[PATCH] gas/config/tc-score7.c: Use symbol_get_frag() instead of direct reference to fix segment fault issue

[Nicholas Clifton]

Hi Chen,

> Is it patch OK? please help check when you have free time, thanks.

Approved and applied.  Note - there were similar errors in tc-score.c so 
I fixed them at the same time.

All patches should have a changelog entry, so I created this for yours:

gas/ChangeLog
2014-06-13  Chen Gang  <gang.chen.5i5j@gmail.com>

	* config/tc-score7.c: (s7_b32_relax_to_b16): Use symbol_get_frag() to 
access a symbol's
	frag.
	* config/tc-score.c (s3_relax_branch_inst16): Likewise.
	(s3_relax_cmpbranch_inst32): Likewise.



Also - this is a situation where it would have been appropriate to 
create an official bug report on the bugzilla system.

Cheers
   Nick
