Assembling with GNU and ADS

For our kernel I use a combination of C-Preprocessor and perl. I.e. I have one source that I pre-process to get ADS,IAR and GNU assembly.

This works fine (I do this for various CPUs).

Any chance of an example of what you mean ?

TIA, HG

This is a total hack and probably most offensive to perl experts, but worked for me where I had to take a GAS file and assemble it using ADS:

while () { s/@/ ;@/; s/^(\w+):/$1/; s/\.section.*/ AREA |x|,code,readonly/; s/\.equ ([^\s]+),\s+([^\s]+)/$1 equ $2/; s/\.global\s+([^\s]+)/ EXPORT $1/; print ; } print "\n END\n";

Obviously you'll have to extend it to cover GAS keywords that weren't in the code I was assembling. Just pipe the GAS file through the perl to get ADS compatible code...

Peter.

In my source I have: #define ARM 1 #define GNU 2

#if COMPILER == ARM

MACRO SC_FUNC32 $name CODE32 EXPORT $name $name MEND

#define LONG DCD #endif #if COMPILER == GNU .macro SC_FUNC32 name .code 32 .type \name,function \name: .endm

#define LONG .long #endif

Inside the source I only use macros for things that are specific to an assembler.

Two produce the actual files I'll pre-process the original source gcc -E -DCOMPILER=1 source.S >source_ads.s or gcc -E -DCOMPILER=2 source.S >source_gnu.S

Net effect: Comments are stripped if written as C comments.

After the above state you might use a simple C program or perl script to remove empty lines.
