2010-10-19Get rid of static constructors for pass registration. Instead, every pass ↵Owen Anderson
exposes an initializeMyPassFunction(), which must be called in the pass's constructor. This function uses static dependency declarations to recursively initialize the pass's dependencies. Clients that only create passes through the createFooPass() APIs will require no changes. Clients that want to use the CommandLine options for passes will need to manually call the appropriate initialization functions in PassInitialization.h before parsing commandline arguments. I have tested this with all standard configurations of clang and llvm-gcc on Darwin. It is possible that there are problems with the static dependencies that will only be visible with non-standard options. If you encounter any crash in pass registration/creation, please send the testcase to me directly. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@116820 91177308-0d34-0410-b5e6-96231b3b80d8

2010-08-11Don't use unsigned char for alignments in TargetData. There aren'tDan Gohman
that many of these things, so the memory savings isn't significant, and there are now situations where there can be alignments greater than 128. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@110836 91177308-0d34-0410-b5e6-96231b3b80d8

2010-04-23Change TargetData's algorithm for computing defualt vector typeDan Gohman
alignment to match what's used in clang and GCC for __alignof, rather than trying to guess what Legalize is going to be doing. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@102206 91177308-0d34-0410-b5e6-96231b3b80d8

2010-04-02Revert the recent alignment changes. They're broken for -Os because,Dan Gohman
in particular, they end up aligning strings at 16-byte boundaries, and there's no way for GlobalOpt to check OptForSize. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@100172 91177308-0d34-0410-b5e6-96231b3b80d8

2010-02-25Revert r97064. Duncan pointed out that bitcasts are defined inDan Gohman
terms of store and load, which means bitcasting between scalar integer and vector has endian-specific results, which undermines this whole approach. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@97137 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-24Make getTypeSizeInBits work correctly for array types; it should returnDan Gohman
the number of value bits, not the number of bits of allocation for in-memory storage. Make getTypeStoreSize and getTypeAllocSize work consistently for arrays and vectors. Fix several places in CodeGen which compute offsets into in-memory vectors to use TargetData information. This fixes PR1784. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@97064 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-16There are two ways of checking for a given type, for example isa<PointerType>(T)Duncan Sands

2010-01-25add a method to get the alignment of an integer type even Chris Lattner

Patch by Howard Hinnant! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@90365 91177308-0d34-0410-b5e6-96231b3b80d8
2009-12-03This initial code is meant to convert TargetData to use an AbstractTypesUser soBill Wendling
that it doesn't have dangling pointers when abstract types are resolved. This modifies it somewhat to address comments: making the "StructLayoutMap" an anonymous structure, calling "removeAbstractTypeUser" when appropriate, and adding asserts where helpful. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@90362 91177308-0d34-0410-b5e6-96231b3b80d8
2009-11-18The llvm-gcc front-end and the pass manager use two separate TargetData objects.Bill Wendling
This is probably not confined to *just* these two things. Anyway, the llvm-gcc front-end may look up the structure layout information for an abstract type. That information will be stored into a table with the FE's TD. Instruction combine can come along and also ask for information on that abstract type, but for a separate TD (the one associated with the pass manager). After the type is refined, the old structure layout information in the pass manager's TD file is out of date. If a new type is allocated in the same space as the old-unrefined type, then the structure type information in the pass manager's TD file will be wrong, but won't know it. Fix this by making the TD's structure type information an abstract type user. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@89176 91177308-0d34-0410-b5e6-96231b3b80d8
2009-11-08Make TargetData::getStringRepresentation spit out native integer types,Chris Lattner
this gives llvm-gcc generated modules the right data. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@86435 91177308-0d34-0410-b5e6-96231b3b80d8
2009-11-07add the ability for TargetData to return information about legal integerChris Lattner
datatypes on a given CPU. This is intended to allow instcombine and other transformations to avoid converting big sequences of operations to an inconvenient width, and will help clean up after SRoA. See also "Adding legal integer sizes to TargetData" on Feb 1, 2009 on llvmdev, and PR3451. Comments welcome. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@86370 91177308-0d34-0410-b5e6-96231b3b80d8

2009-07-14llvm_unreachable->llvm_unreachable(0), LLVM_UNREACHABLE->llvm_unreachable.Torok Edwin
This adds location info for all llvm_unreachable calls (which is a macro now) in !NDEBUG builds. In NDEBUG builds location info and the message is off (it only prints "UREACHABLE executed"). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@75640 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-11assert(0) -> LLVM_UNREACHABLE.Torok Edwin
Make llvm_unreachable take an optional string, thus moving the cerr<< out of line. LLVM_UNREACHABLE is now a simple wrapper that makes the message go away for NDEBUG builds. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@75379 91177308-0d34-0410-b5e6-96231b3b80d8
