423 Use 'full compiler' when debugging is active. This should increase
424 the density of possible break points, making single step more fine
425 grained. This will only take effect for functions compiled after

1611 sub strings.
1612
1613 Fixed bug in code generation for large switch statements on ARM.

1615 Fixed bug that caused V8 to change the global object template
1616 passed in by the user.
1617
1618 Changed the API for creating object groups used during garbage
1619 collection. Entire object groups are now passed to V8 instead of
1620 individual members of the groups.

1647 interface.
1648
1649 Changed the type of names of counters from wchar_t to char.
1650

1655 Added support in the d8 developer shell for memory-mapped counters
1656 and added a stats-viewer tool.
1657
1658 Fixed bug in upper/lower case mappings (issue 149).
1659
iposva@chromium.org96f667e2008-11-26 23:48:02 +00001660

1677 Fixed bug in date code that made certain date functions return -0
1678 instead of 0 for dates before the epoch.
1679
1680 Restricted applications of eval so it can only be used in the
1681 context of the associated global object.
1682
1683 Treat byte-order marks as whitespace characters.

1704
1705 Improved performance of Array.prototype.concat by moving the
1706 implementation to C++ (issue 123).
1707
1708 Fixed heap growth policy to avoid growing old space to its maximum
1709 capacity before doing a garbage collection and fixed issue that

1736 object and the global object proxy.
1737
1738 Fixed bug that affected the value of an assignment to an element
1739 in certain cases (issue 116).
1740
1741 Added GetPropertyNames functionality (issue 33) and extra Date
1742 functions (issue 77) to the API.
1743
1744 Changed WeakReferenceCallback to take a Persistent<Value> instead
1745 of a Persistent<Object> (issue 101).
1746
1747 Fixed issues with message reporting for exceptions in try-finally
1748 blocks (issues 73 and 75).

1764 from the hash-code.
1765
1766 Changed string search algorithm used in indexOf from KMP to
1767 Boyer-Moore.
1768
1769 Improved the generated code for the instanceof operator.
1770
1771 Improved performance of slow-case string equality checks by
1772 specializing the code based on the string representation.
1773
1774 Improve the handling of out-of-memory situations (issue 70).
1775
1776 Improved performance of strict equality checks.
1777

1783 Improved property access performance by allocating a number of
1784 properties in the front object.
1785
1786 Changed the toString behavior on the built-in object constructors
1787 to print [native code] instead of the actual source. Some web
1788 applications do not like constructors with complex toString
1789 results.

1793
1794 Changed Array.prototype.sort to use quick sort.
1795
1796 Fixed code generation issue where leaving a finally block with
1797 break or continue would accumulate elements on the expression
1798 stack (issue 86).
1799
1800 Made sure that the name accessor on functions returns the expected
1801 names for builtin JavaScript functions and C++ callback functions.
1802
1803 Added fast case code for extending the property storage array of
1804 JavaScript objects.
1805
1806 Ported switch statement optimizations introduced in version 0.3.3
1807 to the ARM code generator.
1808
1809 Allowed GCC to use strict-aliasing rules when compiling.
1810
1811 Improved performance of arguments object allocation by taking care
1812 of arguments adaptor frames in the generated code.
1813
1814 Updated the V8 benchmark suite to version 2.

1820 peep-hole optimizations.
1821
1822 Optimized switch statements where all labels are constant small
1823 integers.
1824
1825 Optimized String.prototype.indexOf for common cases.
1826
1827 Fixed more build issues (issue 80).
1828
1829 Fixed a couple of profiler issues.
1830
1831 Fixed bug where the body of a function created using the Function
1832 constructor was not allowed to end with a single-line comment
1833 (issue 85).
1834
1835 Improved handling of object literals by canonicalizing object
1836 literal maps. This will allow JSON objects with the same set of
1837 properties to share the same map making inline caching work better
1838 for JSON objects.

