[jira] [Commented] (ARROW-2243) [C++] Enable IPO/LTO

    [ https://issues.apache.org/jira/browse/ARROW-2243?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16527773#comment-16527773 ] 

Antoine Pitrou commented on ARROW-2243:
---------------------------------------

Deferring this to 0.11.0. I'm also not sure this is a good idea: with LTO, build times will explode (for optimized builds), and it also makes us more susceptible to compiler / linker bugs.

> We should enable interprocedural/link-time optimization. CMake >= 3.9.4 supports a generic way of doing this.
