The previous versions of Math.max and Math.min made it difficult to optimize those (that's why we already have custom code in Crankshaft), and due to lack of ideas what to do about the variable number of arguments, we will probably need to stick in special code in TurboFan as well; so inlining those builtins is off the table, hence there's no real advantage in having them around as "not quite JS" with extra work necessary in the optimizing compilers to still make those builtins somewhat fast in cases where we cannot inline them (also there's a tricky deopt loop in Crankshaft related to Math.min and Math.max, but that will be dealt with later). So to sum up: Instead of trying to make Math.max and Math.min semi-fast in the optimizing compilers with weird work-arounds support %_Arguments %_ArgumentsLength, we do provide the optimal code as native builtins instead and call it a day (which gives a nice performance boost on some benchmarks).

1. The placement of checks for negative zero has to be computed after all conversion instructions have been inserted. I separated the code into its own phase. 2. GVN need to take instruction flags into account when comparing instructions for redundancy.

If the instanceof stub was requested to deliver true/false objects as the result instead of 0/1 then 0/1 was actually returned if the builtin INSTANCE_OF ended up being called. This is now fixed.

In the shell sample don't print the result of executing a script, only evaluating expressions. Fixed issue when building samples on Windows using a shared V8 library. Added visibility option on Linux build which makes the generated library 18% smaller. Changed build system to accept multiple build modes in one build and generate seperate objects, libraries and executables for each mode. Removed deferred negation optimization (a * -b => -(a * b)) since this visibly changes operand conversion order. Improved parsing performance by introducing stack guard in preparsing. Without a stack guard preparsing always bails out with stack overflow. git-svn-id: http://v8.googlecode.com/svn/branches/bleeding_edge@16 ce2b1a6d-e550-0410-aec6-3dcde31c8c00
