This depends on the target, but calls normally have a few operands: + The callee (a register or a global address or

Hi Tim, I'm sorry to bother you again. Since I have met the problem, how to check used registers and avoid clobbering live registers, which you mentioned in the email. I am working in the function X86InstrInfo::storeRegToStackSlot, which is in lib/Target/X86/X86InstrInfo.cpp. And I have an extra problem, may I use MOV64mr and two addReg to set two registers as its arguments? I want to use

Dear Mr. Northover, Thank you for the quick reply. You are correct about the address-mode operands :) . I guess an important detail left out was that the basic block (call it A) that wants to calculate the address of the target stationary trampoline basic block (call it B) will be moved around in memory during run-time. Our earlier solution, before the feature was implemented to move around (A)

Hi all, I met a new problem in the process of my project. I have got an address by mmap. And I want to build a MachineInstr of MOV64mr to move a value to the address. But it seems that the MachinePointerInfo needs a pointer to a Value. So can I create a MachineMemOperand directly with the address (is a long*) ? Or I need to try some other methods? Thanks a lot, Will -------------- next part

Usually I will search the target directory, X86 in your case, to see how MOV64mr is used with BuildMI to generate the instruction I want. 2018-04-16 16:25 GMT+08:00 Will Lester via llvm-dev <llvm-dev at lists.llvm.org>: > Hi all, > I met a new problem in the process of my project. > I have got an address by mmap.

Thanks for your advice. But I have searched X86 and find no more information than I have known. The problem is not to create a MachineMemOperand, but to create a MachineMemOperand with certain address. This scene does not exist in the original code. Since I have to do this in the process of register allocating, inserting IR instruction seems to be infeasible. I have thought of storing the address

Hi Bill, I am using the following version of BuildMI : MachineInstrBuilder BuildMI(MachineFunction &MF, const TargetInstrDesc &TID, unsigned DestReg) I do the following : void createInstrs(std::vector<MachineInstr *>& ilist) { Machine Instr *mi; mi = BuildMI(MF, someTID, somereg);

Hello, I just wrote the code like this: BuildMI(BB, NM::CALL, 1) .addExternalSymbol(("_lvksda_control_marker_" + lexical_cast<string>(bb)).c_str()); and got some unexpected string in the assembler output. The problem is that when external symbol is added to MachineInstruction, MachineOperand is created with the char*

To the R development team; I found an unusual behavior in zoo when I upgraded to R 2.11.0 - it abruptly terminated when I performed certain operations on large zoo objects. I sent an e-mail to Achim Zeileis and he said this was a potential bug that I should report to the R development team. The details are given below in the thread below. Basically, I can crash R with this code: library(zoo)

If I browse to \myRoRApp, I get the "Welcome aboard" screen.

My rails web app (rails 1.2.1) uploads an image from a Java applet by encoding it into the URL. This works fine when I''m using Webrick.

Is there a way to make Mongrel accept a really long URL like

Hi, I have a task to complete and I'm getting stuck. I can't find anything comparable in the documentation. The shortest explanation I can give is as follows: I need to use double-precision floating point values for floating-point multiplies. I'll not go into why: That would take the discussion away from the essential problem. E.g. Replace: fmuls %f20,%f21,%f8 with the
