This is a JDK code review request for a pair of Full Debug Symbols
gobjcopy work arounds on Solaris. The gobjcopy utility on Solaris 10
corrupts the SUNW_* sections on objects. This has caused dtrace test
failures and Monitoring & Management test failures. The gobjcopy
utility crashes due to empty sections with the SHF_ALLOC flagset on
Solaris X64 objects. This causes build failures.
There are two new temporary work around tools:
add_gnu_debuglink - adds the ".gnu_debuglink" section to an ELF
object without corrupting the other sections in the object.
fix_empty_sec_hdr_flags - removes the SHF_ALLOC flag from empty
sections in ELF objects.
These temporary work arounds are only needed until the proper
Solaris 10 Update 6 patches are made available. The two patches
are independent of one another which is why there are two
separate temporary work arounds. However, we're putting the
temporary work arounds in place because the 7u6 project window
is closing fast.
Here is the webrev URL for the JDK8-T&L version:
This fix will also be backported to 7u6-T&L and I expect the
changes to virtually identical.
Thanks, in advance, for any reviews!
