            Bug ID: 33021
           Summary: [AArch64] GlobalISel emits calls to fabs
           Product: libraries
           Version: trunk
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: GlobalISel
          Assignee: unassignedbugs at nondot.org
          Reporter: diana.picus at linaro.org
                CC: llvm-bugs at lists.llvm.org

When running the test-suite on an APM, we get linker errors on
MultiSource/Benchmarks/Prolangs-C/plot2fig due to undefined references to fabs.

The calls are generated from space.c.

For the same file, FastISel does not generate calls, but FABSDr. I'll attach a
reproducer.
