Good evening, cleanup and testing further with linux-2.4.37.11 kernel compilation: include/asm-i386/spinlock.h includes include/asm-i386/rwlock.h
While parsing valid x86 inline asm with tcc (latest mob branch HEAD) linux/include/asm/spinlock.h:197: error: bad expression syntax [%] This change to kernel source merely circuumvents the compile-time parsing error: #define __build_write_lock_const(rw, helper) \ - asm volatile(LOCK "subl $" RW_LOCK_BIAS_STR ",(%0)\n\t" \ + asm volatile(LOCK "subl $" RW_LOCK_BIAS_STR ",%0\n\t" \ However, although this prevents the parsing error, the intermediate change to kernel source applied probably causes incorrect run-time behaviour (while testing SMP/IOAPIC that probably does rely upon locking and sporadically panics while booting with smp enabled, not sure yet.) Help would be appreciated: - if and how the inline assembly part could be re-written for tcc compatibility that retains correct behaviour of the code - and/or a patch to tcc to process valid inline assembly without a parsing error thrown Thanks. --
