+! C run time start off
+
+! This file supports:
+!
+! - both 32bit pointer and 64bit pointer environments (at compile time)
+! - an imposed stack bias (of 2047) (at run time)
+! - medium/low and medium/anywhere code models (at run time)
+
+! Initial stack setup:
+!
+!    bottom of stack (higher memory address)
+! 	...
+!	text of environment strings
+!	text of argument strings
+!	envp[envc] = 0 (4/8 bytes)
+!	...
+!	env[0] (4/8 bytes)
+!	argv[argc] = 0 (4/8 bytes)
+!	...
+!	argv[0] (4/8 bytes)
+!	argc (4/8 bytes)
+!	register save area (64 bits by 16 registers = 128 bytes)
+!	top of stack (%sp)
+
+! Stack Bias:
+!
+! It is the responsibility of the o/s to set this up.
+! We handle both a 0 and 2047 value for the stack bias.
+
+! Medium/Anywhere code model support:
+!
+! In this model %g4 points to the start of the data segment.
+! The text segment can go anywhere, but %g4 points to the *data* segment.
+! It is up to the compiler/linker to get this right.
+!
+! Since this model is statically linked the start of the data segment
+! is known at link time.  Eg:
+!
+!	sethi	%hh(data_start), %g1
+!	sethi	%lm(data_start), %g4
+!	or	%g1, %hm(data_start), %g1
+!	or	%g4, %lo(data_start), %g4
