New binutils (since 2.27.51) cannot build musl-1.1.16 due to breakage in ARMv4 atomics asm. This patch from upstream musl repository is needed until musl-1.1.17 is released: https://git.musl-libc.org/cgit/musl/commit/?id=b261a24256792177a5f0531dbb25cc6267220ca5 Signed-off-by: Timothy Lee <timothy.ty.lee@gmail.com> Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>

Subject: fix build regression in arm atomics asm with new binutils
|
|
|
|
binutils commit bada43421274615d0d5f629a61a60b7daa71bc15 tightened
|
|
immediate fixup handling in gas in such a way that the final .arch of
|
|
an object file must be compatible with the fixups used when the
|
|
instruction was assembled; this in turn broke assembling of atomics.s,
|
|
at least in thumb mode.
|
|
|
|
it's not clear whether this should be considered a bug in gas, but
|
|
.object_arch is preferable anyway for our purpose here of controlling
|
|
the ISA level tag on the object file being produced, and it's the
|
|
intended directive for use in object files with runtime code
|
|
selection. research by Szabolcs Nagy confirmed that .object_arch is
|
|
supported in all relevant versions of binutils and clang's integrated
|
|
assembler.
|
|
|
|
