Re: [PATCH] Add support for TIRTOS


Hi Ashish,

The top-level files in src need to be submitted to a different mailing list.
Check out the top-level src/MAINTAINERS file for details.  

I have a few comments about the newlib/libgloss bits.

You're logic in checking the may_supply_syscalls flag is incorrect.  The may_supply_sycalls option
is designed to allow older sys dirs to supply the low-level syscalls that libgloss is meant
to supply.  The libc/sys/arm directory is one of those.  The problem with the sys dir supplying syscalls is it builds
these into newlib itself and thus changing board models or using a simulator can't be done by simple linker usage.
In your case, you are overriding the sys_dir directory so libc/sys/arm won't even be used and thus there is no reason to set
the ARM_RDI_MONITOR flag.  You do, however, need to set the have_crt0 flag to "no".  This is because your sys directory
does not create a crt0.o file which the build will expect to copy up the chain.  I would have expected your build to fail
without you specifying --disable-newlib-may-supply-syscalls.

Can you also please note whether you have written
100% of the code and whether you have permission from your employer to 
donate this code to newlib?

Thanks,

-- Jeff J.
