2014-12-03callback.h:struct host_callback_struct compilation error on Windows hosts.Joel Brobecker9-11/+38
On Windows, a recent gnulib update imported the lstat module, and this caused a remote-sim.c build failure in struct host_callback_struct: In file included from /[...]/gdb/remote-sim.c:34:0: /[...]/gdb/../include/gdb/callback.h:93:9: error: duplicate member '_stati64' int (*lstat) (host_callback *, const char *, struct stat *); ^ What happens it that gnulib's stat.h makes the following defines: /* Large File Support on native Windows. */ #if 1 # define stat _stati64 #endif and then: #if 1 # if ! 0 /* mingw does not support symlinks, therefore it does not have lstat. But without links, stat does just fine. */ # if !(defined __cplusplus && defined GNULIB_NAMESPACE) # define lstat stat # endif So, the following fields in struct host_callback_struct... int (*stat) (host_callback *, const char *, struct stat *); int (*fstat) (host_callback *, int, struct stat *); int (*lstat) (host_callback *, const char *, struct stat *); ... get translated to... int (*_stati64) (host_callback *, const char *, struct _stati64 *); int (*_fstati64) (host_callback *, int, struct _stati64 *); int (*_stati64) (host_callback *, const char *, struct _stati64 *); ... which causes two fields to have the same name.

For my standard benchmark this patch gets back 44MB of memory when gdb starts. [There's still ~440MB of memory used by the demangled ELF symbols of this benchmark, but that's another topic.] When the improved templated support is added, I wonder if this can be moved to struct symbol.

2014-12-02execl-update-breakpoints.exp: Move whole segment instead of .text sectionAndreas Arnez2-8/+28
The test case builds two copies of the program, one with the compile option "ldflags=-Wl,-Ttext=0x1000000" and the other with the address changed to 0x2000000. However, when linking with ld.bfd, the resulting executables crash early in ld.so on S390 and i386. Analysis of the crash: The default linker script establishes a certain order of loadable sections, and the option "-Ttext" effectively splits these into an "unaffected" lot (everything before .text) and an "affected" lot. The affected lot is placed at the given address, whereas the unaffected lot stays at its default address. The unaffected lot starts at an aligned address plus Elf header sizes, which is good if it is the first LOAD segment (like on AMD64). But if the affected lot comes first instead (like on S390 and i386), the PHDR doesn't fit there and is placed *outside* any LOAD segments. Then the PHDR is not mapped when the loader gets control, and the loader runs into a segmentation fault while trying to access it. Since we are lucky about the order of segments on AMD64, the test succeeds there, but the resulting binaries are unusually large -- 2.1M each, with lots of padding within. When replacing '-Ttext' by '-Ttext-segment', the linker moves all segments consistently, the binaries have normal sizes, and the test case succeeds on all mentioned platforms. Since old versions of the gold linker don't support '-Ttext-segment', the patch also adds logic for falling back to '-Ttext'. gdb/testsuite/ChangeLog: * gdb.base/execl-update-breakpoints.exp: Specify the link address with '-Ttext-segment' instead of '-Ttext'. Fall back to '-Ttext' if the linker doesn't understand this.

PR gold/17578 notes that gold will print a warning about an executable stack when the -z execstack option is given, even when there is no --warn_execstack option. The warning is completely useless and unexpected, since the user explicitly requested an executable stack, and did not even ask for warnings.

Therefore ABRT needs to use -iex parameters to add this /var/cache/abrt-di/ directory as a first-class debuginfo directory.
