Eli Friedman 37a8197b61 Add a small transform: transform -(X<<Y) to (-X<<Y) when the shift has a single 
use and X is free to negate.

Sean Callanan 9aeccadce4 Moved InstallLexer() from the X86-specific AsmLexer 
to the TargetAsmLexer class so that clients can
actually use the TargetAsmLexer they get from a
Target.

Anders Carlsson 600f737b95 When doing a base-to-derived cast we don't need to null check the derived value if the class offset is 0.

Anders Carlsson 84673e200f Some class related cleanup.

Evan Cheng d86d3fe0c3 Do not mark no-return calls tail calls. It'll screw up special calls like longjmp and it doesn't make much sense for performance reason. If my logic is faulty, please let me know.

Daniel Dunbar 288edb5bda cindex/Python: Turn off showing IDs by default, they are really slow to compute 
pending a hash function. Also added a --max-depth argument, handy for timing and
limiting the volume of output.

Daniel Dunbar baf33fc56f CIndex/USRs: Disable a bogus assert, we don't want CIndex to crash liberally. I 
have sent Ted a test case for this.

Daniel Dunbar 45dc842a0e cindex/Python: Add a simple example which dumps assorted information about a translation unit. 
llvm-svn: 94934
 2010-01-30 23:59:14 +00:00
Daniel Dunbar a7a354e3e3 cindex/Python: Add full support for Diagnostic and FixIt objects, available via TranslationUnit.diagnostics. 
Several important FIXMEs remain:
  - We aren't getting all the notes?
  - There is still no way to get diagnostics for invalid inputs.

Daniel Dunbar 15635b8f5c cindex/Python: Update SourceLocation and SourceRange structures to match API changes. 
Hurray for exposing implementation details!!!

Daniel Dunbar 1e079a48ad cindex/Python: Update Index.create for removal of displayDiagnostics.

Daniel Dunbar 9ee3a92a75 CIndex: Fix diagnostic callback to not return SourceLocations with a reference to a temporary LangOptions object. 
llvm-svn: 94928
 2010-01-30 23:31:49 +00:00
Daniel Dunbar 854d36bd9b CIndex: Fix ReportSerializedDiagnostics to honor the DiagnosticClient contract 
that diagnostics with a source location should occur inside
{Begin,End}SourceFile.

Note that code completion is currently passing in an invalid LangOptions object
due to its implementation, I need to sort this out with Doug.

Anders Carlsson 98323d29b6 Remove the SmallVectors from AsmStmt. Fixes PR6105. 
llvm-svn: 94926
 2010-01-30 23:19:41 +00:00
Anders Carlsson 9a020f9a3a Use IdentifierInfo * instead of std::string for the AsmStmt names.

Daniel Dunbar 6b03ecef0d ASTUnit: Ensure the CompilerInvocation object used in LoadFromCommandLine is 
live as long as the ASTUnit. This is useful for clients which want to maintain
pointers to the LangOptions object which ultimately lives in the
CompilerInvocation, although it would be nice to make all of this ownership
stuff more explicit and obvious.

llvm-svn: 94924
 2010-01-30 21:47:16 +00:00
Daniel Dunbar 6824225465 CompilerInstance: Change to not contain the CompilerInvocation object. 
This allows clients to install their own CompilerInvocation object, which is
important for clients that may wish to create references to things like
LangOptions whose lifetime will extend past that of the CompilerInstance.

Anders Carlsson bd32c434ae Add an assert to make sure that we don't try to mess with overridden methods for class templates. 
llvm-svn: 94907
 2010-01-30 17:42:34 +00:00
Benjamin Kramer 2ecf8eb2dc PCHReader doesn't implement classof so dyn_casting it will do really weird stuff. Use a static_cast instead. 
I don't know if this hack is the right fix. Doug, please take a look.

Daniel Dunbar 19b70bd46c Recognize 'q' as a format length modifier (from BSD).

Benjamin Kramer 842bf17366 Use StringRef instead of returning a temporary std::string. 
This fixes a really nasty bug in Darwin::getDarwinArchName where we were going
StringRef -> temporary std::string -> StringRef (and return the dead StringRef).
The StringRefs from Triple live as long as the Triple itself, that should be
long enough.

Hopefully 2 of 4 MSVC buildbot failures are gone now.

Anton Korobeynikov 25df248382 Fix a gross typo: ARMv6+ may or may not support unaligned memory operations. 
Even if they are suported by the core, they can be disabled
(this is just a configuration bit inside some register).

Allow unaligned memops on darwin and conservatively disallow them otherwise.

 2010-01-30 14:08:12 +00:00
Benjamin Kramer a87bdb793e We don't need to place 0 in the URL string now that we return a StringRef. 
- URL can go into read only memory now.
- Compilers will fold away all the strstr calls.

Bob Wilson 56600a15ad Check alignment of loads when deciding whether it is safe to execute them 
unconditionally.  Besides checking the offset, also check that the underlying
object is aligned as much as the load itself.

Evan Cheng 70f714fdbe Allow more tailcall optimization: calls with inputs that are all passed in registers. 
llvm-svn: 94873
 2010-01-30 01:22:00 +00:00
Evan Cheng 2d5a75b42a Don't forget to transfer target flag when inserting a tailcall instruction.

Daniel Dunbar 76e5d70c57 MC/X86 AsmParser: Handle absolute memory operands correctly. We were doing 
something totally broken and parsing them as immediates, but the .td file also
had the wrong match class so things sortof worked. Except, that is, that we
would parse
  movl $0, %eax
as
  movl 0, %eax
Feel free to guess how well that worked.

Daniel Dunbar cf18153de2 AsmMatcher: Create operand classes before use, apparently records aren't visited 
in the order they were declared.

llvm-svn: 94863
 2010-01-30 00:41:10 +00:00
Bob Wilson 2e51136f80 Remove ARM-specific calling convention from this test. Target data is 
needed for this test, but otherwise, there's nothing ARM-specific about
it and no need to specify the calling convention.
