Third attempt at unifying the various GCC linker scripts for different architectures, GCC versions and minimum alignments.
Changes since v2: - for easier bisection, factor out the differences between the original and the unified linker scripts for X86 before making the switch (patches #1 - #4 and #6) - add Intel copyright notice to unified version (patch #5) - avoid defining *_*_*_DLINK2_FLAGS so that we don't pollute the variable definition space of non-GCC toolchains (patches #8 and #12) - added Laszlo's ack to patch #10 ---------------------------- v2 blurb --------------------------------- This time, I have added only a single unified GCC linker script that can be parametrised by ld command line options: - --defsym=PECOFF_HEADER_SIZE sets the size of the PE/COFF header - -z common-page-size sets the minimum alignment This use of common-page-size is entirely legal: it sets an internal LD constant which can be referred to as CONSTANT(COMMONPAGESIZE) in linker scripts, and is otherwise unused internally by the linker.
