2023-06-22asm-generic: Unify uapi bitsperlong.h for arm64, riscv and loongarchTiezhu Yang1-9/+0
Now we specify the minimal version of GCC as 5.1 and Clang/LLVM as 11.0.0 in Documentation/process/changes.rst, __CHAR_BIT__ and __SIZEOF_LONG__ are usable, it is probably fine to unify the definition of __BITS_PER_LONG as (__CHAR_BIT__ * __SIZEOF_LONG__) in asm-generic uapi bitsperlong.h. In order to keep safe and avoid regression, only unify uapi bitsperlong.h for some archs such as arm64, riscv and loongarch which are using newer toolchains that have the definitions of __CHAR_BIT__ and __SIZEOF_LONG__.

2023-05-01tools/perf: Add basic support for LoongArchHuacai Chen2-0/+49
Add basic support for LoongArch, which is very similar to the MIPS version. Signed-off-by: Ming Wang <wangming01@loongson.cn> Signed-off-by: Huacai Chen <chenhuacai@loongson.cn>
2023-04-19tools/loongarch: Use __SIZEOF_LONG__ to define __BITS_PER_LONGTiezhu Yang1-1/+1
Although __SIZEOF_POINTER__ is equal to _SIZEOF_LONG__ on LoongArch, it is better to use __SIZEOF_LONG__ to define __BITS_PER_LONG to keep consistent between arch/loongarch/include/uapi/asm/bitsperlong.h and tools/arch/loongarch/include/uapi/asm/bitsperlong.h.

2023-02-25tools: Add LoongArch build infrastructureHuacai Chen1-0/+9
We will add tools support for LoongArch (bpf, perf, objtool, etc.), add build infrastructure and common headers for preparation. Signed-off-by: Huacai Chen <chenhuacai@loongson.cn>
