[jochen (gone - plz use gerrit), 2016-04-28 10:31:25]

when I apply this patch, e.g. the mksnapshot.cc file still is not compiled with
-DCAN_USE_NEON.

Any idea why this is?

File BUILD.gn (right):

https://codereview.chromium.org/1927893002/diff/20001/BUILD.gn#newcode222
BUILD.gn:222: defines += [ "__mips_hard_float=0" ]
In toolchain.gypi there is __mips_soft_float=1

https://codereview.chromium.org/1927893002/diff/20001/BUILD.gn#newcode232
BUILD.gn:232: "_MIPS_ARCH_MIPS32R2",
maybe pull the three _MIPS_ARCH_MIPS32R2 defines one scope up?
