bmeurer@chromium.org	7a2c253e24	Move OS/compiler/feature detection to public v8config.h header. ... From now on the v8config.h header should be the one and only file where we do (freaky) checks to detect OS, C++ compiler or certain compiler features. Since we need that both internally and for the public API, the new v8config.h is the proper place to add (everything is prefixed with V8_ so we are safe).

bmeurer@chromium.org	a04490517a	ARM: Fix register misuse bug in Allocate(). ... The bug is triggered if flags contains DOUBLE_ALIGNMENT and the object_size is not an ARM immediate value. In this case, the code for DOUBLE_ALIGNMENT uses the scratch2 register, which is aliased to obj_size_reg containing the object_size. Instead of pre-loading the object_size, which is difficult since we are out of registers here, we simply generate a non-empty sequence of add instructions for the addition of the constant object_size (carefully handling possible overflow in each step). Also turn static ASSERT into STATIC_ASSERT in Allocate().

svenpanne@chromium.org	f0305bd83e	Instance-type-related fixes and cleanup. ... Things got quite a bit out of sync (don't we all love copy-n-paste?): * TypeToString didn't handle SLICED_STRING_TYPE, SLICED_ASCII_STRING_TYPE, FIXED_DOUBLE_ARRAY_TYPE, JS_FUNCTION_PROXY_TYPE and JS_DATE_TYPE. * INSTANCE_TYPE_LIST was missing entries for SLICED_ASCII_STRING_TYPE, JS_SET_TYPE, and JS_MAP_TYPE. To improve this maintenance nightmare a little bit, the missing instance types were added to the INSTANCE_TYPE_LIST macro and this list is now used via our beloved 2nd order macro technique in TypeToString. As a side-effect, the strings returned by TypeToString have a "_TYPE" suffix now, but this doesn't really matter and is a small price to pay for consistency. Removed INVALID_TYPE on the way, it had no real use.

yangguo@chromium.org	8fb95efdda	Improve internal stringifcation for custom Error objects. ... If an developer attempts to "subclass" Error by running `MyError.prototype = new Error();`, then the internal v8::Message object that's produced and handed off to `window.onerror` handlers is poorly stringified as "[object Object]". This patch adjusts the stringification process for these objects to include not only native Error objects, but also objects that have Error in their prototype chain, and haven't overwritten Error.toString with some custom variant.

rossberg@chromium.org	92bd4d1f2d	I found this working on ... https://codereview.chromium.org/19541010/ The main problem is that if you called Object.getNotifier(obj) on an object, %SetObserved(object) would never get called on it, and thus it would be unobservable (new test added for this). Additionally, Runtime::SetObserved was asserting obj->IsJSObject() which would fail if called on a proxy. It just happens that our existing test always called getNotifier() before Object.observe on proxies, and thus we never previously attempted to transition the map of a proxy. Both issues are now fixed and properly tested.

loislo@chromium.org	d2c443b774	Extract hardcoded error strings into a single place and replace them with enum. ... I'd like to propagate bailout reason to cpu profiler. So I need to save it into heap object SharedFunctionInfo. But: 1) all bailout reason strings spread across all the sources. 2) they are native strings and if I convert them into String then I may have a performance issue. 3) one byte is enough for 184 bailout reasons. Otherwise we need 8 bytes for the pointer. Also I think it would be nice to have error strings collected in one place. In that case we will get additional benefits: It allows us to keep this set of messages under control. It gives us a chance to internationalize them. It slightly reduces the binary footprint. From the other hand the developers have to add new strings into that enum.

bmeurer@chromium.org	a4c072ed47	Fix a crash when generating forward jumps to labels at very high assembly offsets ... The first jump to a specific label was marked as jump to absolute position -4. This value was stored in the assembly as a branch to a offset (-4 - (instruction offset + 8)). The offset is only 24 bit long on ARM. Thus instruction offsets higher than 2^23 - 12 would overflow the offset. Fix by denoting the first jump to a label by storing the jump instruction location as the target. This will result in offset of -8, which of course always fits in the branch instruction.

