Just because the compiler produces bad code doesn't mean gas needs to correct it. Identical hand-written code like this absolutely needs to be diagnosed. As since there's no way to tell hand written code from compiler generated one, the fix will need to be in the compiler (otherwise I might accept us adjusting things for the compiler's sake). > The fix is also incomplete: > > [hjl@gnu-cfl-2 pr26685]$ cat foo.s > movdir64b foo, %eax > movdir64b 0x12345678, %eax > [hjl@gnu-cfl-2 pr26685]$ make foo.o > ./as -o foo.o foo.s > foo.s: Assembler messages: > foo.s:1: Error: invalid register operand size for `movdir64b' > foo.s:2: Error: invalid register operand size for `movdir64b' > make: *** [<builtin>: foo.o] Error 1 > [hjl@gnu-cfl-2 pr26685]$ This is a different problem, and indeed wants fixing. -- You are receiving this mail because: You are on the CC list for the bug.
