We fall back from irregexp to the experimental engine if a backtrack limit is exceeded and the experimental engine can handle the regexp. The feature can be turned on with a boolean flag, and an uint-valued flag controls the default backtrack limit. For regexps that are constructed with an explicit backtrack limit (API, %NewRegExpWithBacktrackLimit), we choose the lower of the explicit and default backtrack limits. The default backtrack limit does not apply to regexps that can't be handled by the experimental engine, and for such regexps an explicitly specified backtrack limit is handled as before by returning null if we exceed it.

... between the interpreter and generated code. Prior to this CL, pre- and post conditions on the output register array differed between the interpreter and generated code. Interpreter Pre: `output` fits captures and temporary registers. Post: None. Generated code Pre: `output` fits capture registers. Post: `output` is modified if and only if the match succeeded. This CL changes the interpreter to match generated code pre- and post conditions by allocating space for temporary registers inside the interpreter. Drive-by: Add MaxRegisterCount, RegistersForCaptureCount helpers.

V8 uses a backtracking regexp engine, which has the caveat that some regexp patterns can have exponential runtime behavior when excessive backtracking is involved. Especially when regexp patterns are user-controlled, it would be useful to be able to set an upper limit for a single regexp execution. This CL takes an initial step in that direction by adding a backtracking limit (intended to approximate execution time): - The limit is stored in the JSRegExp's data array. - A limit can currently only be set through the %NewRegExpWithLimit runtime function. - The limit is applied during interpreter execution. When exceeded, the interpreter stops execution and returns FAILURE (even if continued execution would at some later point have resulted in SUCCESS). In follow-up CLs, this mechanism will be extended to work in jitted regexp code, and exposed through the V8 API.

The tier-up check is only needed for instances that currently go through the interpreter. It is simpler to move the check into the interpreter's C++ entry point. At that point, when we see a JSRegExp that should tier-up, we simply return RETRY which will automatically send us back into runtime where the actual recompilation happens.

Bytecodes used by the regular expression interpreter often occur in specific sequences. The number of dispatches in the interpreter can be reduced if those sequences are combined into a single bytecode. This CL adds a peephole optimization pass for regexp bytecodes. This pass checks the generated bytecode for pre-defined sequences that can be merged into a single bytecode. With the currently implemented bytecode sequences a speedup of 1.12x on regex-dna and octane-regexp is achieved.

The code fields in a JSRegExp object now either contain irregexp compiled code or a trampoline to the interpreter. This way the code can be executed without explicitly checking if the regexp shall be interpreted or executed natively. In case of interpreted regexp the generated bytecode is now stored in its own fields instead of the code fields for Latin1 and UC16 respectively. The signatures of the jitted irregexp match and the regexp interpreter have been equalized.

Printing regexp code used to behind the generic --print-code flag, but there was no way to distinguish between irregexp-generated code; and printing regexp bytecode was not supported at all (the --trace-regexp-bytecodes flag *did* exist, but prints the execution trace at runtime and not the generated bytecode sequence). This CL adds two new flags: --print-regexp-code --print-regexp-bytecode Regexp code is no longer printed as part of --print-code.

This CL implements a naive tiering-up strategy where the interpreter is used for the first execution for every regex, and the compiler is used for every execution after that. The only exception is if a global replace is being executed on a regex, we eagerly tier-up to native code right away. To use the tier-up logic --regexp-tier-up needs to be set. It is currently disabled by default. Bug v8:9566 Change-Id: Ib64ed77cbfcde10411161c0541dfa2501a0a93bd Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/1710661Reviewed-by:

This issue was raised by Brett Wilson while reviewing my changelist for readability. Craig Silverstein (one of C++ SG maintainers) confirmed that we should declare one namespace per line. Our way of namespaces closing seems not violating style guides (there is no clear agreement on it), so I left it intact.

never have to convert an ASCII string to UC16 for Irregexp. * Generate slightly different code when we know the subject string is ASCII. Review URL: http://codereview.chromium.org/13247 git-svn-id: http://v8.googlecode.com/svn/branches/bleeding_edge@941 ce2b1a6d-e550-0410-aec6-3dcde31c8c00

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

Added a few samples and support for building them. The samples include a simple shell that can be used to benchmark and test V8. Changed V8::GetVersion to return the version as a string. Added source for lazily loaded scripts to snapshots and made serialization non-destructive. Improved ARM support by fixing the write barrier code to use aligned loads and stores and by removing premature locals optimization that relied on broken support for callee-saved registers (removed). Refactored the code for marking live objects during garbage collection and the code for allocating objects in paged spaces. Introduced an abstraction for the map word of a heap-allocated object and changed the memory allocator to allocate executable memory only for spaces that may contain code objects. Moved StringBuilder to utils.h and ScopedLock to platform.h, where they can be used by debugging and logging modules. Added thread-safe message queues for dealing with debugger events. Fixed the source code reported by toString for certain builtin empty functions and made sure that the prototype property of a function is enumerable. Improved performance of converting values to condition flags in generated code. Merged disassembler-{arch} files. git-svn-id: http://v8.googlecode.com/svn/trunk@8 ce2b1a6d-e550-0410-aec6-3dcde31c8c00
