Author: dexonsmith Date: Thu Oct 2 16:56:57 2014 New Revision: 218914 URL: http://llvm.org/viewvc/llvm-project?rev=218914&view=rev Log: DI: Fold constant arguments into a single MDString This patch addresses the first stage of PR17891 by folding constant arguments together into a single MDString. Integers are stringified and a
\0character is used as a separator. Part of PR17891. Note: I've attached my testcases upgrade scripts to the PR. If I've just broken your out-of-tree testcases, they might help. Among other things, this commit broke the Ocaml debug info test [1]. It's not obvious to me how to fix it (I don't speak Ocaml). Anyone know what to do? (Is it reasonable for me to just XFAIL it, file a PR, and move on?) [1]: http://lab.llvm.org:8011/builders/llvm-hexagon-elf/builds/11579
I have a guess (patch below), which I'll roll into my next attempt once I've sorted out the other buildbot failures. Note that r218914 had the first hunk, but missed the second.
In the meantime, if anyone that speaks Ocaml can take a look, I'd appreciate it.
