| 1648 | calling a caught function in a catch clause. |
| 1649 | |
| 1650 | Inline array loads within loops directly in the code instead of |
| 1651 | always calling a stub. |

| 1709 | and added a stats-viewer tool. |
| 1710 | |
| 1711 | Fixed bug in upper/lower case mappings (issue 149). |
| 1712 | |
| 1713 | |

| 1734 | context of the associated global object. |
| 1735 | |
| 1736 | Treat byte-order marks as whitespace characters. |

| 1757 | |
| 1758 | Improved performance of Array.prototype.concat by moving the |
| 1759 | implementation to C++ (issue 123). |
| 1760 | |
| 1761 | Fixed heap growth policy to avoid growing old space to its maximum |
| 1762 | capacity before doing a garbage collection and fixed issue that |
| 1763 | would lead to artificial out of memory situations (issue 129). |
| 1764 | |
| 1765 | Fixed Date.prototype.toLocaleDateString to return the date in the |
| 1766 | same format as WebKit. |
| 1767 | |

| 1790 | |
| 1791 | Fixed bug that affected the value of an assignment to an element |
| 1792 | in certain cases (issue 116). |
| 1793 | |
| 1794 | Added GetPropertyNames functionality (issue 33) and extra Date |
| 1795 | functions (issue 77) to the API. |
| 1796 | |
| 1797 | Changed WeakReferenceCallback to take a Persistent<Value> instead |
| 1798 | of a Persistent<Object> (issue 101). |
| 1799 | |

| 1825 | specializing the code based on the string representation. |
| 1826 | |
| 1827 | Improve the handling of out-of-memory situations (issue 70). |
| 1828 | |
| 1829 | Improved performance of strict equality checks. |
| 1830 | |
| 1831 | Improved profiler output to make it easier to see anonymous |
| 1832 | functions. |
| 1833 | |
| 1834 | Improved performance of slow-case keyed loads. |
| 1835 | |
| 1836 | Improved property access performance by allocating a number of |
| 1837 | properties in the front object. |
| 1838 | |
| 1839 | Changed the toString behavior on the built-in object constructors |
| 1840 | to print [native code] instead of the actual source. Some web |
| 1841 | applications do not like constructors with complex toString |
| 1842 | results. |
| 1843 | |
| 1844 | |
| 1845 | 2008-10-06: Version 0.3.4 |
| 1846 | |
| 1847 | Changed Array.prototype.sort to use quick sort. |
| 1848 | |
| 1849 | Fixed code generation issue where leaving a finally block with |
| 1850 | break or continue would accumulate elements on the expression |
| 1851 | stack (issue 86). |
| 1852 | |
| 1853 | Made sure that the name accessor on functions returns the expected |
| 1854 | names for builtin JavaScript functions and C++ callback functions. |
| 1855 | |
| 1856 | Added fast case code for extending the property storage array of |
| 1857 | JavaScript objects. |
| 1858 | |
| 1859 | Ported switch statement optimizations introduced in version 0.3.3 |
| 1860 | to the ARM code generator. |
| 1861 | |
| 1862 | Allowed GCC to use strict-aliasing rules when compiling. |
| 1863 | |
| 1864 | Improved performance of arguments object allocation by taking care |
| 1865 | of arguments adaptor frames in the generated code. |
| 1866 | |
| 1867 | Updated the V8 benchmark suite to version 2. |
| 1868 | |
| 1869 | |
| 1870 | 2008-09-25: Version 0.3.3 |

| 1872 | Improved handling of relocation information to enable more |
| 1873 | peep-hole optimizations. |
| 1874 | |
| 1875 | Optimized switch statements where all labels are constant small |
| 1876 | integers. |
| 1877 | |
| 1878 | Optimized String.prototype.indexOf for common cases. |
| 1879 | |
| 1880 | Fixed more build issues (issue 80). |
| 1881 | |
| 1882 | Fixed a couple of profiler issues. |
| 1883 | |
| 1884 | Fixed bug where the body of a function created using the Function |
| 1885 | constructor was not allowed to end with a single-line comment |
| 1886 | (issue 85). |
| 1887 | |
| 1888 | Improved handling of object literals by canonicalizing object |
| 1889 | literal maps. This will allow JSON objects with the same set of |
| 1890 | properties to share the same map making inline caching work better |
| 1891 | for JSON objects. |
| 1892 | |
| 1893 | |
| 1894 | 2008-09-17: Version 0.3.2 |
