A negative number under 2s complement can never be equal to its
positive as the top bit *must* be on. If two numbers are equivalent
bit-by-bit then they are equal for both signed and unsigned numbers.
|
|
This pushes a datum of the same type as the operands, which is why it
cannot use the comparator macro as that always pushes bytes.
|
|
Anything other than char (which can just use print.byte to print the
hex) and byte (which prints hexes anyway), all other types may be
forced to print a hex rather than a number if PRINT_HEX is 1.

I've made a single macro which defines a function through some common
metric, removing code duplication. Not particularly readable per se,
but using a macro expansion in your IDE allows one to inspect the code.

These new members are just signed versions of the previous members.
This makes type punning and usage for signed versions easier than
before (no need for memcpy).
|
|
|
|
So much reused code, I definitely need to find a way to make this cleaner.

As it has no dependencies on vm specifically, and it's more necessary
for any vendors who wish to target the virtual machine, it makes more
sense for inst to be a lib module rather than a vm module.
|
|
Just need to call their unsigned versions.
All comparators should push bytes as it makes return types uniform.
|
|
otherwise
Changed VERBOSE checks to ensure a degree of information.
|
|
Will cause error if used currently, which is fine.
|
|
Comparing signed and unsigned versions of numbers. Same for EQ as
well.
Notice the irregular pattern of BYTE, CHAR, INT, HWORD,LONG,WORD as
OPCODE_IS_TYPE requires the subcodes to be surrounded by BYTE and
WORD.
|
|
Prints useful and pretty messages when verbose being at least 1.
|

|
This is due to checking for equality instead of just greater than in
darr->used against darr->available.
|
|
This is an easy fix.
|
|
Doesn't make sense for them to be in the VM module when they have a
more general purpose now.
|
|
Also prints a usage for incorrect usage.
|
|
Easier to write includes now just using < with the module name, in
comparison to using relative paths.
|
|
|
|
|
|
Changed folder names for sake of clarity (will be introducing a new
build target soon), and Makefile can now easily support more targets.
