perf_counter tools: Define and use our own u64, s64 etc. definitions On 64-bit powerpc, __u64 is defined to be unsigned long rather than unsigned long long. This causes compiler warnings every time we print a __u64 value with %Lx. Rather than changing __u64, we define our own u64 to be unsigned long long on all architectures, and similarly s64 as signed long long. For consistency we also define u32, s32, u16, s16, u8 and s8. These definitions are put in a new header, types.h, because these definitions are needed in util/string.h and util/symbol.h. The main change here is the mechanical change of __[us]{64,32,16,8} to remove the "__". The other changes are: * Create types.h * Include types.h in perf.h, util/string.h and util/symbol.h * Add types.h to the LIB_H definition in Makefile * Added (u64) casts in process_overflow_event() and print_sym_table() to kill two remaining warnings.

perf tools: Add new perf_atoll() function to parse string representing size in bytes This patch modifies util/string.[ch] to add new function: perf_atoll() to parse string representing size in bytes. This function parses (\d+)(b|B|kb|KB|mb|MB|gb|GB) (e.g. "256MB") and returns its numeric value.

perf probe: Add lazy line matching support Add lazy line matching support for specifying new probes. This also changes the syntax of perf probe a bit. Now perf probe accepts one of below probe event definitions. 1) Define event based on function name [EVENT=]FUNC[@SRC][:RLN|+OFF|%return|;PTN] [ARG ...] 2) Define event based on source file with line number [EVENT=]SRC:ALN [ARG ...] 3) Define event based on source file with lazy pattern [EVENT=]SRC;PTN [ARG ...] - New lazy matching pattern(PTN) follows ';' (semicolon). And it must be put the end of the definition. - So, @SRC is no longer the part which must be put at the end of the definition. Note that ';' (semicolon) can be interpreted as the end of a command by the shell. This means that you need to quote it. (anyway you will need to quote the lazy pattern itself too, because it may contains other sensitive characters, like '[',']' etc.). Lazy matching ------------- The lazy line matching is similar to glob matching except ignoring spaces in both of pattern and target. e.g. 'a=*' can matches 'a=b', 'a = b', 'a == b' and so on. This provides some sort of flexibility and robustness to probe point definitions against minor code changes. (for example, actual 10th line of schedule() can be changed easily by modifying schedule(), but the same line matching 'rq=cpu_rq*' may still exist.) Changes in v3: - Cast Dwarf_Addr to uintmax_t for printf-formats. Changes in v2: - Cast Dwarf_Addr to unsigned long long for printf-formats.
