Hello, I am new to LLVM and doing some experiment with 3.2 on Ada code. Can
anyone help me on the following error message?
Thanks,
ZY

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...). ZY ps, sorry for multiple emails, trying to find out how to reply to a thread in the mailing list On Sat, May 11, 2013 at 12:42 PM, Duncan Sands <baldrick at free.fr> wrote:> Hi ZY, > > > On 10/05/13 22:34, Zhiyuan Ren wrote: > >> Hello, I am new to LLVM and doing some experiment with 3.2 on Ada code. >> Can >> anyone help me on the following error message? >> > > a truncate from an i32 to an f32 is not valid.
