      Better GetAvilableLocales check resources · 942f3e11
      Frank Tang authored 
      1. Check resources and not solely depend on res_index.res file
2. Performance is +2-3% for Collator, DateTimeFormat, Locale,
   -2-3% for PluralRules, RelativeTimeFormat, ListFormat, NumberFormat
   Consider we improve the performance x3 not long ago, these perf
   regression could be ignored.

      Reland "Add Crash Keys support" · 5ad5f0ac
      Irina Yatsenko authored 
      This is a reland of 02103b27

Fix for the original build break: build android with noop crashkeys for now

Original change's description:
> Add Crash Keys support
>
> This adds crash keys containing the isolate address and addresses of
> the read_only, map, and code spaces to crash report minidumps.
> When not compiling V8 with Chrome, a noop implementation is used.

      [SFI] Always store function_literal_id in SFI. · f92d7196
      Ross McIlroy authored 
      Calling FindIndexInScript performs a linear search on the script functions and can
take considerable time. With Bytecode flushing we will lose the function_literal_id
and have to call FindIndexInScript if we ever recompile the flushed function. This
can take a significant proportion of the recompilation time and has caused regressions
in rendering times for some web applications (e.g, 395ms in FindIndexInScript for 132ms
spent lazily re-compiling code).

To avoid this, add function_literal_id back into the SFI and remove it from
UnoptimizedCompileInfo. This will slightly regress memory usage (particularly
in cases where many of the SFIs are compiled), however it means we can remove
the FindIndexInScript function and avoid these long-tail regressions when
bytecode is flushed.

      [torque] Support 'real' internal classes · 76c1e829
      Sigurd Schneider authored 
      Rework the implementation of non-external Torque classes to use
Struct machinery rather than FixedArray machinery. This allows
Torque-only defined 'internal' classes to the automatically generate
class verifiers and printers.

As part of this change, generate C++ boilerplate accessors for
internal Torque classes, since this is a pre-requisite for the
verifiers, printers and other Struct-based functionality.

Moreover, augment the header-generating functionality in Torque
to create separate header files for field offset definitions,
internal class C++ definitions and instance types.

      Added !mem and !where extensions to windbg.js · 4965a34e
      Irina Yatsenko authored 
      The extensions require isolate address to be set but don't rely on calling
any runtime functions, which makes them viable for post-mortem debugging,
if the corresponding memory is included into the dump

!set_iso(isolate_address)
    call this function before using !mem or other heap routines

!mem or !mem(\"space1[ space2 ...]\")
    prints memory chunks from the 'space' owned by the heap in the
    isolate set by !set_iso; valid values for 'space' are:
    new, old, map, code, lo [large], nlo [newlarge], ro [readonly]
    if no 'space' specified prints memory chunks for all spaces,
    e.g. !mem(\"code\"), !mem(\"ro new old\")

!where(address)
    prints name of the space and address of the MemoryChunk the
    'address' is from, e.g. !where(0x235cb869f9)


Output from !mem would look something like this:

0:000> !mem("old")
Heap at 0x210652b8838
Im   address:	 object area start - end (size)
OldSpace (allocating at: 0x1703dae7a20):
*    0x33d9a8c0000:	 0x33d9a8c0138 - 0x33d9a8f1000 (0x31000)
     0x1703dac0000:	 0x1703dac0138 - 0x1703db00000 (0x40000)

      [wasm] Support table.copy for anyref tables · 21719af9
      Andreas Haas authored 
      The table.copy instruction used the indirect_function_table_size field
of the instance for bounds-checks. However, when Table 0 is of type
anyref, this field is not set. Now we use the actual size of the table
instead.
