It has nothing to do with the compiler, but everything to do with the C startup code. In the Linux kernel, we have complete control over the C startup code - it is in arch/*/kernel/head.S.
The only way a compiler can break this is if it creates a new section .bss_im_not_going_to_allow_anyone_to_initialise_this and places all the variables in there. Hardly likely, don't you think?
The initialisation of .bss is a run-time issue, NOT a compiler issue. _____ |_____| ------------------------------------------------- ---+---+- | | Russell King rmk@arm.linux.org.uk --- --- | | | | http://www.arm.linux.org.uk/personal/aboutme.html / / | | +-+-+ --- -+- / | THE developer of ARM Linux |+| /|\ / | | | --- | +-+-+ ------------------------------------------------- /\\\ | - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org Please read the FAQ at http://www.tux.org/lkml/
