Hi,
Trying to compile i386 kernel with CONFIG_HIGHMEM64G=y using gcc-2.7.2.3
I observe problem with some inline functions:
mm/mm.o: In function `vmalloc_area_pages':
mm/mm.o(.text+0xad18): undefined reference to `set_pgdir'
mm/mm.o: In function `__vmalloc':
mm/mm.o(.text+0xb41d): undefined reference to `set_pgdir'
mm/mm.o: In function `swap_out_vma':
mm/mm.o(.text+0xcfeb): undefined reference to `pgd_bad'
mm/mm.o: In function `unuse_vma':
mm/mm.o(.text+0xe944): undefined reference to `pgd_bad'
fs/fs.o: In function `statm_pgd_range':
fs/fs.o(.text+0x1dfa6): undefined reference to `pgd_bad'
drivers/char/drm/drm.o: In function `_drm_vma_info':
drivers/char/drm/drm.o(.text+0x26ba): undefined reference to `pte_young'
drivers/char/drm/drm.o(.text+0x26d7): undefined reference to `pte_dirty'
drivers/char/drm/drm.o(.text+0x26f4): undefined reference to `pte_exec'
drivers/char/drm/drm.o(.text+0x2711): undefined reference to `pte_write'
drivers/char/drm/drm.o(.text+0x272e): undefined reference to `pte_read'
make: *** [vmlinux] Error 1
nm mm/memory.o shows:
00000004 C num_physpages
U pager_daemon
000024a8 t partial_clear
U pgd_bad <---------- shouldn't happen for inline function
00000004 D pgt_cache_water
U printk
U read_swap_cache_async
I see that problem is with inline functions with 64-bit arguments.
Converting the inlines to operate on pointers seems to fix this problem.
Is it the right way to fix them? (It should be cheap)
Or:
- should they be converted to non-inlines (expensive)
- should gcc-2.7.2.3 be dropped (eventually dropped for some config options)
?
Regards
Andrzej
