      "message": "ART: Implement a fixed size string dex cache\n\nPreviously, the string dex cache was dex_file-\u003eNumStringIds() size, and\n@ruhler found that only ~1% of that cache was ever getting filled. Since\nmany of these string dex caches were previously 100,000+ indices in\nlength, we\u0027re wasting a few hundred KB per app by storing null pointers.\nThe intent of this project was to reduce the space the string dex cache\nis using, while not regressing on time that much. This is the first of a\nfew CLs, which implements the new fixed size array and disables the\ncompiled code so it always goes slow path. In four other CLs, I\nimplemented a \"medium path\" that regresses from the previous \"fast path\"\nonly a bit in assembly in the entrypoints. @vmarko will introduce new\ncompiled code in the future so that we ultimately won\u0027t be regressing on\ntime at all. Overall, space savings have been confirmed as on the order\nof 100 KB per application.\n\nA 4-5% slow down in art-opt on Golem, and no noticeable slow down in the\ninterpreter. The opt slow down should be diminished once the new\ncompiled code is introduced.\n\nTest: m test-art-host\n\nBug: 20323084\n\nChange-Id: Ic654a1fb9c1ae127dde59290bf36a23edb55ca8e\n"

This reduces the\narm64 boot.oat on Nexus 9 by 1.1MiB.\n\nThis CL provides the infrastructure and shows on the arm64\nthe gains that we can achieve by having fixed dex cache\narrays\u0027 layout. To fully use this for the boot images, we\nneed to implement the PC-relative addressing for other\narchitectures. To achieve similar gains for apps, we need\nto move the dex cache arrays to a .bss section of the oat\nfile.
