[TargetLowering][RISCV] Disable the special illegal type expansion of ISD::AVGFLOORU on RV32 (#181073)
RISC-V doesn't have a carry flag which makes the UADDO expansion
expensive to emulate.
I've disabled the code by checking if UADDO is not supported for the
type that will be legalized too. Unfortunatley, we have custom lowering
of UADDO on RV64 so this doesn't disable this code there.

[X86][AVX10] Change MINMAX sign control to select the sign of compare result (#183452)
The imm8[3:2] controls the sign bit behavior. 0b01 represents to select
the sign of compare result, while 0b00 select the sign of Src1.
[RISCV] Add processor definitions for XuanTie C910V2 and C920V2 (#174056)
XuanTie C910V2 and C920V2 are 64-bit superscalar out-of-order CPUs:
https://www.xrvm.com/community/download?id=4530178488929423360
C910V2 is a C920V2 version without vector, zvfbfmin, zvfbfwma, zvfh and
xtheadvdot extensions.
Scheduling model will be added in a further PR.
[clang][Sema] Guard polymorphic check in TransformCXXTypeidExpr for incomplete record types (#180442)

Refinements to the output when the EXTERROR_VERBOSE environment is set
When kernel external errors are available they are included in the
err(3) library function messages. In addition to the extended error
itself, the kernel also tracks the kernel file and line number at
which the error was generated. This additional information is not
included in the err(3) messages unless the EXTERROR_VERBOSE environment
variable is present. Currently, when EXTERROR_VERBOSE is present,
all the internal extended error information associated with the
error is printed most of which is redundant with the formatted error
message printed by err(3). This change will add only the kernel
file and line number to the err(3) message when EXTERROR_VERBOSE
is present and set to "brief".
Sample output with bad protection bits to mmap:
guest_16 % ./Example bigfile
Example: mmap bigfile: Invalid argument (unknown PROT bits 0x8)

lpd: Improve robustness
* Check for integer overflow when receiving file sizes.
* Check for buffer overflow when receiving file names, and fully
validate the names.
* Check for integer overflow when checking for available disk space.
* Check for I/O errors when sending status codes.
* Enforce one job per connection and one control file per job (see
code comments for additional details).
* Simplify readfile(), avoiding constructs vulnerable to integer
overflow.
* Don't delete files we didn't create.

[SystemZ] Emit external aliases for indirect function descriptors in the ADA section
This is the last of the three patches aimed to support indirect symbol handling for
the SystemZ backend.
An external alias is emitted for indirect function descriptors within the ADA
section, rather than a temporary alias, while also setting all of the appropriate
symbol attributes that are needed for the HLASM streamer to emit the correct XATTR
and ALIAS instructions for the indirect symbols.
Moreover, this patch updates the `CodeGen/SystemZ/zos-ada-relocations.ll` test
as the ADA section is currently the only user of indirect symbols on z/OS.
[SystemZ] Emit external aliases required for indirect symbol handling support
This is the second of three patches aimed to support indirect symbol handling for
the SystemZ backend. An external name is added for both MC sections and symbols
and makes the relevant printers and writers utilize the external name when present.
Furthermore, the ALIAS HLASM instruction is emitted after every XATTR instruction.
[SystemZ] Add indirect reference bit XATTR REFERENCE(INDIRECT) for indirect symbol handling support
This is the first of three patches aimed to support indirect symbol handling for
the SystemZ backend. This PR introduces a `GOFF:ERAttr` to represent indirect
references, handles indirect symbols within `setSymbolAttribute()` by setting
the indirect reference bit, and also updates the HLASM streamer to emit
`XATTR REFERENCE(INDIRECT)` and various other combinations.
[BOLT][merge-fdata] Skip truncated lines in raw profile data (#183187)
Raw profile data file may contain lines truncated due to unexpected
app exit. This change is to have merge_fdata check number of fields

is not expected.
