>Environment:
Cross-compiling SunOS 4.1.3 to
NetBSD/mac68k, gas configured with
./configure --target=m68k-apple-netbsd
System: SunOS 4.1.3 2 sun4c
Architecture: sun4
>Description:
Here is a fragment in question from src/lib/libc/csu/m68k/crt0.c
#ifdef DYNAMIC
__asm("
.text
.align 2
___syscall:
movel a7@+,a0
movel a7@,d0
movel a0,a7@
trap #0
bcs 1f
jmp a0@
1:
moveq #-1,d0
jmp a0@
");
#endif /* DYNAMIC */
GAS 2.8.1 does not understand the statement "bcs 1f" and does not
allow numerical labels. When the label 1 is replaced with well-formed
label, the output is the same and the assembler is happy.
