Log:<br>
Fix the bootstrap of CompilerRT with host compilers that don't support<br>
emulating 128-bit arithmetic on 32-bit x86 targets. This should get the<br>
bootstrap back for GCC 4.6 at least.<br>
<br>
Suggestions on better ways to do the detection here are welcome...<br></blockquote><div><br></div><div>It makes me sad that we're now building a runtime library which will, by default, abort unhelpfully if it sees an int128. I'll look into making that better.</div>
<div><br></div><div>It'd be great if we could build the compiler-rt with the just-built Clang where possible (if $build == $host and we have a Clang checkout in the source tree), but I don't know how hard it'd be to get the build system to handle that.</div>
