Assembler Testcases
===================
@ -7,7 +6,7 @@ Opcode Tests:
These testcases are inspired by the ones now removed from test/assembler.
The main purpose is to have each possible opcode generated at least once,
either by an assembly instruction or a ".byte"-placeholder. Typically

CPU Detect Tests
----------------
These tests all assemble the same file "cpudetect.s" which contains several
conditionals for several CPUs, only using every option known to the "--cpu"

Reference (".ref") Files
------------------------
A hint on creating these files: when running the test, it will fail due to
the missing ".ref" file. Review the output of the ".lst" very pedantic, then
copy the ".bin" to the ".ref" file.
Some hints about creating new files:
Make an empty file with the CPU's name prepended to "-cpudetect.ref". Run the
tests; one of them will fail due to a mismatch. Review the output of the
".lst" file pedantically, then copy the ".bin" over the empty ".ref" file.
