[PATCH] Allow MIPS call-saved-{4-6}.c tests to correctly run for micromips

[Andrew Bennett]

Hi,

The call-saved-{4-6}.c tests in the mips testsuite fail for micromips.  The 
reason is 
that micromips uses the swm and lwm instructions to save/restore the call-saved 
registers 
rather than using the sw and lw instructions.  The swm and lwm instructions 
only list 
the range of registers to use ie. $16-$25 and hence some of the scan-assembler 
patterns fail.  This fix adds the NO_COMPRESSION attribute to the foo function 
to 
force the tests to always compile as mips.
 
I have tested this for both mips and micromips, and the tests now pass 
successfully.  
The ChangeLog and patch are below.

Ok to commit?


Many thanks,


Andrew

        * gcc.target/mips/call-saved-4.c: Add NO_COMPRESSION attribute.
        * gcc.target/mips/call-saved-5.c: Likewise.
        * gcc.target/mips/call-saved-6.c: Likewise.
