[i386] Add explicit ""aw", @nobits" declarations to stack sections As reported by Stefan, commit 13d09e6 ("[i386] Simplify linker script and standardise linker-defined symbol names") breaks gdb, readelf and associated utilities. This is caused by the .stack section overwriting a block in the middle of the .debug_info section (despite being included in the .bss.textdata section in the output file, which apparently has the correct attributes for a .bss section). Fixed by adding explicit flags and type to the stack section declaration. 2009-02-15 10:02:26 +00:00			`.section ".stack16", "aw", @nobits`
[build] Use .balign directive instead of .align The semantics of the assembler's .align directive vary by CPU architecture. For the ARM builds, it specifies a power of two rather than a number of bytes. This currently leads to the .einfo entries (which do not appear in the final binary) having an alignment of 256 bytes for the ARM builds. Fix by switching to the GNU-specific directive .balign, which is consistent across architectures Signed-off-by: Michael Brown <mcb30@ipxe.org> 2021-02-12 23:22:54 +00:00			`.balign 8`
