I'd rather keep the %clang_cl tests in test/Driver, though.

r244097 - Add -gcodeview and -gdwarf to control which type Clang emits
Author: rnk
Date: Wed Aug 5 13:51:13 2015
New Revision: 244097
URL: http://llvm.org/viewvc/llvm-project?rev=244097&view=rev
Log:
Add -gcodeview and -gdwarf to control which type Clang emits
Summary:
By default, 'clang' emits dwarf and 'clang-cl' emits codeview. You can
force emission of one or both by passing -gcodeview and -gdwarf to
either driver.

Revert r339623 "Model type attributes as regular Attrs."
This breaks compiling atlwin.h in Chromium. I'm sure the code is invalid
in some way, but we put a lot of work into accepting it, and I'm sure
rejecting it was not an intended consequence of this refactoring. :)

Re: r339629 - [analyzer] [NFC] Introduce separate targets for testing the analyzer: check-clang-analyzer and check-clang-analyzer-z3
After this, check-clang no longer worked, it emitted a fatal error because
USE_Z3_SOLVER was not in lit_config.params. I worked around it in r339728,
but you might want to double check it.

r340079 - [MS] Mangle a hash of the main file path into anonymous namespaces
Author: rnk
Date: Fri Aug 17 13:59:27 2018
New Revision: 340079
URL: http://llvm.org/viewvc/llvm-project?rev=340079&view=rev
Log:
[MS] Mangle a hash of the main file path into anonymous namespaces
Summary:
This is needed to avoid conflicts in mangled names for codeview types in
anonymous namespaces. In CodeView, types refer to each other typically
through forward declarations, which contain mangled names. These names
have to be unique, otherwise the debugger will look up the mangled name
and find the wrong definition.
Furthermore, ThinLTO will deduplicate the types, and debug info
verification can fail when the types have the wrong sizes. This is
PR38608.
Fixes PR38609.

Log:
Fix a mangling failure on clang-cl C++17
MethodVFTableLocations in MigrosoftVTableContext contains canonicalized
decl. But, it's sometimes asked to lookup for non-canonicalized decl,
and that causes assertion failure, and compilation failure.
Fixes PR37481.

r314689 - Revert "[Sema] Warn on attribute nothrow conflicting with language specifiers"
Author: rnk

Log:
Revert "[Sema] Warn on attribute nothrow conflicting with language specifiers"
This reverts r314461.
It is warning on user code that uses END_COM_MAP(), which expands to
declare QueryInterface with conflicting exception specifers. I've spent
a while trying to understand why, but haven't been able to extract a
reduced test case. Let's revert and I'll keep trying.

r315656 - [MS] Don't bail on replacing dllimport vbase dtors with base dtors
Author: rnk
Date: Thu Oct 12 17:53:02 2017
New Revision: 315656
URL: http://llvm.org/viewvc/llvm-project?rev=315656&view=rev
Log:
[MS] Don't bail on replacing dllimport vbase dtors with base dtors
Fix PR32990 by effectively reverting r283063 and solving it a different
way.
We want to limit the hack to not replace equivalent available_externally
dtors specifically to libc++, which uses always_inline. It seems certain
versions of libc++ do not provide all the symbols that an explicit
template instantiation is expected to provide.
If we get to the code that forms a real alias, only *then* check if this
is available_externally, and do that by asking a better question, which
is "is this a declaration for the linker?", because *that's* what means
we can't form an alias to it.
As a follow-on simplification, remove the InEveryTU parameter. Its last
use guarded this code for forming aliases, but we should never form
aliases to declarations, regardless of what we know about every TU.

r337616 - [codeview] Don't emit variable templates as class members
Author: rnk
Date: Fri Jul 20 13:55:00 2018
New Revision: 337616
URL: http://llvm.org/viewvc/llvm-project?rev=337616&view=rev
Log:
[codeview] Don't emit variable templates as class members
MSVC doesn't, so neither should we.
Fixes PR38004, which is a crash that happens when we try to emit debug
info for a still-dependent partial variable template specialization.
As a follow-up, we should review what we're doing for function and class
member templates. It looks like we don't filter those out, but I can't
seem to get clang to emit any.

