155 | | /* The following defines the magic code sequences which the JITter |
156 | | spots and handles magically. Don't look too closely at them as |
157 | | they will rot your brain. |
158 | | |
159 | | The assembly code sequences for all architectures is in this one |
160 | | file. This is because this file must be stand-alone, and we don't |
161 | | want to have multiple files. |
162 | | |
163 | | For VALGRIND_DO_CLIENT_REQUEST, we must ensure that the default |
164 | | value gets put in the return slot, so that everything works when |
165 | | this is executed not under Valgrind. Args are passed in a memory |
166 | | block, and so there's no intrinsic limit to the number that could |
167 | | be passed, but it's currently five. |
168 | | |
169 | | The macro args are: |
170 | | _zzq_rlval result lvalue |
171 | | _zzq_default default value (result returned when running on real CPU) |
172 | | _zzq_request request code |
173 | | _zzq_arg1..5 request params |
174 | | |
175 | | The other two macros are used to support function wrapping, and are |
176 | | a lot simpler. VALGRIND_GET_NR_CONTEXT returns the value of the |
177 | | guest's NRADDR pseudo-register and whatever other information is |
178 | | needed to safely run the call original from the wrapper: on |
179 | | ppc64-linux, the R2 value at the divert point is also needed. This |
180 | | information is abstracted into a user-visible type, OrigFn. |
181 | | |
182 | | VALGRIND_CALL_NOREDIR_* behaves the same as the following on the |
183 | | guest, but guarantees that the branch instruction will not be |
184 | | redirected: x86: call *%eax, amd64: call *%rax, ppc32/ppc64: |
185 | | branch-and-link-to-r11. VALGRIND_CALL_NOREDIR is just text, not a |
186 | | complete inline asm, since it needs to be combined with more magic |
187 | | inline asm stuff to be useful. |

1040 | | /* NB 9 Sept 07. There is a nasty kludge here in all these CALL_FN_ |
1041 | | macros. In order not to trash the stack redzone, we need to drop |
1042 | | %rsp by 128 before the hidden call, and restore afterwards. The |
1043 | | nastyness is that it is only by luck that the stack still appears |
1044 | | to be unwindable during the hidden call - since then the behaviour |
1045 | | of any routine using this macro does not match what the CFI data |
1046 | | says. Sigh. |
1047 | | |
1048 | | Why is this important? Imagine that a wrapper has a stack |
1049 | | allocated local, and passes to the hidden call, a pointer to it. |
1050 | | Because gcc does not know about the hidden call, it may allocate |
1051 | | that local in the redzone. Unfortunately the hidden call may then |
1052 | | trash it before it comes to use it. So we must step clear of the |
1053 | | redzone, for the duration of the hidden call, to make it safe. |
1054 | | |
1055 | | Probably the same problem afflicts the other redzone-style ABIs too |
1056 | | (ppc64-linux, ppc32-aix5, ppc64-aix5); but for those, the stack is |
1057 | | self describing (none of this CFI nonsense) so at least messing |
1058 | | with the stack pointer doesn't give a danger of non-unwindable |
1059 | | stack. */ |
