Hello! Recent RA change disturbs delicate balance of register allocation, so a couple of scan tests begins to fail. Attached patch fixes these scan failures by forcing arguments of test function in registers. 2011-12-13 Uros Bizjak <ubizjak@gmail.com> PR testsuite/51524 * gcc.target/i386/bmi2-mulx32-1.c (gen_mulx): Add attribute regparm(2). * gcc.target/i386/bmi2-mulx32-2.c (calc_mulx_u32): Ditto. Tested on x86_64-pc-linux-gnu {,-m32}, committed to mainline SVN. Uros.
