* Re-enable ParallelGC test for gcstress modeMathieu Chartier2015-01-071-2/+1
| | | | | | | Ran the test hundreds of times with gcstress without any failures. Bug: 16406852 Change-Id: Idd2d248bd43bfb20ad7313e12ce3dce85bea3de5
* Fix signal test to work with gcstressMathieu Chartier2015-01-072-3/+1
| | | | | | | | | | | | | We now avoid running GC if we are handling a stack overflow, this helps prevent running past the end of the stack overflow reserved bytes. Added logic in ThrowStackOverflowError to use a stack overflow exception without a stack trace if we fail to allocate the stack trace.

* ART: Fix verification of constructors.Stephen Kyle2014-12-224-0/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: A constructor must call its superclass constructor. However, if one replaces the invoke-direct superclass.<init>() instruction with a variety of instructions, the verifier would NOT complain that the superclass constructor hadn't been called. Detailed explanation: This was because if we are verifying the return-void insn of a constructor, then we check that the register line doesn't contain a register with an UninitializedThis type. With a method like follows: Class.<init>()V: return-void Then we hit the return-void, see the UninitializedThis, and fail the method. However, with a method like follows: Class.<init>()V: nop return-void Any insn that continues or branches onto a return-void instruction will mark all of the registers as Conflict. This meant that the check in return-void for an UninitializedThis residing the register line would _always_ pass if there were any insns before it - the entire line had been set to Conflict. The fix is to bring the check for an UninitializedThis forward to the point just before we set all registers to Conflict, if we're about to hit a return-void insn in a constructor. It still needs to be done again in the verification of return-void itself, to avoid the solo return-void case. This patch also deals with the case where the only remaining UninitializedThis reference is overwritten, to avoid a method like the following from getting through verification: Class.<init>()V: const/4 v0, 0 return-void Bug: 18800943 Change-Id: I2e317261844d3b6c78e35228669f3da173316570 Fuzzed-With: https://android-review.googlesource.com/#/c/119463/

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Redefine a back-edge to really mean an edge to a loop head instead of comparing instruction offsets. Generate suspend checks also on fall-through to a loop head; insert an extra GOTO for these edges. Add suspend checks to fused cmp instructions. Rewrite suspend check elimination to track whether there is an invoke on each path from the loop head to a given back edge, instead of using domination info to look for a basic block with invoke that must be on each path. Ignore invokes to intrinsics and move the optimization to a its own pass. The new loops in 109-suspend-check should prevent intrinsics and fused cmp-related regressions.

| |/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Now every architecture must provide a mapper between VRs parameters and physical registers. Additionally as a helper function architecture can provide a bulk copy helper for GenDalvikArgs utility. All other things becomes a common code stuff: GetArgMappingToPhysicalReg, GenDalvikArgsNoRange, GenDalvikArgsRange, FlushIns. Mapper now uses shorty representation of input parameters. This is required due to location are not enough to detect the type of parameter (fp or core). For the details see https://android-review.googlesource.com/#/c/113936/.

| * | Don't re-use arttest when calling loadLibrary.Nicolas Geoffray2014-12-031-10/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When Android's build environment variables are set with envsetup.sh, the test "works" ok, by getting a LinkageError because two class loaders try to load the same library. I guess that is the reason for the if (ExceptionCheck()) after the loading. However, if the environment variables are set manually, there are cases where the paths provided between a Java loadLibrary, and a native loadLibrary are different, so we end up loading the library twice. This makes the assertion line 32 fail on the second JNI_OnLoad call. In my particular environment, ANDROID_BUILD_TOP was something lie /foo/bar/..//. This change stops re-using the same library, and makes the expected outcome constant: the native call of loadLibrary with a non exist library must throw a LinkageError.
