HEAP and STACK size GCC

[Marcel Mulder]

It's not really a question but a request to Nordic. Could you change the #ifdef lines in gcc_startup_nrf51.s to .ifdef. So:

.ifdef __STACK_SIZE
.else
.endif

and

.ifdef __HEAP_SIZE
.else
.endif

With this I can use -Wa,--defsym,__HEAP_SIZE=0 when I invoke gcc to compile the assembler. #ifdef does not work and I can't find it in the documentation of GNU as.

Thanks

Is it more correct to have .ifdef instead of #ifdef?

You can use ASMFLAGS for this. ex: -D__HEAP_SIZE=1024

According to documentation (see Assembler Directives ) a dot is used.

I don't have or use ASMFLAGS because I don't use makefiles. But it's more the way how you transfer the symbols to the assembler and which syntax you use. As I mentioned I prefer the . because that the directive used in assembler.

I forgot to mention that using the # you have to use the c/c++ pre-processor. When you want to assembler the file directly with gnu-as the # will not work. You have to use the . (dot)
