msp430fr2355-quickstart's Issues

Timer examples fails build with linker error when LTO is enabled

When building the timer example on release mode with LTO, the build fails at link time with the following error:
note: "msp430-elf-gcc" "-mcpu=msp430" "-c" "-o" "/home/yuhan/projects/rust/embedded/msp430-quickstart/target/msp430-none-elf/release/examples/timer-4c17cb377a7ad494.timer.6hi1yd99-cgu.0.rcgu.o" "/home/yuhan/projects/rust/embedded/msp430-quickstart/target/msp430-none-elf/release/examples/timer-4c17cb377a7ad494.timer.6hi1yd99-cgu.0.rcgu.s"

note: /home/yuhan/projects/rust/embedded/msp430-quickstart/target/msp430-none-elf/release/examples/timer-4c17cb377a7ad494.timer.6hi1yd99-cgu.0.rcgu.s: Assembler messages:
/home/yuhan/projects/rust/embedded/msp430-quickstart/target/msp430-none-elf/release/examples/timer-4c17cb377a7ad494.timer.6hi1yd99-cgu.0.rcgu.s:60: Error: redefined symbol cannot be used on reloc.

The error is due to the following LLVM code (https://github.com/access-softek/msp430-clang/blob/672cd1feb4044a11ed4974f848af3cb676aafde4/src/llvm/lib/Target/MSP430/MSP430AsmPrinter.cpp#L169) generating output incompatible with our current linker scripts.

Potential update to `v0.2.0`

I have made a PR for a breaking change in svd2rust. You may wish to regenerated your device crate using this change, as well as test the upcoming v0.2.0 of msp430-rt: https://github.com/cr1901/msp430-quickstart/tree/rt-up

All crates can be downloaded as git dependencies for the time being, I would like someone besides me to test that things don't break.
