544889 - [buildbot] Add device testing of VFP on ARM hardware

Status: VERIFIED FIXED

(Tamarin Graveyard :: Build Config, defect, P2)

Description

[Brent Baker]

Currently buildbot is only running acceptance suite on Windows Mobile in emulation and this configuration does not support VFP. We need to add device hardware running the acceptance suite to buildbot so that we can test the shell compiled with arm-fpu and use the runtime switch to enable VFP support in the jit (-Darm_vfp)

Windows Mobile Emulator: 
- the emulator only supports up to ARMv5, however we require ARMv6+ to compile in fpu support

Attachment: WinMo device acceptance script

- add a generic acceptance script that will deploy the shell on the windows mobile device and run the acceptance suite
- this requires that the device is setup properly based on documentation in utils/wmremote/readme.txt

[Trevor Baker]

can we do this testing on a beagleboard?

Comment 4

[Brent Baker]

Added arm-linux into the build system
- compiled with NEON vfp support (-mfpu=neon -march=armv7-a)

Running the following acceptance passes:
release hybrid softfloat (default config)
release hybrid VFP (-Darm_arch 7 -Darm_vfp)
release interp
release jit VFP (-Darm_arch 7 -Darm_vfp)
debug hybrid VFP (-Darm_arch 7 -Darm_vfp)
