Marja Hölttä [Tue, 2 Dec 2014 13:23:30 +0000 (14:23 +0100)]

Make the ParserSync test faster (and re-enable it).

Most of the run time came from testing with all possible flag combinations. None
of the flags passed affect the test, and there are specialized tests for testing
the features behind the flags; no need to slow down the generic test.

With these changes, run time for debug build goes from 186 s to 0.5 s.

In addition, fixed some missing commas between the test cases.

Set V8_CC_GNU or V8_CC_MSVC for clang in gcc / cl mode.

Also, remove V8_CC_CLANG since it's not read anywhere (and ideally shouldn't
be).

Clang tries to be compatible with gcc in clang mode, and with msvc in clang-cl
mode. It wants to go down the same code paths that these compilers want to go
down in most cases.

For example, V8PRIxPTR was set incorrectly on Windows 64-bit before this change
since macros.h assumed that checking for V8_CC_MSVC is enough to find LLP64
systems, but V8_CC_MSVC wasn't set for clang. Most other existing checks for
V8_CC_MSVC should be taken for clang-cl too (and for the remaining ones,
clang-cl is happy with either code path).

Likewise, V8_IMMEDIATE_CRASH is currently set to a suboptimal value with clang
since __builtin_trap() is only used if V8_CC_GNU is set.

Including clang in the gcc and cl macros is also what chromium does.

Make TemplateLiteral hashing algorithm more memory efficient

Previously, a separate string to be hashed (in order to help determine the need to
use a cached Template Call Site) was built up by joining UTF8 spans within a template.

Now, the hash key is generated from the original spans, removing the need to allocate a new
buffer and copy bytes into it.

Abort optimization in corner case.

The %OptimizeFunctionOnNextCall sledgehammer can cause a function to be
marked for optimization before it's ever been compiled by fullcode.
This can lead to the situation where a function doesn't have optimization
disabled until we try to compile it optimized.

Basically, the assert should just handle this case more gracefully.
