17c2a7a5ed MIPS: update missing write barrier for arguments store ICs, per comments.
Per review comments in http://codereview.chromium.org/7238020 after
issue was closed, we had used an un-necessary Add, which is removed here.
Thanks for the suggestion.

3b2470d296 Fix presubmit errors catched by a more recent version of cpplint.py.
Mainly, there were errors concerning blank lines before and after class access
control sections [whitespace/blank_line].

BEFORE an access control section (e.g. public:, private:) there should be a
blank line (except for the section right after the class declaration).

AFTER an access control section there should be no blank line.

64c610727d MIPS: Added the stop() instruction with same behavior as on Arm simulator.
The already working watchpoint break mechanism has been extended to handle "stop" instructions, with text messages.

Explanation (also in constants-mips.h):
On MIPS Simulator breakpoints can have different codes:
- Breaks between 0 and kMaxWatchpointCode are treated as simple watchpoints, the simulator will run through them and print the registers.
- Breaks between kMaxWatchpointCode and kMaxStopCode are treated as stop() instructions (see Assembler::stop()).
- Breaks larger than kMaxStopCode are simple breaks, dropping you into the debugger.

The current values are 31 for kMaxWatchpointCode and 127 for kMaxStopCode.
From the user's point of view this works the same way as the ARM stop instruction except for the break code usage detailed above.

2531480d10 Re-establish mips basic infrastructure.
This commit adds current working versions of assembler, macro-assembler,
disassembler, and simulator.

All other mips arch files are replaced with stubbed-out versions that
will build.

Arch independent files are updated as needed to support building and
running mips.

The only test is cctest/test-assembler-mips, and this passes on the
simulator and on mips hardware.

9c503a8330 Fix some inconsistent formatting.
I noticed we sometimes had extra spaces before and after the "const"
keyword.  Probably the result of a search and replace gone wrong.

This is a whitespace only change.

634fb9152c More precise break points and stepping when debugging
Added support for more precise break points when debugging and stepping. To achieve that additional nop instructions are inserted where breaking would otherwise be impossible. The number of nop instructions inserted are sufficient to make place for patching with a call to a debug break code stub. On Intel that is 5 nop's for 32-bit and 13 for 64-bit. Om ARM 3 nop instructions (12 bytes) are required.

In order to avoid inserting nop's in to many places a simple ast checker have been added to check whether there are breakable code in a statement or expression. If it is possible to break in an expression no additional break enabeling code is inserted.

Added break locations to the true and false part of a conditional expression.

Added stepping tests to cover more constructs.

These changes are only in the full compiler.

Changed the default value for the option --debugger in teh d8 shell from true to false. The reason for this is that with --debugger turned on the full compiler will be used for all code in when running d8, which can be unexpeceted.

5c7ffe9f1c Return the correct statement position.
Whether this was a typo or a deliberate decision at some point I don't know. Anyway it was wrong.

a6a7c75ae0 MIPS port initial commit
This is the first step in the MIPS port of V8. It adds assembler, disassembler and simulator for the MIPS32 architecture.

Contains stubbed out implementation of all the compiler/code generator infrastructure to make it all build.
