I'm new to linux so be patient. I'm running Ubuntu Hardy and have Wine 1.1.5 installed. After installing Family Tree Maker 2009 successfully, it will not execute. The screen comes up like it is going to start and says the database needs to be compacted and then the screen fades away. I decided to run FTM 2009 from the terminal and see what is happening. Obviously a lot of things.

Here http://llvm.org/docs/ExceptionHandling.html#llvm_eh_selector llvm.eh.selector is declared like this: i32 %llvm.eh.selector <http://llvm.org/docs/ExceptionHandling.html#llvm_eh_selector>(i8*, i8*, i8*, ...) But when clang++ (rev.121360) writes the module with exceptions, it writes it out like this: declare i32 @llvm.eh.selector(i8*, i8*, ...) nounwind Why there is such descrepancy?

Dear lots of people, The first comments on the 3.7 release expressed surprise that there were no changes to the X86 or ARM targets. There had of course been a lot of hard work and many changes, but none of it was mentioned in the release notes. Please help make the release notes more comprehensive this time. The notes are of course not as important as the actual code, but they do get read, and

Hi Gents, For those of us with out-of-tree backends which are not 32bit, the msp430 backend is a useful vehicle for examining changes and testing out ideas. So I was wondering about enabling debug output on the MSP430 backend so that I can illustrate a few issues to Adrian and you on the variable pieces side. (there doesn't appear to be any specific person claiming the msp430 code right

The first time you said “setjmp/longjmp intrinsics” I thought it was a typo, and that you were talking about the C standard library functions. If you’re actually talking about LLVM intrinsics, are they documented? I don’t see any intrinsics with those names in the language reference (https://llvm.org/docs/LangRef.html <https://llvm.org/docs/LangRef.html>). > On Mar 27, 2020, at 3:30 PM,

Hi, I apologize if I'm posting this to the wrong list; if this is the case, please let me know. For some time now, I've been trying to get SEH exception handling to work in LLVM MCJIT (x64). While reading up on LLVM 3.8, I decided to pick it up again, because a lot has changed which simplifies things greatly. As a toy project, I'm attempting to catch an exception that's thrown

https://llvm.org/docs/ExceptionHandling.html#wineh > No variables live in to or out of the funclet can be allocated in registers. I don't think this is quite true. though it might be a useful simplification. Obviously it is true for volatile registers, but I believe the funclet receives a CONTEXT with the nonvolatiles restored. Obviously cumbersome to access, but it lets you enregister

Hi, I'm developing an OpenGL shader-like language, using LLVM as the JIT engine. For some circumstances or exceptions I would like to abort the script, by throwing an exception back to the code that called the ExecutionEngine::runFunction. Initially I had problems throwing exceptions from functions called from the JIT code, where the JIT code would handle the exceptions, but this was solved

Dear LLVM people, I have started playing with LLVM a little bit and I am thinking of using it to write some linear algebra software for my class. First, an off-topic "bug report" (?), I tried using llvm under cygwin with Vista 64 bits, and it hangs during the build process. It works fine under Vista 32 bits, with cygwin. I was reading the documentation and I am very excited by the

Passing extra info on the stack doesn't make much sense because the stack gets popped... Also, note that the unwind instruction is

I'd like to thank Tim and David for answering this and Chenwj for asking. I personally don't know much at all about exception handling in LLVM - it's something that was implemented for my target before I started working on it. The information you provided is concise, clear and a great start for getting a handle on how it all comes together in the back end. In addition to thanking you

Hi Jb, It's good to see someone step up and take a shot as this again. I dropped this because it seems to me it wasn't a high priority task for LLVM/Clang. Implementing SEH is more of LLVM work than Clang work. For 32-bit SEH, there are prologue/epilogue instruction sequence to emit, setting try-level ([ebp-4]), recovering EBP ([ebp-18h]), and all these can only happen in LLVM, not

Hello, Having installed R 2.3 for OS X Tiger 10.4.6(PPC), i tried running the new R.app, but it hangs (spinning beachball). Moreover, i can't install the RGUI from within the R-2.3 DMG, - it tells me i must have R 10.4 installed ! (I have 10.4.6) R 2.3 runs successfully from the command line however. I tried compiling from sources, but Xcode has this error(i.e it can't locate
