Alan Hayward 3426ae5760 Arm: Allow version strings in the triplet regexp
On Arm, the OS may use the full version string for the arch name when

Tom de Vries 8af58ffe5d [gdb/testsuite] Compile varval twice, once without bad DWARF
When we run gdb.dwarf2/varval.exp with board cc-with-dwz, we run into:
...
gdb compile failed, dwz: varval: Couldn't find DIE referenced by \
  DW_OP_GNU_variable_value
cc-with-tweaks.sh: dwz did not modify varval.
UNTESTED: gdb.dwarf2/varval.exp: failed to prepare
...

The problem is that varval contains some bad DWARF, which has been added
intentionally to test GDB, but that bad DWARF causes dwz to error out, which
has the consequence that the test-case remains untested with cc-with-dwz,
while the test-case contains also correct DWARF that does not occur in any
other test, and which we would really like to test with board cc-with-dwz.

Fix this by compiling varval twice, once without and once with the bad DWARF,
such that we have at least:
...
PASS: gdb.dwarf2/varval.exp: print varval
PASS: gdb.dwarf2/varval.exp: print varval2
PASS: gdb.dwarf2/varval.exp: print constval
PASS: gdb.dwarf2/varval.exp: print mixedval

Tom de Vries 22e217527d [gdb/testsuite] Add back missing debug for index-cache.exp
The proc prepare_for_testing has "debug" as default argument for the options
parameter.

In the commit c596f180a1 "[gdb/testsuite] Compile index-cache.c with
-Wl,--build-id", by setting the options argument we've effectively dropped
"debug".  This causes index-cache.exp to not contain any debug info anymore on
most systems (though not on openSUSE), which causes index-cache.exp FAILs.

Fix this by adding back the missing "debug" option.

Tested on x86_64-linux.

Simon Marchi 4838e44c8f arm-tdep: sort mapping symbols after parsing all minimal symbols
Somebody on IRC reported a while ago that loading a big ARM program in
GDB was very slow.  Their profiling pointed out that a big amount of
time was spent in

    VEC_safe_insert (arm_mapping_symbol_s, *map_p, idx, &new_map_sym);

I was able to verify this as well.

ARM mapping symbols are special ELF symbols named $a, $d and $t
indicating that symbols starting at this address up to the next mapping
symbol (in terms of address) are of type "ARM code", "data" and "Thumb
code", respectively.  GDB records these symbols in vectors (one for each
section) in arm-tdep.c.  These vectors are sorted by symbol address, to
allow for quick lookup.  The current approach is to insert new symbols
at the right position to keep the vectors sorted at all time.  This is
done based on the assumption that mapping symbols come already almost
sorted from the binary, as explains this comment in
arm_record_special_symbol:

  /* Assume that most mapping symbols appear in order of increasing
     value.  If they were randomly distributed, it would be faster to
     always push here and then sort at first use.  */

Well, it turns out this is not the case.  The original reporter
mentioned that mapping symbols in their binaries are not nearly sorted,
and this is not my experience either (at least in the binary used in the
benchmark below).  So if the values don't come nearly sorted, doing
insertions to keep the vectors sorted ends up being of the order of
number_of_mapping_symbols ^ 2.

This patch changes it just like the comment above says, to just append
to the vector in arm_record_special_symbol and sort the vector on first
use.

Benchmark
=========

I have done some benchmarks using an --enable-targets=all GDB, compiled
with -O2, running on x86-64 and parsing file
dce18d22e5c2ecb6a3a57372f4e6ef614130bc.debug from this package:

  https://launchpad.net/ubuntu/+source/firefox/66.0.3+build1-0ubuntu1/+build/16608691/+files/firefox-dbg_66.0.3+build1-0ubuntu1_armhf.deb

This file is the separate debug info for libxul.so (part of firefox) for
ARM.

I have added some traces to measure the execution time of just
elf_symtab_read and ran GDB like this:

  ./gdb --data-directory=data-directory -nx -batch  .../path/to/usr/lib/debug/.build-id/65/dce18d22e5c2ecb6a3a57372f4e6ef614130bc.debug

Since the new code sorts the vectors on first use, it would be difficult
to benchmark it as-is and be fair, since the "before" version does more
work in elf_symtab_read.  So I have actually benchmarked a version of
the patch that did sort all the vectors at the end of elf_symtab_read,
so the sorting would be considered in the measured execution time.

Here's the measured execution time of elf_symtab_read, averaged on 3
runs:

  insert sorted (before): 28.678s
  sort after (after):      1.760s

And here's the total execution time of the command above (just one run).
The time is now mostly spent in reading DWARF.

  insert sorted: 71.12s user 2.71s system 99% cpu 1:14.03 total
  sort after:    46.42s user 2.60s system 99% cpu  49.147 total

I tried for fun on my Raspberry Pi 3, the run time of
elf_symtab_read goes from ~259s to ~9s, reading the same file.

Philippe Waroquiers b65b566cdc Fix alias command not detecting non matching prefix & sometimes asserting.
alias_command does not detect that the prefixes of the alias command and the
aliased command are not matching: it is comparing the alias prefix
with itself, instead of comparing it with the aliased command prefix.

This causes either the alias command to silently do nothing,
or to have GDB asserting:
    (gdb) alias assigne imprime limite-elements = set print elements
    ../../binutils-gdb/gdb/cli/cli-cmds.c:1552: internal-error: void alias_command(const char*, int): Assertion `c_command != NULL && c_command != (struct cmd_list_element *) -1' failed.

Faraz Shahbazker 9b444f9533 MIPS/gas: Fix order of instructions in LI macro expansion
When MTHC1 instruction is paired with MTC1 to write a value to a
64-bit FPR, the MTC1 must be executed first, because the semantic
definition of MTC1 is not aware that software will be using an MTHC1
to complete the operation, and sets the upper half of the 64-bit FPR
to an UNPREDICTABLE value[1].

Fix the order of MTHC1 and MTC1 instructions in LI macro expansion.
Modify the expansions to exploit moves from $zero directly by-passing
the use of $AT, where ever possible.

Tom de Vries 5c2c8c694d [gdb/testsuite] Regenerate dw2-restrict.S
When running gdb.dwarf2/dw2-restrict.exp with board cc-with-dwz, we run into:
...
dwz: dw2-restrict: DW_AT_stmt_list not DW_FORM_sec_offset or DW_FORM_data4
...

The problem is that the DW_AT_stmt_list is encoded using DW_FORM_addr, while
DW_FORM_sec_offset or DW_FORM_data4 would be appropriate.  The test-case uses
a dw2-restrict.S which was generated using clang 2.9, which contained a bug
( https://bugs.llvm.org/show_bug.cgi?id=9995 ) causing this problem.

Fix this by regenerating using clang 5.0.1.

Tom Tromey f936bca26d Remove some TUI static allocations
The TUI statically allocates the "execution_info" for the source and
disassembly windows.  However, there's no deep reason to do this, and
this approach makes it harder to allow multiple such windows.

This patch removes the static data and changes the code to simply
allocate these windows as needed.  This required pushing some code
into the tui_gen_win_info destructor, but that seems like a good idea
anyhow.
