35 /* This structure maintains information on a per-objfile basis about the
36 "entry point" of the objfile, and the scope within which the entry point
37 exists. It is possible that gdb will see more than one objfile that is
38 executable, each with its own entry point.
40 For example, for dynamically linked executables in SVR4, the dynamic linker
41 code is contained within the shared C library, which is actually executable
42 and is run by the kernel first when an exec is done of a user executable
43 that is dynamically linked. The dynamic linker within the shared C library
44 then maps in the various program segments in the user executable and jumps
45 to the user executable's recorded entry point, as if the call had been made
46 directly by the kernel.
48 The traditional gdb method of using this info was to use the
49 recorded entry point to set the entry-file's lowpc and highpc from
50 the debugging information, where these values are the starting
51 address (inclusive) and ending address (exclusive) of the
52 instruction space in the executable which correspond to the
53 "startup file", i.e. crt0.o in most cases. This file is assumed to
54 be a startup file and frames with pc's inside it are treated as
55 nonexistent. Setting these variables is necessary so that
56 backtraces do not fly off the bottom of the stack.
58 NOTE: cagney/2003-09-09: It turns out that this "traditional"
59 method doesn't work. Corinna writes: ``It turns out that the call
60 to test for "inside entry file" destroys a meaningful backtrace
61 under some conditions. E.g. the backtrace tests in the asm-source
62 testcase are broken for some targets. In this test the functions
63 are all implemented as part of one file and the testcase is not
64 necessarily linked with a start file (depending on the target).
65 What happens is, that the first frame is printed normaly and
66 following frames are treated as being inside the enttry file then.
67 This way, only the #0 frame is printed in the backtrace output.''
68 Ref "frame.c" "NOTE: vinschen/2003-04-01".
70 Gdb also supports an alternate method to avoid running off the bottom
73 There are two frames that are "special", the frame for the function
74 containing the process entry point, since it has no predecessor frame,
75 and the frame for the function containing the user code entry point
76 (the main() function), since all the predecessor frames are for the
77 process startup code. Since we have no guarantee that the linked
78 in startup modules have any debugging information that gdb can use,
79 we need to avoid following frame pointers back into frames that might
80 have been built in the startup code, as we might get hopelessly
81 confused. However, we almost always have debugging information
84 These variables are used to save the range of PC values which are
85 valid within the main() function and within the function containing
86 the process entry point. If we always consider the frame for
87 main() as the outermost frame when debugging user code, and the
88 frame for the process entry point function as the outermost frame
89 when debugging startup code, then all we have to do is have
90 DEPRECATED_FRAME_CHAIN_VALID return false whenever a frame's
91 current PC is within the range specified by these variables. In
92 essence, we set "ceilings" in the frame chain beyond which we will
93 not proceed when following the frame chain back up the stack.
95 A nice side effect is that we can still debug startup code without
96 running off the end of the frame chain, assuming that we have usable
97 debugging information in the startup modules, and if we choose to not
98 use the block at main, or can't find it for some reason, everything
99 still works as before. And if we have no startup code debugging
100 information but we do have usable information for main(), backtraces
101 from user code don't go wandering off into the startup code. */

643 expressions, such as if the inner loop has reached its end, so
644 the check mentioned above succeeds the first time.
646 - The trick to not clearing OBJFILE on a "break;" is, in the outer
647 loop's loop expression, advance OBJFILE, but iff the inner loop
648 reached its end. If not, there was a "break;", so leave OBJFILE
