    Tested on Loongson-3C5000L-LL machine, using CLFS7.3 system.

    $ gcc -v
    gcc version 13.0.0 20221018 (experimental) (GCC)

    # make check -j32
    /home/loongson/build_glibc/math/test-tgmath3-atan2.c:
    在函数‘test_atan2_84’中:
    /home/loongson/build_glibc/math/test-tgmath3-atan2.c:903:59:
    错误:conflicting types for ‘var__Float32x’; have ‘double’
    903 | extern typeof (atan2 (vol_var__Float32x, vol_var_char))
    var__Float32x __attribute__ ((unused));
    |
    ^~~~~~~~~~~~~

    There was a build error in make check, so only tst-mallocfork3-
    malloc-check was tested separately.

    # make test t=malloc/tst-mallocfork3-malloc-check
    make[2]: 离开目录“/home/loongson/glibc/malloc”
    PASS: malloc/tst-mallocfork3-malloc-check
    original exit status 0
    info: signals received during fork: 301
    info: signals received during free: 1693
    info: signals received during malloc: 119
    make[1]: 离开目录“/home/loongson/glibc”

    A total of five tests are PASS, and the serial port does not display
    CallTrace.

    Youling.
