63 
64  The resulting executables will still run without Valgrind, just a
65  little bit more slowly than they otherwise would, but otherwise
66  unchanged. When not running on valgrind, each client request
67  consumes very few (eg. 7) instructions, so the resulting performance
68  loss is negligible unless you plan to execute client requests
69  millions of times per second. Nevertheless, if that is still a
70  problem, you can compile with the NVALGRIND symbol defined (gcc
71  -DNVALGRIND) so that client requests are not even compiled in. */

132  _zzq_rlval, _zzq_default, _zzq_request, \
133  _zzq_arg1, _zzq_arg2, _zzq_arg3, _zzq_arg4, _zzq_arg5) \

140 /* The following defines the magic code sequences which the JITter
141  spots and handles magically. Don't look too closely at them as
142  they will rot your brain.
143 
144  The assembly code sequences for all architectures is in this one
145  file. This is because this file must be stand-alone, and we don't
146  want to have multiple files.
147 
148  For VALGRIND_DO_CLIENT_REQUEST, we must ensure that the default
149  value gets put in the return slot, so that everything works when
150  this is executed not under Valgrind. Args are passed in a memory
151  block, and so there's no intrinsic limit to the number that could
152  be passed, but it's currently five.
153 
154  The macro args are:
155  _zzq_rlval result lvalue
156  _zzq_default default value (result returned when running on real CPU)
157  _zzq_request request code
158  _zzq_arg1..5 request params
159 
160  The other two macros are used to support function wrapping, and are
161  a lot simpler. VALGRIND_GET_NR_CONTEXT returns the value of the
162  guest's NRADDR pseudo-register and whatever other information is
163  needed to safely run the call original from the wrapper: on
164  ppc64-linux, the R2 value at the divert point is also needed. This
165  information is abstracted into a user-visible type, OrigFn.
166 
167  VALGRIND_CALL_NOREDIR_* behaves the same as the following on the
168  guest, but guarantees that the branch instruction will not be
169  redirected: x86: call *%eax, amd64: call *%rax, ppc32/ppc64:
170  branch-and-link-to-r11. VALGRIND_CALL_NOREDIR is just text, not a
171  complete inline asm, since it needs to be combined with more magic
172  inline asm stuff to be useful.

1025 /* NB 9 Sept 07. There is a nasty kludge here in all these CALL_FN_
1026  macros. In order not to trash the stack redzone, we need to drop
1027  %rsp by 128 before the hidden call, and restore afterwards. The
1028  nastyness is that it is only by luck that the stack still appears
1029  to be unwindable during the hidden call - since then the behaviour
1030  of any routine using this macro does not match what the CFI data
1031  says. Sigh.
1032 
1033  Why is this important? Imagine that a wrapper has a stack
1034  allocated local, and passes to the hidden call, a pointer to it.
1035  Because gcc does not know about the hidden call, it may allocate
1036  that local in the redzone. Unfortunately the hidden call may then
1037  trash it before it comes to use it. So we must step clear of the
1038  redzone, for the duration of the hidden call, to make it safe.
1039 
1040  Probably the same problem afflicts the other redzone-style ABIs too
1041  (ppc64-linux, ppc32-aix5, ppc64-aix5); but for those, the stack is
1042  self describing (none of this CFI nonsense) so at least messing
1043  with the stack pointer doesn't give a danger of non-unwindable
1044  stack. */
