Remove lrecord_type_popup_data, lrecord_type_window_configuration, .gdbinit.in
2010-11-15 Aidan Kehoe <kehoea@parhasard.net>
* .gdbinit.in: Remove lrecord_type_popup_data,
lrecord_type_window_configuration from this file, they're not
used, and their presence breaks pobj in GDB at runtime for me.

19 dnl Boston, MA 02110-1301, USA. |
| 388 | 20 dnl |
| 21 dnl There are several things we care about here. First, we need to find | |
| 22 dnl out how we create an executable that has its symbols exported, so | |
| 23 dnl that dynamically loaded modules have access to the internal XEmacs | |
| 24 dnl symbols. This is stored in ``ld_dynamic_link_flags'' and is used | |
| 25 dnl in the main Makefile. | |
| 26 dnl Next, we need to know how we compile actual shared libraries, and | |
| 27 dnl the objects in them. For these purposes, we need to determine the | |
| 28 dnl C compiler flags used to produce shared objects (``dll_cflags''), | |
| 29 dnl what linker to use to create the final shared object that will be | |
| 30 dnl loaded (``dll_ld'') and the flags to pass to that linker | |
| 31 dnl (``dll_ldflags''). This information is used by ellcc to build up | |
| 32 dnl the command line when compiling modules. We build up two other commands | |
| 33 dnl for extremely weird systems where special things need to be done. | |
| 34 dnl The first is ``dll_ldo'', which is the flag used to specify the output | |
| 35 dnl file name, and the second is ``dll_post'' which is inserted after the | |
| 36 dnl list of objects. | |
| 37 dnl After all of this, we should be able to: | |
| 38 dnl $(CC) $(CFLAGS) $(dll_cflags) -c module.c | |
| 39 dnl to produce a single shared object | |
| 40 dnl And then: | |
| 41 dnl $(dll_ld) $(dll_ldflags) $(dll_ldo) module.ell module.o $(dll_post) | |
| 42 dnl to create the loadable shared library. | |
| 43 dnl | |
| 44 dnl NOTE: In the code below, where I have modified things to work with | |
| 45 dnl XEmacs, we use $canonical instead of libtool's $host, and we use | |
| 46 dnl $internal_configuration instead of $host_alias. To make typing | |
| 47 dnl shorter we assign these to $xehost and $xealias | |

| 202 dnl | |
| 203 dnl Now comes the LD trickery. We do things differently to libtool here. | |
| 204 dnl I believe that libtool is incorrect in trying to drive the linker | |
| 205 dnl directly. This can cause considerable problems if the module you are | |
| 206 dnl compiling has C++ or other static initializers. If we use ld directly, | |
| 442 | 207 dnl we don't end up with the crt stuff being linked in, and we don't end up |
| 388 | 208 dnl with any .init or .fini sections (or the moral equivalent thereof). |
| 442 | 209 dnl gcc takes great care to do this properly when invoked in -shared |
| 210 dnl mode, and we really do want this behavior. Perhaps the libtool folks | |
| 388 | 211 dnl are not aware that any SVR4 based dynamic loader will automatically |
| 212 dnl execute code in the .init section before dlopen() returns. This is | |
| 442 | 213 dnl vital, as the module may have been compiled to rely on that behavior. |
| 388 | 214 dnl |
| 215 dnl So, having said all of that, we diverge from libtool significantly | |
| 216 dnl here. We want to try and use the C compiler as much as possible. Only | |
| 2079 | 217 dnl if the C compiler itself cannot create shared libraries do we try to |
| 388 | 218 dnl find the linker. |
| 219 dnl | |
| 220 dnl The other advantage to my scheme is that it removes the dependancy | |
| 221 dnl on a given compiler version remaining static with relation to the | |
| 222 dnl version of XEmacs. With the libtool way, it picks up the linker that | |
| 223 dnl gcc uses, which can be the internal collect2 that comes with gcc. | |
| 224 dnl If the user ever changes their compiler version, the paths will no | |
| 225 dnl longer be correct, and ellcc will break. This is clearly unacceptable. | |
| 442 | 226 dnl By using the compiler driver on the path, we don't have this problem. |
| 388 | 227 dnl If that is not clear, consider that gcc -print-prog-name=ld can |
| 228 dnl produce something along the lines of: | |
| 229 dnl /usr/local/lib/gcc-lib/OS-NAME/GCC-VERSION/ld | |
| 230 dnl If you ever change GCC versions, then that path no longer exists. | |
| 231 dnl | |
| 232 dnl So, we change the check order here. We first check to see if we are | |
| 233 dnl using GCC, and if so, we see if -shared works. If it does, great. | |
| 234 dnl If we are not using gcc, but the system C compiler can produce | |
| 235 dnl shared objects, we try that. Only if all of that fails do we revert | |
| 236 dnl back to the libtool ld trickery. | |
| 237 dnl | |
| 442 | 238 dnl We don't do ANY of this if we can't produce shared objects. |
