x86, realmode: Add .text64 section, make barrier symbols absolute (487f50ff) · Commits · 戴 / test

Add a .text64 section. The purpose of this is to keep 16-, 32- and 64-bit code segregated into separate sections, mainly to keep disassembly sane. Move barrier symbols out of sections to avoid the "symbol in empty section" problem in some versions of GNU ld. Signed-off-by:
