From: Zachary Turner Date: Wed, 2 Nov 2016 17:05:19 +0000 (+0000) Subject: Add CodeViewRecordIO for reading and writing. X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=7251ede7c5ee82d25e309b6a30952a6b5e7c1f89;p=platform%2Fupstream%2Fllvm.git Add CodeViewRecordIO for reading and writing. Using a pattern similar to that of YamlIO, this allows us to have a single codepath for translating codeview records to and from serialized byte streams. The current patch only hooks this up to the reading of CodeView type records. A subsequent patch will hook it up for writing of CodeView type records, and then a third patch will hook up the reading and writing of CodeView symbols.
