2020-08-25arc: Add GNU/Linux support for ARCAnton Kolesov6-2/+298
ARC Linux targets differences from baremetal: - No support for hardware single instruction stepping. - Different access rules to registers. - Use of another instruction for breakpoints. v2: Changes after Tom's remarks [1] arc-linux-tdep.c - Use true/false instead of TRUE/FALSE. - arc_linux_sw_breakpoint_from_kind (): Break long lines into two. - arc_linux_sw_breakpoint_from_kind (): Remove starting blank line. - Use explicit number evaluation, e.g: if (a & b) -> if ((a & b) != 0) arc-tdep.c - Use explicit number evaluation, e.g: if (a & b) -> if ((a & b) != 0) gdb/configure.tgt - arc*-*-linux*): Remove "build_gdbserver=yes". v3: Changes after Simon's remarks [2] arc-linux-tdep.c - Use "return trap_size" instead of cryptic "return 2". - Removed unnecessary curly braces. - Removed "void" from "_initialize_arc_linux_tdep (void)". v5: Changes after Simon's remarks [3] - Remove unnecessary empty lines. - Replace "breakpoint uses" with "breakpoints use" in a comment. - "return condition;" i.s.o.

2020-08-25arc: Add hardware loop detectionShahab Vahedi5-6/+56
For ARC there are registers that are not part of a required set in XML target descriptions by default, but are almost always present on ARC targets and are universally exposed by the ptrace interface. Hardware loop registers being one of them. LP_START and LP_END auxiliary registers are hardware loop start and end. Formally, they are optional, but it is hard to find an ARC configuration that doesn't have them. They are always present in processors that can run GNU/Linux. GDB needs to know about those registers to implement proper software single stepping, since they affect what instruction will be next. This commit adds the code to check for the existance of "lp_start" and "lp_end" in XML target descriptions. If they exist, then the function reports that the target supports hardware loops. gdb/ChangeLog: * arc-tdep.c (arc_check_for_hardware_loop): New. * arc-tdep.h (gdbarch_tdep): New field has_hw_loops. gdb/doc/ChangeLog: * gdb.texinfo (Synopsys ARC): Document LP_START, LP_END and BTA.
2020-08-25arc: Add inclusion of "gdbarch.h" in "arc-tdep.h"Shahab Vahedi2-0/+5

2020-08-25arc: Add ARCv2 XML target along with refactoringShahab Vahedi19-349/+691
A few changes have been made to make the register support simpler, more flexible and extendible. The trigger for most of these changes are the remarks [1] made earlier for v2 of this patch. The noticeable improvements are: - The arc XML target features are placed under gdb/features/arc - There are two cores (based on ISA) and one auxiliary feature: v1-core: ARC600, ARC601, ARC700 v2-core: ARC EM, ARC HS aux: common in both - The XML target features represent a minimalistic sane set of registers irrespective of application (baremetal or linux). - A concept of "feature" class has been introduced in the code. The "feature" object is constructed from BFD and GDBARCH data. It contains necessary information (ISA and register size) to determine which XML target feature to use. - A new structure (ARC_REGISTER_FEATURE) is added that allows providing index, names, and the necessity of registers. This simplifies the sanity checks and future extendibility. - Documnetation has been updated to reflect ARC features better. - Although the feature names has changed, there still exists backward compatibility with older names through find_obsolete_[core,aux]_names() functions. The last two points were inspired from RiscV port. [1] https://sourceware.org/pipermail/gdb-patches/2020-May/168511.html gdb/ChangeLog: * arch/arc.h (arc_gdbarch_features): New class to stir the selection of target XML.

When building with gcc with -gdwarf-5 ld tests (including ld-elf/dwarf.exp) fail because they try to read the .debug_ranges section. But DWARF5 introduces a new .debug_rnglists section that encodes the address ranges more efficiently. Implement reading the debug_rnglists in bfd/dwarf2.c.

