Subject: The ARM assembler is not assembling the following instruction
X-Git-Tag: binutils-2_10~5
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=9fa3abac636abada18d487527408bfe341f8f84a;p=thirdparty%2Fbinutils-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.

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