PR26437, PR26438 UBSAN: tc-cr16.c left shifts and overflows
...
Always use unsigned constants in expressions generating masks. The
following trys mightily to avoid UB (but hits it anyway with bits=32
and 0x7fffffff << 1), and worse, for 32-bit int, 64-bit long, bits=32
doesn't generate 0xffffffff.
max = ((((1 << (bits - 1)) - 1) << 1) | 1);
results in -1, or max = 0xffffffffffffffff.
This patch fixes that problem, a possible shift exponent of -1U,
removes some dead code, and makes general tidies.

Inserting with replacement is wrong for some gas hash table uses.
This patch implements an htab_insert that conditionally replaces, and
similarly for str_hash_insert. str_hash_insert with replace=0 is
roughly equivalent to the older hash_insert, and str_hash_insert with
replace=1 to the older hash_jam, but return values are different. I
found it useful to know whether the slot was occupied prior to
inserting/replacing. I've also reinstated the fatal errors on messing
up opcode tables with duplicates.

gas: Fix internal error in S_SET_SEGMENT
...
This patch fixes an internal error in GAS when defining a section using
a symbol that has already been named but not defined. For a minimal
reproducer, try the following input:
a=b
.sect a
The problem is that obj_elf_change_section() happily reuses the symbol
"a" created by equals() without clearing the sy_value field: prior to
this patch, it just set bsym. This caused a problem when attempting to
resolve the section symbol, since resolve_symbol_value() ended up
resolving the symbol as if it were the original symbol created by
equals(), which ends up leaving the section symbol in the undefined
section instead of in section a, hence the call to abort() in
S_SET_SEGMENT().
gas/ChangeLog:
* config/obj-elf.c (obj_elf_change_section): When repurposing an
existing symbol, ensure that we set sy_value as per other (fresh)
section symbols.

x86: handle SVR4 escaped binary operators
...
PR gas/4572
When / is a comment character, its use as binary "divide" operator needs
escaping by a backslash. Besides the scrubber needing to support this
(addressed in an earlier change), there are also a few provisions needed
in target specific operator handling.
As the spec calls for % and * to also be escaped because of being
"overloaded", also recognize these, despite the overloading there not
really preventing their use as operators in most (%) or all (*) cases,
given the way how the rest of the assembler works.
To bring source and testsuite in line, also drop the TE_I386AIX part of
the respective conditional, as i?86-*-aix* support had been removed a
while ago.

x86: honor absolute section when emitting code
...
Various provisions exist for insns to be placed in the absolute section,
yet actually trying to do so didn't work. While data emission (of non-
zero values) is not allowed by generic code, I think this functionality
is useful for the programmer to be able to determine the size of insns.
Therefore, rather than turning the silnet failure into a verbose one,
make things mostly work; the one class of insns not supported (yet) are
branches (JMP and Jcc) with dynamically determined displacement widths.
In this one case, an error now gets reported instead of silently
ignoring the code.
Also avoid recording ISA / feature usage for insns emitted to the
absolute section.
