The argument range checks for the HTM and Crypto builtins were implemented in
CGBuiltin.cpp, not in Sema. This change moves them to the appropriate location
in SemaChecking.cpp. It requires the creation of a new method in the Sema class
to do checks for PPC-specific builtins.

Update lib/IR and lib/Bitcode to use the new `DebugLoc` API. Added an
explicit conversion to `bool` (avoiding a conversion to `MDLocation`),
since a couple of these use cases need to handle broken code.

Adds a test to verify the behavior that r233153 restored: 'optnone'
does not spuriously disable the DAG combiner, and in fact there are
cases where the DAG combiner must run (even at -O0 or 'optnone') in
order for codegen to succeed.

When a new SM architecture is introduced, it is only supported by the
current PTX version and later. Make sure we are using at least the
minimum PTX version for the target architecture.
This also removes support for PTX ISA < 3.2.

There was a change to the way some of the HTM and crypto builtins are being
handled in Clang. Previously, some of the builtins were dealt with in the
CodeGenFunction::EmitPPCBuiltinExpr method (in order to do range checking on
constant arguments). These check will been moved to Sema
http://reviews.llvm.org/D8672), which means those builtins will not be handled
in the EmitPPCBuiltinExpr method anymore. As a result, the definition of the
intrinsics in IntrinsicsPowerPC.td needs to be modified to inherit from the
GCCBuiltin definition.

Test cases must not check for symbolic variable names that are not
present in IR generated by no-assert builds.
Fixed by testing a more complete subset of the va_arg dataflow,
without relying on variable names.

Rewrite `DebugLoc` with a cleaner API that reflects its current status
as a wrapper around an `MDLocation` pointer.
- Add accessors/constructors to/from `MDLocation`.
- Simplify construction from `MDNode`.
- Remove unnecessary `LLVMContext` from APIs.
- Drop some API that isn't useful any more.
- Rewrite documentation.
Actually, I've left the old API behind temporarily at the bottom of the
class so that I can update callers in separate commits. I'll remove it
once the callers are updated.

We do not have buildbots or anything that tests this functionality, hence it
most likely bitrots. People interested to use this functionality can always
recover it from svn history.

Write `MDLocation::getInlinedAtScope()` and use it to re-implement
`DebugLoc::getScopeNode()` (and simplify `DISubprogram::Verify()`).
This follows the inlined-at linked list and returns the scope of the
deepest/last location.
llvm-svn: 233568
This allows us to delinerize code such as:
A[][n]
for (i
for (j
A[i][n-j-1] = ...
which would previously have been delinearize to an access A[i+1][-j-1].
To recover the correct access we apply the piecewise expression:
{ A[i][j] -> A[i-1][i+N]: i < 0; A[i][j] -> A[i][i]: i >= 0}
This approach generalizes to higher dimensions.
llvm-svn: 233566
Add operand checks for `MDLexicalBlock` and `MDLexicalBlockFile`. Like
`MDLocalVariable` and `MDLocation`, these nodes always require a scope.
There was no test bitrot to fix here (just updated the serialization
tests in test/Assembler/mdlexicalblock.ll).
llvm-svn: 233561
Momentarily (but never in tree), the `scope:` field was called
`parent:`. Apparently a few testcases were left behind with "parent" in
the name, so rename them.
llvm-svn: 233560
Check operands of `MDSubprogram`s in the verifier, and update the
accessors and factory functions to use more specific types.
There were a lot of broken testcases, which I fixed in r233466. If you
have out-of-tree tests for debug info, you probably need similar changes
to the ones I made there.

Summary:
Currently the conversion check does not take place in a context where access control SFINAE is applied. This patch changes the context of the test expression so that SFINAE occurs if access control does not permit the conversion.

Adds @skipIfPlatform and @skipUnlessPlatform decorators which will skip if /
unless the target platform is in the provided platform list.
Test Plan:
ninja check-lldb shows no regressions.
When running cross platform, tests which cannot run on the target platform are
skipped.

Like on other 64-bit platforms, Int64Type should be SignedLong
on SystemZ, not SignedLongLong as per default. This could cause
ABI incompatibilities in certain cases (e.g. name mangling).
llvm-svn: 233544
Running the GCC's inter-compiler ABI compatibility test suite uncovered
a couple of errors in clang's SystemZ ABI implementation. These all
affect only rare corner cases:
- Short vector types
GCC synthetic vector types defined with __attribute__ ((vector_size ...))
are always passed and returned by reference. (This is not documented in
the official ABI document, but is the de-facto ABI implemented by GCC.)
clang would do that only for vector sizes >= 16 bytes, but not for shorter
vector types.
- Float-like aggregates and empty bitfields
clang would consider any aggregate containing an empty bitfield as
first element to be a float-like aggregate. That's obviously wrong.
According to the ABI doc, the presence of an empty bitfield makes
an aggregate to be *not* float-like. However, due to a bug in GCC,
empty bitfields are ignored in C++; this patch changes clang to be
compatible with this "feature" of GCC.
- Float-like aggregates and va_arg
The va_arg implementation would mis-detect some aggregates as float-like
that aren't actually passed as such. This applies to aggregates that
have only a single element of type float or double, but using an aligned
attribute that increases the total struct size to more than 8 bytes.
This error occurred because the va_arg implement used to have an copy
of the float-like aggregate detection logic (i.e. it would call the
isFPArgumentType routine, but not perform the size check).
To simplify the logic, this patch removes the duplicated logic and
instead simply checks the (possibly coerced) LLVM argument type as
already determined by classifyArgumentType.
llvm-svn: 233543
Compiling the following function with -O0 would crash, since LLVM would
hit an assertion in getTestUnderMaskCond:
int test(unsigned long x)
{
return x >= 0 && x <= 15;
}
Fixed by detecting the case in the caller of getTestUnderMaskCond.
llvm-svn: 233541
These sections are never looked up and we know when have to create them. Use
that to save adding them to the regular map and avoid a symbol->string->symbol
conversion for the group symbol.
This also makes the implementation independent of the details of how unique
sections are implemented.
llvm-svn: 233539
Summary:
The 'R' constraint is actually supposed to be much more complicated than
this and is defined in terms of whether it will cause macro expansion in
the assembler. 'R' is getting less useful due to architecture changes and
ought to be replaced by other constraints. We therefore implement 9-bit
offsets which will work for all subtargets and all instructions.
