And recently they moved to ll/sc instruction emulation. Well, you seem to have a different linux-vr tree than I do :-) > Ralf, the following patch includes the original vr code for > MIPS_ATOMIC_SET, no ll/sc case. Although we all know it is buggy (for > small negative set values), it is still better than nothing. Anyway, the linux-vr source tree has a partially working ll/sc emulation, at least enough for glibc, and MIPS_ATOMIC_SET is not neccessarily needed. In fact, MIPS_ATOMIC_SET has been removed from the vr tree. Regards, Harald
