LD: Always make a SEGMENT_START expression section-relative Fix an issue with the SEGMENT_START builtin function where its result is absolute when taken from the default supplied, and section-relative when taken from a `-T' command-line override. This is against documentation, inconsistent and unexpected, and with PIE executables gives an incorrect result with the `__executable_start' symbol. Make the result of SEGMENT_START always section-relative then. ld/ * ldexp.c (fold_binary): Always make the result of SEGMENT_START section-relative. * testsuite/ld-scripts/segment-start.d: New test. * testsuite/ld-scripts/segment-start.ld: New test linker script. * testsuite/ld-scripts/segment-start.s: New test source. * testsuite/ld-scripts/script.exp: Run the new test. 2018-09-15 03:22:56 +08:00			`SECTIONS`
