Subject: The ARM assembler is not assembling the following instruction
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=a6836251f636c0cb1078966331647d70376208ed;p=binutils-gdb.git

The ARM assembler is not assembling the following instruction
correctly.

	mrs	lr, spsr

The string pointer is advanced to far before the check to set
the SPSR bit.

Thu Jun 01 2000  Scott Bambrough <scottb@netwinder.org>

	* config/tc-arm.c (do_mrs): Allow SPSR_BIT to be set correctly.
