+#define __ARM_ARCH__ __LINUX_ARM_ARCH__
+@ ====================================================================
+@ Written by Andy Polyakov <appro@fy.chalmers.se> for the OpenSSL
+@ project. The module is, however, dual licensed under OpenSSL and
+@ CRYPTOGAMS licenses depending on where you obtain it. For further
+@ details see http://www.openssl.org/~appro/cryptogams/.
+@ ====================================================================
+
+@ sha1_block procedure for ARMv4.
+@
+@ January 2007.

+@ Size/performance trade-off
+@ ====================================================================
+@ impl		size in bytes	comp cycles[*]	measured performance
+@ ====================================================================
+@ thumb		304		3212		4420
+@ armv4-small	392/+29%	1958/+64%	2250/+96%
+@ armv4-compact	740/+89%	1552/+26%	1840/+22%
+@ armv4-large	1420/+92%	1307/+19%	1370/+34%[***]
+@ full unroll	~5100/+260%	~1260/+4%	~1300/+5%
+@ ====================================================================
+@ thumb		= same as 'small' but in Thumb instructions[**] and
+@		  with recurring code in two private functions;
+@ small		= detached Xload/update, loops are folded;
+@ compact	= detached Xload/update, 5x unroll;
+@ large		= interleaved Xload/update, 5x unroll;
+@ full unroll	= interleaved Xload/update, full unroll, estimated[!];
+@
+@ [*]	Manually counted instructions in "grand" loop body. Measured
+@	performance is affected by prologue and epilogue overhead,
+@	i-cache availability, branch penalties, etc.
+@ [**]	While each Thumb instruction is twice smaller, they are not as
+@	diverse as ARM ones: e.g., there are only two arithmetic
+@	instructions with 3 arguments, no [fixed] rotate, addressing
+@	modes are limited. As result it takes more instructions to do
+@	the same job in Thumb, therefore the code is never twice as
+@	small and always slower.
+@ [***]	which is also ~35% better than compiler generated code. Dual-
+@	issue Cortex A8 core was measured to process input block in
+@	~990 cycles.
+
+@ August 2010.
+@
+@ Rescheduling for dual-issue pipeline resulted in 13% improvement on
+@ Cortex A8 core and in absolute terms ~870 cycles per input block
+@ [or 13.6 cycles per byte].
+
+@ February 2011.
+@
+@ Profiler-assisted and platform-specific optimization resulted in 10%
+@ improvement on Cortex A8 core and 12.2 cycles per byte.