1842
1843 Generalized the EvalCache into a CompilationCache and enabled it
1844 for scripts too. The current strategy is to retire all entries
1845 whenever a mark-sweep collection is started.
1846
1847 Fixed bug where switch statements containing only a default case
1848 would lead to an unbalanced stack (issue 69).
1849
1850 Fixed bug that made access to the function in a named function
1851 expression impossible in certain situations (issue 24).
1852
1853 Fixed even more build issues.
1854
1855 Optimized calling conventions on ARM. The conventions on ARM and
1856 IA-32 now match.
1857
1858 Removed static initializers for flags and counters.
1859
1860 Improved inline caching behavior for uncommon cases where lazily
1861 loading Date and RegExp code could force certain code paths go
1862 megamorphic.
1863
1864 Removed arguments adaption for builtins written in C++. This
1865 makes Array.prototype.push and Array.prototype.pop slightly
1866 faster.
1867
1868
ager@chromium.org9258b6b2008-09-11 09:11:10 +000018692008-09-11: Version 0.3.1
1870
1871 Fixed a number of build issues.
1872
1873 Fixed problem with missing I-cache flusing on ARM.
1874
1875 Changed space layout in memory management by splitting up
1876 code space into old data space and code space.
1877
1878 Added utf-8 conversion support to the API (issue 57).
1879
1880 Optimized repeated calls to eval with the same strings. These
1881 repeated calls are common in web applications.
1882
1883 Added Xcode project file.
1884
1885 Optimized a couple of Array operation.
1886
1887 Fixed parser bug by checking for end-of-string when parsing break
1888 and continue (issue 35).
1889
1890 Fixed problem where asian characters were not categorized as
1891 letters.
1892
1893 Fixed bug that disallowed calling functions fetched from an array
1894 using a string as an array index (issue 32).
1895
1896 Fixed bug where the internal field count on object templates were
1897 sometimes ignored (issue 54).
1898
1899 Added -f option to the shell sample for compatibility with other
1900 engines (issue 18).
1901
1902 Added source info to TryCatches in the API.
1903
1904 Fixed problem where the seed for the random number generator was
1905 clipped in a double to unsigned int conversion.
1906
1907 Fixed bug where cons string symbols were sometimes converted to
1908 non-symbol flat strings during GC.
1909
1910 Fixed bug in error reporting when attempting to convert null to an
1911 object.

1916 Added support for running tests on the ARM simulator.
1917
1918 Fixed bug in the 'in' operator where negative indices were not
1919 treated correctly.
1920
1921 Fixed build issues on gcc-4.3.1.
1922
1923 Changed Date.prototype.toLocaleTimeString to not print the
1924 timezone part of the time.
1925
1926 Renamed debug.h to v8-debug.h to reduce the risk of name conflicts
1927 with user code.
1928
1929
v8.team.kasperl727e9952008-09-02 14:56:44 +000019302008-09-02: Version 0.2.5
1931
1932 Renamed the top level directory 'public' to 'include'.
1933
1934 Added 'env' option to the SCons build scripts to support
1935 overriding the ENV part of the build environment. This is mostly
1936 to support Windows builds in cases where SCons cannot find the
1937 correct paths to the Windows SDK, as these paths cannot be passed
1938 through shell environment variables.
1939
1940 Enabled "Buffer Security Check" on for the Windows SCons build and
1941 added the linker option /OPT:ICF as an optimization.
1942
1943 Added the V8 benchmark suite to the repository.
1944
1945
mads.s.ager@gmail.com9a4089a2008-09-01 08:55:01 +000019462008-09-01: Version 0.2.4
1947
1948 Included mjsunit JavaScript test suite and C++ unit tests.
1949
1950 Changed the shell sample to not print the result of executing a
1951 script provided on the command line.
1952
1953 Fixed issue when building samples on Windows using a shared V8
1954 library. Added visibility option on Linux build which makes the
1955 generated library 18% smaller.
1956
1957 Changed build system to accept multiple build modes in one build
1958 and generate separate objects, libraries and executables for each
1959 mode.
1960
1961 Removed deferred negation optimization (a * -b => -(a * b)) since
1962 this visibly changes operand conversion order.
1963
1964 Improved parsing performance by introducing stack guard in
1965 preparsing. Without a stack guard preparsing always bails out
1966 with stack overflow.
1967
1968 Changed shell sample to take flags directly from the command-line.
1969 Added API call that implements this.
1970
1971 Added load, quit and version functions to the shell sample so it's
1972 easier to run benchmarks and tests.
1973
1974 Fixed issue with building samples and cctests on 64-bit machines.
1975
1976 Fixed bug in the runtime system where the prototype chain was not
1977 always searched for a setter when setting a property that does not
1978 exist locally.

