Description Török Edwin 2009-09-05 02:10:11 PDT 
valgrind 3.4.1 doesn't compile:

m_signals.c:1435:7: error: cannot compile this builtin function yet
      __builtin_longjmp(tst->sched_jmpbuf, True);
      ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Comment 1 Török Edwin 2009-09-05 02:11:28 PDT 
m_scheduler/scheduler.c:824:4: error: cannot compile this builtin function yet
   SCHEDSETJMP(tid, jumped, VG_(client_syscall)(tid));
   ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
m_scheduler/scheduler.c:519:18: note: instantiated from:
      (jumped) = __builtin_setjmp(_qq_tst->sched_jmpbuf);               \
                 ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Comment 2 Török Edwin 2010-04-24 03:06:04 PDT 
This is still an issue for clang 2.7
Comment 3 Jim Grosbach 2010-05-26 15:23:42 PDT 
Enabling the code in CGBuiltin.cpp to handle these works on ARM/Darwin. No other targets lower the intrinsics that I know of, though.
Comment 4 Chris Lattner 2012-10-17 14:58:09 PDT 
This is theoretically fixed in r165989.  Please verify.
