--- Comment #9 from Rainer Orth <ro at gcc dot gnu.org> --- Created attachment 38413 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=38413&action=edit sparcv9 support patch This patch (on top of the previous one) fixes the sparcv9 failures reported before. As I'd suspected, the problem was that the code didn't take the SPARC V9 stack bias into account: in a couple of places, the stack and frame pointers in the __builtin_setjmp/__builtin_longjmp internal jmpbuf are overwritten with unbiased addresses. The patch includes both debugging code (assertions to check that the stack pointer is either biased or unbiased) and CILK_ADJUST_SP/CILK_UNADJUST_SP macros to turn a stack pointer from unbiased to biased form. The patch is enough to successfully run all Cilk Plus in the gcc and g++ testsuites successfully on sparc-sun-solaris2.10, but there may be code paths that also need adjustments. I'm just posting the patch (which is relative to upstream libcilkrts, which should be merged into mainline any day now) for reference and comments. Rainer
