Hello, Given the PowerPC assembler: cagney@puddin$ cat bug.s srwi 11,10,0 rlwinm 11, 10, 32, 0, 31 where the second instruction is what `srwi' is expanded into, gas-950726 gives the warning: cagney@puddin$ powerpc-unknown-eabi-as -v bug.s -o bug.o GNU assembler version 950726 (powerpc-unknown-eabi), using BFD version cygnus-2.5 bug.s: Assembler messages: bug.s:1: Warning: operand out of range (32 not between 0 and 31) bug.s:2: Warning: operand out of range (32 not between 0 and 31) While the warning is valid (32 is indeed > 31) and gas is still generating correct code (mapping it to zero), I think that for this case the warning may possibly need to be suppressed. The assembler was output by ss-950805 from the C file c-torture/execute/930921-1.c: bash$ powerpcle-unknown-eabi-gcc 930921-1.c -msoft-float /applications/clayton/root/usr/lib/crt0.o -L/applications/clayton/root/usr/lib -lc -mstrict-align /var/tmp/cc026999.s: Assembler messages: /var/tmp/cc026999.s:34: Warning: operand out of range (32 not between 0 and 31) Any thoughts? Andrew.
