* Add options to skip unavailable localsYao Qi2013-08-2712-27/+157
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is the patch to add new option '--skip-unavailable' to MI commands '-stack-list-{locals, arguments, variables}'. This patch extends list_args_or_locals to add a new parameter 'skip_unavailable', and don't list locals or arguments if values are unavailable and 'skip_unavailable' is true. This is inspecting a trace frame (tfind mode), where only a few locals have been collected. -stack-list-locals, no switch vs new switch: -stack-list-locals --simple-values ^done,locals=[{name="array",type="unsigned char [2]"},{name="i",type="int",value="<unavailable>"}] -stack-list-locals --skip-unavailable --simple-values ^done,locals=[{name="array",type="unsigned char [2]"}] -stack-list-arguments, no switch vs new switch: -stack-list-arguments --simple-values ^done,stack-args=[frame={level="0",args=[{name="j",type="int",value="4"},{name="s",type="char *",value="<unavailable>"}]},frame={level="1",args=[]}] -stack-list-arguments --skip-unavailable --simple-values ^done,stack-args=[frame={level="0",args=[{name="j",type="int",value="4"}]},frame={level="1",args=[]}] -stack-list-variables, no switch vs new switch: -stack-list-variables --simple-values ^done,variables=[{name="j",arg="1",type="int",value="4"},{name="s",arg="1",type="char *",value="<unavailable>"},{name="array",type="unsigned char [2]"},{name="i",type="int",value="<unavailable>"}] -stack-list-variables --skip-unavailable --simple-values ^done,variables=[{name="j",arg="1",type="int",value="4"},{name="array",type="unsigned char [2]"}] tests are added to test these new options. gdb: 2013-08-27 Pedro Alves <pedro@codesourcery.com> Yao Qi <yao@codesourcery.com> * mi/mi-cmd-stack.c (list_args_or_locals): Adjust prototype.

* fix dwz.exp on 32-bit targetsTom Tromey2013-08-223-6/+54
| | | | | | | | | | | | This fixes dwz.exp on 32-bit targets. It does so by introducing a new "default" setting for the address size in the DWARF assembler. Built and regtested on x86-64 Fedora 18. I also ran the gdb.dwarf2 tests on an x86 machine (gcc45). * lib/dwarf.exp (cu, tu): Handle addr_size of "default". Change default addr_size. * lib/gdb.exp (is_64_target): New gdb_caching_proc.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This fixes parts of gdb.arch to be parallel-safe. I only changed the bits I could test on this machine. I don't have access to many of the machines needed to fully switch gdb.arch; but I am happy to provide advice to others attempting this. Or, I can send an untested patch to convert it all.

* use standard_temp_file in another caching procTom Tromey2013-08-222-4/+8
| | | | | | | | | In an earlier patch I forgot to change the caching proc in cell.exp to use standard_temp_file. This fixes the oversight. Tested on x86-64 Fedora 18. * lib/cell.exp (skip_cell_tests): Use standard_temp_file.
* introduce gdb_remote_download and finish parallel fixes in gdb.dwarf2Tom Tromey2013-08-228-6/+34
| | | | | | | | | | | | | | | | | | | | | This finishes making gdb.dwarf2 parallel-safe. To do this, this patch introduces a new gdb_remote_download proc, that works somewhat differently in the one specific case where it matters: for a copy to "host", if no destination was given, and the host is not actually remote, then standard_output_file is used. In parallel mode this guarantees that the resulting file will end up in a parallel-safe location. Tested on x86-64 Fedora 18. * gdb.dwarf2/dw2-basic.exp: Use gdb_remote_download. * gdb.dwarf2/dw2-compressed.exp: Use gdb_remote_download. * gdb.dwarf2/dw2-intercu.exp: Use gdb_remote_download. * gdb.dwarf2/dw2-intermix.exp: Use gdb_remote_download. * gdb.dwarf2/dw2-producer.exp: Use gdb_remote_download. * gdb.dwarf2/mac-fileno.exp: Use gdb_remote_download. * lib/gdb.exp (gdb_remote_download): New proc.

Presently, only the value machinery knows to handle unavailable memory. We need to push the awareness down to the target_xfer layer, making it return a finer grained error indication. We can only return a generic -1 nowadays, which leaves the upper layers with no clue on why the xfer failed. Use target_xfer_partial directly, rather than propagating the error through target_read_memory so as to get a better address to display in the error message. (target_read_memory & friends build on top of target_read (thus the target_xfer machinery), but turn all errors to EIO, an errno value. I think this is a mistake, and we'd better convert all these to return a target_xfer_error too, but that can be done separately. I looked around a bit over memory_error calls, and the need to handle random errno values, other than the EIOs gdb itself hardcodes, probably comes (only) from deprecated_xfer_memory, which uses errno for error indication, but I didn't look exhaustively. We should really get rid of deprecated_xfer_memory and of passing down errno values as error indication in target_read & friends methods). Tested on x86_64 Fedora 17, native and gdbserver.

| | | | | | | | | | | | | | | | | | | | | | This fixes PR python/15816. The bug here is that python-selftest.exp can fail: No symbol "RETURN_MASK_ALL" in current context. RETURN_MASK_ALL is a macro, so if macros do not end up in the debuginfo (very typical) then the test fails. It seemed simplest to me to simply turn the RETURN_MASK_ defines into enum constants. This way they end up in the debuginfo and all is well. PR python/15816: * exceptions.h (return_mask): Now an enum. (RETURN_MASK_QUIT, RETURN_MASK_ERROR, RETURN_MASK_ALL): Now enum constants.

* move gdbarch object from objfile to per-BFDTom Tromey2013-08-2010-21/+41
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This moves the "gdbarch" field from the objfile into the BFD. This field's value is derived from the BFD and is immutable over the lifetime of the BFD. This makes it a reasonable candidate for pushing into the per-BFD object. This is part of the long-term objfile splitting project. In the long run I think this patch will make it simpler to moves types from the objfile to the per-BFD object; but the patch makes sense as a minor cleanup by itself.
