* Use clamping to more easily normalize input valuesJosh Stone2010-02-161-6/+6
| | | | | | The kernel has min/max/clamp macros to make range comparisons easier. Clamp is a newer invention, but we can define it for older kernels in terms of min and max.
* Cleanup and better original transport support.David Smith2009-05-261-3/+1
| | | | | | | | | | * runtime/print.h: Moved _stp_reserve_bytes() prototype here. * runtime/vsprintf.c (_stp_vsnprintf): Includes print.h to get _stp_reserve_bytes() prototype. * runtime/transport/transport.c (_stp_remove_root_dir): Better cleanup for STP_TRANSPORT_VERSION == 1. (_stp_transport_fs_close): Ditto.
* Added error checking and other updates.David Smith2009-05-221-0/+2
| | | | | | | | | | | | | | | | | | * runtime/vsprintf.c: Added transport.h inclusion for STP_BUFFER_SIZE definition. * runtime/transport/debugfs.c (_stp_register_ctl_channel_fs): Added error checking. * runtime/transport/transport.c (_stp_get_root_dir): Ditto. (_stp_transport_fs_init): Added original transport support and error checking. * runtime/transport/relay_v2.c (__stp_relay_create_buf_file_callback): Added error checking. (_stp_transport_data_fs_init): Ditto. * runtime/transport/ring_buffer.c (_stp_transport_data_fs_init): Ditto. * runtime/transport/utt.c: Removed unused file. * runtime/transport/utt.h: Ditto.
* PR10099: Extend %M directive to support hexdumping large buffersWenji Huang2009-04-261-12/+19
| | | | | | | | | | This patch will make %M directive dump the variable width buffer in hex format instead of returning uint64_t number as before. * runtime/vsprintf.c: Modify %M directive. * stap.1.in: Update description. * testsuite/systemtap.printf/memory1.stp: Add test case.

* Use 'static' as much as possibleJosh Stone2009-01-281-1/+1
| | | | | | | | | | 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.
