------- Additional Comments From fruffell at cs dot uwaterloo dot ca 2007-03-20 14:51 ------- Created an attachment (id=1633) --> (http://sourceware.org/bugzilla/attachment.cgi?id=1633&action=view) A test case illustrated the a rexB prefixed 0x90 instruction is not a nop.
gcc -c xchg-eax-stub.c as xchg-eax.asm -o xchg-eax.o gcc -o xchg-eax xchg-eax.o xchg-eax-stub.o If you change 0x41 in the asm file to 0x90 the output will show that 0x90 is a true nop. With the 0x41 in the asm file, the output will show that 0x41 0x90 is not a nop. -- http://sourceware.org/bugzilla/show_bug.cgi?id=4218 ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is. _______________________________________________ bug-binutils mailing list bug-binutils@gnu.org http://lists.gnu.org/mailman/listinfo/bug-binutils
