What is the benefit of performing memory leakage test using QAC or PC Lint or any static analysis tool?

During embedded software build, build tools calculate RAM usage. Let's say RAM usage at build time is 80%.

By running memory leakage test using some static analysis tool, what input needs to be provided to this test? What will be the output of this test?

The RAM size is 131 KB or 134,144 bytes

What will be the RAM usage after combining RAM usage provided by build tools at build time and memory leakage information provide by memory leak test?

Hello!
Ram leakage happens only if you allocate memory at runtime and don't release it. Not sure of what you are
developing, but if you just have 128k RAM, you may consider building your entire program / firmware without
live memory allocation.
