* Rename register to conform to instruction formatLogan Chien2011-09-011-42/+54
| | | | | | | | | For instruction format 35c, 41c, 52c, and 5rc, the register name was different from the Dalvik Instruction Format document, and InstrUtils.cpp of libdex. This commit updates the name, so that they will look consistent. Change-Id: I857b1f9c1ac7178dc147d0019df589c9c6d102e1

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The "all stubs" interpreter is the recommended starting point for anyone creating a "fast" interpreter on a new CPU. This cleans up some minor bit rot in the code and documentation. Bug 3452689 Change-Id: I6bc3b0b5da11955d842d5fc5f16cb1a2209d4a89

| * | Ensure word atomicity in System.arraycopyAndy McFadden2011-02-041-2/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The VM needs to ensure that updates to 16-bit and 32-bit fields and array elements happen atomically. System.arraycopy was calling memmmove(), which in bionic happens to copy a byte at a time. The new plan is to have bionic provide a platform-optimized memmove variant that makes guarantees about word sizes. If it is not present (either because it hasn't been written for the current platform, or we're not linking against bionic), we will use a trivial copy loop. We assume that the memmove-by-word implementation does whatever it needs to for best performance. For example, if the function determines that memcpy() is word-safe and will be faster, it can call that. The VM no longer makes assumptions about the internal workings of libc functions. I also rearranged the code to avoid making indirect calls, reading function addresses from memory, and using integer multiplication instructions when a simple shift will do. (gcc now generates the whole thing as one function.) Also, added some primitive array copy tests to 011-array-copy. Bug 3398352 Change-Id: I4677ee1c87998697a93e61f39a48b3f391e8e11b

* | Move dx.dex.code.DalvOps -> dx.io.Opcodes.Dan Bornstein2011-01-301-10/+11
| | | | | | | | | | | | | | | | | | This breaks a nascent circular dependency, keeping dx.io the lower layer. Bonus: While I was in the territory, I clarified the data payload opcodes, including adding explicit constants for them. Change-Id: I8655064ebc3b5713cbb4a6c83bcc90984393701f
* | Basic facility to read/write bytecode.Dan Bornstein2011-01-301-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | These classes are meant for reading and writing bytecode at the lowest possible level, in particular without layering any interpretation of the instructions beyond understanding the instruction formats. (For example, constant indices remain numbers and aren't tied to objects representing constants.) This patch represents a work-in-progress that compiles but is as yet not hooked up to anything else. Hooking it all up will happen in one or more follow-on patches. Change-Id: Ifd3b3ff0925dc9dc3d82e507dc1be83cb560031d

* Check monitors during bytecode verificationAndy McFadden2010-11-231-0/+32
| | | | | | | | | | | | | | | | | | | | | | | | | This adds tracking of monitor-enter and monitor-exit instructions to the bytecode verifier. The idea is to guarantee that all lock operations in a method are paired with unlock operations, whether the method completes normally or abnormally. Because of an issue in "dx", the code only verifies that the operation stack has the right size at all times. We do not yet confirm that the correct monitor is being unlocked by monitor-exit (the code is present but ifdefed out). Also, when monitor verification is enabled, we do not add the "can throw" path from monitor-exit to the work list, potentially causing some "dead code" warnings. (Not coincidentally, "dead code" checking is now only enabled in libdvm_assert.so.) Overall increase in bootstrap verification time is about 9%, dropping to 6% when the new checks are disabled. The feature is currently disabled by default. -Xverifyopt:checkmon enables it. Bug 2534655 Change-Id: I0eac54ce2623fb1d48cc80889fcdb4fd69de3231

* Spec/implementation harmony.Dan Bornstein2010-11-091-28/+67
| | | | | | | | | | | | | I did two things here: (1) made the lettering for formats 35c and 35ms match how things are actually implemented; and (2) formally defined formats 35mi and 3rmi, to correspond to the inline linked formats actually used in our current implementation. In neither case does this change the meaning of the spec in any substantive way. The first case is just about labels, and the second case is just about (from the standpoint of the spec) a suggestion.
