* Removed unused functions and variables.David Smith2009-02-181-34/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | 2009-02-18 David Smith <dsmith@redhat.com> * io.c (_stp_log): Removed unused function. * map.c (_stp_cmp): Replace _stp_log() with dbug(). * mempool.c (_stp_mempool_resize): Removed unused function. * print.c (next_fmt): Removed unused function. * procfs.c: Removed unused variable '_stp_num_procfs_files'. * regs.c (_stp_ret_addr): Removed unused function. * string.c (_stp_text_str): Removed unused variable 'len'. * string.h: Removed unused variable '_stdout_' and function declaration for deleted function '_stp_vsprintf'. * sym.c: Removed unused variables. * unwind.c (_stp_create_unwind_hdr): Removed unused function. 2009-02-18 David Smith <dsmith@redhat.com> * control.c: Removed unused variable '_stp_current_buffers'. * procfs.c (_stp_set_buffers): Removed unused function. (_stp_register_ctl_channel_fs): Removed unused variables and label. * symbols.c (u32_swap): Removed unused function. (generic_swap): Ditto. (_stp_sort): Ditto.

* Use 'static' as much as possibleJosh Stone2009-01-281-8/+8
| | | | | | | | | | This change just inserts 'static' on runtime, tapset, and generated C functions and globals, so the compiler can do a better job of optimizing. My tests with small scripts show ~10% reduction in compile time and ~20% reduction in module size. Larger scripts may show less benefit, but I expect purely positive results.
