            Bug ID: 44244
           Summary: logb and logbl tests fail for riscv target
           Product: compiler-rt
           Version: unspecified
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: builtins
          Assignee: unassignedbugs at nondot.org
          Reporter: pzheng at codeaurora.org
                CC: llvm-bugs at lists.llvm.org

Two tests are failing for riscv target.

Failing Tests (2):
    Builtins-riscv32-linux :: compiler_rt_logb_test.c
    Builtins-riscv32-linux :: compiler_rt_logbl_test.c

In order to run the builtin tests, I had to apply the following patch for the
COMPILER_RT_TEST_COMPILER_CFLAGS to take effect. Not sure if this is needed for
other people.
