2024-05-06riscv mcontext_t/sigcontext: use __aligned__ instead of alignedMichael Forney-1/+1
aligned may be defined by the application for its own use before bits/signal.h is included.
2024-02-29riscv: define REG_S1 and REG_S2Khem Raj-0/+2
These are used by applications to access members of mcontext, and are also defined by other libcs on linux.
2024-02-29riscv32: add arch headersStefan O'Rear-0/+118
These are mostly copied from riscv64. _Addr and _Reg had to become int to match compiler-controlled parts of the ABI (result type of sizeof, etc.). There is no kernel stat struct; the userspace stat matches glibc in the sizes and offsets of all fields (including glibc's __dev_t __pad1). The jump buffer is 12 words larger to account for 12 saved double-precision floats; additionally it should be 64-bit aligned to save doubles. The syscall list was significantly revised by deleting all time32 and pre-statx syscalls, and renaming several syscalls that have different names depending on __BITS_PER_LONG, notably mmap2 and _llseek. futex was added as an alias to futex_time64 since it is widely used by software which does not pass time arguments.
