For those of you working with the TiVo Linux sources, I discovered bug in
binutils-2.9.1.0.25 and binutils-2.9.5.0.14 that results in the following
sorts of error:
foobar.c: Assembler messages:
foobar.c:7868: Error: junk at end of line: `28'
It appears that the assembler has the incorrect definition for the
'dcread' instruction:
In the file binutils-2.9.5.0.14/opcodes/ppc-opc.c, the definition is as
follows:
{ "dcread", X(31,486), XRT_MASK, PPC403, { RA, RB } },
However, according to the IBM PowerPC 403GCX manual the definition is:
dcread RT,RA,RB
The patch to fix this is:
{ "dcread", X(31,486), X_MASK, PPC403, { RT, RA, RB } },
Patch the ppc-opc.c file and rebuild binutils and you're back on your way.
Otherwise, just comment out the offending line of code, such as:
asm("dcread %0,0,%1" : "=r" (tag) : "r" (p));
