+! 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
