Comment #12 on issue 3112 by [email protected]: v8 goes into SIGILL on
latest Raspbian wheezy
http://code.google.com/p/v8/issues/detail?id=3112
Thanks for pointing me to the new build options. Indeed mine were in our
project from last year.
But this is working pretty strange:
I bukild with:
LINK="/opt/cross/x-tools/arm-unknown-linux-gnueabi/bin/arm-unknown-linux-gnueabi-g++"
LD="/opt/cross/x-tools/arm-unknown-linux-gnueabi/bin/arm-unknown-linux-gnueabi-g++"
make
-C v8 i18nsupport=off library=shared armv7=false hardfp=on
snapshot=off armfpu=vfp armfloatabi=hard arm.debug
And I get this:
target arm v6 vfp2 hard
ARMv7=1 VFP3=0 VFP32DREGS=0 NEON=0 SUDIV=0 UNALIGNED_ACCESSES=1
MOVW_MOVT_IMMEDIATE_LOADS=0 USE_EABI_HARDFLOAT=1
Why ARMv7 is still 1?
By the way, GYP shows during compilation armv7=0:
PYTHONPATH="/home/ps/Desktop/Zwave/Projects/z-way.c/v8-3.22/tools/generate_shim_headers:"
\
GYP_GENERATORS=make \
build/gyp/gyp --generator-output="out" build/all.gyp \
-Ibuild/standalone.gypi --depth=. \
-Dv8_target_arch=arm \
-S.arm -Dcomponent=shared_library -Dv8_enable_backtrace=1
-Dv8_use_snapshot='false' -Dv8_enable_i18n_support=0 -Darmv7=0
-Darm_float_abi=hard -Darm_fpu=vfp -Darm_float_abi=hard
This is the new trace with these build params. The problem is still here:
