IIRC .syntax should not affect the fp ABI assumptions, Its plainly for = unifying arm/thumb-ness in asm files and .eabi_attribute is the directive which could set FP ABI = and I don=E2=80=99t see it being set in asm file which means it will be set depending on compiler = cmdline. > I'd really like some feedback on what the issues > with that are and how to best avoid problems.
