Does this:
/* NOTE: cagney/2003-09-05: CFI should specify the disposition
of all debug info registers. If it doesn't, complain (but
not too loudly). It turns out that GCC assumes that an
unspecified register implies "same value" when CFI (draft
7) specifies nothing at all. Such a register could equally
be interpreted as "undefined". Also note that this check
isn't sufficient; it only checks that all registers in the
range [0 .. max column] are specified, and won't detect
problems when a debug info register falls outside of the
table. We need a way of iterating through all the valid
DWARF2 register numbers. */
if (fs->regs.reg[column].how == DWARF2_FRAME_REG_UNSPECIFIED)
complaint (&symfile_complaints,
"Incomplete CFI data; unspecified registers at 0x%s",
paddr (fs->pc));
else
cache->reg[regnum] = fs->regs.reg[column];
sound like your problem? It's possible to specify initial values of
such registers with:
