2019-10-26Optimise away eh_frame advance_loc 0Alan Modra3-4/+28
These can be generated when multiple cfi directives are emitted for an instruction and the insn frag is closed off between directives, as happens when listings are enabled. No doubt the advance_loc of zero could be avoided by backtracking over frags in dw2gencfi.c before calling cfi_add_advance_loc, but that seems like more work than cleaning up afterwards as this patch does. Noticed when looking at the testcase in PR25125.

2019-10-25Allow out-of-order reads of CIEsTom Tromey2-75/+25
Currently gdb has an assertion that requires CIEs to be read in the order in which they appear in the debug info: gdb_assert (n < 1 || cie_table->entries[n - 1]->cie_pointer < cie->cie_pointer); This assertion ensures that the table will be sorted, which is important because it is later searched using bsearch. However, a customer provided an executable that causes this assertion to trigger. This executable causes decode_frame_entry_1 to call decode_frame_entry to find the CIE, resulting in an out-of-order read. I don't know a good way to construct a reproducer, but this can happen if the FDE appears before its CIE. See https://sourceware.org/bugzilla/show_bug.cgi?id=16563 This patch fixes the problem by storing CIEs in an unordered map. The CIE table is discarded after the frame section is parsed, so this seemed both simple and straightforward. gdb/ChangeLog 2019-10-25 Tom Tromey <tromey@adacore.com> * dwarf2-frame.c (dwarf2_cie_table): Now a typedef.

2019-10-25PR25125, relaxation chooses wrong branch sizeAlan Modra2-4/+13
The patch I made for PR12049 didn't test for a "negative" branch properly. "if (target < address)" ought to have been "if (target < address + fragP->fr_fix)". Rather than making that change, this patch adds fragP->fr_fix into address earlier. The patch also avoids running into a bad interaction with the m68k md_prepare_relax_scan by returning zero growth immediately, since the adjusted target expression would result in a zero "aim".

2019-10-24gdb/python: Return None from Progspace.block_for_pc on errorAndrew Burgess4-5/+25
The documentation for Progspace.block_for_pc says: Return the innermost gdb.Block containing the given pc value. If the block cannot be found for the pc value specified, the function will return None. However, the implementation actually throws an error for invalid addresses, like this: (gdb) python print gdb.current_progspace ().block_for_pc (1) Traceback (most recent call last): File "<string>", line 1, in <module> RuntimeError: Cannot locate object file for block. Error while executing Python code. (gdb) This has been the behaviour since the command was first added (when the documentation was still as above) in this commit: commit f3e9a8177c41893858fce2bdf339dbe90b3a4ef5 Date: Wed Feb 24 21:18:28 2010 +0000 Since that commit the code in question has moved around, but the important parts are largely unchanged. The function in question is now in py-progspace.c:pspy_block_for_pc. Examining the code shows that the real state is more complex than just the function throws an error instead of returning None, instead the real situation is: 1. If we can't find a compilation unit for the $pc value then we throw an error, but 2. If we can find a compilation unit, but can't find a block within the compilation unit for the $pc then return None. I suspect for most users of the Python API this distinction is irrelevant, and I propose that we standardise on one single failure mechanism. Given the function can currently return None in some cases, and is documented to return None on error, I propose we make that the case for all error paths, which is what this patch does. As the Progspace.block_for_pc method is currently untested, I've added some basic tests including for a call with an invalid $pc. This is potentially an API breaking change, though an undocumented part of the API. Also, users should have been checking and handling a None return value anyway, so my hope is that this shouldn't be too disruptive. gdb/ChangeLog: * python/py-progspace.c (pspy_block_for_pc): Return None for all error paths. gdb/testsuite/ChangeLog: * gdb.python/py-progspace.exp: Add tests for the Progspace.block_for_pc method.

2019-10-23Move readline to the readline/readline subdirectoryTom Tromey152-10492/+15564
readline turns out to be a bit of a stumbling block for the project to move gdbsupport (and then gdbserver) to the top-level. The issue is that readline headers are intended to be included with names like "readline/readline.h". To support this, gdb effectively adds a -I option pointing to the top-level source directory -- but, importantly, this option is not used when the system readline is used. For gdbsupport, a -I option like this would always be needed, but that in turn would break the system readline case. This was PR build/17077, fixed in commit a8a5dbcab8df0b3a9e04745d4fe8d64740acb323. Previously, we had discussed this on the gdb-patches list in terms of removing readline from the tree https://sourceware.org/ml/gdb-patches/2019-09/msg00317.html However, Eli expressed some concerns, and Joel did as well (off-list). Given those concerns, and the fact that a patch-free local readline is relatively new in gdb (it was locally patched for years), I changed my mind and decided to handle this situation by moving the readline sources down a level. That is, upstream readline is now in readline/readline, and the top-level readline directory just contains the minimal configury needed to build that. This fixes the problem because, when gdb unconditionally adds a -I$(top_srcdir), this will not find readline headers. A separate -I will be needed instead, which is exactly what's needed for --with-system-readline. gdb/ChangeLog 2019-10-23 Tom Tromey <tom@tromey.com> * Makefile.in (READLINE_DIR): Update. gdb/doc/ChangeLog 2019-10-23 Tom Tromey <tom@tromey.com> * Makefile.in (READLINE_DIR): Update. readline/ChangeLog 2019-10-23 Tom Tromey <tom@tromey.com> Move old contents to readline/ subdirectory. * aclocal.m4, configure, configure.ac, .gitignore, Makefile.am, Makefile.in, README: New files.

2019-10-23infcall: refactor 'call_function_by_hand_dummy'Tankut Baris Aktemur2-25/+45
Extract out the code region that reserves stack space to a separate function. Fix the comment of 'call_function_by_hand_dummy' to remove reference to the NARGS argument that was removed in commit (e71585ffe2e "Use gdb:array_view in call_function_by_hand & friends"). gdb/ChangeLog: 2019-10-23 Tankut Baris Aktemur <tankut.baris.aktemur@intel.com> * infcall.c (call_function_by_hand_dummy): Fix the function comment.

2019-10-23infcall: move assertions in 'call_function_by_hand_dummy' to an earlier spotTankut Baris Aktemur2-20/+25
This is a refactoring that performs type assertions on the callee function at the beginning of 'call_function_by_hand_dummy' rather than at a later point so that - the checks are grouped together at the beginning of the function for improved readability, and - we don't have to align and push things on the stack only to find out later that the function call is illegal. gdb/ChangeLog: 2019-10-23 Tankut Baris Aktemur <tankut.baris.aktemur@intel.com> * infcall.c (call_function_by_hand_dummy): Refactor.

2019-10-23Check for sigprocmask in common.m4Tom Tromey7-5/+21
I noticed that gdbsupport uses HAVE_SIGPROCMASK, but common.m4 does not check for it. This means that gdbserver may not compile some gdbsupport code properly. This patch fixes this error. gdb/ChangeLog 2019-10-23 Tom Tromey <tom@tromey.com> * configure: Rebuild. * configure.ac: Don't check for sigprocmask. * gdbsupport/common.m4 (GDB_AC_COMMON): Check for sigprocmask. gdb/gdbserver/ChangeLog 2019-10-23 Tom Tromey <tom@tromey.com> * configure, config.in: Rebuild.

Pedro pointed out that sinclude does not error if a file is missing.
