Hi all.
Following code snippet generate these warnings:
t.c:9:9: warning: asm output is not an lvalue
t.c:10:10: warning: asm output is not an lvalue
t.c:9:9: warning: generating address of non-lvalue (11)
t.c:10:10: warning: generating address of non-lvalue (11)
The code snippet is part of the math emu in the kernel.
For sparc32 I get a lot of the "asm output is not an lvalue"
warnings.
For sparc32 I do not get the "generating address of non-lvalue".
Can you help me gettitng rid of these warnings?
Thanks in advance,
Sam
$ cat t.c
