Hello, I am trying to compile the R package on a sun. I get the error message rbitmap.c: In function 'my_png_error': rbitmap.c:73: structure has no member named 'jmpbuf' rbitmap.c: In function 'R_SaveAsPng': rbitmap.c:122: structure has no member named 'jmpbuf' make[4]:*** [rbitmap.lo] Error 1 Has anyone encountered this problem? Any solutions? Is there are compiled binary somewhere that I could use? Grateful for any help. Richard Richard...

...-built code will use llvm's setjmp/longjmp intrinsics. Are the two implementations safely interoperable? Alternatives would be to force the llvm-built code to use the libgc setjmp/longjmp; force the gcc-built code to use a setjmp/longjmp borrowed from llvm; or perhaps make each setjmp tag the jmpbuf to show which flavor of longjmp is required.

Thanks. The reason I ask is because I'm looking at some code that does just that. A single FunctionPassManager is constructed with a dummy Module and createStandardFunctionPasses is called on it. The FunctionPassManager cached and run on Functions in other Modules. So far I haven't noticed any problems but I guess that is because the passes added by createStandardFunctionPasses don't

Hello, I am on the hook to instrument a piece of legacy LLVM IR code, and then we are planning to feed to the SeaHorn framework for some model checking tasks. After the instrumentation, I tried to use llc (version 3.9) to compile the IR code, and it works fine. However, when I try to use llc (version 3.8.1, the default llvm version of SeaHorn) to compile the IR code, it shows the following
