- Functional for simple cases but there are some glaring omissions
(protocols, properties, and other language extensions).
- The code needs a fair bit of cleaning.
llvm-svn: 55108
scripts dir appear before the user path.
- This is an attempt to pick up the right executables. We should
probably be substituting the exact things we want for clang a la
the LLVM test script.

difference from generic x86 is the defines. The rest is non-trivial to
implement.
I'm not planning on adding any more targets myself; if there are any
targets anyone is currently using that are missing, feel free to add
them, or ask me to add them.
This concludes the work I'm planning for the TargetInfo
implementations at the moment; all the other issues with TargetInfo require
some API changes, and I haven't really thought it through. Some of the
remaining issues: allowing targets to define size_t and wchar_t properly,
adding some sort of __builtin_type_info intrinsic so we can finish clang's
limits.h and float.h and get rid of a massive number of macro
definitions, allowing target-specific command-line options, allowing
target-specific defaults for certain command-line options like
-fms-extensions, exposing vector alignment outside of the description
string, exposing endianness outside of the description string, allowing
targets to expose special bit-field layout requirements, exposing some
sort of custom hook for call generation in CodeGen, and adding CPU
selection to control defines like __SSE__.
llvm-svn: 55098
This approach allows adding OS-specific targets/defines/etc. without
completely breaking unknown subtargets. No new subtargets yet, although
I plan to add x86-Linux soon. Others can add targets that they use as
needed; adding a new subtarget takes very little code.
Also does some fixups for description strings; a lot of them were
unspecified. I think all the ones I added are correct, but
they're unverified; corrections are welcome.
llvm-svn: 55091
cleaned it up a bit, including fixing the definition of va_list; this
shouldn't break anything, but anyone using Sparc should watch for
regressions.
llvm-svn: 55041
- UsualUnaryConversions takes an Expr *& and may modify its argument,
this broke when it was refactored into Sema::CheckCastTypes. This
meant that we were missing implicit casts in some places.
- Seems pretty sad that this got through our tests.
llvm-svn: 55039
visible effects, but this will significantly reduce the amount of
boilerplate code necessary to add subtargets.
If this looks okay, I'll do the rest of the processors (PPC, Sparc, ARM)
soon.
llvm-svn: 55036
heck it does on Darwin, but it's not part of POSIX, and the GNU version
of find errors out on it.
On a side note, there are a couple of new failures due to tests
including OS X specific headers.
llvm-svn: 55019
This patch extends BasicStoreManager::getInitialStore() to include code that symbolicates input variables.
It also removes redundant handling of ImplicitParamDecl, since it is a subclass of VarDecl.
llvm-svn: 54993
Have Declarator accept and use a 'const DeclSpec &', instead of 'DeclSpec &', to make DeclSpec's immutability more explicit.
No functionality change.
llvm-svn: 54839
Change CodeGenFunction::EmitParmDecl to take either a ParmVarDecl or an
ImplicitParamDecl.
Drop hasAggregateLLVMType from CodeGenModule.cpp (use version in
CodeGenFunction).
Change the Objective-C method generation to use EmitParmDecl for
implicit parameters.
llvm-svn: 54838
- Remove ConstNotEq from GRState/GRStateManager (!= tracking uses GDM instead).
- GRStateManager now can book-keep "contexts" (e.g., factory objects) for uses
with data elements stored into the GDM.
- Refactor pretty-printing of states to use GRState::Printer objects
exclusively. This removed a huge amount of pretty-printing logic from
GRExprEngine.
CFRefCount
- Simplified some API calls based on refinements to the GDM api.
llvm-svn: 54835
ObjCInterfaceDecl.
Change ObjCRuntime::GenerateMessageSendSuper to take the
ObjCInterfaceDecl for the super class, instead of just its name.
Change EmitObjCMessageExpr to make the right runtime calls for super
sends in class methods (i.e. a super send with the class object as
the receiver).
llvm-svn: 54833
use default APSInt constructor instead of embedding arbitrary
constant.
Update OverloadExpr::getNumArgs to use getIntegerConstantExprValue.
Update OverloadExpr::getExpr to be const.
llvm-svn: 54828
- Add CodeGenModule::EmitTopLevelDecl which uses switch on kind
instead of ugly & slow dyn_cast chains.
- Drop some simple forwarding methods into the ObjC runtime.
