From 01d9fe4d9f7cce7a6dbaece0e2e405a2e3279244 Mon Sep 17 00:00:00 2001 From: Stefan O'Rear Date: Thu, 3 Sep 2020 05:40:29 -0400 Subject: riscv32: add arch headers 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. --- arch/riscv32/bits/stdint.h | 20 ++++++++++++++++++++ 1 file changed, 20 insertions(+) create mode 100644 arch/riscv32/bits/stdint.h (limited to 'arch/riscv32/bits/stdint.h') diff --git a/arch/riscv32/bits/stdint.h b/arch/riscv32/bits/stdint.h new file mode 100644 index 00000000..d1b27121 --- /dev/null +++ b/arch/riscv32/bits/stdint.h @@ -0,0 +1,20 @@ +typedef int32_t int_fast16_t; +typedef int32_t int_fast32_t; +typedef uint32_t uint_fast16_t; +typedef uint32_t uint_fast32_t; + +#define INT_FAST16_MIN INT32_MIN +#define INT_FAST32_MIN INT32_MIN + +#define INT_FAST16_MAX INT32_MAX +#define INT_FAST32_MAX INT32_MAX + +#define UINT_FAST16_MAX UINT32_MAX +#define UINT_FAST32_MAX UINT32_MAX + +#define INTPTR_MIN INT32_MIN +#define INTPTR_MAX INT32_MAX +#define UINTPTR_MAX UINT32_MAX +#define PTRDIFF_MIN INT32_MIN +#define PTRDIFF_MAX INT32_MAX +#define SIZE_MAX UINT32_MAX -- cgit v1.2.1
