Subject: helper: Update header parser
X-Git-Tag: submit/tizen/20181227.054638~5251
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=ace2744db577eed40ac66c3e1e3f9c3a8f656e68;p=platform%2Fupstream%2FVulkan-Tools.git

helper: Update header parser

The generated version of vulkan.h does not include structure
names on enums or structures. This was throwing off our parser.
This patch adds support to handle that.
