| * ART: fix highest PC values removal in SrcMap.DeltaFormat()Yevgeny Rouban2014-09-161-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | The conversion from absolute to offset Line Number Table values mistakenly removed all values less than the highest one, which resulted in clearing all the table. The fix is to use the reverse condition finding the highest correct PC value in the sorted table.

| * Fix a bug in the register allocator.Nicolas Geoffray2014-09-163-1/+61
| | | | | | | | | | | | | | | | We need to take the live interval that starts first to know until when a register is free, instead of using the live interval that is last in the inactive list. Change-Id: I2c9f87481ff1b4fc7b9948db7559b8d3b11d84ce

| * | ART: Make elf loading not abortAndreas Gampe2014-09-158-188/+456
|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | Changes elf_file code to use less CHECKs and instead return error values (usually nullptr). This avoids aborts. In oat_file, when loading an oat file fails, try to unlink at. If this succeeds, on the next run we may compile again.

| * Fix stale root error in verifierMathieu Chartier2014-09-125-10/+41
|/ | | | | | | | | | | | | | | There was a stale root error caused by the static roots from the reg types. These were visitied if there was an active verifier in the method_verifiers_ but this is not always the case when a GC is run. The fix is to always visit the static method verifier roots. This only showed up as a bug without an image since these roots were primitive classes and always in the image, and therefore didn't ever need to be updated due to moving GC.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Reduce virtual method dispatch in the method verifier and make more code inline-able. Add a StringPiece with const char* equality operator to avoid redundant StringPieces and strlens. Remove back link from register line to verifier and pass as argument to reduce size of RegisterLine. Remove instruction length from instruction flags and compute from the instruction, again to reduce size. Add suspend checks to resolve and verify to allow for more easy monitor inflation and reduce contention on Locks::thread_list_suspend_thread_lock_. Change ThrowEarlierClassFailure to throw pre-allocated exception. Avoid calls to Thread::Current() by passing self. Template specialize IsValidClassName. Make ANR reporting with SIGQUIT run using checkpoints rather than suspending all threads. This makes the stack/lock analysis less lock error prone.
