1. Replaces --crankshaft with --opt in tests. 2. Also fixes presubmit to check for --opt flag when assertOptimized is used. 3. Updates testrunner/local/variants.py and v8_foozie.py to use --opt flag. This would mean, nooptimize variant means there are no optimizations. Not even with %OptimizeFunctionOnNextCall.

The mentioned asserts did not work properly with interpreted and turbofanned functions. To fix this issue %GetOptimizationStatus() now returns a set of flags instead of a single value. This CL also adds more helper functions to mjsunit, like isNeverOptimize(), isAlwaysOptimize(), isOptimized(fun), etc. BUG=v8:5890 Review-Url: https://codereview.chromium.org/2654733004 Cr-Original-Commit-Position: refs/heads/master@{#42703} Committed: https://chromium.googlesource.com/v8/v8/+/d1ddec785725a184fe6d01bd0813262e3ba24966 Review-Url: https://codereview.chromium.org/2654733004 Cr-Commit-Position: refs/heads/master@{#42731}

This CL adds --crankshaft and --no-always-opt flags to the tests that use assertOptimized() and assertUnoptimized() respectively. This CL also adds presubmit checks that ensure that tests have the proper flags set. BUG=v8:5890 Review-Url: https://codereview.chromium.org/2653753007 Cr-Commit-Position: refs/heads/master@{#42709}

Arithmetic right shifting is *not* division in two's complement representation, only in one's complement. So we convert to one's complement, shift, and go back to two's complement. By permutating the last steps, one can get efficient branch-free code. This insight comes from the paleozoic era of computer science, see the paper from 1976: Guy Lewis Steele Jr.: "Arithmetic Shifting Considered Harmful" ftp://publications.ai.mit.edu/ai-publications/pdf/AIM-378.pdf This results in better and more correct code than our previous "neg/shift/neg" dance.

If the divisor is a Power-of-2 constant, we could use shifts instead of the expensive idiv instructions, which also loose the register constraints.

This fixes a corner case when the instance prototype of a function is changed while inobject slack tracking is still in progress. This caused the intial map to be unrelated for functions with the same shared info and hence the shared construct stub is no longer generic enough to work for all those functions.

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
