This is an attempt to bring support for modified gcov format in gcc 4.7 to the kernel. It tries to leverage the existing layout/abstraction, which was designed keeping in mind that the gcov format could change, but some changes had to be make. Mostly because the current model does not take into account that even the core gcov structures, like gcov_info, could change. One part that could be problematic is the addition of the .init_array section for constructors.
Tested with lcov and seems to be working fine, giving similar results as for the older format.
Frantisek Hrbata (4): gcov: move gcov structs definitions to a gcc version specific file gcov: add support for gcc 4.7 gcov format gcov: compile specific gcov implementation based on gcc version kernel: add support for init_array constructors
