The current implementation simply reads the value given in the d_ptr field and writes the pointer address to that location. However, this value has to be adjusted to reflect the real load address of the binary. Otherwise the linker will write to a faulty location possibly resulting in a crash when linking a MIPS binary that includes DT_MIPS_RLD_MAP. This change corrects that problem.\n\nChange-Id: I1a91874f7ab47289001fe72d9016660c14c70362\nSigned-off-by: Benjamin Adolphi \u003cb.adolphi@gmail.com\u003e\n" }, { "commit": "c62b8a4d3f73b070099d9aa594a261b5250d6cc9", "tree": "10875d7828fe4fa26c4e96b828f82d6601ba0683", "parents": [ "7b3876e2516fd55d61a48cb23a7080ea88b9617b" ], "author": { "name": "Elliott Hughes", "email": "enh@google.com", "time": "Wed Feb 12 17:17:41 2014 -0800" }, "committer": { "name": "Elliott Hughes", "email": "enh@google.com", "time": "Wed Feb 12 17:17:41 2014 -0800" }, "message": "Remove unused variables not spotted by GCC.\n\nChange-Id: I49a16096bc0f41f3ad0007249161e8bdfcf3438c\n" }, { "commit": "faf05bacd45719291b371f24b1b89543881b37f6", "tree": "5ea47b891e7b65d94af4bd558d2a1817247e74de", "parents": [ "577fce0108feda58296beacfbc0ada4a6d6afbc2" ], "author": { "name": "Elliott Hughes", "email": "enh@google.com", "time": "Tue Feb 11 16:59:37 2014 -0800" }, "committer": { "name": "Elliott Hughes", "email": "enh@google.com", "time": "Tue Feb 11 17:33:49 2014 -0800" }, "message": "Clean up all the lint cpplint can find in the dynamic linker.\n\nChange-Id: Ic9ee7153817c22a252cc4b309283e355b623cab9\n" }, { "commit": "9918665a45095ad135576f005c0e5307feb366a1", "tree": "fdef48d2a8c74a2bc8dfd17fd25527ed98b96b3a", "parents": [ "c856baeeade96c167400f179a86d50c426e81788" ], "author": { "name": "Chris Dearman", "email": "chris.dearman@imgtec.com", "time": "Thu Feb 06 20:36:51 2014 -0800" }, "committer": { "name": "Elliott Hughes", "email": "enh@google.com", "time": "Tue Feb 11 15:33:14 2014 -0800" }, "message": "[MIPS64] Dynamic linker\n\nChange-Id: I937c7c776cae3d66e214798d5217a922cd106bfc\nSigned-off-by: Chris Dearman \u003cchris.dearman@imgtec.com\u003e\nSigned-off-by: Duane Sand \u003cduane.sand@imgtec.com\u003e\n" }, { "commit": "0266ae5f884d72da58f33a072e865ba131234a5e", "tree": "48763b706806f544b1dec0ef98261bed6f21dee2", "parents": [ "eeb9a9f59a58a2f042e8f6fd1a4911ae92ac5493" ], "author": { "name": "Elliott Hughes", "email": "enh@google.com", "time": "Mon Feb 10 17:46:57 2014 -0800" }, "committer": { "name": "Elliott Hughes", "email": "enh@google.com", "time": "Mon Feb 10 18:22:24 2014 -0800" }, "message": "Switch \u003celf.h\u003e over to linux uapi under the covers.\n\nRemove the linker\u0027s reliance on BSD cruft and use the glibc-style\nElfW macro.
