We recently had some XP issues on chromium.win after https://codereview.chromium.org/19384011/.

This might fix it - quote: "The most likely cause of the problem is a gyp (or similar) change that resulted in v8.dll linking against the release version of the crt (for a debug build). There are two MS VC related files: the crt and the c++ std lib (MSVCR100.DLL and MSVCP100D.DLL). The former is set to release, the latter to debug."

I am not entirely sure if this change fits to the linker options for debug level 2.

The change in r15937 might have broken a mozilla test under windows. See https://codereview.chromium.org/19384011/

Each case of debug 0,1,2 is now stated explicitly for better clarity in the msvs section. This causes some minor code duplications, which we can squeeze again after toolchain.gypi is in a stable state.

This patch changes the definition of v8_optimized_debug==1 to match the release-mode compiler optimization settings (generally, going from -O1 to -O3 on Linux, similar switches for Mac/Win). This produces a minor speed up on Linux, but significant speedups on Mac and Win. This may make it much harder to debug, though.

It also adds a v8_optimized_debug==2 that, in addition to the compiler optimizations, undef's DEBUG and defines DEBUG. This leaves V8_ENABLE_CHECKS alone (so that the assertions are still enabled), but otherwise basically matches a release mode build.

Builds with v8_optimized_debug==2 roughly match a Release mode build for speed; the V8_ENABLE_CHECKS checks appear to have minimal performance impact (maybe 5-10%, unlike what was previously thought). In addition, switching from the previous optimization settings makes a significant improvement on Mac and Win (50% or more), and switching from DEBUG to NDEBUG makes a significant improvement (another 50% or more).

Note that using v8_optimized_debug==2 may also cause some v8 tests to fail. This is currently is believed to be acceptable.

The NaCl and the ARM builder started failing to compile at revision 15593 with spurious array bounds warnings.

The ARM builder will be fixed by updating the cross-compiler version. Since the nacl compiler comes with the nacl toolchain, the warning will be suppressed for that builder.

A new gyp variable 'v8_full_debug' can be set to 0 in order to turn on optimization level 1 for debug builds. With the default (=1), it builds in debug mode like before.

The intention is to run some bots on the waterfall with this configuration. Tests have a x5 speed-up like that.

This patch defines new makefile command line paramaters to better control the
ARM specific options. The new paramters are
 * armfpu      = vfp, vfpv3-d16, vfpv3, neon.
 * armfloatabi = softfp, hard
 * armneon     = on
 * armthumb    = on, off
 * armtest     = on
One existing paratemer has been modified:
 * armv7       = true, false
A number of parameters have been deprecated (but are still working):
 * hardfp      = on, off
 * vfp2        = off
 * vfp3        = off

the armtest paratmer when set to "on" will lock the options used during compile
time at runtime. This allows for example to easily test the ARMv6 build on an
ARMv7 platform without having to worry about features detected at runtime. When
not specified the compiler default will be used meaning it is not necessary
anymore to specify hardfp=on when natively building on an hardfp platform.

The shell help now prints the target options and features detected.

Our planned CL for the Chromium build system passes the toolchain
vars though the Makefiles, so that we do not depend on $CXX, etc.,
in the environment.

That causes a problem with deriving the 'm32flag' in v8 gyp.

This patch lets us build with or without the toolchain vars in
the environment.
