- Reply-to: gcc-bugzilla at gcc dot gnu dot org
GCC uses local label names .L1, .L2, etc. on this platform.
However these same assembly labels are used for functions named "L1" or "L2".
wolfgang@gorecki wolfgang $ cat L.c
int L2(int x)
{
if(x > 5)
return -42;
else
return 42;
}
wolfgang@gorecki wolfgang $ gcc -c L.c
/tmp/ccL2lhwX.s: Assembler messages:
/tmp/ccL2lhwX.s:26: Error: symbol `.L2' is already defined
Observed on gentoo powerpc64; also observed on a gcc-3.4.2 cross-compiling from powerpc-apple-
darwin to powerpc64-unknown-linux.
