<p class="MsoNormal">Hello,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I have a quick question about the LLVM-CBE ( C Backend ). I know it’s been deprecated and removed from the LLVM package for quite some time now but I am hoping that someone on this mailer still knows something about it or can point me
to the right place.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I am trying to convert a C++ file/application to IR and back to C ( or C++ if possible ). I am forced to take this approach due to the restrictions placed on me by some 3<sup>rd</sup> party tools that are also involved. I’ve been playing
around with LLVM 3.7 & the CBE because there is some community support for this version and I have successfully managed to convert a C file/program to IR and back again. However the C backend fails to generate proper/compile-able code when trying to convert
a C++ file to IR and then back to C; I get a number of undeclared variables at compile time (not link time). Judging by the generated C output and the error produced it ‘looks’ like the CBE is at fault.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">So my question is, Can the LLVM-CBE tool support the conversion back to C code when you feed it IR generated from a C++ file/code ? Has anyone had any success with this? What are some of the common problems? Any other advice or guidance
on how to achieve this would be greatly appreciated.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Thanks in advance for the help!<o:p></o:p></p>