| 1895 | |
| 1896 | Generalized the EvalCache into a CompilationCache and enabled it |
| 1897 | for scripts too. The current strategy is to retire all entries |
| 1898 | whenever a mark-sweep collection is started. |
| 1899 | |
| 1900 | Fixed bug where switch statements containing only a default case |
| 1901 | would lead to an unbalanced stack (issue 69). |
| 1902 | |
| 1903 | Fixed bug that made access to the function in a named function |
| 1904 | expression impossible in certain situations (issue 24). |
| 1905 | |
| 1906 | Fixed even more build issues. |
| 1907 | |
| 1908 | Optimized calling conventions on ARM. The conventions on ARM and |
| 1909 | IA-32 now match. |
| 1910 | |
| 1911 | Removed static initializers for flags and counters. |
| 1912 | |
| 1913 | Improved inline caching behavior for uncommon cases where lazily |
| 1914 | loading Date and RegExp code could force certain code paths go |
| 1915 | megamorphic. |
| 1916 | |
| 1917 | Removed arguments adaption for builtins written in C++. This |
| 1918 | makes Array.prototype.push and Array.prototype.pop slightly |
| 1919 | faster. |
| 1920 | |
| 1921 | |
| 1922 | 2008-09-11: Version 0.3.1 |
| 1923 | |
| 1924 | Fixed a number of build issues. |
| 1925 | |
| 1926 | Fixed problem with missing I-cache flusing on ARM. |
| 1927 | |
| 1928 | Changed space layout in memory management by splitting up |
| 1929 | code space into old data space and code space. |
| 1930 | |
| 1931 | Added utf-8 conversion support to the API (issue 57). |
| 1932 | |
| 1933 | Optimized repeated calls to eval with the same strings. These |
| 1934 | repeated calls are common in web applications. |
| 1935 | |
| 1936 | Added Xcode project file. |
| 1937 | |
| 1938 | Optimized a couple of Array operation. |
| 1939 | |
| 1940 | Fixed parser bug by checking for end-of-string when parsing break |
| 1941 | and continue (issue 35). |
| 1942 | |
| 1943 | Fixed problem where asian characters were not categorized as |
| 1944 | letters. |
| 1945 | |
| 1946 | Fixed bug that disallowed calling functions fetched from an array |
| 1947 | using a string as an array index (issue 32). |
| 1948 | |
| 1949 | Fixed bug where the internal field count on object templates were |
| 1950 | sometimes ignored (issue 54). |
| 1951 | |
| 1952 | Added -f option to the shell sample for compatibility with other |
| 1953 | engines (issue 18). |
| 1954 | |
| 1955 | Added source info to TryCatches in the API. |
| 1956 | |
| 1957 | Fixed problem where the seed for the random number generator was |
| 1958 | clipped in a double to unsigned int conversion. |
| 1959 | |
| 1960 | Fixed bug where cons string symbols were sometimes converted to |
| 1961 | non-symbol flat strings during GC. |
| 1962 | |
| 1963 | Fixed bug in error reporting when attempting to convert null to an |
| 1964 | object. |
| 1965 | |
| 1966 | |
| 1967 | 2008-09-04: Version 0.3.0 |
| 1968 | |
| 1969 | Added support for running tests on the ARM simulator. |
| 1970 | |
| 1971 | Fixed bug in the 'in' operator where negative indices were not |
| 1972 | treated correctly. |
| 1973 | |
| 1974 | Fixed build issues on gcc-4.3.1. |
| 1975 | |
| 1976 | Changed Date.prototype.toLocaleTimeString to not print the |
| 1977 | timezone part of the time. |
| 1978 | |
| 1979 | Renamed debug.h to v8-debug.h to reduce the risk of name conflicts |
| 1980 | with user code. |
| 1981 | |
| 1982 | |
| 1983 | 2008-09-02: Version 0.2.5 |
| 1984 | |
| 1985 | Renamed the top level directory 'public' to 'include'. |
| 1986 | |
| 1987 | Added 'env' option to the SCons build scripts to support |
| 1988 | overriding the ENV part of the build environment. This is mostly |
| 1989 | to support Windows builds in cases where SCons cannot find the |
| 1990 | correct paths to the Windows SDK, as these paths cannot be passed |
| 1991 | through shell environment variables. |
| 1992 | |
| 1993 | Enabled "Buffer Security Check" on for the Windows SCons build and |
| 1994 | added the linker option /OPT:ICF as an optimization. |
| 1995 | |
| 1996 | Added the V8 benchmark suite to the repository. |
