This in turn means that *sum* + @ of the products with these values can still be viewed as sum + @ of 52-bit numbers as long as the amount of addends is not a + @ power of 2. For example, + @ + @ H4 = H4*R0 + H3*R1 + H2*R2 + H1*R3 + H0 * R4, + @ + @ which can't be larger than 5 * (2^26 + 2^6) * (2^26 + 2^6), or + @ 5 * (2^52 + 2*2^32 + 2^12), which in turn is smaller than + @ 8 * (2^52) or 2^55. However, the value is then multiplied by + @ by 5, so we should be looking at 5 * 5 * (2^52 + 2^33 + 2^12), + @ which is less than 32 * (2^52) or 2^57.

How is this relevant? vmlal.u32 + @ instruction accepts 2x32-bit input and writes 2x64-bit result. + @ This means that result of reduction have to be compressed upon + @ loop wrap-around. This can be done in the process of reduction + @ to minimize amount of instructions [as well as amount of + @ 128-bit instructions, which benefits low-end processors], but + @ one has to watch for H2 (which is narrower than H0) and 5*H4 + @ not being wider than 58 bits, so that result of right shift + @ by 26 bits fits in 32 bits.

This in turn means that *sum* + @ of the products with these values can still be viewed as sum + @ of 52-bit numbers as long as the amount of addends is not a + @ power of 2. For example, + @ + @ H4 = H4*R0 + H3*R1 + H2*R2 + H1*R3 + H0 * R4, + @ + @ which can't be larger than 5 * (2^26 + 2^6) * (2^26 + 2^6), or + @ 5 * (2^52 + 2*2^32 + 2^12), which in turn is smaller than + @ 8 * (2^52) or 2^55. However, the value is then multiplied by + @ by 5, so we should be looking at 5 * 5 * (2^52 + 2^33 + 2^12), + @ which is less than 32 * (2^52) or 2^57. And when processing + @ data we are looking at triple as many addends... + @ + @ In key setup procedure pre-reduced H0 is limited by 5*4+1 and + @ 5*H4 - by 5*5 52-bit addends, or 57 bits. But when hashing the + @ input H0 is limited by (5*4+1)*3 addends, or 58 bits, while + @ 5*H4 by 5*5*3, or 59[!] bits. How is this relevant? vmlal.u32 + @ instruction accepts 2x32-bit input and writes 2x64-bit result. + @ This means that result of reduction have to be compressed upon + @ loop wrap-around. This can be done in the process of reduction + @ to minimize amount of instructions [as well as amount of + @ 128-bit instructions, which benefits low-end processors], but + @ one has to watch for H2 (which is narrower than H0) and 5*H4 + @ not being wider than 58 bits, so that result of right shift + @ by 26 bits fits in 32 bits. This is also useful on x86, + @ because it allows to use paddd in place for paddq, which + @ benefits Atom, where paddq is ridiculously slow. + + vshr.u64 q15,q8,#26 + vmovn.i64 d16,q8 + vshr.u64 q4,q5,#26 + vmovn.i64 d10,q5 + vadd.i64 q9,q9,q15 @ h3 -> h4 + vbic.i32 d16,#0xfc000000 @ &=0x03ffffff + vadd.i64 q6,q6,q4 @ h0 -> h1 + vbic.i32 d10,#0xfc000000 + + vshrn.u64 d30,q9,#26 + vmovn.i64 d18,q9 + vshr.u64 q4,q6,#26 + vmovn.i64 d12,q6 + vadd.i64 q7,q7,q4 @ h1 -> h2 + vbic.i32 d18,#0xfc000000 + vbic.i32 d12,#0xfc000000 + + vadd.i32 d10,d10,d30 + vshl.u32 d30,d30,#2 + vshrn.u64 d8,q7,#26 + vmovn.i64 d14,q7 + vadd.i32 d10,d10,d30 @ h4 -> h0 + vadd.i32 d16,d16,d8 @ h2 -> h3 + vbic.i32 d14,#0xfc000000 + + vshr.u32 d30,d10,#26 + vbic.i32 d10,#0xfc000000 + vshr.u32 d8,d16,#26 + vbic.i32 d16,#0xfc000000 + vadd.i32 d12,d12,d30 @ h0 -> h1 + vadd.i32 d18,d18,d8 @ h3 -> h4 + + subs r5,r5,#1 + beq .Lsquare_break_neon + + add r6,r0,#(48+0*9*4) + add r7,r0,#(48+1*9*4) + + vtrn.32 d0,d10 @ r^2:r^1 + vtrn.32 d3,d14 + vtrn.32 d5,d16 + vtrn.32 d1,d12 + vtrn.32 d7,d18 + + vshl.u32 d4,d3,#2 @ *5 + vshl.u32 d6,d5,#2 + vshl.u32 d2,d1,#2 + vshl.u32 d8,d7,#2 + vadd.i32 d4,d4,d3 + vadd.i32 d2,d2,d1 + vadd.i32 d6,d6,d5 + vadd.i32 d8,d8,d7 + + vst4.32 {d0[0],d1[0],d2[0],d3[0]},[r6]! + vst4.32 {d0[1],d1[1],d2[1],d3[1]},[r7]! + vst4.32 {d4[0],d5[0],d6[0],d7[0]},[r6]! + vst4.32 {d4[1],d5[1],d6[1],d7[1]},[r7]! + vst1.32 {d8[0]},[r6,:32] + vst1.32 {d8[1]},[r7,:32] + + b .Lsquare_neon + +.align 4 +.Lsquare_break_neon: + add r6,r0,#(48+2*4*9) + add r7,r0,#(48+3*4*9) + + vmov d0,d10 @ r^4:r^3 + vshl.u32 d2,d12,#2 @ *5 + vmov d1,d12 + vshl.u32 d4,d14,#2 + vmov d3,d14 + vshl.u32 d6,d16,#2 + vmov d5,d16 + vshl.u32 d8,d18,#2 + vmov d7,d18 + vadd.i32 d2,d2,d12 + vadd.i32 d4,d4,d14 + vadd.i32 d6,d6,d16 + vadd.i32 d8,d8,d18 + + vst4.32 {d0[0],d1[0],d2[0],d3[0]},[r6]! + vst4.32 {d0[1],d1[1],d2[1],d3[1]},[r7]! + vst4.32 {d4[0],d5[0],d6[0],d7[0]},[r6]! + vst4.32 {d4[1],d5[1],d6[1],d7[1]},[r7]! + vst1.32 {d8[0]},[r6] + vst1.32 {d8[1]},[r7] + +.Lno_init_neon: + bx lr @ bx lr +.size poly1305_init_neon,.-poly1305_init_neon + +.type poly1305_blocks_neon,%function +.align 5 +poly1305_blocks_neon: +.Lpoly1305_blocks_neon: + ldr ip,[r0,#36] @ is_base2_26 + + cmp r2,#64 + blo .Lpoly1305_blocks + + stmdb sp!,{r4-r7} + vstmdb sp!,{d8-d15} @ ABI specification says so + + tst ip,ip @ is_base2_26?
