["Uri Shachar (Updated) (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/TS-1102?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Uri Shachar updated TS-1102:
----------------------------

    Attachment: diags_cleanup.patch

Base cleanup patch. Will add 2 more patches to remove the DebugOn macro (which was an unoptimized version of Debug anyways) and remove the obsolete 'prefix' argument.

> The current Diags.h D/EClosure mechanism is obsolete. ATS requires gcc >= 4.1 for all compilation environments, and it includes variadic argument macro support with ##_VA_ARGS_ that deletes the final comma if no arguments are provided.
> Removing the added layer should also improve performance when high volume debugging is turned on.
