-<h3>Synopsis</h3>
-<b>NestedCall.tst</b> is an intermediate test (in terms of complexity) intended to be used between the SimpleFunction and
-FibonacciElement tests. It may be useful when SimpleFunction passes but FibonacciElement fails or crashes. NestedCall also
-tests several requirements of the Function Calling Protocol that are not verified by the other
-supplied tests. NestedCall can be used with or without the VM bootstrap code.
-<p>
-<b>NestedCallVME.tst</b> runs the same test on the VM Emulator.
-<p>
-<b>The NestedCall</b> tests and supporting documentation were written by Mark Armbrust.
-
-<!-- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -->
-<h3>Test Structure</h3>
-<h4>Startup</h4>
-NestedCall is implemented entirely within the Sys.vm file. The first function in Sys.vm is
-Sys.init(). This allows it to be used before the bootstrap code has been added to the VM Translator
-since there will be no file processing order issues.
-<p>
-NestedCall loads Sys.asm, sets up the stack to simulate the bootstrap's call to Sys.init(), then
-begins execution at the beginning of Sys.asm. If the bootstrap is not present, the program begins
-running with Sys.init() since it is the first function in Sys.vm.
-<p>
-If Sys.asm includes the bootstrap, the bootstrap will (re)initialize the stack and call Sys.init(),
-so the test should see the same environment either way it gets to Sys.init().
-<p>
-The test setup also initializes the
-
-<h4>Sys.init()</h4>
-
-<span class="code">THIS</span> and <span class="code">THAT</span> are set to known values so that context save and restore can be tested.
-<p>
-Sys.init() calls Sys.main() and stores the return value in <span class="code">temp 1</span>. This tests call to and
-return from a function with no arguments.
-
-<h4>Sys.main()</h4>
-Sys.init() allocates 5 local variables. It sets <span class="code">local 1</span>, <span class="code">local 2</span> and
-<span class="code">local 3</span>. <span class="code">local 0</span> and <span class="code">local 4</span> are intentionally not set.
-<p>
-<span class="code">THIS</span> and <span class="code">THAT</span> are changed so that context save and restore can be tested.
-<p>
-Sys.main() calls Sys.add12(123) and stores the return value in <span class="code">temp 0</span>. This tests call to and
-return from a function with arguments.
-<p>
-After Sys.add12() returns, Sys.main() sums <span class="code">local 0</span> through <span class="code">local 4</span> and returns the
-result. This tests that the local segment was properly allocated on the stack and that the local
-variables were not overwritten by the call to Sys.main(). It also tests that <span class="code">local 0</span> and
-<span class="code">local 4</span> were properly initialized to 0.
-
-<h4>Sys.add12()</h4>
-
-<span class="code">THIS</span> and <span class="code">THAT</span> are set to known values so that context save and restore can be tested.
-<p>
-Returns <span class="code">argument 0</span> plus 12.

-<h3>Test Coverage</h3>
-
-<p style="margin-left:1em; text-indent:-1em;">
-Functions with no arguments return to correct RIP (Return Instruction Point) with correct return value on stack.<br>
-This can fail if the RIP is not correctly pushed on the stack by the calling code, or if the returning
-code does not store the RIP in a temporary register before overwriting it with the return value.
-
-<p style="margin-left:1em; text-indent:-1em;">
-Functions with arguments return to correct RIP with correct return value on stack.<br>
-This can fail if it is assumed that <span class="code">ARG</span> points to the RIP.
-
-<p style="margin-left:1em; text-indent:-1em;">
-Functions with local variables allocate space on the stack for the local variables.<br>
-This can fail if the function prologue is not written or if the SP is not updated after zeroing
-the local variables.
-
-<p style="margin-left:1em; text-indent:-1em;">
-All local variables are initialized to 0.<br>
-Common errors are to forget this completely, or for the zeroing loop to be off by one.
-
-<p style="margin-left:1em; text-indent:-1em;">
-<span class="code">THIS</span> and <span class="code">THAT</span> are correctly retained across function calls. Looking ahead, in Project 9 you will be asked to write a simple computer game in the high-level Jack language. You can run your game (following compilation) on the supplied VM Emulator. But, if you choose to translate the VM code that the compiler generates using <em>your</em> VM Translator, then code like
-"<span class="code">push THIS</span>, <span class="code">push THAT</span> ... <span class="code">pop THIS</span>, <span class="code">pop THAT</span>" can cause some interesting failures!
-
-<!-- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -->
-<h3>Debugging</h3>
-These comments assume that your VM translator has passed the SimpleFunction test.
