CCSTUDIO: CCS10.1.1 - ARM - TI v20.2.4 LTS

Here is a contrived example which demonstrates the problem.

These two commands show a stub main program, and a linker command file that uses an unusual method for creating the stack.

C:\workdir>type stub_main.c
int main()
{
   return 0;
}

C:\workdir>type stub_link.cmd
SECTIONS
{
    .stack:
    {
        . += 0x1000;
    } > RAM
}

This command builds the program ...

C:\workdir>armcl -mv7m3 -mt -me stub_main.c -z -o stub_main.out -w stub_link.cmd
<Linking>
warning: creating output section ".text" without a SECTIONS specification
warning: creating ".stack" section with default size of 0x800; use the -stack
   option to change the default size

The warnings are issued because the -w linker option is used.  The first warning is correct.  The second warning is not, and this is the bug.  Even though the method used to create it is unusual, a stack is created and it is larger then 0x800 bytes.  Therefore the warning should not be issued.

Thanks and regards,
