nios2-elf-ld -Ur

hello!

my nios2 system have a problem. the complier can't find the errror when I use a inexistent function,for example:

main()

{

aa();

}

aa is not exsist.

when the complier link the object files, it can't find any error.

I find I use "-Ur" as a one of the parameters of nios2-elf-ld command.

if I delete it, the complier will find the error.

I get the meaning of "-Ur"" from nios2-elf-ld --help

the meaning is "build global constructor/destructor tables"

but I can't understand it.Can you tell me more?

Thank you.
