-Subject: [PATCH] symbol: Account for prelinked shared objects
-
-Some projects, such as those derived from Yocto, tend to prelink their
-binaries and libraries to reduce runtime overhead. Currently this trips
-up pyflame in its symbol address calculations, and leads to ptrace
-failures due to spurious addresses:
-
-   $ pyflame -t python -c "print 'foo'"
-   Unexpected ptrace(2) exception: Failed to PTRACE_PEEKDATA (pid 1482, addr 0x9f9b1d70): Input/output error
-   Unexpected ptrace(2) exception: Failed to PTRACE_PEEKDATA (pid 1482, addr 0x9f9b1d70): Input/output error
-   Unexpected ptrace(2) exception: Failed to PTRACE_PEEKDATA (pid 1482, addr 0x9f9b1d70): Input/output error
-   Unexpected ptrace(2) exception: Failed to PTRACE_PEEKDATA (pid 1482, addr 0x9f9b1d70): Input/output error
-   Unexpected ptrace(2) exception: Failed to PTRACE_PEEKDATA (pid 1482, addr 0x9f9b1d70): Input/output error
-   ...
-
-Add support for reading a prelinked base p_vaddr out of the ELF and
-adjust the PyAddresses values accordingly.
