URL: https://github.com/llvm/llvm-project/commit/1bc85cbbb80397cbc165500cc336fe8325bed07d DIFF: https://github.com/llvm/llvm-project/commit/1bc85cbbb80397cbc165500cc336fe8325bed07d.diff LOG: [Sanitizer][RISCV] Fix redefinition of REG_SP The include header sys/ucontext.h already defines REG_SP as 2, causing redefinition warnings during compilation. This patch fixes that issue. (We also can't just use the numerical definition provided by the header, as REG_SP is used in this file this refers to a struct field.)
