This patch to libbacktrace corrects the LZMA block header parsing to
skip all the padding bytes, verifying that they are zero. This fixes
https://github.com/ianlancetaylor/libbacktrace/issues/118.

Some of the libbacktrace tests link a program and then modify the
debug info in some way. When configured with --enable-shared the
linking, using libtool, generates a shell script. That causes the
tests to fail because they can't modify the debug info of a shell
script. This patch, originally by
Reportedly when lld compresses debug sections, it fails to set the
alignment of the compressed section such that the compressed header
can be read directly. To me this seems like a bug in lld. However,
libbacktrace needs to work around it. This patch, originally by the
GitHub user ubyte, does th

Yes. I was just trying to answer your question.

This patch to the Go frontend uses the correct size and comparison
when doing an index value overflow check. This has apparently been
wrong since I introduced the code ten years ago. This fixes GCC PR
114500. Bootstrapped and ran Go testsuite on x86_64-pc-linux-gnu.
Committed to mainline.

This is OK. Thanks.

This patch to the Go frontend exports the type "any" as a builtin.
Otherwise we can't tell the difference between builtin type "any" and
a locally defined type "any".
This will require updates to the gccgo export data parsers in the main
Go repo and the x/tools repo. These updates are https://go.
This libgo patch generates better error messages then the Go GOARCH
and GOOS values can't be determined from the target. This indicates
that the target is not supported. This is for GCC PR 113530.
Bootstrapped and ran Go testsuite on x86_64-pc-linux-gnu. Committed
to mainline.
