e733472221 Make ConstantInt not care about sign any more. To ensure the AsmParser can 
still check the validity of signed values an overload to isValueValidForType
was added to allow passing in an int64_t to check.

bb65ebf9a1 Replace inferred getCast(V,Ty) calls with more strict variants. 
Rename getZeroExtend and getSignExtend to getZExt and getSExt to match
the the casting mnemonics in the rest of LLVM.

to the createIntegerCast and createFPCast for CastInst instructions.

e51700983a For PR950: 
Remove the getMaxValue and getMinValue functions from ConstantIntegral.
They don't make sense for a signless type. Also, for isMaxValue and
isMinValue, have the caller provided the signedness rather than obtaining
it from the constant's type.

c4dacf2455 Take a baby step towards getting rid of inferred casts. Provide methods on 
CastInst and ConstantExpr that allow the signedness to be explicitly passed
in and reliance on signedness removed from getCastOpcode. These are
temporary measures useful during the conversion of inferred casts.

6c38f0bb07 For PR950: 
The long awaited CAST patch. This introduces 12 new instructions into LLVM
to replace the cast instruction. Corresponding changes throughout LLVM are
provided. This passes llvm-test, llvm/test, and SPEC CPUINT2000 with the
exception of 175.vpr which fails only on a slight floating point output
difference.

AShr (Arithmetic) and LShr (Logical). The Shr instructions now are not

in favor of just using ConstantInt.

82ebabafde Provide a simpler interface for getting a ConstantArray from a character 
string. Instead of specifying the length, just specify whether the user
wants a terminating null or not. The default is "true" to retain the same
behavior as previously provided by this function.

llvm-svn: 28562
 2006-05-30 18:15:07 +00:00
Reid Spencer
6f61453ff8 Adjust the interface to ConstantArray::get. The previous 
implementation always added a null byte to the end of the string. It turns
out that this is not always wanted. By adding a length parameter we preserve
this behavior when length==0 (default value) but also allow other lengths
(not null terminated) to be created.
