erik.corry@gmail.com	118a421067	Simplify the transitions in the Binary Op ICs. Now a single call to the runtime will both patch in the more specialized binary op stub and calculate the answer. This eliminates the need to call both the rest of the binary op and the patching runtime call. The runtime routines are altered to be more agressive in returning Smis so we don't get spurious heap numbers as inputs to binary ops while we are patching the binary op ICs.

sgjesse@chromium.org	e045ca6898	Better handling of stepping out of a function With the change in r4820 all return statements are now breakable like any statement, so stepping will stop before the return statement actually returning from a function. With this change the position when breaking in the function return (after executing the return statement) will be the actual end of the function. At this point the return value is available as it saved to the stack by the debug break at return handling. Added information on the actual value returned from the function to the debugger.

sgjesse@chromium.org	634fb9152c	More precise break points and stepping when debugging Added support for more precise break points when debugging and stepping. To achieve that additional nop instructions are inserted where breaking would otherwise be impossible. The number of nop instructions inserted are sufficient to make place for patching with a call to a debug break code stub. On Intel that is 5 nop's for 32-bit and 13 for 64-bit. Om ARM 3 nop instructions (12 bytes) are required. In order to avoid inserting nop's in to many places a simple ast checker have been added to check whether there are breakable code in a statement or expression. If it is possible to break in an expression no additional break enabeling code is inserted. Added break locations to the true and false part of a conditional expression. Added stepping tests to cover more constructs. These changes are only in the full compiler. Changed the default value for the option --debugger in teh d8 shell from true to false. The reason for this is that with --debugger turned on the full compiler will be used for all code in when running d8, which can be unexpeceted.

antonm@chromium.org	12f6306420	First phase of migration to new named property query callbacks. Eventually named property query callbacks will return attributes (as an integer) or an empty handle if property is not intercepted. To gradually migrate to this new API, USE_NEW_QUERY_CALLBACK macro would control if old or new style API is used. So the migration plan is: 1) introduce new API which should be explictily enabled; 2) switch to new API defining USE_NEW_QUERY_CALLBACK before include of <v8.h> (that would require changes to client code as well) 3) remove old API from v8 4) remove #define USE_NEW_QUERY_CALLBACK from clients.

antonm@chromium.org	ebba43f37a	Make intercepted properties retrievable only by getter to be not enumerable. Currently if there is no query callback, V8 finds out intercepted properties' attributes using getter: if getter returns not empty handle V8 treats such a property as property with NONE attribues which means this property is enumerable. However, if there is no enumerator, this property cannot be enumerated. Thus I think we should treat such properties as not enumerable. Drawback of this approach is now one has to implement both query and enumerator callbacks to implement enumerable intercepted properties.

vitalyr@chromium.org	ad0e38909f	Custom call IC-s for String.prototype.{charAt,charCodeAt}. These string methods can be composed from two basic blocks: charCodeAt and fromCharCode, both of which have fast cases for certain types of inputs. In this patch these two blocks are refactored to allow generating the fast cases without having to jump around the slow cases. In the slow cases since they can now be invoked both from inline runtime functions and from IC stubs we either have to save/restore state of the current frame or enter/leave a new internal frame. This is handled by new RuntimeCallHelper interface. Its implementation for virtual frame is based on FrameRegisterState class extracted from DeferredCode class.

ricow@chromium.org	95939ada29	Fix issue 720 making Object.defineProperty handle existing writable flags correctly. The existing version will overwrite the existing writable flag with false even in the case where no new value is given and the existing writable flag is true. The reason for the issue is that there is no check to see if the provided descriptor actually has a writable attribute. This causes us to use the default value (false) even in the case where nothing was provided. In addition, the existing tests makes wrong assumptions (that writable is always set to false if not provided) and has been changed to follow the specification.

sgjesse@chromium.org	22e4847fde	ARM: Update the full compiler to handle all code The full compiler is now complete on ARM as well. The syntax checker is still used to determine whether to use it for top level code or not during normal execution. When debugging is enabled all code will be compiled with the full compiler. This change removes the temporary flag --force-full-compiler and now the flag --always-full-compiler enables the full compiler for all code on all platforms. This also fixes building on Intel platform without debugger support (ENABLE_DEBUGGER_SUPPORT not defined) and adds full check for the full compiler for lazily compiled code.

sgjesse@chromium.org	19d98493fc	Add complete implementation of full compiler for the ia32 architecture This makes the full compiler handle all constructs on ia32. However the syntax checker for the full compiler is still the same so for both normal operation and with the flag --always-full-compiler the coverage of the full compiler will be the same. This is on preparation for improving the debugger break point experience where the plan is to only use code from full code generator when debugging JavaScript. Runs all tests on all three platforms in release and debug mode. The tests also run with both the following flags to the test runner --special-command="@ --nofull-compiler" --special-command="@ --always-full-compiler" The changes to the x64 and ARM architectures are mainly structural due to the change to EmitVariableAssignment to handle initialization of const variables.

mikhail.naganov@gmail.com	3d7ce8ac19	CPU profiler: add secure profiles by filtering out functions using security tokens. As several pages can run in a single V8 instance, it is possible to have functions from different security contexts intermixed in a single CPU profile. To avoid exposing function names from one page to another, filtering is introduced. The basic idea is that instead of capturing return addresses from stack, we're now capturing JSFunction addresses (as we anyway work only with JS stack frames.) Each JSFunction can reach out for context's security token. When providing a profile to a page, the profile is filtered using the security token of caller page. Any functions with different security tokens are filtered out (yes, we only do fast path check for now) and their ticks are attributed to their parents.

sgjesse@chromium.org	d25c36deee	ARM: Pass arguments to keyed store IC in registers The calling convention for keyed store IC on ARM is changed to receive the arguments value, key and receiver in registers r0, r1 and r2 instead of on the stack. When calling keyed store IC with a virtual frame the arguments are passed through the virtual frame and consumed by the call. Changed the register usage in the IC code to postpone spilling the registers holding value, key and receiver to the stack until making a call into the runtime system. Runs all the tests with: --special-command="@ --nofull-compiler" --special-command="@ --always-full-compiler" --special-command="@ --noenable-vfp3" Review URL: http://codereview.chromium.org/2116003 git-svn-id: http://v8.googlecode.com/svn/branches/bleeding_edge@4668 ce2b1a6d-e550-0410-aec6-3dcde31c8c00	2010-05-18 06:57:12 +00:00
sgjesse@chromium.org	02ca5fd8b2	ARM: Fix generating two ldr instructions in place of ldrd. When ldrd is not available two ldr instructions are generated. This fixes these in the case where the register used in the memory operand is the same as the first register in the register pair receiving the values. All tests now run on ARM with the flag --special-command="@ --noenable-vfp3". Running without VFP3 support in the simulator causes more ldrd instructions to be used, and the default build configuration does not utilize ldrd, but generated tow ldr instructions.