-<p>
-If <span class="code">RAM[0]</span> is incorrect, you have a stack skew. More data was pushed onto the stack by
-<span class="code">call</span> than was popped by <span class="code">return</span>, or vice versa. See <i>debugging with
-breakpoints</i> later in this section.
-<p>
-If one or more of <span class="code">RAM[1]</span> through <span class="code">RAM[4]</span> is incorrect, the <span class="code">LCL</span>,
-<span class="code">ARG</span>, <span class="code">THIS</span> and <span class="code">THAT</span> pointers are not being correctly saved or restored.
-Most likely problem is when they are being saved; the SimpleFunction test verified that
-<span class="code">return</span> restored them correctly.
-<p>
-If <span class="code">RAM[5]</span> is incorrect there may be a problem with setting up the <span class="code">ARG</span> pointer.
-<p>
-If <span class="code">RAM[4]</span> is incorrect and <span class="code">RAM[5]</span> is correct, there may be a problem with
-allocation or initialization of local variables.
-
-<h4>Debugging with breakpoints</h4>
-
-To find tough bugs you can use the "breakpoint" facility in the CPU Emulator (red flag button).
-You can use breakpoints to have you program stop when it gets to a particular RAM address. For
-example:<br>
-&emsp;&bull;&ensp;load the NestedCall.tst file,<br>
-&emsp;&bull;&ensp;set a PC breakpoint at the ROM address for <span class="code">(Sys.main)</span>,<br>
-&emsp;&bull;&ensp;hit the run button.<br>
-When the CPU Emulator stops at the breakpoint you can inspect the RAM to check the stack and pointers values.
-(If the breakpoint isn't hit, you will need to to single-step debug through
-your calling code to see why it didn't get there.)
-<p>
-Other useful places to set breakpoints are the entry points to the other functions and at the
-first and final instructions generated for <span class="code">return</span> commands.
-<p>
-<a href="NestedCallStack.html">NestedCallStack.html</a> shows the expected stack values at various points
-during the test.
-
-<h4>Finding ROM address in your ASM code</h4>
-It is not easy to find the ROM locations where you want to set breakpoints, because there is no
-one-to-one correspondence between the ASM file line numbers and the ROM addresses. This is made even more
-difficult because the supplied CPU Emulator does not display the (LABELS) in its ROM panel.
-<p>
-There are two things that you can do to make this easier.
-<p>
-<h5>Modify your assembler to generate a listing file.</h5>
-A listing file shows all the ASM source lines, including comments, as well as the ROM addresses and
-the values of the labels and the instructions. For example, here is a snippet of a listing file generated by an assembler written by Mark Armbrust:
-<pre>
- 20 16 @i // i -= 1
- 21 FC88 M=M-1
-
- 22 FC10 D=M // if i > 0
- 23 6 @LOOP
- 24 E301 D;JGT // goto LOOP
-
- 25 (STOP)
- 25 25 @STOP
- 26 EA87 0;JMP
-
-Data Symbols
-
- 16 D i
-
-Code Symbols
-
- 6 C LOOP
- 17 C SKIP
- 25 C STOP
-</pre>
-For the Nand2Tetris environment, it is most useful to list the ROM addresses and A-instruction
-values in decimal. In the above snippet, the C-instruction values are
-listed in hexadecimal.
-<p>
-The list file is generated during pass 2 of the Assembler, parallel to generating the .hack file. To
-make it easier to handle blank and comment only lines, Mark has Parser.commandType() return
-NO_COMMAND for source lines with no command. Mark also added Parser.sourceLine() that returns the
-unmodified source line.
-<p>
-<h5>Have your VM Translator write the VM source lines as comments in the ASM output.</h5>
-For example:
-<pre>
- // label LOOP
-(Sys.init$LOOP)
- // goto LOOP
-@Sys.init$LOOP
-0;JMP
- //
- // // Sys.main()
- //
- // // Sets locals 1, 2 and 3, leaving locals 0 and 4 unchanged to test
- // // default local initialization to 0. (RAM set to -1 by test setup.)
- // // Calls Sys.add12(123) and stores return value (135) in temp 0.
- // // Returns local 0 + local 1 + local 2 + local 3 + local 4 (456) to confirm
- // // that locals were not mangled by function call.
- //
- // function Sys.main 5
-(Sys.main)
-@5
-D=-A
-($3)
-@SP
-</pre>
-Note that comments in the VM source become double comments. Looking ahead, in Project 11 you will be asked to write a compiler for the Jack language. If your compiler will write the Jack source lines as comments in the
-generated VM files, this convention will be quite useful.
