Some content in Makefile.in is removed because after this change, the
scripts no longer invoke the preprocessor and thus don't have unknown
dependencies anymore outside what is provided in their inputs array.
The order of exports.PREFERENCES in properties-db changes because the
data file has shorthands placed after longhands. The only usage of it
is in test_css-properties-db.js which doesn't care about the order.

This patch contains the meat of the changes here. The following summarize the changes:
1. xptinfo.h is rewritten to expose the new interface for reading the XPT data,
The nsXPTInterfaceInfo object exposes methods with the same signatures as
the methods on nsIInterfaceInfo, to make converting code which used
nsIInterfaceInfo as easy as possible, even when those methods don't have
signatures which make a ton of sense anymore. There are also a few methods
which are unnecessary (they return `true` or similar), which should be
removed over time.
Members of the data structures are made private in order to prevent reading
them directly. Code should instead call the getter methods. This should make
it easier to change their memory representation in the future. Constructing
these structs is made possible by making the structs `friend class` with the
XPTConstruct class, which is implemented by the code generator, and is able
to access the private fields.
In addition, rather than using integers with flag constants, I opted for
using C++ bitfields to store individual flags, as I found it made it easier
to both write the code generator, and reason about the layouts of the types.
I was able to shave a byte off of each nsXPTParamInfo (4 bytes -> 3 bytes)
by shoving the flags into spare bits in the nsXPTType. Unfortunately there
was not enough room for the retval flag. Fortunately, we already depend in
our code on the retval parameter being the last parameter, so I worked
around this by removing the retval flag and instead having a `hasretval`
flag on the method itself.
2. An xptinfo.cpp file is added for out-of-line definitions of more complex
methods, and the internal implementation details of the perfect hash.
Notable is the handling of xptshim interfaces. As the type is uniform, a
flag is checked when trying to read constant information, and a different
table with pointers into webidl data structures is checked when the type is
determined to be a shim.
Ideally we could remove this once we remove the remaining consumers of the
existing shim interfaces.
3. A python code generator which takes in the json XPT files generated in the
previous part, and emits a xptdata.cpp file with the data structures. I did
my best to heavily comment the code.
This code uses the friend class trick to construct the private fields of the
structs, and avoid a dependency on the ordering of fields in xptinfo.h.
The sInterfaces array's order is determined by a generated perfect hash
which is also written into the binary. This should allow for fast lookups by
IID or name of interfaces in memory. The hash function used for the perfect
hash is a simple FNV hash, as they're pretty fast.
For perfect hashing of names, another table is created which contains
indexes into the sInterfaces table. Lookup by name is less common, and this
form of lookup should still be very fast.
4. The necessary Makefiles are updated to use the new code generator, and
generate the file correctly.
The uninstaller was being built as a side-effect of building `setup.exe`. In
Bug 1385227, that was moved from "somewhere" to part of the windows installer
packaging, which happens after the zip and mar are generated. Since the
installer we ship is actually repackaged from the zip[1], we stopped shipping
translated uninstallers.
This changes things around so that the uninstaller gets translated:
- Explicitly build the uninstaller as part of the L10n repack step.
- Use the same logic to build the installer locally as we do to create the ones
we ship.

This patch is a nearly complete reimplementation of BinASTReader, with the following changes:
- Files BinToken.h, BinSource-auto.h (new), BinSource-auto.cpp (new) are now autogenerated by the generator in js/src/frontend/binsouce from the webidl specifications of BinAST and a small
configuration file.
- Optional fields have been removed. Rather, some specific fields may, if so marked in the specifications, contain a Null constant.
- `hasDirectEval` is now checked for consistency (NOT completeness).
- `varDeclaredNames` is now checked for consistency (NOT completeness).
- `lexicallyDeclaredNames` is now checked for consistency (NOT completeness).
- `parameterNames` is now checked for consistency (NOT completeness).
- `capturedNames` is NOT checked.
- Atoms read are now properly expected to be UTF8.
This patch does not implement the entire specifications, but should implement most of ES5. In particular, it is sufficient to parse the source code of:
- Facebook;
- jQuery;
- mootools;
- Underscore;
- Backbone;
- Angular.

This patch handles the actual generation of the static data structures
used to represent XPT information. XPT files are generated in the same
way as they are now, but they are used only as an intermediate
representation to speed up incremental compilation rather than
something used by Firefox itself. Instead of linking XPTs into a
single big XPT file at packaging time, they are linked into a single
big C++ file at build time, that defines the various static consts in
XPTHeader.
In xpt.py, every data structure that can get written to disk gets an
additional code_gen() method that returns a representation of that
data structure as C++ source code. CodeGenData aggregates this
information together, handling deduplication and the final source code
generation.
The ctors are needed for XPTConstValue to statically initialize the
different union cases without resorting to designated initializers,
which are part of C99, not C++. Designated initializers appear to be
supported in C++ code by Clang and GCC, but not MSVC. The ctors must
be constexpr to ensure they are actually statically initialized so
they can be shared between Firefox processes.
I also removed an unnecessary "union" in XPTConstDescriptor.
Together, these patches reduce the amount of memory reported by
xpti-working-set from about 860,000 bytes to about 200,000 bytes. The
remaining memory is used for xptiInterface and xptiTypelibGuts (which
are thin wrappers around the XPT interfaces and header) and hash
tables to speed up looking up interfaces by name or IID. That could
potentially be eliminated from dynamic allocations in follow up
work. These patches did not affect memory reporting because XPT arenas
are still used by the remaining XPTI data structures.

