This simplifies integration with the C API, which does not already expose a mechanism for supplying a custom memory manager.<br><br>The second patch exposes the MCJIT via the C API, and also exposes the NoFramePointerElim option. The manner in which options are exposed is designed for forward compatibility; you supply an options struct along with a size which you zero-fill prior to manipulating. This is similar to the idiom I've seen used in other C APIs like BerkeleyDB. I considered having separate C function calls for each option, in the style of the ExecutionEngineBuilder API - but while that idiom feels right to me in C++, it feels less C-like. As well, the current options approach exposes not just parts of the Builder but also part of TargetOptions (namely, NoFramePointerElim). It's also more concise in practice.<br><br>I plan to expose more innards through the LLVMMCJITCompilerOptions in the future. I'd be happy to do more of that in one go if that was preferred; but I thought that a baby step would be the best thing for now.<br><br><span><mcjit-default-allocator.patch></span><span><mcjit-llvm-c.patch></span><br><br>-Filip<br><br>_______________________________________________<br>llvm-commits mailing list<br><a href="mailto:llvm-commits@cs.uiuc.edu">llvm-commits@cs.uiuc.edu</a><br><a href="http://lists.cs.uiuc.edu/mailman/listinfo/llvm-commits">http://lists.cs.uiuc.edu/mailman/listinfo/llvm-commits</a></div></blockquote></div><br></div></body></html>