- Privatize appropriate methods.
llvm-svn: 54827
- This is in prep for implementation class support for the NeXT
runtime, for which the existing methods don't provide enough
information (and additionally make too many assumptions about how
things should be emitted).
llvm-svn: 54824
- Added as private members for each because it is not clear where to
put the common definition. Perhaps the IdentifierInfos all of these
"pseudo-keywords" should be collected into one place (this would
KnownFunctionIDs and Objective-C property IDs, for example).
Remove Token::isNamedIdentifier.
- There isn't a good reason to use strcmp when we have interned
strings, and there isn't a good reason to encourage clients to do
so.
llvm-svn: 54794
of using CheckerState).
Removed CheckerState from GRState.
Added class GRStateRef which wraps GRState* and GRStateManager*. This is handy
for generating new states with a single handle.
Added member template set/get functions to GRStateRef/GRState/GRStateManager for
accessing the Generic Data Map.
llvm-svn: 54788
and put the caret on the ()'s. e.g. produces:
t.c:13:9: error: called object is not a function or function pointer
((B)a)();
~~~~~~^
instead of:
t.c:13:3: error: called object is not a function or function pointer
((B)a)();
^~~~~~~~
llvm-svn: 54775
- Returns addr of constant for argument + '\0'.
- I couldn't think of a better name.
- Move appropriate users of GetAddrOfConstantString to this.
Rename getStringForStringLiteral to GetStringForStringLiteral.
Add GetAddrOfConstantStringFromLiteral
- This combines GetAddrOfConstantString and
GetStringForStringLiteral. This method can be, but is not yet, more
efficient.
Change GetAddrOfConstantString to not add terminating '\0'
- <rdar://problem/6140956>
llvm-svn: 54768
The following case resulted in an invalid start location:
// start location not being set for ObjCProtocolDecl AST (when a forward reference is in scope).
@protocol Buggy;
@protocol Buggy
@optional
- whatever;
@end
llvm-svn: 54740
ObjCProtocolDecl directly.
Implement CodeGen support for forward protocol decls (no-ops are so
nice to implement).
Also moved CGObjCRuntime.h out of CodeGenModule.h
llvm-svn: 54709
Changed CGObjCRuntime::GenerateConstantString interface to take
std::string instead of char* and size.
Change ObjC functions which call on GenerateConstantString to bitcast
result to appropriate type.
llvm-svn: 54659
- Maps to LangOptions.Exceptions
- Currently always off, should autoselect based on language.
Update CodeGen to set unwind attribute on functions definitions based
on LangOptions.Exceptions.
- Still need to set attributes appropriately on calls.
llvm-svn: 54643
- Kill unnecessary #includes in .cpp files. This is an automatic
sweep so some things removed are actually used, but happen to be
included by a previous header. I tried to get rid of the obvious
examples and this was the easiest way to trim the #includes in one
fell swoop.
- We now return to regularly scheduled development.
llvm-svn: 54632
- Drop {Decl.h,DeclObjC.h,IdentifierTable.h} from Expr.h
- Moved Sema::getCurMethodDecl() out of line (dependent on
ObjCMethodDecl via dyn_cast).
llvm-svn: 54629
temporarily, I assumed GetAddrForConstantString literal was being
used consistently but it doesn't look like it is.
Factored out a CodeGenModule::getStringForStringLiteral which handles
extracting a std::string for the bytes of a StringLiteral, padded to
match the type.
Update EmitLValue to use getStringForStringLiteral, this was
previously not padding strings correctly. Good thing we only emit
strings in 4 different places!
llvm-svn: 54621
* Move FormatError() from TextDiagnostic up to DiagClient, remove now
empty class TextDiagnostic
* Make DiagClient optional for Diagnostic
This fixes the following problems:
* -html-diags (and probably others) does now output the same set of
warnings as console clang does
* nothing crashes if one forgets to call setHeaderSearch() on
TextDiagnostic
* some code duplication is removed
llvm-svn: 54620
1) New public methods added:
-EnableBacktrackAtThisPos
-DisableBacktrack
-Backtrack
-isBacktrackEnabled
2) LookAhead() implementation is replaced with a more efficient one.
3) LookNext() is removed.
llvm-svn: 54611
member count. The count returned by numStructUnionElements is the
number of initializers that will be consumed, not the number of members
to iterate through. Fixes PR2534.
llvm-svn: 54601
Even though the test case this fixes is in "tentative-decls.c", this bug didn't have anything to do with our handling of tentative definitions (which is what I first expected). In any event, this is a tricky area of the spec.
llvm-svn: 54583
- Move checking from MergeVarDecl->FinializeDeclaratorGroup. Since MergeVarDecl is called before the initializer is attacted, it can't be done there (this removes a long standing FIXME).
