<br>
It is needed that lld verifies the input to the linker.<br>
<br>
For example : a x86 ELF file can be given to lld when the target is x86_64. Similiarly with other flavors.<br>
<br>
I was thinking to have a varargs function in the LinkingContext that would be overridden by each of the LinkingContexts to verify files after being read.<br>
<br>
The reader would call the varargs function in the LinkingContext and raise an error if the input is not suitable with the current link mode.<br>
<br>
Thanks<span class=""><font color="#888888"><br>
