<div dir="ltr"><div>I am not certain if this question is better suited for cfe-dev or cfe-users, so I am starting here.</div><div><br></div><div>I am looking at using Clang to compile to a target that currently has no support. Actual target isn't important, so much as that it isn't currently supported and I am trying to learn the process of retargeting from the ground up.</div>
<div><br></div><div>Obviously, a big step (first?) step is writing a backend for the new target. After that it is necessary to get the C and C++ runtimes working. After that it shouldn't be too hard to get the C and C++ standard libraries working.</div>
<div><br></div><div>What pieces are needed for the who processes? My guess would be the following:</div><div><br></div><div>1. Compiler (Clang and LLVM)</div><div>2. C++ library (libc++)</div><div>3. C library (PDCLib?)</div>
<div>4. ABI (libc++abi)</div><div><br></div><div>Am I missing anything? Are the C and C++ runtimes part of the ABI or are they a different piece? Also, what C library would people recommend using?</div></div>
