I have backported the issue upstream in version 2.31. Backporting it into 2.30 requires a tiny bit more of work and testing, I'll do that in the next days. Note that we are waiting for the green light from the release team to upload 2.30 to unstable, so there is no need to fix version 2.29.

Package: src:glibc Version: 2.29 Severity: serious https://sourceware.org/bugzilla/show_bug.cgi?id=25523 https://sourceware.org/git/?p=glibc.git;a=commit;h=4fbba6fe904d0094ddc4284066b3860d119cbd4a mips: Fix argument passing for inlined syscalls on Linux [BZ #25523] According to [gcc documentation][1], temporary variables must be used for the desired content to not be call-clobbered. Fix the Linux inline syscall templates by adding temporary variables, much like what x86 did before (commit 381a0c26d73e0f074c962e0ab53b99a6c327066d). Tested with gcc 9.2.0, both cross-compiled and natively on Loongson 3A4000. [1]: https://gcc.gnu.org/onlinedocs/gcc/Local-Register-Variables.html
