[LLVMdev] LLVM ERROR: Cannot select

[Zhiyuan Ren]

Duncan,

Thanks for getting back to me. I am not sure how to find the original
bitcode (and related Ada source code) that causes the truncate. This is the
error message that gcc gave me when I tried to compile an Ada source file
using dragonegg plugin (gcc -c -fplugin...).
