URL: https://github.com/llvm/llvm-project/commit/9e956995db1fc7e792e3dfb3a465a52626195557 DIFF: https://github.com/llvm/llvm-project/commit/9e956995db1fc7e792e3dfb3a465a52626195557.diff LOG: [clang][Headers] Do not define varargs macros for __need___va_list The glibc uses the define to avoid namespace polution on headers that requires variadic argument, where the inclusion of stdarg.h is required to obtain the va_list definition. For such cases only __gnuc_va_list is required.