- Add Sema::isTentativeDefinition() and Sema::CheckForFileScopedRedefinitions().
- Remove FIXME's and touch-up test case.
Still some more work to do (forthcoming)...
llvm-svn: 54533
The motivation is that clients may either:
(a) query the ASTConsumer object after AST parsing to collect data/etc.
(b) reuse the ASTConsumer.
llvm-svn: 54502
- Change hardcoded assembly instructions to a use of 'opt' (still
waiting for someone to yell at me for this).
- Add some cases to cover behavior fixed by previous commit.
llvm-svn: 54413
type.
- This generates somewhat less optimal code than before but this is
not hard to rectify once stable (at the cost of slightly more
complex code).
- This currently always uses little-endian ordering of the bitfield.
- This breaks the CodeGen/bitfield.c test because it was grepping for
hard-coded assembly instructions. Will fix once a better test case
is constructed (hard to do without execution).
- This fixes SingleSource/UnitTests/2006-01-23-InitializedBitField.c
and Regression/C/PR1386.c from the test suite.
- <rdar://problem/6085090>, <rdar://problem/6094169>
llvm-svn: 54395
- Changed EmitSub to work on all cases (arithmetic, ptr - int, ptr -
ptr) so that implementation matches that of other operators.
- Modify EmitCompoundAssign to compute and perform the appropriate
casts of left, right, and result types for the assorted pointer
arithmetic cases.
- Fix EmitSub (ptr - int) case to negate the rhs *after*
extension. This is critical when the rhs is unsigned (and needs
extension).
- This fixes cfrac.
- <rdr://6115726>
llvm-svn: 54392
scimark2 on Darwin.
- Added Sema support for asm-label on variables, which I forgot before.
- Update CodeGen to use GlobalDeclMap to determine if static Decls
require emission (instead of LLVM module name lookup). Important
since the Decl name and the LLVM module name can differ.
- <rdar://problem/6116729>
llvm-svn: 54388
having multiple bindings from all the possible decls which
conceptually map to the same global).
- This eliminates CodeGen depending on the LLVM module for name
lookup.
- This also eliminates the need for ReplaceMapValuesWith (hurrah).
- This handles lookups for FunctionDecls correctly in the presence of
aliases, this was previously broken.
- WIP: Can still clean up & unify variable and function emission.
llvm-svn: 54382
Updated a few clients of DeclStmt::getNextDeclarator() to use decl_iterator instead. Will update other clients after additional testing.
llvm-svn: 54368
- ActOnDeclarator now takes an additional parameter which is the
AsmLabel if used. Its unfortunate that this bubbles up this high,
but we cannot just lump it in as an attribute without mistakenly
*accepting* it as an attribute.
- The actual asm-label itself is, however, encoded as an AsmLabelAttr
on the FunctionDecl.
- Slightly improved parser error recovery on malformed asm-labels.
- CodeGen support still missing...
llvm-svn: 54339
- Like EXTENSION but always generates a warning (even without
-pedantic).
- Updated ptr -> int, int -> ptr, and incompatible cast warnings to
be EXTWARN.
- Other EXTENSION level diagnostics should be audited for upgrade.
- Updated several test cases to fix code which produced unanticipated
warnings.
llvm-svn: 54335
When results go to a auto-generated dir in /tmp, don't use randomized file names. Just output /tmp/scan-build-DATE-counter, where counter is an auto-incremented counter for runs produced that day.
llvm-svn: 54325
- Follows emission scheme used by llvm-gcc, i.e. invent an id for
each label whose address is taken and replace each indirect goto by
a switch to each possible target.
- Currently we emit a switch for each indirect goto instead of
merging them as llvm-gcc does.
llvm-svn: 54318
move getAsArrayType into ASTContext instead of being a method on type.
This is required because getAsArrayType(const AT), where AT is a typedef
for "int[10]" needs to return ArrayType(const int, 10).
Fixing this greatly simplifies getArrayDecayedType, which is a good sign.
llvm-svn: 54317
- There is an miscompilation issue remaining due to a poor
interaction between the delayed emission of static functions and
the emission of constructors, but that already existed prior to
this change.
