Hi,
Wanting to look how much ram my project uses I came across the following
issue:
Using the binutils size program to have a look at the used ram gives
wrong results when you have data in the .infomem section.
The reported size of data includes the .infomem size (because .infomem
is writeable and has contents). Ok, .infomem should contain data but
this is confusing as I expect the reported data and bss sizes to
indicate how much of my valuable ram is used.
Maybe .infomem could get marked as executable so it will count to text.

example data follows:
binutils size source snippet:
---------------
if ((flags & SEC_CODE) != 0 || (flags & SEC_READONLY) != 0)
textsize += size;
else if ((flags & SEC_HAS_CONTENTS) != 0)
datasize += size;
else
bsssize += size;
---------------
$ msp430-objdump -h main.elf
