Suppress array bounds check for nacl build. · 1d1b8467

machenbach@chromium.org authored Jul 10, 2013

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.

Change DataView accessors behavior for insufficient args. · 5eb63e48

dslomov@chromium.org authored Jul 10, 2013

ES6 spec for DataView is not fully finished, but Blink, WebKit and
Firefox agree in that for DataView use of getters/setters with no
arguments should result in exceptions, while undefined offset argument
is the same as zero.

Enable debug builds with some optimizations turned on. · dfd955ff

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.

MIPS: Adjust default Heap sizes. · 7c8883f3

palfia@homejinni.com authored Jul 10, 2013

This change decreases the default Heap sizes on MIPS (sets the
same sizes as on Android).

Most MIPS hw has smaller RAM size than 700MB, which can lead
to test failures, if a test does not set the  Heap sizes explicitly
(like cctest/test-mark-compact/MarkCompactCollector).
