similar to: [LLVMdev] load bytecode from string for jiting problem

I mad the change, and still have the problem. I investigate more the source code of llvm. First, I change isRawBitcode function to print the content of the parameter like this: original: http://llvm.org/docs/doxygen/html/ReaderWriter_8h_source.html#l00081 inline bool isRawBitcode(const unsigned char *BufPtr, const unsigned char *BufEnd) { // These bytes sort

all of: ---- // cout << "lsr: " << lsr << "\n"; llvm::MemoryBuffer* mbjit = llvm::MemoryBuffer::getMemBufferCopy (sr); ------ string lsr = sr.str(); // cout << "lsr: " << lsr << "\n";

This segfault occuring only under valgrind, in shell way, and in gdb way i have Invalid bitcode signature simple_scev_dynamic_array: /home/willy/apollo/llvm/include/llvm/Support/ErrorOr.h:258: storage_type *llvm::ErrorOr<llvm::Module *>::getStorage() [T = llvm::Module *]: Assertion `!HasError && "Cannot get value when an error exists!"' failed.

Hello Willy, Here is the dump from one of my bitcode files: 0000000 42 43 c0 de 21 0c 00 00 25 05 00 00 0b 82 20 00 As expected, 0x42 (= B), 0x43 (= C), xc0 and 0xde are in correct order. In your case, the first byte is read as 37 (= 0x25). I wonder why? When you check the bytes yourself, you get expected results. When the same bytes are read from Stream object, you get a different result (maybe

Hi Rafael, Would you mind waiting for Derek to come back from vacation to discuss this? We do use this code and could improve how it's used and tested within LLVM. Derek is the best person to discuss this, he'll be back in mid-January.

Hi Mircea, If you use an ordinary linker that concatenates .llvmbc sections, you can use this code to get the size of each bitcode module. As far as I know, there's no clean way to separate the .llvmcmd sections without making assumptions about what options were used. // Given a bitcode file followed by garbage, get the size of the actual // bitcode. This only works correctly with some kinds

You should probably pull in some folks who implemented/maintain the feature for Darwin. I guess they aren't linking this info, but only communicating in the object file between tools - maybe they flag these sections (either in the object, or by the linker) as ignored/dropped during linking. That semantic could be implemented in ELF too by marking the sections SHF_IGNORED or something

In MemoryBuffer::init, we have an assert that reads the memory at `BufEnd`, which is one past the end of some memory region: from lib/Support/MemoryBuffer.cpp:45: > void MemoryBuffer::init(const char *BufStart, const char *BufEnd, > bool RequiresNullTerminator) { > assert((!RequiresNullTerminator || BufEnd[0] == 0) && > "Buffer is not

Hello, I need to do a firmware update for my cdrw and because of a missing linux program for doing that I thought of using wine for trying it. I call the programm FlashTool.exe and no error messages occur. (The surface really looks great!) The programm detects correctly the flashable cdrw-drive even with ide-scsi and the non-flashable cdrom. But then when I click on "continue" nothing

I don't think these are really independent. Whether

In order to get llvm to compile on Windows with MSVC 10, I have to disable inline on utostr to avoid internal compiler failure, and disable _xgetbv call in OsSupportsAVX because it's only defined in MSVC 2012 compiler. The first patch (noinline) is known for many months now. I'm a casual llvm user, and don't know the proper channels to go through to submit a patch. Could someone tell

Is there (if not, can we get) the functionality to query for workstations in the local workgroup or domain? Zach

I was writing something using MemoryBuffer, and while looking through its code I came across line 59: assert(BufEnd[0] == 0 && "Buffer is not null terminated!"); I am curious if the MemoryBuffer only supports non-binary, non-null embedded files, or if it supports binary as well. I do not see anything inherently not expecting binary files except for that one line, so I am

>From the DeveloperPolicy.html document I gathered I need to send a patch to this list (which I did); could you clarify if I misunderstood it? The second patch is really trivial and I think it's worth applying - it seems like a typo by someone who tested on MSVC 11 but not 10; or maybe my local instance of MSVC10 is somehow deficient, of course. The first patch is adding MSVC-specific

Hi Rafael, We will try out your patch and check to see how it will fit. You also talked about "It might be even possible to drop the requirement for the size to be known: Replace the call to AtEndOfStream by just trying to read more and checking if it failed, but that is a bit more than I wanted to do for this." That is to remove some calls to getSize()? Is there any expectation that

Hello all Im using sftp 1:4.7p1-8ubuntu1.2 in a batchjob Ive noticed that sftp needs a long time for sending a filelist. The timespan increases exponential if many files are on the remoteserver. for example "ls -la *.txt" needs 10 seconds for 2000 files but needs 50 seconds for 4000 files. For 150.000 Files i have to wait 15 minutes for example but the
