[jira] [Created] (ORC-1021) Add -fno-omit-frame-pointer in RELWITHDEBINFO build

Quanlong Huang created ORC-1021:
-----------------------------------

             Summary: Add -fno-omit-frame-pointer in RELWITHDEBINFO build
                 Key: ORC-1021
                 URL: https://issues.apache.org/jira/browse/ORC-1021
             Project: ORC
          Issue Type: Improvement
          Components: C++
            Reporter: Quanlong Huang
            Assignee: Quanlong Huang


[~drorke] points out that it'd be helpful to add the -fno-omit-frame-pointer option in release builds, which helps to generate flame graphs for deep stacks [1]. 

The option is already used in release builds of Impala and we found the performance penalty is small (IMPALA-4132). As we have two release modes, i.e. RELEASE and RELWITHDEBINFO with symbols, we can add this option to RELWITHDEBINFO builds.
