2026-03-12loongarch64: add lsx and lasx regset definitionXing Li-0/+14
2026-03-12loongarch64: add fpu and simd context to signal.hJianTao Shan-0/+43
The signal stack extension field of loongarch64 is mutable, and the types are distinguished according to some magic.

2025-02-21loongarch64: add bits/hwcap.h for cpu feature bits in AT_HWCAP auxv entryXing Li-0/+14
2024-05-07stdint.h: derive limits from __LONG_MAX, use common fast16 typesRich Felker-20/+0
the bits file is retained, but as a single generic version, to allow for the unlikely future possibility of letting a new arch define something differently.
2024-05-07sys/reg.h: derive __WORDSIZE from __LONG_MAXRich Felker-2/+0
this removes an otherwise-unnecessary bits header from most archs, replacing it with an empty generic version.
2024-05-07unistd.h: derive ILP32/LP64 macros from __LONG_MAX instead of arch bitsRich Felker-2/+0
2024-05-07unify bits/stat.h for all archs sharing a common definitionRich Felker-18/+0
future archs should not define their own bits/stat.h but use this generic one.
2024-05-07align aarch64, riscv64, loongarch64 stat structure padding typeRich Felker-1/+1
this change is purely to document that they are the same in preparation to remove the arch-specific headers for these archs and replace them with a generic version that matches riscv32 and can be shared by these and all future archs.
2024-02-29loongarch64: add new syscall numberswanghongliang-0/+15
2024-02-29loongarch64: remove getrlimit/setrlimit syscall numbersRich Felker-2/+0
these are not supported by the kernel for new archs; prlimit64 replaces them.
2024-02-29loongarch64: remove ptrace.h macroswanghongliang-4/+0
2024-02-26add loongarch64 user.h structs; adjust elf_fpreg_t and ELF_NFPREGHongliang Wang-2/+21
user_regs_struct and user_fp_struct were missing from the initial commit of the port. the union type for elf_fpreg_t and the new value of ELF_NFPREG are made consistent with glibc.
2024-02-26add loongarch64 signal.h register index macroswanghongliang-0/+11
