Summary: Simple HC08 program cannot be output to ELF 

Initial Comment:
I really wanted to use the ELF format in my project, but I could not get a simple test working.

int main()
{
	return 0;
}

sdcc test.c -mhc08 --out-fmt-elf
test.asm:99: Error: <o> .org in REL area or directive / mnemonic error
test.asm:105: Error: <o> .org in REL area or directive / mnemonic error
removing test.rel

Blake,

Can you elaborate on that?
What do you consider code bloat?
And why do you prefer the ELF format if it is not for debugging info?

Message:
--debug does work. However the code bloat is a serious complication.

Message:
A bit of experimenting reveals that the sdas08 assembler does not like
statement like:

S(null)$main$4 ==.

which only show up when the -out-fmt-elf option is present.
You may try to add the "--debug" option before the -out-fmt-elf as a
work-around.

The above assembly lines are generated by  hc08_emitDebuggerSymbol .
Turning on --debug removes the "(null)" from the assembly code generated.

Aside from that, both the assembly code and 
the assembler options (-plosgffw) match.
