2013-06-21Update dates in relevant gdb/gnulib/ copyright headersJoel Brobecker4-3/+9
This patch is the result of re-running the copyright.py script in GDB, after we modified it to stop ignoring some files in gdb/gnulib that should have been updated earlier this year. gdb/ChangeLog: * gdb/gnulib/Makefile.in: Update date in copyright header. * gdb/gnulib/configure.ac: Ditto. * gdb/gnulib/update-gnulib.sh: Ditto.

The script was excluding all of gdb/gnulib but this is no longer correct, ever since we moved the imported files to gdb/gnulib/import. As a result, a number of files (Makefile, etc, including this script itself) did not have their copyright header updated.

2013-06-19gdb: clean up x86 cpuid implementationsMike Frysinger11-70/+231
We've currently got 3 files doing open coded implementations of cpuid. Each has its own set of workarounds and varying levels of how well they're written and are generally hardcoded to specific cpuid functions. If you try to build the latest gdb as a PIE on an i386 system, the build will fail because one of them lacks PIC workarounds (wrt ebx). Specifically, we have: common/linux-btrace.c: two copies of cpuid asm w/specific args, one has no workarounds while the other implicitly does to avoid memcpy go32-nat.c: two copies of cpuid asm w/specific args, one has workarounds to avoid memcpy gdb/testsuite/gdb.arch/i386-cpuid.h: one general cpuid asm w/many workarounds copied from older gcc Fortunately, that last header there is pretty damn good -- it handles lots of edge cases, the code is nice & tight (uses gcc asm operands rather than manual movs), and is already almost a general library type header. It's also the basis of what is now the public cpuid.h that is shipped with gcc-4.3+. So what I've done is pull that test header out and into gdb/common/ (not sure if there's a better place), synced to the version found in gcc-4.8.0, put a wrapper API around it, and then cut over all the existing call points to this new header. Since the func already has support for "is cpuid supported on this proc", it makes it trivial to push the i386/x86_64 ifdefs down into this wrapper API too. Now it can be safely used for all targets and gcc will elide the unused code for us. I've verified the gdb.arch testsuite still passes, and this code compiles for an armv7a host as well as x86_64. The go32-nat code has been left ifdef-ed out until someone can test & verify the new stuff works (and if it doesn't, figure out how to make the new code work).

We wrote a test case that tries every single 32bit opcode on the hardware and compared it to the sim. There were a bunch of places in the sim where we weren't strict enough (requiring certain parts of the opcode be set) so we were treating a lot of invalid opcodes as valid ones. This sprinkles out a lot additional checks in the dsp32alu class. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

2013-06-18[Darwin] Fix cleanup leak in machoread.c:macho_symfile_readJoel Brobecker2-26/+35
This patch fixes a cleanup leak in macho_symfile_read (symbol_table): symbol_table = (asymbol **) xmalloc (storage_needed); make_cleanup (xfree, symbol_table); Unfortunately, fixing the leak alone triggers a crash which occurs while loading the symbols from an executable: % gdb (gdb) file g_exe [SIGSEGV] The crash is caused by the fact that performing the cleanup right after the call to macho_symtab_read, as currently done, is too early. Indeed, references to this symbol_table get saved in the oso_vector global during the call to macho_symtab_read via calls to macho_register_oso, and those references then get accessed later on, when processing all the OSOs that got pushed (see call to macho_symfile_read_all_oso). This patch prevents this by using one single cleanup queue for the entire function, rather than having additional separate cleanup queues (Eg: for the handling of the minimal symbols), thus preventing the premature free'ing of the minimal_symbols array. Secondly, this patch takes this opportunity for avoiding the use of the oso_vector global, thus making it simpler to track its lifetime. gdb/ChangeLog: * machoread.c (oso_vector): Delete this global. (macho_register_oso): Add new parameter "oso_vector_ptr". Use it instead of the "oso_vector" global. (macho_symtab_read, macho_symfile_read_all_oso): Likewise. (macho_symfile_read): Use a local oso_vector, to be free'ed at the end of this function, in place of the old "oso_vector" global. Update various function calls accordingly. Use one single cleanup chain for the entire function.
2013-06-18do not use dwarf2_per_objfile in dwarf2_per_objfile_free.Joel Brobecker2-6/+10
This patch fixes a case of multiple calls freeing the same data while free-ing objfiles that have child objfiles (separate debug info, as is the case on Darwin targets). Following the code, free_objfile_separate_debug iterates over all child objfiles of the parent objfile, calling free_objfile: for (child = objfile->separate_debug_objfile; child;) { struct objfile *next_child = child->separate_debug_objfile_link; free_objfile (child); child = next_child; } This causes, among other things, the free'ing of the child objfile's private data: /* Discard any data modules have associated with the objfile. The function still may reference objfile->obfd. */ objfile_free_data (objfile); This indirectly calls(back) dwarf2_per_objfile_free, which tries to free the dwarf2read-specific data by using the dwarf2_per_objfile global, eg: for (ix = 0; ix < dwarf2_per_objfile->n_comp_units; ++ix) Even if we were lucky enough the first time around that this global actually corresponds to the objfile being destroyed, the global will still have the same value at the second iteration, and thus become dangling. Indeed, after dwarf2_per_objfile_free returns eventually back to free_objfile, free_objfile then deallocates its objfile_obstack, where the dwarf2_per_objfile is allocated. Ironically, there should be no need to access that global at all, here, since the data is passed as an argument of the callback. And it looks like the dwo/dwp/[...]-handling code is in fact already using that argument, rather than the global. This patch thus fixes the problem by doing the same, replacing all references to DWARF2_PER_OBJFILE by uses of DATA instead. gdb/ChangeLog: * dwarf2read.c (dwarf2_per_objfile): Replace uses of DWARF2_PER_OBJFILE by uses of DATA instead.
2013-06-18Fix PR cli/15603Tom Tromey8-14/+138
This fixes PR cli/15603. The bug here is that when a software watchpoint is being used, gdb will stop responding to C-c. This is a regression caused by the "catch signal" patch. The problem is that software watchpoints always end up on the bpstat list. However, this makes bpstat_explains_signal return BPSTAT_SIGNAL_HIDE, causing infrun to think that the signal is not a "random signal". The fix is to change bpstat_explains_signal to handle this better. I chose to do it in a "clean API" way, by passing the signal value to bpstat_explains_signal and then adding an explains_signal method for watchpoints, which handles the specifics. Built and regtested on x86-64 Fedora 18. New test case included. * break-catch-sig.c (signal_catchpoint_explains_signal): Add 'sig' argument. * breakpoint.c (bpstat_explains_signal): Add 'sig' argument. Special case signals other than GDB_SIGNAL_TRAP. (explains_signal_watchpoint): New function. (base_breakpoint_explains_signal): Add 'sig' argument. (initialize_breakpoint_ops): Set 'explains_signal' method for watchpoints. * breakpoint.h (struct breakpoint_ops) <explains_signal>: Add signal argument. (bpstat_explains_signal): Likewise. * infrun.c (handle_syscall_event, handle_inferior_event): Update. * gdb.base/random-signal.c: New file. * gdb.base/random-signal.exp: New file.
