armhf build fails in Ubuntu (7.4.1)
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.
