| |
Hi Andrew,
for the kernel, it would be logical to use -ffreestanding. The kernel is not a hosted environment with a standard C library.
Linus agreed that it would make sense.
The gcc option -ffreestanding is supported by both gcc 2.95 and 3.4, which covers the whole range of currently supported compilers.
Could you add the patch below to the next -mm to see whether there are any problems I didn't find?
TIA Adrian
