      "message": "Refactor use of __ANDROID__ macro\n\nWe use the __ANDROID__ macro, which is provided by the toolchain, in\nnumerous places. This patch refactors the usage of this by defining a\nnew macro, ART_TARGET_ANDROID, that is being passed during build to\nART_TARGET_CFLAGS in Android.common_build.mk on the same line as\nART_TARGET. The codebase currently assumes that the existence of the\n__ANDROID__ macro implies that we are compiling art for an android\ntarget device. This is because, currently, target builds are compiled\nwith target toolchains that provide the macro, while host toolchains\ndo not.  With this change this assumption is still preserved. However,\nin a future patch we will add the ability to compile art for a linux\ntarget, and in that case the ART_TARGET_ANDROID macro won\u0027t be passed\nanymore.\n\nChange-Id:  I1f3a811aa735c87087d812da27fc6b08f01bad51\n"

      "message": "Relocate DWARF using .oat_patches.\n\nThe current solution is to hard-code knowledge of DWARF in the linker.\nThis works for simple use of DWARF, but breaks as soon as I try to do\nanything more complex.  Making the linker fully support DWARF would be\nnon-trivial task and would be essentially rewrite.  Using .oat_patches\nis much easier solution.\n\nRelocating .debug_* sections required extending .oat_patches to support\nmore sections than just .text.  I have encoded each section as\nnull-terminated section name followed by ULEB128 deltas.\n\nThe ULEB128 encoding shrinks .oat_patches for .text by factor of\nabout 6 with 64-bit compiler, and factor of 3 with 32-bit compiler.\n\nOn the other hand, it grows by the extra .oat_patches for DWARF which\nwere not present before (if debug symbols are included).\n\nOverall, it is still a clear improvement even with the DWARF patches.\n\nChange-Id: I78ffeda0f8a3da03341995a3b5ef15c954e16e9f\n"
