9de0736973 perf cs-etm: Fix corrupt inject files when only last branch option is enabled 
'perf inject' with Coresight data generates files that cannot be opened
when only the last branch option is specified:

  perf inject -i perf.data --itrace=l -o inject.data
  perf script -i inject.data
  0x33faa8 [0x8]: failed to process type: 9 [Bad address]

This is because cs_etm__synth_instruction_sample() is called even when
the sample type for instructions hasn't been setup. Last branch records
are attached to instruction samples so it doesn't make sense to generate
them when --itrace=i isn't specified anyway.

This change disables all calls of cs_etm__synth_instruction_sample()
unless --itrace=i is specified, resulting in a file with no samples if
only --itrace=l is provided, rather than a bad file.

0b31ea6613 perf cs-etm: No-op refactor of synth opt usage 
sample_branches and sample_instructions are already saved in the
synth_opts struct. Other usages like synth_opts.last_branch don't save a
value, so make this more consistent by always going through synth_opts
and not saving duplicate values.

de9f498d2b perf trace: Avoid early exit due SIGCHLD from non-workload processes 
The function trace__symbols_init() runs "perf-read-vdso32" and that ends up
with a SIGCHLD delivered to 'perf'. And this SIGCHLD make perf exit early.

'perf trace' should exit only if the SIGCHLD is from our workload process.
So let's use sigaction() instead of signal() to match such condition.

Committer notes:

Use memset to zero the 'struct sigaction' variable as the '= { 0 }'
method isn't accepted in many compiler versions, e.g.:

052747700e perf report: Add "addr_from" and "addr_to" sort dimensions 
With the existing symbol_from/symbol_to, branches captured in the same
function would be collapsed into a single function if the latencies
associated with the each branch (cycles) were all the same.  That is the
case on Intel Broadwell, for instance. Since Intel Skylake, the latency
is captured by hardware and therefore is used to disambiguate branches.

Add addr_from/addr_to sort dimensions to sort branches based on their
addresses and not the function there are in. The output is still the
function name but the offset within the function is provided to uniquely
identify each branch.  These new sort dimensions also help with annotate
because they create different entries in the histogram which, in turn,
generates proper branch annotations.

Here is an example using AMD's branch sampling:

  $ perf record -a -b -c 1000037 -e cpu/branch-brs/ test_prg

87a73bdc42 perf test: Make metric testing more robust 
When testing metric expressions we fake counter values from 1 going
upward. For some metrics this can yield negative values that are clipped
to zero, and then cause divide by zero failures.

Such clipping is questionable but may be a result of tools automatically
generating metrics. A workaround for this case is to try a second time
with counter values going in the opposite direction.

This case was seen in a metric like:
  event1 / max(event2 - event3, 0)
But it may also happen in more sensible metrics like:
  event1 / (event2 + event3 - 1 - event4)

1006c5c169 perf c2c: Replace bitmap_weight() with bitmap_empty() where appropriate 
Some code in builtin-c2c.c calls bitmap_weight() to check if any bit of
a given bitmap is set.

It's better to use bitmap_empty() in that case because bitmap_empty()
stops traversing the bitmap as soon as it finds first set bit, while
bitmap_weight() counts all bits unconditionally.

Currently, the transaction flag (x) is kept separate from branch flags.
Instead of doing the same for the interrupt disabled flags (D and t), add
all flags so that new flags will not need to be handled separately in the
future.

Define 2 new flags to represent:

 - when interrupts are disabled (D)
 - when interrupt disabling toggles (t)

This gives 4 combinations:
		no flag, interrupts enabled
	t	interrupts were enabled but become disabled
	D	interrupts are disabled
	Dt	interrupts were disabled but become enabled

Committer notes:

Those are control flow flags, as per 'tools/perf/Documentation/perf-intel-pt.txt:

<quote>
An interesting field that is not printed by default is 'flags' which can be
displayed as follows:

        perf script --itrace=ibxwpe -F+flags

The flags are "bcrosyiABExgh" which stand for branch, call, return, conditional,
system, asynchronous, interrupt, transaction abort, trace begin, trace end,
in transaction, VM-entry, and VM-exit respectively.

Previously, the MODE.Exec packet did not generate any events, so the

As of Intel SDM (https://www.intel.com/sdm) version 076, there is a new
Intel PT feature called Event Trace which requires 2 new packets CFE
(Control Flow Event) and EVD (Event Data).

Each Event Trace event is represented by a CFE packet that is preceded
by zero or more EVD packets. It may be bound to a following FUP (Flow
Update) packet that provides the IP.

Event Trace exposes details about asynchronous events. The CFE packet
contains a type field to identify one of the following:

	 1	INTR		interrupt, fault, exception, NMI
	 2	IRET		interrupt return
	 3	SMI		system management interrupt
	 4	RSM		resume from system management mode
	 5	SIPI		startup interprocessor interrupt
	 6	INIT		INIT signal
	 7	VMENTRY		VM-Entry
	 8	VMEXIT		VM-Entry
	 9	VMEXIT_INTR	VM-Exit due to interrupt
	10	SHUTDOWN	Shutdown

For more details, refer to the Intel SDM, Intel Processor Trace chapter.

Add processing to the decoder for the new packets.

And these new packets are described in page 3951:

<quote>
32.2.4

Event Trace is a capability that exposes details about the asynchronous
events, when they are generated, and when their corresponding software
event handler completes execution. These include:

o Interrupts, including NMI and SMI, including the interrupt vector when
defined.

o Faults, exceptions including the fault vector.

— Page faults additionally include the page fault address, when in context.

o Event handler returns, including IRET and RSM.

o VM exits and VM entries.¹

— VM exits include the values written to the “exit reason” and “exit qualification” VMCS fields.
INIT and SIPI events.

o TSX aborts, including the abort status returned for the RTM instructions.

o Shutdown.

Additionally, it provides indication of the status of the Interrupt Flag
(IF), to indicate when interrupts are masked.

5c8166419a kbuild: replace $(if A,A,B) with $(or A,B) 
$(or ...) is available since GNU Make 3.81, and useful to shorten the
code in some places.

Covert as follows:

  $(if A,A,B)  -->  $(or A,B)

This patch also converts:

  $(if A, A, B) --> $(or A, B)

Strictly speaking, the latter is not an equivalent conversion because
GNU Make keeps spaces after commas; if A is not empty, $(if A, A, B)
expands to " A", while $(or A, B) expands to "A".

Anyway, preceding spaces are not significant in the code hunks I touched.
