Hello ports --
It was hinted at recently that a port of dwz might be desirable. Here is
one.
---
pkg/DESCR:
dwz is a program that attempts to optimize DWARF debugging information
contained in ELF shared libraries and ELF executables for size, by
replacing DWARF information representation with equivalent smaller
representation where possible and by reducing the amount of duplication
using techniques from DWARF standard appendix E - creating
DW_TAG_partial_unit compilation units (CUs) for duplicated information
and using DW_TAG_imported_unit to import it into each CU that needs it.
---
Can verify that it does in fact do something with some test binaries on
amd64 (diffing the output of `objdump -g' from a newer binutils does show
substantial differences), but I don't know enough about DWARF symbols to
authoritatively say anything more than that. Testing on other archs would be
greatly appreciated.
OK?
Thanks for the initial work, but you're not thinking straight.
Here's an updated port.
You'll notice the dependencies on gmake and xz are gone, which is
required if we want to use this for DEBUG_PACKAGES eventually ;)
Unless I'm missing something, you sent me back my own port without changes.
I'm fine with switching to the gz tarball and removing the dependency on
gmake. I get why.
Oops, bad tarball
Like I said before, this is all fine.
At some point, perhaps someone should look into making the tests work.
I have never been able to figure out how to get dejagnu to work so
I disabled them but that might not be ideal.
I tried to enable the tests but didn't get anywhere.
Here's an unrelated diff: fix endianness checks. ok?
I don't have any reliable BE machines at the moment but hoping to remedy
that soon. But yes ok for this as I'm guessing it improves things there.
