[avr-gcc-list] Assembler error message

I'm trying to define assembler macro for clearing bits in register:

#define CLEARBIT_CONST(var,const_mask) \
 asm volatile (\
  "cbr %0, %1 "\
  : /* no outputs */\
  : "r" ((uint8_t) (var)), \
    "i" ((uint8_t) (mask)) \

When I compile my program I get error:
c:\windows\temp\ccFvZigb.s: Assembler messages:
c:\windows\temp\ccFvZigb.s:3523 Error: number must be less than 256

I think it comes form inproper use of this macro - but how can I find error
in temp file ccFvZigb.s ? Why error is not shown on one of end files like
.s, .lst or similar ?

Thanks in advance,

Robert Rozman

Zadeva: [avr-gcc-list] strlen bug...


I recently discovered that there was no way to compile any source
code which uses strlen() (the problem is at compile-time, not at
link-time). Maybe some of you already knew about it as it looks
like it is not specific to my program ('internal error').

Here is what i got :

avr-gcc -Wall -I../include/ -O9 -mmcu=atmega103   -c main.c -o main.o
main.c: In function `lcd_manager':
main.c:206: Unrecognizable insn:
(insn 112 108 113
            (set (reg:HI 56)
                        (mem:BLK (reg/f:HI 57) 0)
                        (const_int 0 [0x0])
                        (const_int 1 [0x1])
                    ]  0))
        ] ) -1 (nil)
main.c:206: Internal compiler error in extract_insn, at recog.c:2254
Please submit a full bug report, with preprocessed source if appropriate.
See <URL:http://www.gnu.org/software/gcc/bugs.html> for instructions.
make: *** [main.o] Error 1

Anyway, if someone wants the whole source code, i can send it.
