Hi,
Ref.: https://bugzilla.redhat.com/show_bug.cgi?id=1708192https://bugzilla.redhat.com/show_bug.cgi?id=1708786
During the Fedora RPM build process, gdb-add-index is invoked to
extract the DWARF index from the binary, and GDB will segfault because
dwarf2read.c:parse_definition_macro's 'body' variable is NULL.
The underlying problem is that Fedora's rpm-build's "debugedit"
program will silently corrupt .debug_macro strings when a binary is
compiled with -g3. This is being taken care of by Mark Wielaard,
here:
https://bugzilla.redhat.com/show_bug.cgi?id=1708786
However, I still feel it's important to make GDB more resilient
against invalid DWARF input, so I'm proposing this rather simple patch
to catch the situation when "body == NULL" (i.e., it's probably been
corrupted) and issue a complaint. This is not a real fix to the
problem, of course, but at least GDB is able to finish without
segfaulting.
OK for master?

Ref.: https://bugzilla.redhat.com/show_bug.cgi?id=1708192
* dwarf2read.c (dwarf_decode_macro_bytes): Check whether 'body' is
NULL, and complain if that's the case.
Fixes a failure seen with MALLOC_PERTURB_=1.
* elf32-arm.c (elf32_arm_write_section): Don't leave
error case of STM32L4XX_ERRATUM_BRANCH_TO_VENEER with
unitialised section contents.
This adds another test for file numbers given in .file directives,
checking that the value can be represented as an unsigned int and that
a memory allocation expression doesn't overflow. I removed a test
added recently since an earlier test (num < 1) already covers the
(num < 0) case.
* dwarf2dbg.c: Whitespace fixes.
(get_filenum): Don't strdup "file". Adjust error message.
(dwarf2_directive_filename): Use an unsigned type for "num".
Catch truncation of file number and overflow of get_filenum
XRESIZEVEC multiplication. Delete dead code.

tic54x-coff +FAIL: c54x subsym assignment/use

* config/tc-tic54x.c (tic54x_start_line_hook): Do skip end of line
chars in setting endp.
Previously, the stack unwinder searched through consecutive bytes for values
which it thought might be the start of a stack mutating operation.
This was error prone, because such bytes could also be the operands of other
instructions. This change uses the opcodes api to interpret the code in each
frame.
gdb/ChangeLog:
* s12z-tdep.c (push_pull_get_stack_adjustment): New function.
(advance, posn, abstract_read_memory): New functions.
[struct mem_read_abstraction]: New struct.
(s12z_frame_cache): Use opcodes API to interpret stack frame code.
coerce_unspec_val_to_type does:
set_value_address (result, value_address (val));
However, this is only valid for lval_memory. This patch changes this
code to only set the address for lval_memory values.
This seems like an ordinary oversight in coerce_unspec_val_to_type,
and a test case would be difficult to write, so I'm submitting it
without a test case.
Tested on x86-64 Fedora 29; plus using an Ada program that exhibits
the bug (but which cannot be shared).

* ada-lang.c (coerce_unspec_val_to_type): Only set address when
value is not lval_memory.
The "automatic symbol index cache" entry in the docs is missing entries in the
concept and command indices. Add them.

A base address selection entry in a location list consist of two (constant or
relocated) address offsets. The two offsets are the same size as an address
on the target machine.
The test-case gdb.dwarf2/dw2-skip-prologue.S encodes a base address selection
entry using .4byte, which is incorrect for 8-byte pointer size. [ Which
triggers an assert in dwz, see PR dwz/24172. ]
Fix this by using PTRBYTE instead.
Tested on x86_64-linux.