1982
1983 Improved performance of garbage collection by moving the
1984 function that updates pointers during compacting collection
1985 into the updating visitor. This gives the compiler a better
1986 chance to inline and avoid a function call per (potential)
1987 pointer.
1988
1989 Extended the shell sample with a --runtime-flags option.
1990
1991 Added Visual Studio project files for the shell.cc and
1992 process.cc samples.

mads.s.ager31e71382008-08-13 09:32:07 +00001996
1997 Improved performance of garbage collection by changing the way
1998 we use the marking stack in the event of stack overflow during
1999 full garbage collection and by changing the way we mark roots.
2000
2001 Cleaned up ARM version by removing top of stack caching and by
2002 introducing push/pop elimination.
2003
2004 Cleaned up the way runtime functions are called to allow
2005 runtime calls with no arguments.
2006
2007 Changed Windows build options to make sure that exceptions are
2008 disabled and that optimization flags are enabled.
2009
2010 Added first version of Visual Studio project files.
2011
2012

mads.s.ager@gmail.com769cc962008-08-06 10:02:49 +00002014
2015 Improved performance of unary addition by avoiding runtime calls.
2016
2017 Fixed the handling of '>' and '<=' to use right-to-left conversion
2018 and left-to-right evaluation as specified by ECMA-262.
2019
2020 Fixed a branch elimination bug on the ARM platform where incorrect
2021 code was generated because of overly aggressive branch
2022 elimination.
2023
2024 Improved performance of code that repeatedly assigns the same
2025 function to the same property of different objects with the same
2026 map.
2027
2028 Untangled DEBUG and ENABLE_DISASSEMBLER defines. The disassembler
2029 no longer expects DEBUG to be defined.
2030
2031 Added platform-nullos.cc to serve as the basis for new platform
2032 implementations.

kasper.lund7276f142008-07-30 08:49:36 +00002036
2037 Changed all text files to have native svn:eol-style.
2038
2039 Added a few samples and support for building them. The samples
2040 include a simple shell that can be used to benchmark and test V8.
2041
2042 Changed V8::GetVersion to return the version as a string.
2043
2044 Added source for lazily loaded scripts to snapshots and made
2045 serialization non-destructive.
2046
2047 Improved ARM support by fixing the write barrier code to use
2048 aligned loads and stores and by removing premature locals
2049 optimization that relied on broken support for callee-saved
2050 registers (removed).
2051
2052 Refactored the code for marking live objects during garbage
2053 collection and the code for allocating objects in paged
2054 spaces. Introduced an abstraction for the map word of a heap-
2055 allocated object and changed the memory allocator to allocate
2056 executable memory only for spaces that may contain code objects.
2057
2058 Moved StringBuilder to utils.h and ScopedLock to platform.h, where
2059 they can be used by debugging and logging modules. Added
2060 thread-safe message queues for dealing with debugger events.
2061
2062 Fixed the source code reported by toString for certain builtin
2063 empty functions and made sure that the prototype property of a
2064 function is enumerable.
2065
2066 Improved performance of converting values to condition flags in
2067 generated code.
2068
2069 Merged disassembler-{arch} files.

2074 Added support for storing JavaScript stack traces in a stack
2075 allocated buffer to make it visible in shallow core dumps.
2076 Controlled by the --preallocate-message-memory flag which is
2077 disabled by default.
2078
2079
mads.s.agercbaa0602008-08-14 13:41:48 +000020802008-07-25: Version 0.1.3
kasper.lund44510672008-07-25 07:37:58 +00002081
2082 Fixed bug in JSObject::GetPropertyAttributePostInterceptor where
2083 map transitions would count as properties.
2084
2085 Allowed aliased eval invocations by treating them as evals in the
2086 global context. This may change in the future.
2087
2088 Added support for accessing the last entered context through the
2089 API and renamed Context::Current to Context::GetCurrent and
2090 Context::GetSecurityContext to Context::GetCurrentSecurityContext.
2091
2092 Fixed bug in the debugger that would cause the debugger scripts to
2093 be recursively loaded and changed all disabling of interrupts to
2094 be block-structured.
2095
2096 Made snapshot data read-only to allow it to be more easily shared
2097 across multiple users of V8 when linked as a shared library.

2102 Fixed building on Mac OS X by recognizing i386 and friends as
2103 IA-32 platforms.
2104
2105 Added propagation of stack overflow exceptions that occur while
2106 compiling nested functions.
2107
2108 Improved debugger with support for recursive break points and
2109 handling of exceptions that occur in the debugger JavaScript code.
2110
2111 Renamed GetInternal to GetInternalField and SetInternal to

kasper.lundbd3ec4e2008-07-09 11:06:54 +00002117
2118 Fixed bug in stack overflow check code for IA-32 targets where a
2119 non-tagged value in register eax was pushed to the stack.
2120
2121 Fixed potential quadratic behavior when converting strings to
2122 numbers.
2123
2124 Fixed bug where the return value from Object::SetProperty could
2125 end up being the property holder instead of the written value.
2126
2127 Improved debugger support by allowing nested break points and by
2128 dealing with stack-overflows when compiling functions before
2129 setting break points in them.
