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

2009-03-29Alpha always requires global relocations to be r/w regardless of PIC.Anton Korobeynikov

2009-03-25CodeGen still defaults to non-verbose asm, but llc now overrides it and ↵Evan Cheng
default to verbose. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@67668 91177308-0d34-0410-b5e6-96231b3b80d8
2009-03-19Add support to tablegen for naming the nodes themselves, not just the operands, Nate Begeman
in selectiondag patterns. This is required for the upcoming shuffle_vector rewrite, and as it turns out, cleans up a hack in the Alpha instruction info. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@67286 91177308-0d34-0410-b5e6-96231b3b80d8
2009-03-11It makes no sense to have a ODR version of commonDuncan Sands
linkage, so remove it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@66690 91177308-0d34-0410-b5e6-96231b3b80d8
2009-03-07Introduce new linkage types linkonce_odr, weak_odr, common_odrDuncan Sands
and extern_weak_odr. These are the same as the non-odr versions, except that they indicate that the global will only be overridden by an *equivalent* global. In C, a function with weak linkage can be overridden by a function which behaves completely differently. This means that IP passes have to skip weak functions, since any deductions made from the function definition might be wrong, since the definition could be replaced by something completely different at link time. This is not allowed in C++, thanks to the ODR (One-Definition-Rule): if a function is replaced by another at link-time, then the new function must be the same as the original function. If a language knows that a function or other global can only be overridden by an equivalent global, it can give it the weak_odr linkage type, and the optimizers will understand that it is alright to make deductions based on the function body. The code generators on the other hand map weak and weak_odr linkage to the same thing. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@66339 91177308-0d34-0410-b5e6-96231b3b80d8
2009-02-24Overhaul my earlier submission due to feedback. It's a large patch, but most ofBill Wendling
them are generic changes. - Use the "fast" flag that's already being passed into the asm printers instead of shoving it into the DwarfWriter. - Instead of calling "MI->getParent()->getParent()" for every MI, set the machine function when calling "runOnMachineFunction" in the asm printers. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@65379 91177308-0d34-0410-b5e6-96231b3b80d8

2009-02-09Turns out AnalyzeBranch can modify the mbb being analyzed. This is a nastyEvan Cheng
suprise to some callers, e.g. register coalescer. For now, add an parameter that tells AnalyzeBranch whether it's safe to modify the mbb. A better solution is out there, but I don't have time to deal with it right now. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@64124 91177308-0d34-0410-b5e6-96231b3b80d8

2009-02-07Get rid of the last non-DebugLoc versions of getNode!Dale Johannesen
Many targets build placeholder nodes for special operands, e.g. GlobalBaseReg on X86 and PPC for the PIC base. There's no sensible way to associate debug info with these. I've left them built with getNode calls with explicit DebugLoc::getUnknownLoc operands. I'm not too happy about this but don't see a good improvement; I considered adding a getPseudoOperand or something, but it seems to me that'll just make it harder to read. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@63992 91177308-0d34-0410-b5e6-96231b3b80d8

2009-01-15Move a few containers out of ScheduleDAGInstrs::BuildSchedGraphDan Gohman
and into the ScheduleDAGInstrs class, so that they don't get destructed and re-constructed for each block. This fixes a compile-time hot spot in the post-pass scheduler. To help facilitate this, tidy and do some minor reorganization in the scheduler constructor functions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@62275 91177308-0d34-0410-b5e6-96231b3b80d8

2009-01-01Fix PR3274: when promoting the condition of a BRCOND node,Duncan Sands
promote from i1 all the way up to the canonical SetCC type. In order to discover an appropriate type to use, pass MVT::Other to getSetCCResultType. In order to be able to do this, change getSetCCResultType to take a type as an argument, not a value (this is also more logical). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@61542 91177308-0d34-0410-b5e6-96231b3b80d8

2008-12-01Change the interface to the type legalization methodDuncan Sands
ReplaceNodeResults: rather than returning a node which must have the same number of results as the original node (which means mucking around with MERGE_VALUES, and which is also easy to get wrong since SelectionDAG folding may mean you don't get the node you expect), return the results in a vector. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@60348 91177308-0d34-0410-b5e6-96231b3b80d8

2008-11-23Rename SetCCResultContents to BooleanContents. InDuncan Sands

2008-11-15Adds extern "C" ints to the .cpp files that use RegisterTarget, asOscar Fuentes
well as 2 files that use "Registrator"s.
