Bootstrap comparison failure! gcc/function-tests.o differs And the same reason: unique, static symbol that includes a random timestamp. 1949c1949 < [1936] m 0x00000060 1 1 0x02 0x0000 _GLOBAL__F__nasfarm_edelsohn_src_gcc_8.0.1_RC_20180425_gcc_function_tests.c_DFF67DD7_0x4eda2a0ca57bf446 --- > [1936] m 0x00000060 1 1 0x02 0x0000 _GLOBAL__F__nasfarm_edelsohn_src_gcc_8.0.1_RC_20180425_gcc_function_tests.c_DFF67DD7_0xbe25963bf76153c The entire file is protected by CHECKING_P. As DEBUG_FUNCTION propagates to more and more header files, this triggers when building without checking. How do you suggest that we try to fix it this time? I'm not certain that we can pull out the one function this time. Should we return to the -frandom-seed patch for self-test files that you proposed last time? Thanks, David