r338083 - [MS] Add L__FUNCSIG__ for compatibility
Author: rnk
Date: Thu Jul 26 16:18:44 2018
New Revision: 338083
URL: http://llvm.org/viewvc/llvm-project?rev=338083&view=rev
Log:
[MS] Add L__FUNCSIG__ for compatibility
Clang already has L__FUNCTION__ as a workaround for dealing with
pre-processor code that expects to be able to do L##__FUNCTION__ in a
macro. This patch implements the same logic for __FUNCSIG__.
Fixes PR38295.

r324913 - [Sema] Don't mark plain MS enums as fixed
Author: rnk
Date: Mon Feb 12 09:37:06 2018
New Revision: 324913

Log:
[Sema] Don't mark plain MS enums as fixed
Summary:
This fixes a flaw in our AST: PR27098
MSVC always gives plain enums the underlying type 'int'. Clang does this
as well, but we claim the enum is "fixed", as if the user actually wrote
': int'. It means we end up emitting spurious -Wsign-compare warnings on
code like this:
enum Vals { E1, E2, E3 };
bool f(unsigned v1, Vals v2) {
return v1 == v2;
}
We think 'v2' can take on negative values because we think 'Vals' is
fixed. This fixes that.

r325375 - [MS] Make constexpr static data members implicitly inline
Author: rnk

New Revision: 325375

Log:
[MS] Make constexpr static data members implicitly inline
This handles them exactly the same way that we handle const integral
static data members with inline definitions, which is what MSVC does.
As a follow-up, now that we have a way to mark variables inline in the
AST, we should consider marking them implicitly inline there instead of
only treating them as inline in CodeGen. Unfortunately, this breaks a
lot of dllimport test cases, so that is future work for now.
Fixes PR36125.

Re-land "Emit proper CodeView when -gcodeview is passed without the cl driver."
Reverts r326116 and re-lands r326113 with a fix to ASan so that it
enables column info in its test suite.

Re: r303798 - For Microsoft compatibility, set fno_operator_names
I agree with Nico in retrospect. Setting -fno-operator-names is too big a
hammer. Instead we should add some MSVCCompat hacks to pretend we saw an
identifier token instead of a keyword token when these keywords are used as
declarators.

r304012 - Enable __float128 for mingw for GCC compatibility and define __SIZEOF_FLOAT128__ on x86

Enable __float128 for mingw for GCC compatibility and define
__SIZEOF_FLOAT128__ on x86
GCC defines __FLOAT128__ on Power and __SIZEOF_FLOAT128__ on x86. We're
just following the inconsistency for now so users have some way to test.
Effectively merges this patch as requested by Martell Malone:

r304316 - [clang-cl] Implement /diagnostic: flag

[clang-cl] Implement /diagnostic: flag
This flag has three possible values: caret, column, and classic.
"caret" corresponds to clang's default mode, "column" removes the caret
and code snippet, and "classic" emits nothing.
Documentation is here:

r304335 - Don't try to spill static allocas when emitting expr cleanups with branches
Author: rnk
Date: Wed May 31 14:59:41 2017
New Revision: 304335
URL: http://llvm.org/viewvc/llvm-project?rev=304335&view=rev
Log:
Don't try to spill static allocas when emitting expr cleanups with branches
Credit goes to Gor Nishanov for putting together the fix in
https://reviews.llvm.org/D33733!
This patch is essentially me patching it locally and writing some test
cases to convince myself that it was necessary for GNU statement
expressions with branches as well as coroutines. I'll ask Gor to land
his patch with just the coroutines test.
During LValue expression evaluation, references can be bound to
anything, really: call results, aggregate temporaries, local variables,
global variables, or indirect arguments. We really only want to spill
instructions that were emitted as part of expression evaluation, and
static allocas are not that.

