[X86] Avoid mangling frameescape labels

mistakenly being applied to frameescape labels, which are not externally
visible global symbols. They use the private global prefix 'L'.

The *right* way to fix this is probably to stop masquerading this label
as an ExternalSymbol and create a new SDNode type. These labels are not
"external", and we know they will be resolved by assembly time. Having a
custom SDNode type would allow us to do better X86 address mode

this has all baked for about a week.

you get everything compiling and tests passing with the *previous*

filtered through clang-format-diff.py.  I edited the tests for
test/Assembler/invalid-generic-debug-node-*.ll by hand since the columns
were off-by-three.  It should work on your out-of-tree testcases (and
code, if you've followed the advice in the previous paragraph).

Some of the tests are in badly named files now (e.g.,
test/Assembler/invalid-mdcompositetype-missing-tag.ll should be
'dicompositetype'); I'll come back and move the files in a follow-up

Debug Info: Represent local anonymous unions as anonymous unions

Besides being morally wrong, the existing representation using local
variables breaks internal assumptions about the local variables' storage
size.

Compiling

```
   void fn1() {

the 32-bit storage for the "local variable" c into two pieces because the
second piece is clearly outside the 8-bit range that is expected for a
variable of type char. Given the choice I'd rather fix the debug
representation than weaken the verifier.

Debuggers generally already know how to deal with anonymous unions when
they are members of C++ record types, but they may have problems finding

This change is the first of 3 patches to add support for specifying
the profile output from the command line via -fprofile-instr-generate=<path>,
where the specified output path/file will be overridden by the
LLVM_PROFILE_FILE environment variable.

Several changes are made to the runtime to support this:

Add a new interface __llvm_profile_override_default_filename that will
set the profile output filename, but allows LLVM_PROFILE_FILE to override.
This is the interface used by the new option.

Refactor the pid-expansion done for LLVM_PROFILE_FILE into a separate
routine that can be shared by the various filename setting routines
(so that the filename from the option can also use the "%p" syntax).

Move the truncation into setFilename, and only truncate if there is a
new filename specified (to maintain support for appending to the same
profile file in the case of multiple shared objects built with profiling).

Move the handling for a NULL filename passed to __llvm_profile_set_filename and
__llvm_profile_override_default_filename into the new setFilenamePossiblyWithPid
routine. This now correctly resets the output file to default.profraw
instead of NULL.
The handling for a null LLVM_PROFILE_FILE (which should not reset) is done
by caller setFilenameFromEnvironment.

On x86, all outlined handlers have no parameters, but they do implicitly
take the EBP value passed in and use it to address locals of the parent

transform fadd chains to increase parallelism

This is a compromise: with this simple patch, we should always handle a chain of exactly 3
operations optimally, but we're not generating the optimal balanced binary tree for a longer
sequence.

In general, this transform will reduce the dependency chain for a sequence of instructions
using N operands from a worst case N-1 dependent operations to N/2 dependent operations.
The optimal balanced binary tree would reduce the chain to log2(N).

The trade-off for not dealing with longer sequences is: (1) we have less complexity in the
compiler, (2) we avoid unknown compile-time blowup calculating a balanced tree, and (3) we
don't need to worry about the increased register pressure required to parallelize longer
sequences. It also seems unlikely that we would ever encounter really long strings of
dependent ops like that in the wild, but I'm not sure how to verify that speculation.
FWIW, I see no perf difference for test-suite running on btver2 (x86-64) with -ffast-math
and this patch.

- When importing functions, the body (if any) was

  body is imported also.

- When a function-local Decl is imported, the first
  thing the ASTImporter does is import its context
  (via ImportDeclParts()).  This can trigger
  importing the Decl again as part of the body of
  the function (but only once, since the function's
  Decl has been added to ImportedDecls).  This patch
  fixes that problem by extending ImportDeclParts()
  to return the imported Decl if it was imported as
  part of importing its context, and the patch adds
  ASTImporter::GetAlreadyImportedOrNull() to support
  this query.  All callers of ImportDeclParts return
  the imported version of the Decl if ImportDeclParts()
  returns it.

- When creating functions, InnerLocStart of the source
  function was re-used without importing.  This is a
  straight up bug, and this patch makes ASTImporter
  import the InnerLocStart and use the imported version.

- When importing FileIDs, the ASTImporter previously
  always tried to re-load the file for the corresponding
  CacheEntry from disk.  This doesn't work if the
  CacheEntry corresponds to a named memory buffer.  This

Combine instantiation context of field initializer with context of class.

Inclass initializer is instantiated in its own LocalInstantiationScope. It
causes problems when instantiating local classes - when instantiation scope
is searched for DeclContext of the field, the search fails. As a solution,
the instantiation scope of field initializer is combined with its outer
scope.

This patch fixes PR23194.

9 years agoR600/SI: Add a lower case alias for subtarget feature: +DumpCode

R600/SI: Add a lower case alias for subtarget feature: +DumpCode

llc converts all feature strings to lower case, while the LLVM C API
does not, so we need a lower case alias in order to test this with llc.
