Support traceview-style profiling in all builds
This change builds on an earlier bccheng change that allowed JIT'd code
to avoid reverting to the debug portable interpeter when doing traceview-style
method profiling. That CL introduced a new traceview build (libdvm_traceview)
because the performance delta was too great to enable the capability for
all builds.
In this CL, we remove the libdvm_traceview build and provide full-speed
method tracing in all builds. This is done by introducing "_PROF"
versions of invoke and return templates used by the JIT. Normally, these
templates are not used, and performace in unaffected. However, when method
profiling is enabled, all existing translation are purged and new translations
are created using the _PROF templates. These templates introduce a
smallish performance penalty above and beyond the actual tracing cost, but
again are only used when tracing has been enabled.
Strictly speaking, there is a slight burden that is placed on invokes and
returns in the non-tracing case - on the order of an additional 3 or 4
cycles per invoke/return. Those operations are already heavyweight enough
that I was unable to measure the added cost in benchmarks.

Merge "Consolidate mterp's debug/profile/suspend control" into dalvik-dev
buzbee [Fri, 14 Jan 2011 21:37:31 +0000 (13:37 -0800)]
Consolidate mterp's debug/profile/suspend control
This is a step towards full debug & profiling support in JIT'd code.
Previously, the interpreter made multiple distinct checks for pending
suspend requests, debugger and profiler checks at each safe point.
This CL moves the individual controls into a single control word,
significantly speeding up the safe-point check code path in the common
fast case.
In short, any time some VM component wants control to break at a safe
point it will set a bit in gDvm.interpBreak, which will be examined
at the safe point check in footer.S. In the old code, the safe point
check consisted of 11 instructions (including 6 loads). The new sequence
is 6 instructions (4 loads - two of which are needed and two are
speculative to fill otherwise stalling slots).
This code path is hot enough in the interpreter that we actually see
some measureable speedups in benchmarks. The old sieve benchmark
improves from 252 to 256 (~1.5%).
As part of the change, global debuggerActive and activeProfilers variables
have been eliminated as redundant. Note also that there is a subtle
change in thread suspension. Thread suspend request counts are kept on
a per-thread basis, and previously each thread would only examine its own
suspend count. With this change, a bit has been allocated in interpBreak
to signify that at least one suspend request is active across all
threads. This bit is treated as "some thread is supposed to
suspend, check to see if it's me".

Implement growth limits to support multiple heap configurations.
When a growth limit is in effect, allocations will be limited to
number of bytes specified by the growth limit instead of the maximum
heap size. Growth limits are specified on the command line with the
new parameter -XX:HeapGrowthLimit. A growth limit can be removed at
runtime by calling the new clearGrowthLimit method.
This is a work around until we can adjust the maximum heap size at
runtime.

Optimized dx instruction expansion to only generate necessary moves.
When an instruction's fields do not fit into an instruction format, dx
expands the instruction. Before, this would always use new registers for
sources and destination, generating moves for each. However, some of
these moves would be unnecessary if an original register already fit
into the instruction format. This change checks to see if the original
register fits before using a new register and generating a new move.

This change removes the "dvm" prefix from static functions and makes
the memory option processor use the potentially wider size_t type for
manipulating memory sizes instead of the unsigned int type.

Fix implementation of volatile stores
Volatile stores are synchronization actions, not merely releasing
stores, so an additional barrier is required. We also have the
option of using atomic operations, but that's not recommended (except
for 64-bit fields, where we don't have a choice).

Handle the case of referent clearing during tracing.
Reference objects with non-null referent fields are collected during
tracing for processing after the trace has completed. Before the
trace was made concurrent there was no way for a reference with a
non-null referent field to have its referent become null by any action
of the garbage collector after it was discovered. Assertions were
placed in the reference processing code to check this invariant.
After the trace was made concurrent it became possible for a user to
clear the referent field of an already discovered reference. This
violates the assertions in the reference processing code.
This change replaces the assertions in the reference processing code
with logic to deal with null referent fields. The assert in the
SoftReference preservation code has been converted to a continue that
short circuits the preservation logic. The assert in the white
reference clearing code short circuits the clearing and enqueueing.
