After seeing Simon's patch to change arm_per_objfile to use new and
delete, I realized it is now simple to change arm_objfile_data_key to
use the type-safe registry.

4 bits (0xF) could be passed to the SMC (Secure Monitor Call) instruction.
For example, this code is invalid:
smc #0x6951
The code would previously check for and encode for up to 16 bit immediate values, however
this immediate should instead be only a 4 bit value
(as documented herehttps://static.docs.arm.com/ddi0406/c/DDI0406C_C_arm_architecture_reference_manual.pdf ).
Fixed this by adding range checks in the relevant areas and also removing code that would
encode more than the first 4 bits of the immediate (code that is now redundant, as any immediate operand
larger than 0xF would error now anyway).

These files were mistakenly left out of commit c1dc7af521.

There's no point doing a separate decode of the VEX.L bit - both decoded
forms are identical.
|
|
These encodings aren't valid in real and VM86 modes, but they are very
well usable in 16-bit protected mode.
A few adjustments in the disassembler tables are needed where Ev or Gv
were wrongly used. Additionally an adjustment is needed to avoid
printing "addr32" when that's already recognizable by the use of %eiz.
Furthermore the Iq operand template was wrong for XOP:0Ah encoding
insns: They're having a uniform 32-bit immediate. Drop Iq and introduce
Id instead.
Clone a few existing test cases to exercise assembler and disassembler.

Noticed by a customer while looking at a tangentially related problem. The
gas testsuite for xstormy16 has two scripts that have a typo on the first
line, they are missing the !. They also use shell syntax that doesn't work
on a system where /bin/sh is dash. So I fixed the typo, changed the shell
to bash, and made them executable, so that they now work when run directly
even if /bin/sh is dash.

Without the ELF header to set info->endian, it ends up as BFD_UNKNOWN_ENDIAN
which gets printed as big-endian. But RISC-V instructions are always little
endian, so we can set endian_code correctly, and then set display_endian from
that. This is similar to how the aarch64 support works, but without the
support for constant pools, as we don't have that on RISC-V.

On Arm, the OS may use the full version string for the arch name when
installing the compiler, for example armv7hl-redhat-linux-gnueabi-gcc.

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

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.

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.

* arm-tdep.c (struct arm_per_objfile) <section_maps_sorted>: New
field.

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.

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.

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.

There is only a single caller of tui_alloc_win_info, and we're going
to add more "new" cases to that caller, so remove tui_alloc_win_info
and inline it into init_and_make_win.

* tui/tui-data.h (tui_alloc_win_info): Don't declare.

This changes tui_set_win_focus_to so that it no longer checks the
window type. Instead, now tui_unhighlight_win also checks whether the
window can be highlighted.

This introduces a new tui_win_info::update_tab_width method, and
changes the TUI to call it. This fixes another spot that was checking
the window type.

This adds a new enum to the TUI, replacing two #define constants,
providing better type safety.

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.
gdb/ChangeLog
2019-06-25 Tom Tromey <tom@tromey.com>
* tui/tui-layout.c (make_source_or_disasm_window): Always use
init_and_make_win for EXEC_INFO_WIN.

longer inline.
(struct tui_win_info) <~tui_win_info>: Inline.

This introduces the tui_gen_win_info::reset method and changes various
places to use it. This led to the realization that the can_highlight
member only needs to be set during construction, so this patch makes
that change as well. Finally, init_and_make_win is drastically
simplified.
gdb/ChangeLog
2019-06-25 Tom Tromey <tom@tromey.com>
* tui/tui-layout.c (make_command_window): Don't set
can_highlight.
(show_source_disasm_command): Call the reset method.

(tui_gen_win_info::reset): Rename from init_gen_win_info
(init_and_make_win): Simplify. Return tui_gen_win_info.
(show_source_or_disasm_and_command): Call the reset method.
* tui/tui-data.h (struct tui_gen_win_info) <reset>: New method.
(struct tui_cmd_window): Set can_highlight.

This moves the make_visible method from tui_win_info to its base
class, tui_gen_win_info. This allows the removal of another window

The tui_scroll_direction enum is not really needed, because it's
simple to adapt the various scrolling methods to use the sign of their
argument as the direction in which to scroll.

Several more TUI functions should only be called with a source or
disassembly window. This patch changes these functions so that this
can be caught at compile time.
