MSP430, unrecognized character `@' in symbol names.

[pftbest]

So I tried to compile core and I get this errors from assembler:

core.s: Assembler messages:
core.s:9468: Error: junk at end of line, first unrecognized character is `@'
core.s:9740: Error: junk at end of line, first unrecognized character is `@'
...

the code on line 9468 looks like this:

_ZN4core3num7dec2flt5rawfp10prev_float14_MSG_FILE_LINE17h5bcd06a3b0d78233E:
    .short  str.3@
    .short  27
    .short  str.1v

I tried both msp430-gcc (4.6.3) and msp430-elf-gcc (5.3.0) and both give the same errors. Then I've renamed symbol str.3@ to str.3_at in assembly and it compiled successfully. I think msp430 assembler just does not like @ character in symbol names. So I see 2 options:

1. Modify MSP430 target in LLVM so it will rename symbols with @
2. Modify generate_local_symbol_name to not emit @ on MSP430
