This implements the loading of the leap-seconds.list file and store its
contents in the tzdb struct.
This adds the required `leap_seconds` member.
The class leap_seconds is fully implemented including its non-member
functions.
Implements parts of:
- P0355 Extending <chrono> to Calendars and Time Zones
- P1614 The Mothership has Landed
Implements:
- P1981 Rename leap to leap_second
- LWG3359 <chrono> leap second support should allow for negative leap
seconds
- LWG3383 §[time.zone.leap.nonmembers] sys_seconds should be replaced
with seconds

Closes #87254.

Revise the printing functionality of TimingManager to accommodate
various output formats. At present, TimingManager is limited to
outputting data solely in plain text format. To overcome this
limitation, I have introduced an abstract class that serves as the
foundation for printing. This approach allows users to implement
additional output formats by extending this abstract class. As part of
this update, I have integrated support for JSON as a new output format,
enhancing the ease of parsing for subsequent processing scripts.

This is a preparation to use Clang HEAD in the CI.

shuffle(cast(x),cast(y)) -> cast(shuffle(x,y))

(#87382)
…ng VOPC.
Fixes support on GFX1150 and GFX12 where src1 of e64_dpp instructions
should allow sgpr and imm operands.
PR #67461 added support for this with int operands, but it was missing a
piece for float.
Changing VOPC e64_dpp will be in a different patch because there is a
bug preventing that change.

Size was clearly not correct here. This call has been here since
the initial reformat of all of lldb so it has likely always been
incorrect.
(although registers don't typically have an endian, they are
just values, in the remote protocol register data is in target
endian)
This might have been a problem for Neon registers on big endian
AArch64, but only if the debug server describes them as integers.
lldb-server does not, they've always been vectors which doesn't
take this code path.
Not adding a test because the way I've mocked up a big endian
target in the past is using s390x as the architecture. This
apparently has some form of vector extension that may be 128 bit
but lldb doesn't support it.

This copies the change made in google benchmark
(https://github.com/google/benchmark/commit/70916cbf71f50b9e1e6f13559e10d6dbb92beb32)
to remove COMPILER_IBMXL for z/OS.

- Remove trailing type from value attributes as emitc.opaque attributes
are untyped.
- Replace invalid trailing * in opaque type by wrapping it into an
!emitc.ptr.

This is a follow-up of PR:
https://github.com/llvm/llvm-project/pull/79038
|

This patch implements the implicit truncation and implicit sign change
checks for bitfields using UBSan. E.g.,
`-fsanitize=implicit-bitfield-truncation` and
`-fsanitize=implicit-bitfield-sign-change`.

This commit extends the data layout subsystem with accessors for the
endianness. The implementation follows the structure implemented for
alloca, global, and program memory spaces.

This PR is to address `TODO(loc, "procedure pointer component default
initialization");`.
It handles default init for procedure pointer components in a derived
type that is 32 bytes or larger (Default init for smaller size type has
already been handled).
```
interface
subroutine sub()
end
end interface
type dt
real :: r1 = 5.0
procedure(real), pointer, nopass :: pp1 => null()
real, pointer :: rp1 => null()
procedure(), pointer, nopass :: pp2 => sub
end type
type(dt) :: dd1
end
```

Based off #85592 - our truncation -> PACKSS/PACKUS folds should be able to use the nsw/nuw flags to recognise when we don't need to mask/sext_inreg prior to the PACKSS/PACKUS nodes.

This is an exact upstreaming of the downstream diff. Minor
simplifications can be made in the future but upstreaming as-is will
make it easier for us to deal with downstream merge conflicts.
Partially fixes #83805

Hi all,
This patch is a follow-up of #79101. It migrates logic from
`visitVSELECT` to `visitVP_SELECT` to simplify `vp.select`. With this
patch we can do the following combinations:
```
vp.select undef, T, F --> T (if T is a constant), F otherwise
vp.select <condition>, undef, F --> F
vp.select <condition>, T, undef --> T
vp.select false, T, F --> F
vp.select <condition>, T, T --> T
```
I'm a total newbie to llvm and I'm sure there's room for improvements in
this patch. Please let me know if you have any advice. Thank you in
advance!

This is an extension to 07151f0241d3f893cb36eb2dbc395d4098f74a87 which handled SandyBridge so we at least model the regression identified in #14640
Confirmed by Agner + uops.info/uica (SkylakeServer also had an incorrect use of Port015 instead of just Port01)
I raised #86669 as a proposal for a 'x86 unfold' pass that can unfold these (if we have the free registers) driven by the scheduler model.

It's a common pattern that we have a machine type, but we don't care
which ARM64* platform we're dealing with. We already have
isAnyArm64 for that, but it does not fit cases where we use a switch
statement. With this helper, it's easy to simplify such cases by using
Triple::ArchType instead of machine type.

appending linkage (#69613)
This is a proper fix for https://github.com/llvm/llvm-project/issues/40308
|
|
Empty structs are ignored for parameter passing purposes, but va_arg was
incrementing the pointer anyway for that the size of empty struct in c++
is 1 byte, which could lead to va_list getting out of sync. Fix #86057.
|
|
For pointer types the indices are restricted to one integer-like
operand.
For opaque types no further restrictions are made.

One or two of the tests need slight tweaks to make them pass when
building with musl.
This patch is a re-application of b61fb18 which was reverted in 0847c90
because it broke the build.

Reenables b31414bf4f9898f7817a9fcf8a91f62ec26f3eaf.
Also adds a new warning for missing `--symbol-graph-dir` arg when
`--emit-extension-symbol-graphs` is provided. This also reverts the
commit that removed.

We were generating "" (the empty string) as an alias for a bunch of FLAT
instructions, which had no effect except to cause tablegen to generate
some very long if-else chains in the generate AsmMatcher.

This was part of https://github.com/llvm/llvm-project/pull/85050.
It is suggested to split the unrelated change as much as possible. So
here is the patch.

'-fmodule-output' with non-module input
We required the file name of an 'importable module unit' should end
with .cppm (or .ccm, .cxxm, .c++m).
But the driver can accept '-fmodule-output' for files with normal
suffixes (e.g., .cpp). This is somewhat inconsistency.
In this patch, we only claim the option `-fmodule-output` is used if
the type of the input file is modules related. Then now the compiler
will emit 'unused argument' warnings if the input file is not modules
related.

This tries to fill in the basic vector handling for sadd_sat/uadd_sat
and ssub_sat/usub_sat. It just handles the basics, marking legal types
and clamping illegally sized vectors to legal ones.

We have many problems to use CodeView for a win32-elf target, e.g.,
#87140 and `error: .seh_* directives are not supported on this target`.
Fixes: #87140

Now the `DeclContext::noload_lookup()` asserts that 'this' is not a
transparent context. However, this is not consistent with
`DeclContext::lookup()`, which will lookup into its parent context if
'this' is a transparent context.
This patch makes the behavior of `DeclContext::noload_lookup()` to be
consistent with `DeclContext::lookup()`, to lookup into the parent
context if 'this' is a transparent context.
