--- Comment #3 from suzuki toshiya <[email protected]> --- Considering that "%M" does not set arg_going (and would be concatenated to the following token), the designed usage of "%R" is "-isysroot %R/", not "-isysroot %R"? If so, I hope the default SYSROOT_SPEC in gcc.cc is updated to "-sysroot %R/" to indicate its designed usage. #ifndef SYSROOT_SPEC # define SYSROOT_SPEC "--sysroot=%R" #endif