r305224 - Correct debug info bit offset calculation for big-endian targets
Author: rnk
Date: Mon Jun 12 14:57:56 2017
New Revision: 305224
URL: http://llvm.org/viewvc/llvm-project?rev=305224&view=rev
Log:
Correct debug info bit offset calculation for big-endian targets
Summary:
The change "[CodeView] Implement support for bit fields in
Clang" (r274201, https://reviews.llvm.org/rL274201) broke the
calculation of bit offsets for the debug info describing bitfields on
big-endian targets.
Prior to commit r274201 the debug info for bitfields got their offsets
from the ASTRecordLayout in CGDebugInfo::CollectRecordFields(), the
current field offset was then passed on to
CGDebugInfo::CollectRecordNormalField() and used directly in the
DIDerivedType.
Since commit r274201, the bit offset ending up in the DIDerivedType no
longer comes directly from the ASTRecordLayout. Instead
CGDebugInfo::CollectRecordNormalField() calls the new method
CGDebugInfo::createBitFieldType(), which in turn calls
CodeGenTypes::getCGRecordLayout().getBitFieldInfo() to fetch a
CGBitFieldInfo describing the field. The 'Offset' member of
CGBitFieldInfo is then used to calculate the bit offset of the
DIDerivedType. Unfortunately the previous and current method of
calculating the bit offset are only equivalent for little endian
targets, as CGRecordLowering::setBitFieldInfo() reverses the bit
offsets for big endian targets as the last thing it does.
A simple reproducer for this error is the following module:
struct fields {
unsigned a : 4;
unsigned b : 4;
} flags = {0x0f, 0x1};
Compiled for Mips, with commit r274200 both the DIDerivedType bit
offsets on the IR-level and the DWARF information on the ELF-level
will have the expected values: the offsets of 'a' and 'b' are 0 and 4
respectively. With r274201 the offsets are switched to 4 and 0. By
noting that the static initialization of 'flags' in both cases is the
same, we can eliminate a change in record layout as the cause of the
change in the debug info. Also compiling this example with gcc,
produces the same record layout and debug info as commit r274200.
In order to restore the previous function we extend
CGDebugInfo::createBitFieldType() to compensate for the reversal done
in CGRecordLowering::setBitFieldInfo().

Re: r284060 - Implement MS _BitScan intrinsics
We should fix it. We just need a new character code in the builtin function prototype encoding. Currently there is no encoding for a portable int32_t that magically becomes "long" on 32-bit Windows. The closest thing we have is 'W', which is used by Neon intrinsics to select between "long" and "long long". It was added in r202004.

[MS] Don't statically initialize dllimport member function pointers
We were already applying the same rules to dllimport function pointers.
David Majnemer added that logic back in r211677 to fix PR20130. We
failed to extend that logic to non-virtual member function pointers,
which are basically function pointers in a struct with some extra
offsets.
Fixes PR33570.

r320730 - [CodeGen][X86] Implement _InterlockedCompareExchange128 intrinsic
Author: rnk
Date: Thu Dec 14 11:00:21 2017
New Revision: 320730
URL: http://llvm.org/viewvc/llvm-project?rev=320730&view=rev
Log:
[CodeGen][X86] Implement _InterlockedCompareExchange128 intrinsic
Summary:
InterlockedCompareExchange128 is a bit more complicated than the other
InterlockedCompareExchange functions, so it requires a bit more work. It
doesn't directly refer to 128bit ints, instead it takes pointers to
64bit ints for Destination and ComparandResult, and exchange is taken as
two 64bit ints (high & low). The previous value is written to
ComparandResult, and success is returned. This implementation does the
following in order to produce a cmpxchg instruction:
1. Cast everything to 128bit ints or int pointers, and glues together
the Exchange values
2. Reads from CompareandResult to get the comparand
3. Calls cmpxchg volatile (on X86 this will produce a lock cmpxchg16b
instruction)
1. Result 0 (previous value) is written back to ComparandResult
2. Result 1 (success bool) is zext'ed to a uchar and returned

Re: r326141 - Re-land "Emit proper CodeView when -gcodeview is passed without the cl driver."
I want to do that, but it will surely break the LLDB test suite, which
assumes `clang -g` makes dwarf. It's just a matter of fixing up the flags
their test makefiles use.

r326622 - Don't claim that va_start has special semantic checks
Author: rnk
Date: Fri Mar 2 13:41:08 2018
New Revision: 326622
URL: http://llvm.org/viewvc/llvm-project?rev=326622&view=rev
Log:
Don't claim that va_start has special semantic checks
We don't have special checks for BI_va_start in
Sema::CheckBuiltinFunctionCall, so setting the 't' flag for va_start in
Builtins.def disables semantic checking for it. That's not desired, and
IRGen crashes when it tries to generate a call to va_start that doesn't
have at least one argument.

