ImageCraft V7 Symbol Importing for MSP430static

I just committed r38 of msp430static which adds support for importing symbols from ImageCraft V7 for MSP430. A short example follows.

I'll use the following C code, but any will suffice.

void main(){
         int x=0xFFFF;
         x+=1;
         x+=0xFFFF;
         x+=abs(5);
}

Compiling it yields many files. The two of interest are FOO.hex and FOO.mp. The former is imported by converting it to msp430-elf and dumping the resulting ELF file.

karen% msp430-objcopy -I ihex -O elf32-msp430  FOO.hex foo.exe
karen% msp430-objdump -D foo.exe | m4s init
karen%

Symbols are then imported with the .symbols.import.ic7 macro.

karen% m4s .symbols.import.ic7 <FOO.mp
karen%

At this point, msp430static knows the name of every function in my image. Here is the callgraph of my program above.


Note that my examples are in Linux. ICC 7 works perfectly as both an IDE and compiler under Wine.
