llvm dev - Oct 2017 - Printing Fixups

Hello everyone,

I wish to print the fixups to the standard output. So, can anyone give me
any pointers on how to do that?

For example, if I have the following code, at compile time, the symbol
"printf" will be unresolved and hence, there should be a fixup entry
for
"printf". I need to print all such unresolved symbols to the standard
output.

#include <stdio.h>
int main(int argc, char *argv[]) {
printf("Hello World\n");return 0;
}


Thank you.


Regards,
Malhar Thakkar

It is possible to do this if you use compile or convert your C file to an
LLVM IR file, and then compile that with 'llc -show-encoding.

Here is an example from the AVR backend
