            Bug ID: 27272
           Summary: Cannot build Linux kernel 5.10.11 (or 5.10.6) with
                    2.36 binutils. 2.35.1 works.
           Product: binutils
           Version: 2.36
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: binutils
          Assignee: unassigned at sourceware dot org
          Reporter: j-comm at westvi dot com
  Target Milestone: ---

Pretty much described as above. Has been verified by another user. I submitted
a bug report describing this in the Linux kernel bugzilla at
https://bugzilla.kernel.org/show_bug.cgi?id=211443

But I copy the description for that bug here.... This error is seen with 2.36
binutils *very* early in the build started with: "make mrproper; make
defconfig; make" ... it happens within a minute on my system

-------------------------

As the summary states - trying to compile kernel 5.10.11. Here is a log of what
I did. Note that I tried this both without AND with the recent patch in the git
logs to help thunk_64.S compile with LLVM. That patch, by itself, did not help.

Running GCC 10.2.0, GLIBC 2.32, binutils 2.36, kernel 5.10.11. 

When I tried kernel 5.10.6, which I had successfully compiled a short number of
days ago with binutils 2.35.1, it also did not compile. So, the upgrade from
binutils 2.35.1 to binutils 2.36 has changed something...
