Thanks for your reply, Philip. You are right, when I use LLVM-3.8, the 'argmemonly' shows up. Previously, I use LLVM-3.7. I think idempotent is what I want. Can you tell me how to add idempotent attribute to the function? Thanks.

Tks Tom, That is my confusing part. How can I make it to "access memory” so it will HasChain? Is there any flag set like in typeProfile, Node, instructions? myLoad, mayStore, SDNPHasChain? -kevin On Jul 18, 2014, at 4:26 PM, Tom Stellard <tom at stellard.net> wrote: > On Fri, Jul 18, 2014 at 04:15:45PM -0400, kewuzhang wrote: >> sure! >> >> class

en! my test is : %r1 = call<float> @test.adddiv( <float> %r0, <float>* %p0). since >> but somehow it always fall into INTRINSIC_WO_CHAIN category. (caught it in lowering..) I think it doesn’t have chain in initial DAG. unfortunately the intrinsic “test.adddiv” is defined by me for now. not sure how to make it has a chain. kevin On Jul 18, 2014, at 3:06 PM,

Dear all, I want to create filename from a loop, say, i=(1:10), and the final names will be file1.csv, file2.csv, file3.csv in Python, it seems easer as - "file"+str(i) +'.csv , but how can i do in R > list = as.character(1:10) > list [1] "1" "2" "3" "4" "5" "6" "7" "8" "9"

Hello, can anyone help me calling native functions from LLVM-Bytecode functions run in the JIT? I have a program which creates an LLVM execution engine and adds modules and functions to it on the fly. I need to call some native functions of my program from bytecode functions which causes some troubles as it appears not to be documented. My test scenario works like the following: I have

Hi, Diego, Thanks for your quick reply. Inserting a copy instruction may not work here because I have a limitation of virtual register number. I need to assign registers with ssa form to registers without ssa form. I will look the source code you point out.

Hi, All, I want to lower 64 Bits constant such as 'long' and 'double'. So I define them like this: def CONSTI64 : InstFOO<(outs GRWideRegs:$dst), (ins i64imm:$src), "const-long $dst, $src", [(set (i64 GRWideRegs:$dst), imm:$src)]>{ let isMoveImm = 1; } def CONSTF64 : InstFOO<(outs

There's been some recent noise on the mailing list about requiring -fno-rtti; http://lists.llvm.org/pipermail/llvm-dev/2015-August/089010.html Could that be it?

Hi, Assume I define registers R0...R15 and two register classes RegA and RegB. RegA contains R0 to R7 while RegB contains R0 to R15. Then I check the machine instruction, it seems that in some cases, the %vreg0 belongs to RegB; in other cases %vreg1 belongs to RegA_RegB. Can you tell me how TableGen decides which is which? At first, I guess &verg0 will be assigned by R8 to R15 only so that
