[PATCH] MIPS: Do not force the n32.S file to be assembled as MIPS4

[Andrew Bennett]

Hi,

The n32.S file in the MIPS backend currently is forced to be compiled as MIPS4.
This could lead to the wrong instruction encodings being used when assembling
for newer MIPS architectures.  This patch only forces the .set mips4 constraint
if the MIPS architecture provided by the compiler is older than MIPS4.

The patch and ChangeLog are below.

Regards,



Andrew

	* src/mips/n32.S: Only force the file to be assembled as MIPS4 if
	the architecture provided by the compiler is older than MIPS4.
