionPass to perform an analysis on X86 code. After a bit of trouble, I was able to get my pass compiling and running correctly in llc. However, since a machine pass is compiled directly into the code generator, rerunning "make" across the LLVM build tree involves re-linking most of the major libraries and executables. This is a rather

Hello Community, I have submitted my draft proposal for this project on the summer of code web site and shared it with the community. Please take a look at it and suggest/ comment some modifications. I have already done some study on the relevant code. I will still do some more before the final submission but this is more of designing challenge please help ! Sincerely, *Vivek Pandya*

Is this function required? MCInstrInfo::getName(OpCode) returns the same string, and we have two copies of the string table now. Can MCInstrPrinter refer to MCInstrInfo, and why not? /jakob

Hi everybody, I noticed today that my libLLVM-3.9svn.so has a ~1.7MB .data.rel.ro segment - i.e. data that needs to be touched by the dynamic linker even though it's ultimately read-only, and data that cannot be shared between multiple processes using LLVM. It turns out that a solid ~1.3MB of that data is in the tablegen'd MCInstrDesc tables - there a pointers for ImplicitUses,

I am working on a project where we are integrating an existing pre-RA scheduler into LLVM and we are trying to match our peak register pressure values with the machine instruction schedulers values while using X86. I am finding some mismatches in test cases like the one attached. The registers "AH" and "AL" are live-out but not live-in and I don't see that they are defined

I looked into this at some point and if my memory serves me correctly using MCInstrInfo in the printer would create a cyclic

Sorry for the somewhat nondescript subject line, but I have two questions: 1. What is a really good book on R for a nonprogrammer? 2. How do I open more than one R Graphics: Device 2(ACTIVE). That what is the R command that I can use to keep more than one plot open. I am running a script from a book on Chemometrics that results in more than one graph during the execution, but

Hi all, I am looking at the scheduling model of the ThunderX2. I am trying to figure out the cost of the LDADDALX instruction. The following program’s output is: name LDADDALX; class 872 microops 65535 I would have assumed that the microops are less than 20. The ThunderX2 has a detailed cost model for LSE. Could somebody tell me what I am doing wrong? Cheers, Tom #define GET_REGINFO_ENUM

Hi, I'd like to modify MachineBasicBlock contents within a MachineFunctionPass on the basis of how many CPU cycles the assembly instructions corresponding to the MBB take. I'm using the AVR backend and the number of CPU cycles every AVR assembly operation takes is openly available. Is there any straightforward way of getting the opcode mnemonics corresponding to a MachineInstr? I've

Hello, what do you think about replacing the user documentation page (https://wiki.samba.org/index.php/Samba) with https://wiki.samba.org/index.php/HowTo_Guide? The HowTo Guide is a table of content, we worked out in a past documentation team meeting. Everything from the current user documentation page is already link there and even more. I know that currently there are many red (not

Hello LLVM, I'd like to check TSFlags in my AsmBackend code. However AsmBackend objects don't have a reference to MCInstrInfo, which is the only way I've seen to reach TSFlags. A quickie grep shows that none of the existing targets check TSFlags in their AsmBackends. Is there any reason I shouldn't check TSFlags in AsmBackend? If not, what's the best way to go about it?

Hello everyone! There is segmentation fault during translating a simple function with my backend. Investigation with gdb has shown that address of InstrNameData array in generated file MyTargetGenInstrInfo.inc is out of bounds. Also, if I run llc without -view-dag options, NumOpcodes equals 0 inside llvm::MCInstrInfo::get function, although there are some instructions (they are appeared in

Hi, I'm still having problems implementing my custom inserter in the X86 backend. I found a solution to my last problem (http://lists.cs.uiuc.edu/pipermail/llvmdev/2014-October/078296.html), by using a virtual register. The binary works when it's compiled in -O0, but not in -O1,-O2,... I really can't figure what I'm doing wrong... Any idea? Here is the code of my custom

I am trying to add a Samba 2.0.7 box to an existing domain. The Samba box will not be a domain controller; it's just going to be a nondescript member of the domain. The primary domain controller is running Windows 2000, but is also configured to emulate an NT4 PDC. Our system administrators did their side of things, and told me that user "domain\liblit" now has permission to add