r326926 - Push a function scope when parsing function bodies without a declaration
Author: rnk
Date: Wed Mar 7 10:55:10 2018
New Revision: 326926
URL: http://llvm.org/viewvc/llvm-project?rev=326926&view=rev
Log:
Push a function scope when parsing function bodies without a declaration
Summary:
This is PR36536.
There are a few ways to reach Sema::ActOnStartOfFunctionDef with a null
Decl. Currently, the parser continues on to attempt to parse the
statements in the function body without pushing a function scope or
declaration context. However, lots of statement parsing logic relies on
getCurFunction() returning something reasonable. It turns out that
getCurFunction() will never return null today because of an optimization
where Sema pre-allocates one FunctionScopeInfo and reuses it when
possible. This goes wrong when something inside the function body causes
us to push another function scope, such as requiring an implicit
definition of a special member function. Reusing the state clears it
out, which will lead to bugs. In PR36536, we found that the SwitchStack
gets unbalanced, because we push a switch, clear out the stack, and then
try to pop a switch that isn't there.
As a follow-up, I plan to move the pre-allocated FunctionScopeInfo out
of the FunctionScopes stack. This means the FunctionScopes stack will
often be empty, and callers of getCurFunction() will need to check for
null.

r326957 - Avoid including ScopeInfo.h from Sema.h
Author: rnk

Log:
Avoid including ScopeInfo.h from Sema.h
Summary:
This provides no measurable build speedup, but it reinstates an
optimization from r112038 that was lost in r179618. It requires moving
CapturedScopeInfo::Capture out to clang::sema, which might be too
general since we have plenty of other Capture records in BlockDecl and
other AST nodes.

r326965 - [Sema] Make getCurFunction() return null outside function parsing
Author: rnk
Date: Wed Mar 7 16:14:34 2018
New Revision: 326965
URL: http://llvm.org/viewvc/llvm-project?rev=326965&view=rev
Log:
[Sema] Make getCurFunction() return null outside function parsing
Summary:
Before this patch, Sema pre-allocated a FunctionScopeInfo and kept it in
the first, always present element of the FunctionScopes stack. This
meant that Sema::getCurFunction would return a pointer to this
pre-allocated object when parsing code outside a function body. This is
pretty much always a bug, so this patch moves the pre-allocated object
into a separate unique_ptr. This should make bugs like PR36536 a lot
more obvious.
As you can see from this patch, there were a number of places that
unconditionally assumed they were always called inside a function.
However, there are also many places that null checked the result of
getCurFunction(), so I think this is a reasonable direction.

We already have a mangling for the __unaligned qualifier, we just have
to call Qualifiers::getFromCVRUMask instead of getFromCVRMask.

r326974 - Revert "[Sema] Make getCurFunction() return null outside function parsing"

Revert "[Sema] Make getCurFunction() return null outside function parsing"
This reverts r326965. It seems to have caused repeating test failures in
clang/test/Sema/diagnose_if.c on some buildbots.
I cannot reproduce the problem, and it's not immediately obvious what
the problem is, so let's revert to green.

r327334 - Re-land "[Sema] Make getCurFunction() return null outside function parsing"

Log:
Re-land "[Sema] Make getCurFunction() return null outside function parsing"
This relands r326965.
There was a null dereference in typo correction that was triggered in
Sema/diagnose_if.c. We are not always in a function scope when doing
typo correction. The fix is to add a null check.
LLVM's optimizer made it hard to find this bug. I wrote it up in a
not-very-well-editted blog post here:

r327732 - [MS] Always use base dtors in place of complete/vbase dtors when possible
Author: rnk
Date: Fri Mar 16 12:40:50 2018
New Revision: 327732
URL: http://llvm.org/viewvc/llvm-project?rev=327732&view=rev
Log:
[MS] Always use base dtors in place of complete/vbase dtors when possible
Summary:
Previously we tried too hard to uphold the fiction that destructor
variants work like they do on Itanium throughout the ABI-neutral parts
of clang. This lead to MS C++ ABI incompatiblities and other bugs. Now,
-mconstructor-aliases will no longer control this ABI detail, and clang
-cc1's LLVM IR output will be this much closer to the clang driver's.
Based on a patch by Zahira Ammarguellat:
https://reviews.llvm.org/D39063
I've tried to move the logic that Zahira added into MicrosoftCXXABI.cpp.
There is only one ABI-specific detail sticking out, and that is in
CodeGenModule::getAddrOfCXXStructor, where we collapse complete dtors to
base dtors in the MS ABI.
This fixes PR32990.

