luni/src/test/java/libcore/java/lang/reflect/parameter/README.txt

This directory contains the .smali files used to generate .dex files used
by libcore.java.lang.reflect.ParameterTest.

The use of .smali files allows construction of valid and invalid
system annotations for parameter metadata that are then tested in
ParameterTest.

Regenerate the .dex files with:

make smali
smali assemble libcore/luni/src/test/java/libcore/java/lang/reflect/parameter/ParameterMetdataTestClasses*.smali \
    -o libcore/luni/src/test/resources/libcore/java/lang/reflect/parameter/parameter_metadata_test_classes.dex

For reference, the valid smali code should be (roughly) the equivalent of the
following Java code when compiled using a compiler with .dex parameter metadata support
enabled.

The smali was generated using Jack to create a .dex file.

For example:

jack -D jack.java.source.version=1.8 \
  --output-dex . \
  -cp ${ANDROID_BUILD_TOP}/out/target/common/obj/JAVA_LIBRARIES/core-all_intermediates/classes.jack \
  src/test/java/libcore/java/lang/reflect/parameter/ParameterMetadataTestClasses.java

It was then decompiled using baksmali, hand modified, and a .dex generated from it using smali.

ParameterMetadataTestClasses* contain valid metadata.
MetadataVariations* contain variations on valid and invalid metdata that would be difficult to
generate from a .java file (i.e. invalid cases, null/empty parameter names).
