Fix the return value when we found a symbol in .dynstr. This nasty bug was

preventing a lot of symbol lookups in dtruss -s, for example.

- Compute the correct size to reallocate when doubling the size of the

  array of loaded objects to avoid a buffer overrun.
- Use reallocf() to avoid leaking memory if the realloc() fails.

Fix libproc test case to work with clang premature optimization

observed with -O2 (used by default).
Avoid function inlining for t1_bkpt_t on which we set a breakpoint.
Otherwise the address of the function is never called thus the
breakpoint never triggers.

Implement DTrace for PowerPC. This includes both 32-bit and 64-bit.

There is one known issue:  Some probes will display an error message along the
lines of:  "Invalid address (0)"

I tested this with both a simple dtrace probe and dtruss on a few different
binaries on 32-bit.  I only compiled 64-bit, did not run it, but I don't expect
problems without the modules loaded.  Volunteers are welcome.

fix a serious bug in libproc's proc_attach

2011-08-03T09:55:59+00:00

proc_attach always frees any struct proc_handle data
that it allocates, but that is supposed to be done
only in error conditions.
