# Poly1305 - this version mainly using vector/VSX/Scalar
# - 26 bits limbs
# - Handle multiple 64 byte blcoks but need at least 2 64 bytes block
#
# Improve performance by breaking down polynominal to the sum of products with
# h4 = m1 * r⁴ + m2 * r³ + m3 * r² + m4 * r
#
# 07/22/21 - this revison based on the above sum of products. Setup r^4, r^3, r^2, r and s3, s2, s1, s0
# to 9 vectors for multiplications.
#
# setup r^4, r^3, r^2, r vectors
# vs [r^1, r^3, r^2, r^4]
# vs0 = [r0,.....]
# vs1 = [r1,.....]
# vs2 = [r2,.....]
# vs3 = [r3,.....]
# vs4 = [r4,.....]
# vs5 = [r1*5,...]
# vs6 = [r2*5,...]
# vs7 = [r2*5,...]
# vs8 = [r4*5,...]

# Taken from mpfr-4.0.1, then modified for LDADD_FOR_TESTS_KLUDGE
dnl Under Linux, make sure that the old dtags are used if LD_LIBRARY_PATH
dnl is defined. The issue is that with the new dtags, LD_LIBRARY_PATH has
dnl the precedence over the run path, so that if a compatible MPFR library
dnl is installed in some directory from $LD_LIBRARY_PATH, then the tested
dnl MPFR library will be this library instead of the MPFR library from the
dnl build tree. Other OS with the same issue might be added later.
