Sanjiv Gupta 639f2d92f8 Don't use static globals for params as it confuses the optimzer that their values are never being used in the function.

declaration. Reject it.

Chris Lattner e09ad90882 don't set the name of a call instruction to "call" in release-asserts 
build.  This shaves another 3% off.

Chris Lattner 47640221da fix CreateTempAlloca to not set a name on the alloca for temporaries 
in release-assert builds.  For automatic variables, explicitly set
a name with setName that does not make a temporary std::string.

This speeds up -emit-llvm-only -disable-free on PR3810 by 4.6%

Daniel Dunbar f804897ee9 Don't mangle names of local variables. 
- For one thing, this adds unneeded overhead; for another, this
   routine can be used to emit unnamed decls which we shouldn't try to
   mangle.

Mike Stump 97d01d50d9 Improved ABI compliance for __block variables. No testcases yet as we 
still give an unsupported error for them due to the fact this is a
work in progress.

Eli Friedman 34ef305759 Last part of PR3254: use the same alignment computation in Sema and 
CodeGen.  I'm not sure whether this actually makes any visible 
difference, but it's better to be consistent anyway.

Douglas Gregor 5f361c9f1e Address Chris's comments regarding C++ name mangling. 
llvm-svn: 64984
 2009-02-18 23:53:56 +00:00
Daniel Dunbar 38ad1e6138 Change EmitConstantExpr to allow failure. 
IRgen no longer relies on isConstantInitializer, instead we just try
to emit the constant. If that fails then in C we emit an error
unsupported (this occurs when Sema accepted something that it doesn't
know how to fold, and IRgen doesn't know how to emit) and in C++ we
emit a guarded initializer.

This ends up handling a few more cases, because IRgen was actually
able to emit some of the constants Sema accepts but can't Evaluate().
For example, PR3398.

Anders Carlsson 63784f4e5e Add CodeGen support for the nodebug attribute.

Douglas Gregor 5fec5b0495 Add basic support for C++ name mangling according to the Itanium C++ 
ABI to the CodeGen library. Since C++ code-generation is so
incomplete, we can't exercise much of this mangling code. However, a
few smoke tests show that it's doing the same thing as GCC. When C++
codegen matures, we'll extend the ABI tester to verify name-mangling
as well, and complete the implementation here.

At this point, the major client of name mangling is in the uses of the
new "overloadable" attribute in C, which allows overloading. Any
"overloadable" function in C (or in an extern "C" block in C++) will
be mangled the same way that the corresponding C++ function would be
mangled.

Sanjiv Gupta e99ad00fd2 Function parameters for PIC16 are like local variables. So use the keyword ".auto." to mangle their names. The working of PIC16AsmPrinter relies on that keyword currently.

Sanjiv Gupta c1b58d40e6 Targets that don't have stack use global address space for parameters. 
Specify external linkage for such globals so that llvm optimizer do
not assume there values initialized as zero.

 2009-02-03 18:07:49 +00:00
Eli Friedman 7139af42ce Rename Expr::isConstantExpr to Expr::isConstantInitializer; this more 
accurately states what the function is trying to do and how it is 
different from Expr::isEvaluatable.  Also get rid of a parameter that is both 
unused and inaccurate.

llvm-svn: 62951

Chris Lattner 8a42586c54 more SourceLocation lexicon change: instead of referring to the 
"logical" location, refer to the "instantiation" location.

Eli Friedman f4084708cd Make VLAs usable, and make basic usage work correctly. Also, add a 
simple test that actually does VLA codegen.

Note that despite the fact that the alloca isn't in the entry block, it 
should dominate all uses; this is guaranteed by the restrictions on goto 
into VLA scope in C99.

Anders Carlsson 8a01b79274 Change EmitVLASize to take a QualType that must be a variably modified type. 
Emit the size even if the declared type is a variably modified type. This lets us handle

  int (*a)[n];
  
  printf("size: %d\n", sizeof(*a));
}
