------------------------------+---------------------------------------------
The ARM code generator calls llc in the same way regardless of the ABI
being used. When the hardfloat EABI variant is in use - armhf in
Debian/Ubuntu, llc needs to be passed -float-abi=hard.
This may mean the build scripts need to detect armel vs armhf and have a
config option snippet in
compiler/main/DriverPipeline.hs
I made a successful build on armhf by just piggybacking it to check it
works.
else if (elem VFPv3D16 ext)
- then ["-mattr=+v7,+vfp3"]
+ then ["-mattr=+v7,+vfp3,
"-float-abi=hard"]
BTW for Debian/Ubuntu we will need +d16 passed there, but it is not
strictly related to the build failure on armhf.
