2013-11-12 Rong Xu <xur@google.com> The patch re-factors libgcov.c to make it better modulelized. It contains two pieces of work: 1. break gcov_exit() into the following structure: gcov_exit() --> gcov_exit_compute_summary() --> allocate_filename_struct() for gi_ptr in gcov_list --> gcov_exit_dump_gcov() --> gcov_exit_open_gcda_file() --> gcov_exit_merge_gcda () --> gcov_exit_merge_summary () --> gcov_exit_write_gcda () 2. split libgcov.c into the following files: libgcov-profiler.c libgcov-merge.c libgcov-interface.c libgcov-driver.c libgcov-driver-system.c (source included into libgcov-driver.c) * libgcc/libgcov.c: Delete as part of re-factoring. * gcc/gcov-io.h (__gcov_indirect_call_profiler): Add the decl to avoid warning. * libgcc/libgcov-interface.c (init_mx): Moved from libgcov.c.
