There are at least two neon subdirs under mpn/arm.
I see one file that looks interesting (lshiftc.asm):
$ ls mpn/arm/neon/
README lorrshift.asm sec_tabselect.asm
hamdist.asm lshiftc.asm popcount.asm
Does this look about right:
# mpn/arm/neon/lshiftc.asm
...
ASM_START()
TEXT
ALIGN(64)
.fpu neon
PROLOGUE(mpn_lshiftc)
IFLSH(` mov r12, n, lsl #2 ')
IFLSH(` add rp, rp, r12 ')
IFLSH(` add ap, ap, r12 ')
I think this is perhaps not as clean as one would want it to be.
Perhaps add a parameter to ASM_START, or add a new macro which could be
made empty for machines which do not need or accept the new directive.
(About your error: Your adting the lshiftc.asm file. Note the c at the
end. Wrong file.)