Now that XPT files are not loaded from files at runtime, code for
packaging XPT files can be removed.
This means that a couple of test XPIDL interfaces will get shipped in
builds to users that weren't before, but I don't think that matters
much.
This also puts XPT files into the local objdir for the XPIDL makefile,
instead of dist/bin, because they are no longer part of the
distribution.

The MSVC linker winds up generating import libraries when linking some of
our executables, presumably because they contain functions that are
__declspec(dllexport). By default the import libraries get written
alongside the exe, so we force them to be written to the objdir so they don't
clutter up dist/bin.

Historically we built all our binaries in directories in the objdir, then
symlinked them into dist/bin. Some binaries needed to be copied instead
so that certain relative path lookups work properly, so we resorted to
sprinkling `NSDISTMODE=copy` around Makefiles.
This change makes it so we build PROGRAMs (not any other sort of targets)
directly in dist/bin instead. We could do the same for our other targets
with a little more work.
There were several places in the tree that were copying built binaries to
some other place and needed fixup to match the new location of binaries.
On Windows pdb files are left in the objdir where the program was
originally linked. symbolstore.py needs to locate the pdb file both to
determine whether it should dump symbols for a binary and also to copy
the pdb file into the symbol package. We fix this by simply looking for
the pdb file in the current working directory if it isn't present next
to the binary, which matches how we invoke symbolstore.py.

We use a wrapper script when compiling with MSVC to parse the
/showIncludes output and thereby generate a Makefile dependency
fragment. This fragment enables us to do correct and faster incremental
builds. But the cost of invoking the wrapper script can be significant;
it's an extra process or two to launch for every single compilation.
Instead, let's have clang-cl generate the dependencies directly, which
should be somewhat faster.
There are a lot of choices and moving pieces in this commit. I elected
to include the mechanics and the target use case in the same commit so
that readers can compare and contrast the implementation and final
expression in one review window.
- Initially, I wanted to make the {AB_CD} substitutions in
LOCALIZED_FILES and not in LOCALIZED_GENERATED_FILES. However, I ran
into conceptual blockers doing this. Fundamentally, LOCALIZED_FILES
is FINAL_TARGET_FILES, and my use case should _not_ be putting files
anywhere near dist/bin. In addition, LOCALIZED_FILES
(FINAL_TARGET_FILES) is handled using manifests, which would need to
grow locale-aware functionality to handle this. That's not desirable.
In addition, if we use manifests, then we lose the powerful locality
of |mach build mobile/android{/base}| re-generating changed
locale-dependent resources. This is similar to how the build system
plumbs dist/idl manifest processing throughout the build: we're
repairing local workflows after moving work into a global process.
For these reasons, this doesn't support {AB_CD} in LOCALIZED_FILES.
- There is even another layer of complexity! There are two axes
involved with these files: AB_CD controls localization and the Make
target controls destination. For the record, it is:
regular builds - AB_CD unset
multi-locale builds - AB_CD set
single-locale repacks - AB_CD set
For the record, the existing logic (before any changes) is:
regular builds - Make target is `libs` in mobile/android/base/locales
multi-locale builds - Make target is `chrome-%` in mobile/android/base/locales
single-locale repacks - Make target is `libs` in mobile/android/base/locales
This commit adds targets for both destinations, and uses Make
chrome-%:: and libs:: magic to control what is invoked in the various
situations. Tricky!
- I added MERGE_RELATIVE_FILES in order to be able to follow-up this
patch with more patches that will get rid of
m/a/base/locales/{moz.build,Makefile.in} altogether, and fold this work
into m/a/base. As it stands, we're already reaching from
m/a/base/locales all the way out to
mobile/locales/.../region.properties, so the existing code doesn't
follow the layout expected between mozilla-central and
l10n-central/$(AB_CD). But that'll impedance will get worse as we
improve the build system dependencies, not better, so we should grow
support for localized resources that aren't exactly as expected.
- I chose to follow Python's syntax for string substitutions. I
would have preferred to mark files that should be localized with a
leading '%'... but I took that for filesystem absolute paths in
moz.build files already. I also considered @AB_CD@ to echo the
preprocessor, but didn't want to open the door to an expecation that
_all_ preprocessor DEFINEs will work in the way {AB_CD} does.
- The generate_*py script changes required a bit of a hack to "turn
off" locale dependent resources. This would have been nicer if we had
marked localized resources with '%'... but we didn't. See the
--fallback flag. The real reason this is needed is that we're doing
work which is more like the work of compare-locales (merging
locale-dependent resources) at build-time rather than repack time. I
don't know why that's the case -- probably when we (I) implemented it,
compare-locales and the whole l10n process was entirely opaque. It's
not worth changing it now, so we use this --fallback flag approach.
- I didn't get to tup support. This should gently fail without
breaking tup builds: any {AB_CD} substitutions just won't be
expanded. I haven't a clue how this should work in tup in the future
(or, more generally, how to make any sense of repacks without
declaring the full set of expected locales at configure time.)
- strings.xml can't be a LOCALIZED_PP_FILES, since we need to
customize the output location based on AB_rCD, and since we need a
little more flexibility than PP_FILES gives for our inputs.

I wanted to lift this next to the definition of AB_CD, but that
doesn't allow to use it in a backend.mk file, due to the order in
which Makefile, config.mk, rules.mk, and backend.mk are processed.
Therefore, I've put it in a tiny include file, so that it can be used
by a Makefile and a backend.mk file.
This allows the `RecursiveMake` backend to owning defining AB_rCD in
backend.mk files, while not requiring consumers to arrange for AB_rCD
in a sibling Makefile.in file.
Other build backends will need to arrange for AB_rCD themselves: see
following commits.
