Dear Albert ARIBAUD,
In message 4CF7583C.7000001@free.fr you wrote:
Does it help when you change the "*(.bss)" in "arch/arm/cpu/armv7/u-boot.lds" into "*(.*bss)" (so it also includes any .sbss objects) ?
No change.
Hm... Maybe it is indeed not a good idea to mix short objects with those requiring larger alignments - we might lose space at best, or case misaligned variables? Eventually it's better to explicitly write
*(.bss*) *(.sbss*)
as we have it in many PowerPC linker scripts (but I have to admit that I don't know if this is really needed - I don't see any .sbss anywhere in this build (I do see them in some objects for PowerPC). For example:
PowerPC:
-> readelf -S common/dlmalloc.o | grep bss [ 3] .bss NOBITS 00000000 000034 000000 00 WA 0 0 1 [36] .bss.n_mmaps_max NOBITS 00000000 002728 000004 00 WA 0 0 4 [37] .sbss.mem_malloc_ NOBITS 00000000 002728 000004 00 WA 0 0 4 [38] .bss.max_total_me NOBITS 00000000 002728 000004 00 WA 0 0 4 [40] .bss.max_sbrked_m NOBITS 00000000 00272c 000004 00 WA 0 0 4 [43] .bss.top_pad NOBITS 00000000 002734 000004 00 WA 0 0 4 [44] .sbss.mem_malloc_ NOBITS 00000000 002734 000004 00 WA 0 0 4 [45] .sbss.mem_malloc_ NOBITS 00000000 002734 000004 00 WA 0 0 4 [46] .bss.current_mall NOBITS 00000000 002734 000028 00 WA 0 0 4
ARM:
-> readelf -S common/dlmalloc.o | grep bss [ 5] .bss NOBITS 00000000 0015e0 000044 00 WA 0 0 4
