c1f2da0e0b Improve the performance of the TypeRewriter.rewrite method 2020-02-03 00:09:21 -08:00
Ben Gruver
409cf27ba9 Make the new TypeRewriter.rewriteUnwrappedType protected 
This method shouldn't be called from outside the class.

12b95235e3 Add a dex file rewriter to the rewriters module 
Previously, if you needed to provide a custom dex file rewriter, you
would have to override the DexRewriter class. This provides a more
consistent interface, allowing the dex file rewriter to be specified in
the module.

78e92b0524 Add support for automatically rewriting array types in the rewriter 
This adds a new rewriteUnwrappedType to the TypeRewriter class, which
gets called with the unwrapped type for array types, with the potentially
modified return value automatically being re-array-ified.

5a900e22e0 Use reference type from wrapped instruction in BaseRewrittenReferenceInstruction 
Otherwise, the reference won't be rewritten correctly if the overriding
class overrides getReferenceType to return a different type.

49f7e26507 Set the hiddenApiRestrictionOffset in the new DexBackedDexFile constructor 
This fixes the build. That's what I get for rebasing changes and not
testing.

b3b8778ef8 Add support for Oat versions up to 173 
The only relevant differences are some added/removed fields in the
OatHeader that affect the offsets of some fields we use.

1ac14a1082 Add a workaround for the sym linked vdex files in api 28 
In api 28, the vdex files in, e.g. the framework/arm directory are actually
just sym links to a shared vdex file in the framework directory. However,
the sym links use an absolute path, and so they don't resolve correctly in
the loop mounted system image.

As a simple workaround, we'll just search upward one directory in the path
if the vdex file can't be resolved.

c639d229c6 Add support for the new debug offset table for cdex files 2019-08-07 14:12:19 -07:00

8e4391262d Some dex files are listed in the oat file, but aren't present in the oat/vdex 
Oat version 138 introduced the concept of an "uncompressed" dex file, where
the dex file is listed in the oat file, but it's not actually present in
the oat or vdex files, instead, it's in the apk as per usual.

This change makes dexlib2 ignore these files, treating them as if they are
not a part of the oat file.

6c110c1d96 Allow '!' as a separator char in embedded dex file names 
Newer versions of art seem to use ! instead of : to separate the
inner dex filename from the name of the container containing it.

e.g.
/system/framework/framework.jar!classes2.dex
instead of
/system/framework/framework.jar:classes2.dex

732fe07403 Add initial support for cdex files 
Loading cdex files is mostly supported, except for the new debug info
structures.

Dumping is somewhat supported, but only when there's a single cdex file
in the vdex.

eb3ab41fb1 Refactor CodeItem in preparation for cdex implementation

862c767d58 Let a section override how it calculates the item offsets 
This will be needed for the cdex code_item section, whose format doesn't
allow direct enumeration like we use for everything else.

Ben Gruver
587efc71dd Add a separate data buffer for DexBackedDexFile 
For cdex files, offsets into the data section are specified relative to
the start of the data section, instead of relative to the start of the dex
file.

This adds a separate data buffer that can be used to resolve these
references.

906f4d67c1 Decouple the DexEntry for MultiDexContainer

separate entity, which returns the associated dex file.

2412f1f741 Remove isOdexFile, and rename hasOdexOpcodes to supportsOptimizedOpcodes 
isOdexFile was no longer being used, and hasOdexOpcodes had a slightly
misleading name, since it could potentially return true for an odex or
oat embedded dex file that didn't actually have any odex opcodes.

0d4443a19a Gracefully deal with code addresses that are out of range in MutableMethodImplementation 
The code addresses in debug info items are not verified, and may be out of
bounds. If this happens, we just clamp them to the maximum code address.
