Hi Martin (and everyone else on the gcc list).
I appreciate your input and kind reply to my proposal. :)

Hi all.
I know it's possible to declare a variable 'read-only' by using 'const'.
When working with microcontrollers (small ICs, which often requires you to
write your code at driver-level), you need to be able to declare a structure
member 'read-only', 'write-only' or 'read+write'.
In addition
Hi all.
I'm trying to build GCC 4.8.3 with ObjC support for ARM Cortex-M4.
I had this working with an earlier version of GCC (I think it was GCC 4.5).
-But now I get build errors.
It seems to me that it's required to add the --enable-libobjc switch (otherwise
I the build stops when it can't find
Hi list.
I think I've found a bug in where gcc checks if array indices are in range.
Here's my test-code:
---8-8-8-

* command-line:
* arm-none-eabi-gcc -O2 elementTest.c -o elementTest
*/
#include stdint.h

int main(int argc,

In both cases you cannot actually use the memory at *p. I think gcc is
detecting the indexing but not the access.
That makes sense!

I'm using a GCC toolchain similar to Yagarto for making code for the LPC1768
microcontroller.
My gcc is version 4.7.2, my binutils is version 2.23.1
To make parts of my code run faster (a timer interrupt to be exact), I've used
a modified linker script, so that I get a '.fastcode' section.

Hi Andrew.
Thank you, I will. Of course; I'm just a bit absent at the moment. ;)
In fact, I'm sure this must be a linker problem.
Love
Jens