r333958 - Revert r333791 "Cap "voluntary" vector alignment at 16 for all Darwin platforms."
Author: rnk

Log:
Revert r333791 "Cap "voluntary" vector alignment at 16 for all Darwin
platforms."
Adding __attribute__((aligned(32))) to __m256 breaks the implementation
of _mm256_loadu_ps on Windows. On Windows, alignment attributes have
higher precedence than packing attributes.
We also might want to carefully consider the consequences of changing
our vector typedefs, since many users copy them and invent their own
new, non-Intel specific vector type names.

r333978 - Reimplement the bittest intrinsic family as builtins with inline asm
Author: rnk
Date: Mon Jun 4 18:33:40 2018
New Revision: 333978
URL: http://llvm.org/viewvc/llvm-project?rev=333978&view=rev
Log:
Reimplement the bittest intrinsic family as builtins with inline asm
We need to implement _interlockedbittestandset as a builtin for
windows.h, so we might as well do the whole family. It reduces code
duplication anyway.
Fixes PR33188, a long standing bug in our bittest implementation
encountered by Chakra.

r334059 - Implement bittest intrinsics generically for non-x86 platforms
Author: rnk
Date: Tue Jun 5 18:35:08 2018
New Revision: 334059
URL: http://llvm.org/viewvc/llvm-project?rev=334059&view=rev
Log:
Implement bittest intrinsics generically for non-x86 platforms
I tested these locally on an x86 machine by disabling the inline asm
codepath and confirming that it does the same bitflips as we do with the
inline asm.
Addresses code review feedback.

r334239 - [MS] Re-add support for the ARM interlocked bittest intrinscs
Author: rnk

New Revision: 334239

Log:
[MS] Re-add support for the ARM interlocked bittest intrinscs
Adds support for these intrinsics, which are ARM and ARM64 only:
_interlockedbittestandreset_acq
_interlockedbittestandreset_rel
_interlockedbittestandreset_nf
_interlockedbittestandset_acq
_interlockedbittestandset_rel
_interlockedbittestandset_nf
Refactor the bittest intrinsic handling to decompose each intrinsic into
its action, its width, and its atomicity.

r334417 - [MS] Use mangled names and comdats for string merging with ASan

Log:
[MS] Use mangled names and comdats for string merging with ASan
This should reduce the binary size penalty of ASan on Windows. After
r334313, ASan will add red zones to globals in comdats, so we will still
find OOB accesses to string literals.

Re: r334494 - Re-apply r334418 "Enable crash recovery tests on Windows, globs work in the lit internal shell now"
The length of that path is about 257, or very near MAX_PATH, which suggests
that the version of rm you are using does not tolerate deep paths. This has
been a long standing problem, and our solution to it was to install a
special version of rm.exe on all of our buildbots that reliably handles
long paths and copes with virus scanners and things.
We may try to fix this in lit by reimplementing 'rm' in python, but that is
not a near term solution.

Re: [clang-tools-extra] r334807 - [clangd] Do not report comments that only have special chars.
This test has been failing on Windows since it has been added:
http://lab.llvm.org:8011/builders/clang-x86-windows-msvc2015/builds/12549
I took a look at the unittest code, but I'm not familiar enough with this
code to debug it. Can you take a look at this?

Re: [clang-tools-extra] r334807 - [clangd] Do not report comments that only have special chars.
And, as soon as I sent that, I realized what was up. Apparently
auto-complete is driven by the parser, and delayed template parsing means
we don't parse templates. That seems like a serious issue that should get
fixed eventually.
Anyway, I landed a crummy workaround in r334973 to green the bots.
