* Hexadecimal number constants should be used except where decimal or binary numbers make much more sense in that constant's context.
* Hexadecimal letters should be upper-case.
* When you set two registers or two memory locations to an immediate 16-bit zero, you should use the expressions ```#<$0000``` and ```#>$0000``` (they make it obvious where you are putting the lower and upper bytes).
* If a function is declared to return a char-sized value, it actually must return an integer-sized value. (When cc65 promotes a returned value, it sometimes assumes that the value already is an integer.)
* If a function is declared to return a char-sized value, it actually must return an integer-sized value. (When cc65 promotes a returned value, it sometimes assumes that the value already is an integer.) This must be done in one of the following ways:
<pre>
lda #RETURN_VALUE
ldx #0 ; return value is char
</pre>
or, if the value is 0, you can use:
<pre>
lda #RETURN_VALUE
.assert RETURN_VALUE = 0
tax
</pre>
sometimes jumping to return0 could save a byte:
<pre>
.assert RETURN_VALUE = 0
jmp return 0
</pre>
* Functions, that are intended for a platform's system library, should be optimized as much as possible.
* Sometimes, there must be a trade-off between size and speed. If you think that a library function won't be used often, then you should make it small. Otherwise, you should make it fast.
* Comments that are put on the right side of instructions must be aligned (start in the same character columns).

<sect>Linker configuration<p>
The C libraries and code generation depend directly on a suitable linker configuration.
There are premade configuration files in the <tt/cfg&sol;/ directory, normally chosen by the
linker's selected target. These can be used as a template for customization.
The C libraries depend on several special segments to be defined in your linker configuration.
Generated code will also use some of them by default.
Some platform libraries have additional special segments.
Memory areas are free to be defined in a way that is appropriate to each platform,
and the segments they contain are used as a layer of semantics and abstraction,
to allow much of the reorganization to be done with the linker config,
rather than requiring platform-specific code source changes.
<sect1><tt/ZEROPAGE/ segment<p>
Used by the C library and generated code for efficient internal and temporary state storage,
also called "pseudo-registers".
<sect1><tt/STARTUP/ segment<p>
Used by each platform instance of the C library in <tt/crt0.s/ to contain the entry point
of the program.
The startup module will export <tt/__STARTUP__ : absolute = 1/ to force the linker to
always include <tt/crt0.s/ from the library.
<sect1><tt/CODE/ segment<p>
The default segment for generated code, and most C library code will be located here.
Use <tt/#pragma code-name/ to redirect generated code to another segment.
<sect1><tt/BSS/ segment<p>
Used for uninitialized variables.
Originally an acronym for "Block Started by Symbol", but the meaning of this is now obscure.
Use <tt/#pragma bss-name/ to redirect uninitialized variables to another segment.
<sect1><tt/DATA/ segment<p>
Used for initialized variables.
On some platforms, this may be initialized as part of the program loading process,
but on others it may have a separate <tt/LOAD/ and <tt/RUN/ address,
allowing <tt/copydata/ to copy the initialization from the loaded location
into their run destination in RAM.
Use <tt/#pragma data-name/ to redirect initialized variables to another segment.
<sect1><tt/RODATA/ segment<p>
Used for read-only (constant) data.
Use <tt/#pragma rodata-name/ to redirect constant data to another segment.
<sect1><tt/FEATURES/ table<p>
This currently defines table locations for the <tt/CONDES/
constructor, destructor, and interruptor features.
Some platform libraries use these.
The constructors will be called with <tt/initlib/ at startup,
and the destructors with <tt/donelib/ at program exit.
Interruptors are called with <tt/callirq/.
