The following defconfig:
BR2_powerpc64=y
BR2_powerpc_power8=y
fails to build on my machine, with the same error:
/tmp/ccZgjbrm.s: Assembler messages:
/tmp/ccZgjbrm.s:19: Error: operand out of domain (7 is not a multiple of 2)
Here is the offending assembly file:
.file "exch_n.c"
.section ".toc","aw"
.section ".text"
.align 2
.globl libat_exchange_16
.hidden libat_exchange_16
.section ".opd","aw"
.align 3
libat_exchange_16:
.quad .L.libat_exchange_16,.TOC. at tocbase,0
.previous
.type libat_exchange_16, @function
.L.libat_exchange_16:
sync
mr 9,3
mr 11,5
mr 10,4
.L2:
lqarx 7,0,9
mr 3,7
mr 4,8
stqcx. 10,0,9
bne- 0,.L2
isync
blr
.long 0
.byte 0,0,0,0,0,0,0,0
.size libat_exchange_16,.-.L.libat_exchange_16
.globl __atomic_exchange_16
.set __atomic_exchange_16,libat_exchange_16
.ident "GCC: (Buildroot 2016.02-git-00995-g390d559) 4.9.3"
So the instruction "lqarx 7,0,9" is at fault.
Best regards,
Thomas
