New Revision: 263320
URL: http://svnweb.freebsd.org/changeset/base/263320
Log:
Add separate patch files for all the customizations we have currently
applied to our copy of llvm/clang. These can be applied in alphabetical
order to a pristine llvm/clang 3.4 release source tree, to result in the
same version used in FreeBSD.
This is intended to clearly document all the changes until now, which
mostly consist of cherry pickings from the respective upstream trunks,
plus a number of hand-written FreeBSD-specific ones. Hopefully those
can eventually be cleaned up and sent upstream too.

+This is a set of individual patches, which contain all the customizations to
+llvm/clang currently in the FreeBSD base system. These can be applied in
+alphabetical order to a pristine llvm/clang 3.4 release source tree, for example
+by doing:
+
+svn co https://llvm.org/svn/llvm-project/llvm/tags/RELEASE_34/final llvm-3.4-final
+svn co https://llvm.org/svn/llvm-project/cfe/tags/RELEASE_34/final llvm-3.4-final/tools/clang
+cd llvm-3.4-final
+for p in /usr/src/contrib/llvm/patches/patch-*.diff; do
+ patch -p0 -f -F0 -E -i $p -s || break
+done
+
+A number of these consist of hand-written modifications, specifically for
+FreeBSD, while most others are cherry pickings off the llvm and clang trunks.
+When a new version of llvm/clang is eventually imported, those latter ones will
+largely disappear.

+Pull in r195391 from upstream llvm trunk (by Eric Christopher):
+
+ In Dwarf 3 (and Dwarf 2) attributes whose value are offsets into a
+ section use the form DW_FORM_data4 whilst in Dwarf 4 and later they
+ use the form DW_FORM_sec_offset.
+
+ This patch updates the places where such attributes are generated to
+ use the appropriate form depending on the Dwarf version. The DIE entries
+ affected have the following tags:
+ DW_AT_stmt_list, DW_AT_ranges, DW_AT_location, DW_AT_GNU_pubnames,
+ DW_AT_GNU_pubtypes, DW_AT_GNU_addr_base, DW_AT_GNU_ranges_base
+
+ It also adds a hidden command line option "--dwarf-version=<uint>"
+ to llc which allows the version of Dwarf to be generated to override
+ what is specified in the metadata; this makes it possible to update
+ existing tests to check the debugging information generated for both
+ Dwarf 4 (the default) and Dwarf 3 using the same metadata.
