When debugging the tui browser I find it useful to redirect the debug log into a file. Currently it's always forced to the message line. Add an option to force it to stderr.

We need to define bfd_demangle() to either a wrapper for cplus_demangle() or to a stub when NO_DEMANGLE is defined. That is at odds with using bfd.h for some other reason, as it defines bfd_demangle() and then if code that wants to use symbol.h, where the above stubbing/wrapping is done, and bfd.h for other reasons, we end up with a build error where bfd_demangle() is found to be redefined. Avoid that by moving the stubbing/wrapping to symbol-elf.c, that is the only user of such function. If we ever get to a point where there are more valid users, we can then introduce a header for that.

For lbr-as-callgraph we need to see the line number in the history, because many LBR entries can be in a single function, and just showing the same function name many times is not useful. When the history code is configured to sort by address, also try to resolve the address to a file:srcline and display this in the browser. If that doesn't work still display the address. This can be also useful without LBRs for understanding which call in a large function (or in which inlined function) called something else.

Currently perf report on TUI doesn't print percent for first-level callchain entry. I guess it (wrongly) assumes that there's only a single callchain in the first level. This patch fixes it by handling the first level callchains same as others - if it's not 100% it should print the percent value. Also it'll affect other callchains in the other way around - if it's 100% (single callchain) it should not print the percentage.

Events may still be ordered even if there are no timestamps e.g. if the data is recorded per-thread. Also synthesized COMM events have a timestamp of zero. Consequently it is better to keep comm entries even if they have a timestamp of zero. However, when a struct thread is created the command string is not known and a comm entry with a string of the form ":<tid>" is used. In that case thread->comm_set is false and the comm entry should be overridden.

With srcline key/sort'ing it's useful to have line numbers in the annotate window. This patch implements this. Use objdump -l to request the line numbers and save them in the line structure. Then the browser displays them for source lines. The line numbers are not displayed by default, but can be toggled on with 'k' There is one unfortunate problem with this setup. For lines not containing source and which are outside functions objdump -l reports line numbers off by a few: it always reports the first line number in the next function even for lines that are outside the function. I haven't found a nice way to detect/correct this. Probably objdump has to be fixed. See https://sourceware.org/bugzilla/show_bug.cgi?id=16433 The line numbers are still useful even with these problems, as most are correct and the ones which are not are nearby. v2: Fix help text. Handle (discriminator...) output in objdump. Left align the line numbers.

The minimal ELF loader should not return 1 when it manages to read the vmlinux build-id, it should instead return 0, meaning that it hasn't loaded any symbols, since it doesn't parses ELF at all. That way, the main symbol.c routines will understand that it is necessary to continue looking for a file with symbols, and when no libelf is linked, that means it will eventually try kallsyms.

Current EXTLIBS contains -lelf by default and removes it when libelf is not detected. This is little bit confusing since we can now build perf without libelf so there's no need to handle it differently than other libraries.

PEBS can capture machine state regs at retiremnt of the sampled instructions. When precise sampling is enabled on an event, PEBS is used, so substitute the interrupted state with the PEBS state. Note that not all registers are captured by PEBS. Those missing are replaced by the interrupt state counter-parts.

Enable capture of interrupted machine state for each sample. Registers to sample are passed per event in the sample_regs_intr bitmask. To sample interrupt machine state, the PERF_SAMPLE_INTR_REGS must be passed in sample_type. The list of available registers is arch dependent and provided by asm/perf_regs.h Registers are laid out as u64 in the order of the bit order of sample_intr_regs. This patch also adds a new ABI version PERF_ATTR_SIZE_VER4 because we extend the perf_event_attr struct with a new u64 field.

Disallow setting inv/cmask/etc. flags for all PEBS events on these CPUs, except for the UOPS_RETIRED.* events on Nehalem/Westmere, which are needed for cycles:p. This avoids an undefined situation strongly discouraged by the Intle SDM. The PLD_* events were already covered. This follows the earlier changes for Sandy Bridge and alter.

My earlier commit: 86a04461 ("perf/x86: Revamp PEBS event selection") made nearly all PEBS on Sandy/IvyBridge/Haswell to reject non zero flags. However this wasn't done for the INST_RETIRED.PREC_DIST event because no suitable macro existed. Now that we have INTEL_FLAGS_UEVENT_CONSTRAINT enforce zero flags for INST_RETIRED.PREC_DIST too.
