2009-06-04Fix an erroneous check for isFNeg; the FNeg case is handledDan Gohman
a few lines later on. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@72904 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-04Split the Add, Sub, and Mul instruction opcodes into separateDan Gohman
integer and floating-point opcodes, introducing FAdd, FSub, and FMul. For now, the AsmParser, BitcodeReader, and IRBuilder all preserve backwards compatability, and the Core LLVM APIs preserve backwards compatibility for IR producers. Most front-ends won't need to change immediately. This implements the first step of the plan outlined here: http://nondot.org/sabre/LLVMNotes/IntegerOverflow.txt git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@72897 91177308-0d34-0410-b5e6-96231b3b80d8

2009-05-09Rename PaddedSize to AllocSize, in the hope that thisDuncan Sands

2009-04-29Instead of passing in an unsigned value for the optimization level, use an enum,Bill Wendling
which better identifies what the optimization is doing. And is more flexible for future uses. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@70440 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-29Second attempt:Bill Wendling
Massive check in. This changes the "-fast" flag to "-O#" in llc. If you want to use the old behavior, the flag is -O0. This change allows for finer-grained control over which optimizations are run at different -O levels. Most of this work was pretty mechanical. The majority of the fixes came from verifying that a "fast" variable wasn't used anymore. The JIT still uses a "Fast" flag. I'll change the JIT with a follow-up patch. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@70343 91177308-0d34-0410-b5e6-96231b3b80d8

2009-03-23Fix internal representation of fp80 to be theDale Johannesen
same as a normal i80 {low64, high16} rather than its own {high64, low16}. A depressing number of places know about this; I think I got them all.

well as 2 files that use "Registrator"s.

2008-10-14Fix command-line option printing to print two spaces where needed,Dan Gohman
instead of requiring all "short description" strings to begin with two spaces.

2008-09-25 Large mechanical patch.Devang Patel
s/ParamAttr/Attribute/g s/PAList/AttrList/g s/FnAttributeWithIndex/AttributeWithIndex/g s/FnAttr/Attribute/g This sets the stage - to implement function notes as function attributes and - to distinguish between function attributes and return value attributes.

2008-08-17Rename some GC classes so that their roll will hopefully be clearer.Gordon Henriksen
In particular, Collector was confusing to implementors. Several thought that this compile-time class was the place to implement their runtime GC heap. Of course, it doesn't even exist at runtime. Specifically, the renames are: Collector -> GCStrategy CollectorMetadata -> GCFunctionInfo CollectorModuleMetadata -> GCModuleInfo CollectorRegistry -> GCRegistry Function::getCollector -> getGC (setGC, hasGC, clearGC) Several accessors and nested types have also been renamed to be consistent. These changes should be obvious. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@54899 91177308-0d34-0410-b5e6-96231b3b80d8

2008-07-23Enable first-class aggregates support.Dan Gohman
Remove the GetResultInst instruction. It is still accepted in LLVM assembly and bitcode, where it is now auto-upgraded to ExtractValueInst. Also, remove support for return instructions with multiple values. These are auto-upgraded to use InsertValueInst instructions. The IRBuilder still accepts multiple-value returns, and auto-upgrades them to InsertValueInst instructions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@53941 91177308-0d34-0410-b5e6-96231b3b80d8

ability to handle indirect input operands. This fixes PR2407. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@51952 91177308-0d34-0410-b5e6-96231b3b80d8
2008-06-02Implement CBE support for first-class structs and array values,Dan Gohman
and insertvalue and extractvalue instructions. First-class array values are not trivial because C doesn't support them. The approach I took here is to wrap all arrays in structs. Feedback is welcome. The 2007-01-15-NamedArrayType.ll test needed to be modified because it has a "not grep" for a string that now exists, because array types now have associated struct types, and those struct types have names. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@51881 91177308-0d34-0410-b5e6-96231b3b80d8
2008-05-31Fix the CBE's handling of instructions whose result is an i1. Previously,Chris Lattner
we did not truncate the value down to i1 with (x&1). This caused a problem when the computation of x was nontrivial, for example, "add i1 1, 1" would return 2 instead of 0. This makes the testcase compile into: ... llvm_cbe_t = (((llvm_cbe_r == 0u) + (llvm_cbe_r == 0u))&1); llvm_cbe_u = (((unsigned int )(bool )llvm_cbe_t)); ... instead of: ... llvm_cbe_t = ((llvm_cbe_r == 0u) + (llvm_cbe_r == 0u)); llvm_cbe_u = (((unsigned int )(bool )llvm_cbe_t)); ... This fixes a miscompilation of mediabench/adpcm/rawdaudio/rawdaudio and 403.gcc with the CBE, regressions from LLVM 2.2. Tanya, please pull this into the release branch. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@51813 91177308-0d34-0410-b5e6-96231b3b80d8

2008-05-14Add CommonLinkage; currently tentative definitionsDale Johannesen
are represented as "weak", but there are subtle differences in some cases on Darwin, so we need both. The intent is that "common" will behave identically to "weak" unless somebody changes their target to do something else.

2008-03-12Reimplement the parameter attributes support, phase #1. hilights:Chris Lattner
1. There is now a "PAListPtr" class, which is a smart pointer around the underlying uniqued parameter attribute list object, and manages its refcount. It is now impossible to mess up the refcount. 2. PAListPtr is now the main interface to the underlying object, and the underlying object is now completely opaque. 3. Implementation details like SmallVector and FoldingSet are now no longer part of the interface. 4. You can create a PAListPtr with an arbitrary sequence of ParamAttrsWithIndex's, no need to make a SmallVector of a specific size (you can just use an array or scalar or vector if you wish). 5. All the client code that had to check for a null pointer before dereferencing the pointer is simplified to just access the PAListPtr directly. 6. The interfaces for adding attrs to a list and removing them is a bit simpler. Phase #2 will rename some stuff (e.g. PAListPtr) and do other less invasive changes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@48289 91177308-0d34-0410-b5e6-96231b3b80d8
