            Bug ID: 46058
           Summary: llvm-9.01 builds llvm-tblgen but it seg faults when
                    called
           Product: libraries
           Version: 9.0
          Hardware: Sun
                OS: FreeBSD
            Status: NEW
          Severity: normal
          Priority: P
         Component: Backend: Sparc
          Assignee: unassignedbugs at nondot.org
          Reporter: nicolc at uleth.ca
                CC: llvm-bugs at lists.llvm.org

Firefox on FreeBSD 12.1, SunBlade 100 (sparc64) requires llvm-90, which starts
to get built, and completes build of llvm-tblgen but when that is called to
generate include files, llvm-tblgen seg faults and dumps core. Below is a
log...
