[xiangzhai]

Hi,

Testcase testadc Passed on la64_lbt supported platform:

Dynarec for LoongArch with extension LSX LASX LBT_X86 PageSize:16384 Running on Loongson-3A5000-HV with 4 Cores
Will use time-based emulation for rdtsc, even if hardware counter are available
Will use Software counter measured at 1.0 GHz emulating 2.0 GHz
Params database has 14 entries

Thanks for the contribution, please format your code using clang-format with the .clang-format file we have in the repo. I would like all the LA64 DynaRec code to be formatted.

This is wrong too.