loislo@chromium.org	141ada02f2	Logger: introduce abstract interface for CodeEvent listeners. ... New abstract class CodeEventListener was created. CodeEventLogger which is the base class for Jit, LowLevel and CodeAddressMap loggers was inherited from CodeEventListener. CodeAddressMap class was moved to serializer.cc because serializer is the only user for it. Actually it collects code names and pushes them to the standard log as SnapshotCodeNameEvent. So I extracted this code into separate function CodeNameEvent. It happens that this method works only when Serializer serializes an object. So I added direct log call there. CodeEventLogger class declaration was moved to the header because CodeAddressMap needs it. The code for the nested class CodeEventLogger::NameBuffer was left in the cc file. CpuProfiler now is inherit CodeEventListener but not used the loggers infrastructure yet due to the complex initialization schema. I'd like to fix that in a separate cl.

yangguo@chromium.org	f5e6fbef6e	move 32 bit heap hint on sunos ... Setting the V8 heap at or near 0x20000000 on 32bit sunos only allows 512 MB of heap space, instead on sunos move this to 0x80000000. To quote the comment For our Solaris/illumos mmap hint, we pick a random address in the bottom half of the top half of the address space (that is, the third quarter). Because we do not MAP_FIXED, this will be treated only as a hint -- the system will not fail to mmap() because something else happens to already be mapped at our random address. We deliberately set the hint high enough to get well above the system's break (that is, the heap); Solaris and illumos will try the hint and if that fails allocate as if there were no hint at all. The high hint prevents the break from getting hemmed in at low values, ceding half of the address space to the system heap.

yurys@chromium.org	97f8f91bb5	Fix call stack sampling for the case when native callback invokes JS function ... The SafeStackFrameIterator used by CPU profiler checked if Isolate::c_entry_fp is null and if it is not it would think that the control flow currently is in some native code. This assumption is wrong because the native code could have called a JS function but JSEntryStub would not reset c_entry_fp to NULL in that case. This CL adds a check in SafeStackFrameIterator::IsValidTop for the case when there is a JAVA_SCRIPT frame on top of EXIT frame. Also this CL changes ExternalCallbackScope behavior to provide access to the whole stack of the scope objects instead of only top one. This allowed to provide exact callback names for those EXIT frames where external callbacks are called. Without this change it was possible only for the top most native call.

rossberg@chromium.org	02649f08bc	Implement simple effect typing for variables ... For that, we maintain an abstract store typing of all variables with LOCAL location (i.e., those that do not escape the function's own scope). We treat assignments as sequential effects that modify this store. When control flow branches, we have to compute the disjunction of possible effects. To that end, we represent the store as a stack of effect sets, such that we can cheaply push and pop "local" effects when control flow has to branch. In cases of non-local control transfer from an unknown source, we currently erase all knowledge about the store. The 'switch' statement is still to come.

This approach is error prone, e.g. on x64 sizeof(AtomicWord) is 8 while sizeof(int) is 4. Moreover the queue needs such marker only at the beginning of chunk.

adamk@chromium.org	fab9f4e126	[Object.observe] Lazily allocate callbackInfo structure ... This patch allows callbacks to lazily allocate the InternalArray which is used to store pendingChangeRecords. This moves some of the expense of observation to the case where changes actually occurred. When there are no pendingChangeRecords, the callbackInfo structure is a number which is the callbacks priority. Whenever a changeRecord is enqueued to the callback, it "normalizes" to be an InternalArray with a priority property. Immediately before its changeRecords are delivered, it returns to its optimized state. --- Note: Naming confusion resolved: This patch corrects some naming confusion in object-observe.js. Previously, we used the terms "callback" and "observer" to mean roughly the same thing, and overloaded the term "observer" to be both the callback itself and the *registration* on a object to observe (which now includes an accept map). This patch resolves this confusion: "object" (objectInfo, objectInfoMap): This refers to the observed object and its structures "callback" (callbackInfo, callbackInfoMap): This refers to the callback to whom change records may be delivered "observer" (objectInfo.changeObservers): This refers to a registration to observe a given object by a given callback with the specified accept list. --- R=rossberg@chromium.org Review URL: https://codereview.chromium.org/19132002 Patch from Rafael Weinstein <rafaelw@chromium.org>. git-svn-id: http://v8.googlecode.com/svn/branches/bleeding_edge@15682 ce2b1a6d-e550-0410-aec6-3dcde31c8c00	2013-07-15 22:16:30 +00:00
