Add missing tab to output of "ldmfd". (output_return_instruction): Output LDMFD with SP update rather than POP when returning from interrupt handler. * gcc.target/arm/interrupt-1.c: Change dg-compile to dg-assemble. Add -save-temps to dg-options. Scan for ldmfd rather than pop instruction. * gcc.target/arm/interrupt-2.c: Likewise. * gcc.target/arm/pr70830.c: New test. Added: trunk/gcc/testsuite/gcc.target/arm/pr70830.c Modified: trunk/gcc/ChangeLog trunk/gcc/config/arm/arm.c trunk/gcc/testsuite/ChangeLog trunk/gcc/testsuite/gcc.target/arm/interrupt-1.c trunk/gcc/testsuite/gcc.target/arm/interrupt-2.c