| 1997 | |
| 1998 | |
| 1999 | 2008-09-01: Version 0.2.4 |
| 2000 | |
| 2001 | Included mjsunit JavaScript test suite and C++ unit tests. |
| 2002 | |
| 2003 | Changed the shell sample to not print the result of executing a |
| 2004 | script provided on the command line. |
| 2005 | |
| 2006 | Fixed issue when building samples on Windows using a shared V8 |
| 2007 | library. Added visibility option on Linux build which makes the |
| 2008 | generated library 18% smaller. |
| 2009 | |
| 2010 | Changed build system to accept multiple build modes in one build |
| 2011 | and generate separate objects, libraries and executables for each |
| 2012 | mode. |
| 2013 | |
| 2014 | Removed deferred negation optimization (a * -b => -(a * b)) since |
| 2015 | this visibly changes operand conversion order. |
| 2016 | |
| 2017 | Improved parsing performance by introducing stack guard in |
| 2018 | preparsing. Without a stack guard preparsing always bails out |
| 2019 | with stack overflow. |
| 2020 | |
| 2021 | Changed shell sample to take flags directly from the command-line. |
| 2022 | Added API call that implements this. |
| 2023 | |
| 2024 | Added load, quit and version functions to the shell sample so it's |
| 2025 | easier to run benchmarks and tests. |
| 2026 | |
| 2027 | Fixed issue with building samples and cctests on 64-bit machines. |
| 2028 | |
| 2029 | Fixed bug in the runtime system where the prototype chain was not |
| 2030 | always searched for a setter when setting a property that does not |
| 2031 | exist locally. |
| 2032 | |
| 2033 | |
| 2034 | 2008-08-14: Version 0.2.3 |
| 2035 | |
| 2036 | Improved performance of garbage collection by moving the |
| 2037 | function that updates pointers during compacting collection |
| 2038 | into the updating visitor. This gives the compiler a better |
| 2039 | chance to inline and avoid a function call per (potential) |
| 2040 | pointer. |
| 2041 | |
| 2042 | Extended the shell sample with a --runtime-flags option. |
| 2043 | |
| 2044 | Added Visual Studio project files for the shell.cc and |
| 2045 | process.cc samples. |
| 2046 | |
| 2047 | |
| 2048 | 2008-08-13: Version 0.2.2 |
| 2049 | |
| 2050 | Improved performance of garbage collection by changing the way |
| 2051 | we use the marking stack in the event of stack overflow during |
| 2052 | full garbage collection and by changing the way we mark roots. |
| 2053 | |
| 2054 | Cleaned up ARM version by removing top of stack caching and by |
| 2055 | introducing push/pop elimination. |
| 2056 | |
| 2057 | Cleaned up the way runtime functions are called to allow |
| 2058 | runtime calls with no arguments. |
| 2059 | |
| 2060 | Changed Windows build options to make sure that exceptions are |
| 2061 | disabled and that optimization flags are enabled. |
| 2062 | |
| 2063 | Added first version of Visual Studio project files. |
| 2064 | |
| 2065 | |
| 2066 | 2008-08-06: Version 0.2.1 |
| 2067 | |
| 2068 | Improved performance of unary addition by avoiding runtime calls. |
| 2069 | |
| 2070 | Fixed the handling of '>' and '<=' to use right-to-left conversion |
| 2071 | and left-to-right evaluation as specified by ECMA-262. |
| 2072 | |
| 2073 | Fixed a branch elimination bug on the ARM platform where incorrect |
| 2074 | code was generated because of overly aggressive branch |
| 2075 | elimination. |
| 2076 | |
| 2077 | Improved performance of code that repeatedly assigns the same |
| 2078 | function to the same property of different objects with the same |
| 2079 | map. |
| 2080 | |
| 2081 | Untangled DEBUG and ENABLE_DISASSEMBLER defines. The disassembler |
| 2082 | no longer expects DEBUG to be defined. |
| 2083 | |
| 2084 | Added platform-nullos.cc to serve as the basis for new platform |
| 2085 | implementations. |
| 2086 | |
| 2087 | |
| 2088 | 2008-07-30: Version 0.2.0 |
| 2089 | |
| 2090 | Changed all text files to have native svn:eol-style. |
| 2091 | |
| 2092 | Added a few samples and support for building them. The samples |
| 2093 | include a simple shell that can be used to benchmark and test V8. |
| 2094 | |
