Friday’s lecture again

Using E-TDD environment Build the tests you want to pass Build the code Test the code

Using E-TDD environment Using the C++ tests, build the ASM tests (cut and paste is all that is needed) Build the ASM stubs (Makes sure that you can load the load into the processor Test the code stub – program will run but fail the tests as only stubs Build the code Test the code

Build the stub 1 Find the name mangling needed Just build the code VDSP will tell you the necessary name- mangled names Cut and paste the names

Build the stub 2

Expect error messages But not these ones Code review Missing a ; at end of line

Need to learn to READ And listen to assembler That semicolon is not the one that was missing There is one semicolon too many in the define statement

Less errors But I am still not listening to the assembler

Look on reference sheet R0 *= R1; Page 2, column 3

Assembled But failed tests What of GS is happening

Build the ASM test by cut-and-paste

Stubs assemble But unexpected messages

Build the ASM test by cut-and-paste CORRECTLY

Wrong method Incoming parameters – come in R0 Outgoing parameters – go in R0 Return values – go in R0 Same problem on the MIPS
