When analyzing perf data from hosts of other architecture than one of the local host it's useful to call objdump that is part of a toolchain for that architecture. Instead of calling regular objdump, call one that user specified in command line.

A large enough symbol size causes an overflow in the size parameter to the histogram allocation, leading to a segfault in symbol__inc_addr_samples later on when this histogram is accessed. In the case of being called via perf-report, this returns back and gracefully ignores the sample, eventually ignoring the chained return value of perf_session_deliver_event in flush_sample_queue.

This routine was checking only if the provided address was after sym->end, not if it was before sym->start. Fix that by checking for both and return in both cases -ERANGE, so that tools can communicate this to the user properly, or if they chose so, to abort. This problem was reported previously but the fixes involved either doing what was being done for the > end case, i.e. silently drop the sample, returning 0, or aborting at this function, which is in a lib (or better, is slated to be at some point) and shouldn't abort. The 'report' tool already checks this value and uses pr_debug to warn the user. This patch makes the 'top' tool check it too and warn once per map where such range problem takes place.

I get such truncated annotation results in 'perf top': : Disassembly of section .text: ▒ : ▒ : ffffffff810966a8 <nr_iowait_cpu>: ▒ 4.94 : ffffffff810966a8: movslq %edi,%rdi ▒ 3.70 : ffffffff810966ab: mov $0x13700,%rax ▒ 0.00 : ffffffff810966b2: add -0x7e32cb00(,%rdi,8),%rax ▒ 8.64 : ffffffff810966ba: mov 0x7e0(%rax),%eax ▒ 82.72 : ffffffff810966c0: cltq ▒ Note the missing 'retq' which is there in the original function: ffffffff810966a8 <nr_iowait_cpu>: ffffffff810966a8: 48 63 ff movslq %edi,%rdi ffffffff810966ab: 48 c7 c0 00 37 01 00 mov $0x13700,%rax ffffffff810966b2: 48 03 04 fd 00 35 cd add -0x7e32cb00(,%rdi,8),%rax ffffffff810966b9: 81 ffffffff810966ba: 8b 80 e0 07 00 00 mov 0x7e0(%rax),%eax ffffffff810966c0: 48 98 cltq ffffffff810966c2: c3 retq ffffffff810966c3 <this_cpu_load>: I'm using a fairly recent binutils: GNU objdump version 2.21.51.0.6-2.fc16 20110118 AFAICS the bug is simply that sym->end points to the last byte of the symbol in question - while objdump's --stop-address expects the last byte plus 1 to disassemble the full range.

Since symbol__alloc_hists need it, to avoid passing it around in many functions have it in the symbol_conf struct.

Add -M option to report/annotate to pass directly to objdump. This allows to use -M intel for intel style disassembler syntax, which is useful for people who are very used to the Intel syntax.

This patch adds two new options to perf annotate: - --no-asm-raw : Do not display raw instruction encodings - --no-source : Do not interleave source code with assembly code We believe those options make the output of annotate more readable. Systematically displaying source can make it hard to follow code and especially optimized code. Raw encodings are not useful in most cases.

In both --tui and --stdio, in 'annotate', 'top', 'report' when trying to annotate a kernel symbol having just access to a kallsyms file, that doesn't have the DWARF info needed for annotation.

The live annotation done in 'perf top' needs to limit the context before lines that aren't filtered out by the min percent filter, if we don't do that, the screen in a tty often is not enough for showing what is interesting: lines with hits and a few source code lines before it.

Since we'll need it when implementing the live annotate TUI browser. This also simplifies things a bit by having the list head for the source code to be in the dynamicly allocated part of struct annotation, that way we don't have to pass it around, it can be found from the struct symbol that is passed everywhere.
