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.
