  "message": "Optimize CPDF_CMapParser\n\nIn this parser, a vector of CodeRange values are built up during\noperations that need to be sync\u0027d with the CPDF_CMap that is being\ninitialized. In the existing implementation, the vector being built as\na member var for the parser, and copying the values over to the cmap\nwhenever there is a change. When profiling, this copy is where the code\nspends most of its time.\n\nThe code has been rewritten to have the parser reference/modify the\ninstance of the vector in the cmap instead of having its own copy. This\nremoves all of the copies and significantly speeds things up.\n\nBUG\u003dchromium:881678\n\nChange-Id: Ib8e75962507ca3d3b1ed066fd1faa4fbb7141122\nReviewed-on: https://pdfium-review.googlesource.com/42350\nCommit-Queue: Ryan Harrison \u003crharrison@chromium.org\u003e\nReviewed-by: Henrique Nakashima \u003chnakashima@chromium.org\u003e\n",
