syntax for asm in sdcc - john111w - 2012-06-08 11:50:00
I need to use the sdcc compiler in an IDE. I have about 16K of ASM51 code that I need to compile with sdcc so that I can use the source in the debug pane. The IDE only shows dissambly (with label numbers) unless you use C. So I fugured I'd create a C "shell" and import my asm51 file Where can I go to learn how to embed the asm? The IDE has a C example which compiles with sdcc. I tried 2 hours of web searches last night to find the syntax to add 2 trial lines. __asm mov a,b mov b,a __ endasm I tried single underscore, double underscore, quotes, slashes, parens, as shown in many web search examples I even tried without the mov's just __asm/ __endasm as shown in an SDCC forum example. I can't see how to create a thread in the SourceForge.net to ask this question Help is greatly appreciated. --------------------------------------- Posted through http://www.EmbeddedRelated.com

You shouldn't -- but the compiler is obviously being picky on you. (I really like the Gnu "asm" syntax by the way -- in my opinion it's the best thought-out, and complete, way to implement assembly that I've seen). As a work-around, can you implement those critical functions entirely in assembly? You'll have call overhead, but you'll have less totally non- portable structures scattered around your code. -- My liberal friends think I'm a conservative kook.

Some time ago this was changed to also allow __asm and __endasm. Recently the old _asm and _endasm has been removed, and sdcc now only supports the standard-compliant __asm and __endasm. So depending on how old the sdcc version used is, it will support _asm, __asm or both. Philipp
