  "message": "Minor cleanups.\n\n1. Further BLAS and heap allocation cleanups in  schur_eliminator_impl.h\n2. Modularize blas.h using macros.\n3. Lint cleanups from William Rucklidge.\n4. Small changes to jet.h\n5. ResidualBlock now uses blas.h\n\nPerformance improvements:\n\nFor static and dynamic sized blocks, the peformance is not changed much.\n\n-use_quaternions -ordering user -linear_solver sparse_schur\n\n                                        master         change\nproblem: 16-22106\ngcc                                        3.4            3.3\nclang                                      2.8            2.7\n\nproblem: 49-7776\ngcc                                        1.7            1.7\nclang                                      1.4            1.4\n\nproblem: 245-198739\ngcc                                       80.1           79.6\nclang                                     80.6           76.2\n\nproblem: 257-65132\ngcc                                       12.2           12.0\nclang                                     10.4           10.2\n\nproblem: 356-226730\ngcc                                       99.0           96.8\nclang                                     88.9           88.3\n\nproblem: 744-543562\ngcc                                      361.5          356.2\nclang                                    352.7          343.5\n\nproblem: 1024-110968\ngcc                                       45.9           45.6\nclang                                     42.6           42.1\n\nHowever, performance when using local parameterizations is\nsignificantly improved due to residual_block.cc using blas.h\n\n-use_quaternions -use_local_parameterization -ordering user -linear_solver sparse_schur\n\n                                        master         change\nproblem: 16-22106\ngcc                                        3.6            3.3\nclang                                      3.5            2.8\n\nproblem: 49-7776\ngcc                                        1.8            1.6\nclang                                      1.7            1.4\n\nproblem: 245-198739\ngcc                                       79.7           76.1\nclang                                     79.7           73.0\n\nproblem: 257-65132\ngcc                                       12.8           11.9\nclang                                     12.3            9.8\n\nproblem: 356-226730\ngcc                                      101.9           93.5\nclang                                    105.0           86.8\n\nproblem: 744-543562\ngcc                                      367.9          350.5\nclang                                    355.3          323.1\n\nproblem: 1024-110968\ngcc                                       43.0           40.3\nclang                                     41.0           37.5\n\nChange-Id: I6dcf7476ddaa77cb116558d112a9cf1e832f5fc9\n",
