...'m specially interested in using its optimizer. After apply the optimizations, I needed to create a C/C++ source code equivalent to the original one. I'm periodically updating my local version of the LLVM, and, when I did it today, I couldn't use the llc with -march=c. Looking for the CBackend files, I realized that they were removed from the LLVM folder. I actually don't remember reading about a drop of this capability in any of the devlist messages, so I was wondering if this removal could be only temporary, or there will be no more support for this feature in LLVM. Thanks, --...

NetBSD does not have alloca.h, so CBackend.cpp need to handle NetBSD in the same way as FreeBSD and OpenBSD, as in the attached patch. /Krister -------------- next part -------------- Index: CBackend.cpp =================================================================== --- CBackend.cpp (revision 45865) +++ CBackend.cpp (working copy)...

...test for C backend? We really don't have a particularly good place in the existing test infrastructure for testing the C backend... and there's generally low interest in it. If you have a use for the C backend, I would suggest making sure there are quality regression tests in test/CodeGen/CBackend (so things don't accidentally break), and regularly testing your uses yourself. -Eli

In llvm3.0,I use the llc to convert the IR to C code, But the code lack key words like "struct", Who can tell me how to modify the CBackend, 3Q ^-^ -------------- next part -------------- An HTML attachment was scrubbed...

Hi, I would like to know if the command llc -march=c hello.bc generates a c99 file or not. Is the cbackend target meant to be c99 or normal C. -- Kalyan Ponnala phone: 8163772059 -------------- next part -------------- An HTML attachment was scrubbed...

Hi, I have a version of the old CBackend which is working with the current trunk. I am in the progress of rewriting it into a new version but that project is not going as fast as I would hope as I have been distracted by other tasks with higher priority lately. Anyway, for those interested, I can provide patches, optionally separated in...

Hi, LLVM C backend as of revision 136600 suffers from the following issues: * Forward structs declarations block is missing (it was there previously, why was it removed?) * Anonymous container structs are not generated for array types, resulting into declarations being placed directly into functions prototypes (previously it was not happening as well) I'm not very familiar with llvm

Hi. I am interested in using the CBackend of LLVM. I have read about the problems with the current version and that David Greene has started a reimplementation. Can you tell me about its current state? Furthermore, I use Microsoft Visual Studio. The "Getting started with MVC" documents for release 2.8 say "To emphasize,...

Hi, Please see the collection of test cases attached. To build everything execute make in the top directory. Files with logs show how compilation fails/succeeds, depending on patched/unpatched version of llvm. Could we setup this test suite as a regular test for C backend? Thanks, - D. 2011/8/5 Dmitry N.

Hi I currently would like to find out the signedness of a instruction. But looking at the CBackend, it looks as if it is not that simple? So i have two questions: Is there an easier way than guessing as it is done in the CBackend? Is there a reason for that signedness is not part of the instruction type? Best regards ST
