%description
TI has partnered with Red Hat to bring you a new and fully supported open
source compiler. This free GCC compiler has no code size limit. In addition,
this compiler can be used standalone or selected within Code Composer 6.0
(beta).

%package -n msp430-elf-gcc
Summary: GCC for the MSP430
Group: Development/Debuggers
%description -n msp430-elf-gcc
This is a cross compiling version of GNU GCC, which can be used to
compile for the %{target} platform, instead of for the native %{_arch}
platform.

%package -n msp430-elf-gdb
Summary: GDB for the MSP430
Group: Development/Debuggers
%description -n msp430-elf-gdb
This is a version of GDB, the GNU Project debugger, for (remote)
debugging %{target} binaries. GDB allows you to see and modify what is
going on inside another program while it is executing.

%package -n msp430-elf-binutils
Summary: GCC for the MSP430
Group: Development/Debuggers
%description -n msp430-elf-binutils
This is a Cross Compiling version of GNU binutils, which can be used to
assemble and link binaries for the %{target} platform, instead of for the
native %{_arch} platform.