2020-08-25gdb/modula-2: parsing of multi-subscript arraysGaius Mulley5-7/+96
Fix bug PR m2/26372, GDB's inability to parse multi-dimensional modula-2 arrays. We previously had two rules for handling the parsing of array sub-scripts. I have reproduced them here with the actual handler blocks removed to make the bug clearer: exp : exp '[' non_empty_arglist ']' ; exp : exp '[' exp ']' ; non_empty_arglist : exp ; non_empty_arglist : non_empty_arglist ',' exp ; This is ambiguous as the pattern "exp '[' exp" could match either of the 'exp' rules. Currently it just so happens that the parser picks the second 'exp' rule which means we can only handle a single array index. As the handler code for the first 'exp' pattern will correctly handle and number of array indexes then lets just remove the second pattern. gdb/ChangeLog: PR m2/26372 * m2-exp.y (exp): Improve comment for non_empty_arglist case, add an assert.

2020-08-24gdb/testsuite: make runto always emit a FAIL on internal errorSimon Marchi2-3/+7
I noticed that when a test uses `runto_main` and a GDB internal error happens while running to main, no error or fail is emitted. This is because `runto_main` uses the `no-message` option of `runto`. As a result, if a test fails to run to main and exits, no sign that something went wrong is emitted. For example, add this always-false assertion to compute_frame_id: --- a/gdb/frame.c +++ b/gdb/frame.c @@ -545,6 +545,7 @@ static void compute_frame_id (struct frame_info *fi) { gdb_assert (!fi->this_id.p); + gdb_assert (false); if (frame_debug) fprintf_unfiltered (gdb_stdlog, "{ compute_frame_id (fi=%d) ", ... and run gdb.dwarf2/dw2-align.exp. No fail or sign that something went wrong is shown. It just appears as if the test gets skipped. A developer introducing such a regression in this test today would likely notice it, because we are used to diff-ing test results. So we would see some PASSes dispappear for no good reason and look into it. But I find it worrysome for two reasons: 1. Scripts that analyze regressions (such as the one on the buildbot) may only look for new FAILs or new ERRORs. It would probably miss this. 2. Imagine that we one day have a testsuite that runs cleanly (some people might already run subsets of the testsuite and expect it to all pass), we would just run the testsuite and check that there are no fails. It would be easy to miss something like this. In case of internal error, I suggest making `runto` emit a FAIL even if `no-message` was passed. This is different from other failure modes that might be expected (whchi rightfully cause the test to simply be skipped). An internal error is always bad, so if it happens it should noisily fail. gdb/testsuite/ChangeLog: * lib/gdb.exp (runto): Always emit fail on internal error.

Introduce this macro to print debug statements in the infrun.c file, same idea as what was done in 9327494e0eeb ("gdb: add linux_nat_debug_printf macro"). Although in this case, there are places outside infrun.c that print debug statements if debug_infrun is set. So the macro has to be declared in the header file, so that it can be used in these other files. Note one special case. In stop_all_threads, I've used an explicit if (debug_infrun) infrun_debug_printf_1 ("stop_all_threads", "done"); for the message in the SCOPE_EXIT. Otherwise, the message appears like this: [infrun] operator(): done Until we find a better solution for extracting a meaningful function name for lambda functions, I think it's fine to handle these special cases manually, they are quite rare.

2020-08-24tic54x fixesAlan Modra5-29/+33
A number of the tic54x tests were failing, and I thought it worth investigating since the target makes use of a lot of hash tables, and we've just changed gas hash tables. It turns out none of the gas failures were due to hashing. * config/tc-tic54x.c (stag_add_field_symbols): Don't free "name" in case where it isn't copied. * config/tc-tic54x.h (LOCAL_LABELS_FB): Undef. * testsuite/gas/tic54x/field.d: Dump section contents and symbols rather than disassembling. * testsuite/gas/tic54x/set.d: Adjust for newer disassembly.
2020-08-24PowerPC TPREL_HA/LO optimisationAlan Modra17-200/+436
ppc64 ld optimises sequences like the following addis 3,13,wot@tprel@ha lwz 3,wot@tprel@l(3) to nop lwz 3,wot@tprel(13) when "wot" is located near enough to the thread pointer. However, the ABI doesn't require that R_PPC64_TPREL16_HA always be on an addis rt,13,imm instruction, and while ld checked for that on the high-part instruction it didn't disable the optimisation on the low-part instruction. This patch fixes that problem, disabling the tprel optimisation globally if high-part instructions don't pass sanity checks. The optimisation is also enabled for ppc32, where before ld.bfd had the code in the wrong place and ld.gold had it in a block only enabled for ppc64. bfd/ * elf32-ppc.c (ppc_elf_check_relocs): Set has_tls_reloc for high part tprel16 relocs.
