PR25081, Discrepancy between VMA and LMA after ALIGN
The testcase in the PR has two empty output sections, .sec1 with an
ALIGN and symbol assignment, and .sec2 just with an empty input
section. The symbol assignment results in .sec1 being kept, but
because it is empty this section doesn't take space from the memory
region as you might expect from the ALIGN. Instead the next section
.sec2, has vma/lma as if .sec1 wasn't present. However, .sec2 is
discarded and os->ignored set, which unfortunately meant that dot
wasn't set from .sec2 vma. That in turn results in .sec2 lma being
set incorrectly. That vma/lma difference is then propagated to
.sec3 where it is seen as an overlap.

[PR ld/22263][PR ld/25056] arm: Avoid dynamic TLS relocs in PIE
Dynamic relocs are only needed in an executable for TLS symbols if
those are defined in an external module and even then TLS access
can be relaxed to use IE model instead of GD.
Several bfd_link_pic checks are turned into bfd_link_dll checks
to fix TLS handling in PIE, for the same fix some other targets
used !bfd_link_executable checks, but that includes relocatable
objects so dll seems safer (in most cases either should work, since
dynamic relocations are not applied in relocatable objects).

PowerPC PIC vs. DLL TLS issues
1) GOT entries generated for any of the GOT TLS relocations don't need
dynamic relocations for locally defined symbols in PIEs. In the case
of a tls_index doubleword, the dtpmod entry is known to be 1, and the
dtprel entry is also known at link time and relative. Similarly,
dtprel and tprel words are known at link time and relative. (GOT
entries for other than TLS symbols are not relative and thus need
dynamic relocations in PIEs.)
2) Local dynamic TLS code is really only meant for accesses local to
the current binary. There was a cheapskate test for this before using
the common tlsld_got slot, but the test wasn't exactly correct and
might confuse anyone looking at the code. The proper test,
SYMBOL_REFERENCES_LOCAL isn't so expensive that it should be avoided.
3) The same cheap test for local syms when optimising TLS sequences
should be SYMBOL_REFERENCES_LOCAL too.

PR24981, Hit assertion failure in ld/ldlang.c:7504
This fixes a problem with commit
128bf1fe608, a patch I made
2019-08-06. Apparently it is possible to trigger the assertion I
added during an LTO bootstrap, something I haven't reproduced.
However, I did find a case triggered by an odd linker script feature
that allows a file to be loaded from the script without specifying
that file on the command line. Regarding input sections:
"When you use a file name which is not an archive:file specifier
and does not contain any wild card characters, the linker will
first see if you also specified the file name on the linker command
line or in an INPUT command. If you did not, the linker will
attempt to open the file as an input file, as though it appeared on
the command line."
So putting
.foo : { foo.a(*) }
into a script supposedly extracts foo.a into .foo. Except it doesn't,
since this feature is meant for object files only. Well anyway,
assuming --whole-archive was given on the command line, foo.a contains
a -flto object and no other objects involved were -flto then we'll hit
the assert due to files added like foo.a here *not* having their input
statement put on the general statement list. Why these are not put on
the statement list isn't obvious but it has been that way since commit
193c5f93a17 in 1994.

[gdb/testsuite] Restore breakpoint command in ui-redirect.exp
In gdb.base/ui-redirect.exp, the "save breakpoint" command is used to write
the current breakpoints to a file, but the actual output is not verified.
Consequently, the test has regressed in that the "print 1" command associated
with a breakpoint on main is removed by a subsequent runto_main, which first
deletes all breakpoints:
...
(gdb) break main
Breakpoint 1 at 0x4004d7: file start.c, line 34.
(gdb) commands
Type commands for breakpoint(s) 1, one per line.
End with a line saying just "end".

> PASS: gdb.base/ui-redirect.exp: print 1
end
(gdb) PASS: gdb.base/ui-redirect.exp: end
delete breakpoints
Delete all breakpoints? (y or n) y
...
and consequently the "save breakpoint" output is missing the breakpoint
command for main:
...
break main
- commands
- print 1
- end
break foo
break bar
...
Fix this by replacing "gdb_breakpoint main" with runto_main, and verifying the
"save breakpoints" output.

