John Criswell 764f2c03bc Changed from PARALLEL_DIRS to DIRS since we're only building one directory. 
Thanks Reid.

Reid Spencer df1f19a8ef Change the interface to SCEVExpander::InsertCastOfTo to take a cast opcode 
so the decision of which opcode to use is pushed upward to the caller.
Adjust the callers to pass the expected opcode.

Reid Spencer 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.

Chris Lattner 49b090ed61 teach scev to analyze X*4|1 like X*4+c. This allows us to produce:

Chris Lattner edcc8c2f8b Remove the 'printname' argument to WriteAsOperand. It is always true, and 
passing false would make the asmprinter fail anyway.

Reid Spencer 0646eb415d Finally get the casting right in this file. Also, remove some unnecessary 
casting because sdiv doesn't require operand signs to match any more.

Bill Wendling afd54eb8b6 Replacing std::iostreams with llvm iostreams. Some of these changes involve 
adding a temporary wrapper around the ostream to make it friendly to
functions expecting an LLVM stream. This should be fixed in the future.

llvm-svn: 31990
 2006-11-29 00:19:40 +00:00

Reid Spencer 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.

llvm-svn: 31931
 2006-11-27 01:05:10 +00:00
Reid Spencer d9436b6837 For PR950: 
First in a series of patches to convert SetCondInst into ICmpInst and
FCmpInst using only two opcodes and having the instructions contain their
predicate value. Nothing uses these classes yet. More patches to follow.

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

Chris Lattner ea2abe2384 Fix BasicAA/2006-11-03-BasicAAVectorCrash.ll by handling out-of-range 
vector accesses like we handle out-of-range array accesses.

llvm-svn: 31427
 2006-11-03 21:58:48 +00:00
Andrew Lenharth 01a4a5d07e Split the External and Intrinsic handling into seperate functions. This 
improves readability of the call handling code significantly, as well as
makes it clear which parts are hacky (externals) and which parts are good
(call handling).

No functionality change.

Reid Spencer de46e48420 For PR786: 
Turn on -Wunused and -Wno-unused-parameter. Clean up most of the resulting
fall out by removing unused variables. Remaining warnings have to do with
unused functions (I didn't want to delete code without review) and unused
variables in generated code. Maintainers should clean up the remaining
issues when they see them. All changes pass DejaGnu tests and Olden.
