Collecting Information for LockLint

The compiler gathers the information used by LockLint. More specifically, you specify a command-line option, -Zll, to the C compiler to generate a .ll file for each .c source code file. The .ll file contains information about the flow of control in each function and about each access to a variable or operation on a mutex or readers-writer lock.

No .o file is produced when you compile with the -Zll flag.
