[LLVMdev] FunctionPassManager Issue

[Reid Spencer]

On most libc implementations, gets is a macro not a function which is
why the FunctionPassManager can't find it. But, if you were compiling
from C, it should never have been requested as a function. Is this in
LLVM assembly that you tried to call gets? If so, that's the problem, it
doesn't (and won't) exist anywhere. Linux has deprecated use of gets
forever. From the man page:

BUGS
       Never use gets().  Because it is impossible to tell without
       knowing the data in advance how many  characters  gets()  will
       read,  and  because gets() will continue to store characters past
       the end of the buffer, it is extremely dangerous to use.  It has
       been  used  to  break  computer  security.  Use fgets() instead.