PowerPC warning on symbol+offset@got

Alan Modra [Thu, 5 Sep 2019 00:36:42 +0000 (10:06 +0930)]
PowerPC64 GOT_PCREL relocs
PC-relative relocs typically use the addend in adjusting what they are
relative to. For example:
bcl 20,31,1f
1: mflr 12
addi 12,12,xxx-1b
generates "R_PPC64_REL16 xxx+0x4" for the addi (when little-endian).
The addend reflects the fact that you want the offset relative to the
previous insn not the current one in this case.
So the question is, will we ever want to do something like that for an
instruction using R_PPC64_GOT_PCREL34? I thought so at the time I
first implemented support in ld but at the time I think the hardware
was possibly going to support pcrel+offset+reg addressing. In which
case you might want something like:
load_big_offset_into_r2
pld 3,sym-big_offset@got@pcrel(2)
which would be a way of supporting more than 8G offsets from code to
the GOT. We could do the same with
load_big_offset_into_r2
pla 9,sym-big_offset@got@pcrel
ldx 3,9,2
However, this is really a poor version of TOC-pointer relative code.
So let's go with an addend on R_PPC64_GOT_PCREL34 meaning that
sym+addend should be put in a GOT entry, and the relocation calculate
the pc-relative offset to that GOT entry.
Note that this is an extension to the ABI, which says (by the
expression given for GOT relocs) that non-zero addends on GOT and PLT
relocs are ignored. This is true for all GOT/PLT relocs, not just the
pcrel ones.
* elf64-ppc.c (ppc64_elf_check_relocs): Interpret an addend in
GOT_PCREL and PLT_PCREL relocs as affecting the value stored

Handle biased types
In Ada, the programmer can request that a range type with a non-zero
base be stored in the minimal number of bits required for the range.
This is done by biasing the values; so, for example, a range of -7..-4
may be stored as two bits with a bias of -7.
This patch implements this for gdb. It is done by adding a bias to
struct range_bounds and then adjusting a few spots to handle this.
The test case is written to use -fgnat-encodings=minimal, but a future
compiler patch will change the compiler to emit DW_AT_GNU_bias with
-fgnat-encodings=gdb. It seemed good to get the gdb patch in first.

Remove "\nError: " suffix from nat/fork-inferior.c:trace_start_error warning message
Rationale: https://sourceware.org/ml/gdb-patches/2019-08/msg00651.html
This very simple patch removes the "\nError: " suffix from the warning
message printed by nat/fork-inferior.c:trace_start_error. This proved
to just pollute the screen, causing things like:
Starting program: /usr/bin/true
warning: Could not trace the inferior process.
Error:
warning: ptrace: Permission denied
This "Error: " string is not useful at all, and can confuse things,
therefore let's just remove it and simplify the resulting messages:
Starting program: /usr/bin/true
warning: Could not trace the inferior process.
warning: ptrace: Permission denied

* nat/fork-inferior.c (trace_start_error): Remove "\nError: "
suffix from warning message.

Remove tui_win_info::refresh_all
The TUI has two duplicate "re-render this window" methods, "rerender"
and "refresh_all". They differ only slightly in semantics, so I
wanted to see if they could be unified.
After looking into this, I decided that refresh_all was not needed.
There are 4 calls to tui_refresh_all_win (the only caller of this
method):
1. tui_enable. This sets the layout, which renders the windows.
2. tui_cont_sig. Here, I think it's sufficient to simply redraw the
current window contents from the curses backing store, because gdb
state didn't change while it was suspended
3. tui_dispatch_ctrl_char. This is the C-l handler, and here it's
explicitly enough to just refresh the screen (as above).
4. tui_refresh_all_command. This is the command equivalent of C-l.
So, this patch removes this method entirely and simplifies
tui_refresh_all_win.

Don't call wrefresh from tui_cont_sig
tui_cont_sig does not need to call wrefresh, because this is already
done by tui_refresh_all_win.

Minor rearrangement of tui-stack.c
This move _initialize_tui_stack to the end of tui-stack.c, per the gdb
style; and then removes two unnecessary forward declarations.
