// through a subclass with the declaring class having no TypeId in current DexFile.
|
// When we inline this getter, we're left with HLoadClass+HClinitCheck which cannot
|
// be merged back to the InvokeStaticOrDirect for implicit class init check.
|
// The declaring class is in the boot image, so the LoadClass can load it using the
|
// .data.bimg.rel.ro section. However, the ClinitCheck entrypoint was previously
|
// taking a type index of the declaring class and since we did not have a valid
|
// TypeId in the current DexFile, we erroneously provided the type index from the
|
// declaring DexFile and that caused a crash. This was fixed by changing the
|
// ClinitCheck entrypoint to take the Class reference from LoadClass.