| 2095 | Changed V8::GetVersion to return the version as a string. |
| 2096 | |
| 2097 | Added source for lazily loaded scripts to snapshots and made |
| 2098 | serialization non-destructive. |
| 2099 | |
| 2100 | Improved ARM support by fixing the write barrier code to use |
| 2101 | aligned loads and stores and by removing premature locals |
| 2102 | optimization that relied on broken support for callee-saved |
| 2103 | registers (removed). |
| 2104 | |
| 2105 | Refactored the code for marking live objects during garbage |
| 2106 | collection and the code for allocating objects in paged |
| 2107 | spaces. Introduced an abstraction for the map word of a heap- |
| 2108 | allocated object and changed the memory allocator to allocate |
| 2109 | executable memory only for spaces that may contain code objects. |
| 2110 | |
| 2111 | Moved StringBuilder to utils.h and ScopedLock to platform.h, where |
| 2112 | they can be used by debugging and logging modules. Added |
| 2113 | thread-safe message queues for dealing with debugger events. |
| 2114 | |
| 2115 | Fixed the source code reported by toString for certain builtin |
| 2116 | empty functions and made sure that the prototype property of a |
| 2117 | function is enumerable. |
| 2118 | |
| 2119 | Improved performance of converting values to condition flags in |
| 2120 | generated code. |
| 2121 | |
| 2122 | Merged disassembler-{arch} files. |
| 2123 | |
| 2124 | |
| 2125 | 2008-07-28: Version 0.1.4 |
| 2126 | |
| 2127 | Added support for storing JavaScript stack traces in a stack |
| 2128 | allocated buffer to make it visible in shallow core dumps. |
| 2129 | Controlled by the --preallocate-message-memory flag which is |
| 2130 | disabled by default. |
| 2131 | |
| 2132 | |
| 2133 | 2008-07-25: Version 0.1.3 |
| 2134 | |
| 2135 | Fixed bug in JSObject::GetPropertyAttributePostInterceptor where |
| 2136 | map transitions would count as properties. |
| 2137 | |
| 2138 | Allowed aliased eval invocations by treating them as evals in the |
| 2139 | global context. This may change in the future. |
| 2140 | |
| 2141 | Added support for accessing the last entered context through the |
| 2142 | API and renamed Context::Current to Context::GetCurrent and |
| 2143 | Context::GetSecurityContext to Context::GetCurrentSecurityContext. |
| 2144 | |
| 2145 | Fixed bug in the debugger that would cause the debugger scripts to |
| 2146 | be recursively loaded and changed all disabling of interrupts to |
| 2147 | be block-structured. |
| 2148 | |
| 2149 | Made snapshot data read-only to allow it to be more easily shared |
| 2150 | across multiple users of V8 when linked as a shared library. |
| 2151 | |
| 2152 | |
| 2153 | 2008-07-16: Version 0.1.2 |
| 2154 | |
| 2155 | Fixed building on Mac OS X by recognizing i386 and friends as |
| 2156 | IA-32 platforms. |
| 2157 | |
| 2158 | Added propagation of stack overflow exceptions that occur while |
| 2159 | compiling nested functions. |
| 2160 | |
| 2161 | Improved debugger with support for recursive break points and |
| 2162 | handling of exceptions that occur in the debugger JavaScript code. |
| 2163 | |
| 2164 | Renamed GetInternal to GetInternalField and SetInternal to |
| 2165 | SetInternalField in the API and moved InternalFieldCount and |
| 2166 | SetInternalFieldCount from FunctionTemplate to ObjectTemplate. |
| 2167 | |
| 2168 | |
| 2169 | 2008-07-09: Version 0.1.1 |
| 2170 | |
| 2171 | Fixed bug in stack overflow check code for IA-32 targets where a |
| 2172 | non-tagged value in register eax was pushed to the stack. |
| 2173 | |
| 2174 | Fixed potential quadratic behavior when converting strings to |
| 2175 | numbers. |
| 2176 | |
| 2177 | Fixed bug where the return value from Object::SetProperty could |
| 2178 | end up being the property holder instead of the written value. |
| 2179 | |
| 2180 | Improved debugger support by allowing nested break points and by |
| 2181 | dealing with stack-overflows when compiling functions before |
| 2182 | setting break points in them. |
| 2183 | |
| 2184 | |
| 2185 | 2008-07-03: Version 0.1.0 |
| 2186 | |
| 2187 | Initial export. |
