87 | /* ppc_linux_memory_remove_breakpoints attempts to remove a breakpoint |
88 | in much the same fashion as memory_remove_breakpoint in mem-break.c, | |
89 | but is careful not to write back the previous contents if the code | |
90 | in question has changed in between inserting the breakpoint and | |
91 | removing it. | |
92 | ||
93 | Here is the problem that we're trying to solve... | |
94 | ||
95 | Once upon a time, before introducing this function to remove | |
96 | breakpoints from the inferior, setting a breakpoint on a shared | |
97 | library function prior to running the program would not work | |
98 | properly. In order to understand the problem, it is first | |
99 | necessary to understand a little bit about dynamic linking on | |
100 | this platform. | |
101 | ||
102 | A call to a shared library function is accomplished via a bl | |
103 | (branch-and-link) instruction whose branch target is an entry | |
104 | in the procedure linkage table (PLT). The PLT in the object | |
105 | file is uninitialized. To gdb, prior to running the program, the | |
106 | entries in the PLT are all zeros. | |
107 | ||
108 | Once the program starts running, the shared libraries are loaded | |
109 | and the procedure linkage table is initialized, but the entries in | |
110 | the table are not (necessarily) resolved. Once a function is | |
111 | actually called, the code in the PLT is hit and the function is | |
112 | resolved. In order to better illustrate this, an example is in | |
113 | order; the following example is from the gdb testsuite. | |
114 | ||
115 | We start the program shmain. | |
116 | ||
117 | [kev@arroyo testsuite]$ ../gdb gdb.base/shmain | |
118 | [...] | |
119 | ||
120 | We place two breakpoints, one on shr1 and the other on main. | |
121 | ||
122 | (gdb) b shr1 | |
123 | Breakpoint 1 at 0x100409d4 | |
124 | (gdb) b main | |
125 | Breakpoint 2 at 0x100006a0: file gdb.base/shmain.c, line 44. | |
126 | ||
127 | Examine the instruction (and the immediatly following instruction) | |
128 | upon which the breakpoint was placed. Note that the PLT entry | |
129 | for shr1 contains zeros. | |
130 | ||
131 | (gdb) x/2i 0x100409d4 | |
132 | 0x100409d4 <shr1>: .long 0x0 | |
133 | 0x100409d8 <shr1+4>: .long 0x0 | |
134 | ||
135 | Now run 'til main. | |
136 | ||
137 | (gdb) r | |
138 | Starting program: gdb.base/shmain | |
139 | Breakpoint 1 at 0xffaf790: file gdb.base/shr1.c, line 19. | |
140 | ||
141 | Breakpoint 2, main () | |
142 | at gdb.base/shmain.c:44 | |
143 | 44 g = 1; | |
144 | ||
145 | Examine the PLT again. Note that the loading of the shared | |
146 | library has initialized the PLT to code which loads a constant | |
147 | (which I think is an index into the GOT) into r11 and then | |
148 | branchs a short distance to the code which actually does the | |
149 | resolving. | |
150 | ||
151 | (gdb) x/2i 0x100409d4 | |
152 | 0x100409d4 <shr1>: li r11,4 | |
153 | 0x100409d8 <shr1+4>: b 0x10040984 <sg+4> | |
154 | (gdb) c | |
155 | Continuing. | |
156 | ||
157 | Breakpoint 1, shr1 (x=1) | |
158 | at gdb.base/shr1.c:19 | |
159 | 19 l = 1; | |
160 | ||
161 | Now we've hit the breakpoint at shr1. (The breakpoint was | |
162 | reset from the PLT entry to the actual shr1 function after the | |
163 | shared library was loaded.) Note that the PLT entry has been | |
0df8b418 | 164 | resolved to contain a branch that takes us directly to shr1. |
122a33de KB |
165 | (The real one, not the PLT entry.) |
166 | ||
167 | (gdb) x/2i 0x100409d4 | |
168 | 0x100409d4 <shr1>: b 0xffaf76c <shr1> | |
169 | 0x100409d8 <shr1+4>: b 0x10040984 <sg+4> | |
170 | ||
171 | The thing to note here is that the PLT entry for shr1 has been | |
172 | changed twice. | |
173 | ||
174 | Now the problem should be obvious. GDB places a breakpoint (a | |
0df8b418 | 175 | trap instruction) on the zero value of the PLT entry for shr1. |
122a33de KB |
176 | Later on, after the shared library had been loaded and the PLT |
177 | initialized, GDB gets a signal indicating this fact and attempts | |
178 | (as it always does when it stops) to remove all the breakpoints. | |
179 | ||
180 | The breakpoint removal was causing the former contents (a zero | |
181 | word) to be written back to the now initialized PLT entry thus | |
182 | destroying a portion of the initialization that had occurred only a | |
183 | short time ago. When execution continued, the zero word would be | |
766062f6 | 184 | executed as an instruction an illegal instruction trap was |
122a33de KB |
185 | generated instead. (0 is not a legal instruction.) |
186 | ||
187 | The fix for this problem was fairly straightforward. The function | |
188 | memory_remove_breakpoint from mem-break.c was copied to this file, | |
189 | modified slightly, and renamed to ppc_linux_memory_remove_breakpoint. | |
190 | In tm-linux.h, MEMORY_REMOVE_BREAKPOINT is defined to call this new | |
191 | function. | |
192 | ||
193 | The differences between ppc_linux_memory_remove_breakpoint () and | |
194 | memory_remove_breakpoint () are minor. All that the former does | |
195 | that the latter does not is check to make sure that the breakpoint | |
196 | location actually contains a breakpoint (trap instruction) prior | |
197 | to attempting to write back the old contents. If it does contain | |
0df8b418 | 198 | a trap instruction, we allow the old contents to be written back. |
122a33de KB |
199 | Otherwise, we silently do nothing. |
200 | ||
201 | The big question is whether memory_remove_breakpoint () should be | |
202 | changed to have the same functionality. The downside is that more | |
203 | traffic is generated for remote targets since we'll have an extra | |
204 | fetch of a memory word each time a breakpoint is removed. | |
205 | ||
206 | For the time being, we'll leave this self-modifying-code-friendly | |
207 | version in ppc-linux-tdep.c, but it ought to be migrated somewhere | |
208 | else in the event that some other platform has similar needs with | |
209 | regard to removing breakpoints in some potentially self modifying | |
210 | code. */ | |
