Hi everyone, For reasons beyond the scope of this message, I'd like to append a NULL element to the end of a list. tmp0 <- list(a=1, b=NULL, c=3) append(tmp0, c(d=4)) ## works as expected append(tmp0, c(d=NULL)) ## list with a/b/c only Given that I could use tmp0$a <- NULL to remove 'a', I seem to understand why appending NULL returns me the original list... But how should I

Hello, I am working on a AVR backend and have a version up and running that will convert LLVM IR code to assembly code for my target. I have written a bunch of instructions from the AVR Instruction Set in AVRInstrInfo.td and not much else. In a simple test case I am attempting to compile (if that is the word you are supposed to use for this operation) test.ll: define i8 @foo(i8 %a, i8 %b) {

I'm cross-compiling for MIPS. The test-case is as simple as it can be: void foo() {} $clang -target mips64-octeon-linux -c -B path/to/cross/compiled/mips/assembler a.c And then I look at the object file: $ nm a.o 0000000000000020 t $tmp0 0000000000000000 T foo I would like to know what "$tmp0" is. Furthermore, if I pass -g to clang, I see a whole bunch of such symbols. Some of

It seems that Tablegen is generating intrinsic ID's off by in DAGISel.inc In DAGISel.inc, I have the following pattern: int64_t CN1 = Tmp0->getZExtValue(); // Pattern: (intrinsic_w_chain:f32 103:iPTR, GPRF32:f32:$src0, GPRF32:f32:$src1, GPRF32:f32:$src2) // Emits: (MACRO_FMA_f32:f32 GPRF32:f32:$src0, GPRF32:f32:$src1, GPRF32:f32:$src2) // Pattern complexity = 8 cost

Hi All, I am creating an instrumentation pass using LLVM libraries. I am using clang++ (version 2.9) to compile cpp code into LLVM bit code. When I generate the llvm bit code using clang++ using -O3, I get many instances of instructions that look like the following. br i1 icmp ne (i8* bitcast (i32 (i32)* @pthread_cancel to i8*), i8* null), label %bb23, label %bb25 Here three LLVM instructions

Are you using isTarget = 1 in your intrinsics file?

Hello. I am playing with LLVM and trying to make Z80 (Zilog Z80) backend. The source code is attached. I have succesfully made some simple test. But now I have problem with ADD instruction. The source C code is: typedef struct { unsigned char id1; unsigned char id2; unsigned char id3; } testS; void simple() { testS test; test.id1 = 0x40; test.id2 = 0x80; test.id3 = 0xc0; } It

What? Yet another EH proposal?! This one is different from the others in that I'm planning to start implementing this shortly. But I want your feedback! I've all ready gotten a lot of feedback from Chris, John, Jim, Eric, and many others. Now is your turn! Please read this proposal and send me your comments, suggestions, and concerns. -bw

Hi Peter, I think the problem is that you did not explicitly define stack alignment in Z80TargetMachine.cpp DataLayout("e-p:16:8:8-i8:8:8-i16:8:8-i32:8:8-n8") Try to add S16 to the string if your stack is 2-byte aligned. Refer to http://llvm.org/docs/LangRef.html#datalayout . If it does not work, try to specify the layout in the input module using target layout directive. David On

Hello! I get some odd behaviour using my structs: "myKernelMap" = type {int (sbyte*)*, int ()*} "Kernel" = type {"myKernelMap"*} The second member ( int()* ) is a pointer to the %getchar() function. I want to call getchar using this function: int "callmyKernelgetchar_kernel"("Kernel"* "myKernel") { "PTRMAP" =

Each MountPoint has a different URL, but in the ways that I have described, you don't use it like that. You can have 2 or 3 MountPoints but, one you can just serve as a fallback for all 3 of them. Let's take this example for a few seconds. Say for example, if you had, "http://yourdomain.com:8000/mount1" that will just serve as the listener MountPoint. "/mount2"

Hello. I have played with DataLayout and found a solution with is uknown to me. I added S16 and also s0:16:16, but it had not worked. Then I found that in Z80FrameLowering.h I am calling TargetFrameLowering with stack aligment set to 8. So I changed it to 2 bytes. But this also didn't help. Then I changed llc to show TargetDataLayout and found that a option is set to a0:0:64. So I changed

Dear LLVMers, My name is Raphael Ernani, and I am doing my MsC at the Federal University of Minas Gerais, Brazil. I have been using LLVM for a while, and I would like to participate in this year's Summer of Code. One particular idea, in your "open projects" page caught my eye, and I decided to write a proposal about it. The line that I liked in the page was "Create an LLVM

Hi Bill, there are a couple of things I didn't understand about your proposal, for example how it interacts with inlining, whether it is feasible to do the "turn invoke-of-Unwind_Resume into a branch" optimization and also whether in "resumedest" you still plan to use _Unwind_Resume to continue unwinding up the stack. Could you please show what the LLVM IR would look like

There is no dedicated instruction for this, so just combine it with the constant offset.
