V8 requires ARMv6 and VFPv2 as a minimum.

[v8-users] Problem building V8 (v6.1.534) on armv5TEJ without VFP/Neon

2017-12-11 Thread ttran . pcs 
Hello everyone,

Currently i am trying to build V8 (v6.1.534) on ARM926EJ-S ( armv5TEJ 
without VFP nor NEON) with the current config
"./tools/cross_build_gcc.sh 
/home/crossdev/arm-none-linux-gnueabi/bin/arm-none-linux-gnueabi- arm.debug 
arm_version=5 armfloatabi=softfp armfpu=default armthumb=on backtrace=on 
debugsymbols=on gdbjit=on"

"amfloatabi" should be "soft", however, from the Makefile there are only 2 
possible solution: hard and softfp [line 207:/v8/Makefile].
During the building, i keep getting error "#error 
"CAN_USE_ARMV7_INSTRUCTIONS should match CAN_USE_VFP3_INSTRUCTIONS"  [line 
176:/v8/src/arm/assembler-arm.cc]
I tried different options but it doesn't help.
I dig deeper into the source codes and it seems to me that V8 engine only 
support armv6, armv7 and armv8 (need either VFP or NEON)   [line 
58:/v8/src/arm/assembler-arm.cc] and [line 200:/v8/Makefile].

My question is: does V8 Engine support armv5 and does it need VFP or NEON 
to work?

Thank you.
Thang Tran
