2011-12-12Add an explicit test of the auto-upgrade functionality for the newChandler Carruth
intrinsic syntax. Now that this is explicitly covered, I plan to upgrade the existing test suite to use an explicit immediate. Note that I plan to specify 'true' in most places rather than the auto-upgraded value as that is the far more common value to end up here as that is the value coming from GCC's builtins. The only place I'm likely to put a 'false' in is when testing x86 which actually has different instructions for the two variants. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@146369 91177308-0d34-0410-b5e6-96231b3b80d8
2011-11-27remove autoupgrade support for old forms of llvm.prefetch and the oldChris Lattner

by David Meyer on llvmdev. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@140040 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-06Split the init.trampoline intrinsic, which currently combines GCC'sDuncan Sands
init.trampoline and adjust.trampoline intrinsics, into two intrinsics like in GCC. While having one combined intrinsic is tempting, it is not natural because typically the trampoline initialization needs to be done in one function, and the result of adjust trampoline is needed in a different (nested) function. To get around this llvm-gcc hacks the nested function lowering code to insert an additional parent variable holding the adjust.trampoline result that can be accessed from the child function. Dragonegg doesn't have the luxury of tweaking GCC code, so it stored the result of adjust.trampoline in the memory GCC set aside for the trampoline itself (this is always available in the child function), and set up some new memory (using an alloca) to hold the trampoline. Unfortunately this breaks Go which allocates trampoline memory on the heap and wants to use it even after the parent has exited (!). Rather than doing even more hacks to get Go working, it seemed best to just use two intrinsics like in GCC. Patch mostly by Sanjoy Das. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@139140 91177308-0d34-0410-b5e6-96231b3b80d8

2011-08-12Move "atomic" and "volatile" designations on instructions after the opcodeEli Friedman
of the instruction. Note that this change affects the existing non-atomic load and store instructions; the parser now accepts both forms, and the change is noted in the release notes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@137527 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-09Land the long talked about "type system rewrite" patch. ThisChris Lattner
patch brings numerous advantages to LLVM. One way to look at it is through diffstat: 109 files changed, 3005 insertions(+), 5906 deletions(-) Removing almost 3K lines of code is a good thing. Other advantages include: 1. Value::getType() is a simple load that can be CSE'd, not a mutating union-find operation. 2. Types a uniqued and never move once created, defining away PATypeHolder. 3. Structs can be "named" now, and their name is part of the identity that uniques them. This means that the compiler doesn't merge them structurally which makes the IR much less confusing. 4. Now that there is no way to get a cycle in a type graph without a named struct type, "upreferences" go away. 5. Type refinement is completely gone, which should make LTO much MUCH faster in some common cases with C++ code. 6. Types are now generally immutable, so we can use "Type *" instead "const Type *" everywhere. Downsides of this patch are that it removes some functions from the C API, so people using those will have to upgrade to (not yet added) new API. "LLVM 3.0" is the right time to do this. There are still some cleanups pending after this, this patch is large enough as-is. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@134829 91177308-0d34-0410-b5e6-96231b3b80d8

2011-05-18Tighten up checking of the validity of casts. (1) The IR parser wouldDuncan Sands
happily accept things like "sext <2 x i32> to <999 x i64>". It would also accept "sext <2 x i32> to i64", though the verifier would catch that later. Fixed by having castIsValid check that vector lengths match except when doing a bitcast. (2) When creating a cast instruction, check that the cast is valid (this was already done when creating constexpr casts). While there, replace getScalarSizeInBits (used to allow more vector casts) with getPrimitiveSizeInBits in getCastOpcode and isCastable since vector to vector casts are now handled explicitly by passing to the element types; i.e. this bit should result in no functional change. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@131532 91177308-0d34-0410-b5e6-96231b3b80d8

2011-01-08First step in fixing PR8927:Rafael Espindola
Add a unnamed_addr bit to global variables and functions. This will be used to indicate that the address is not significant and therefore the constant or function can be merged with others. If an optimization pass can show that an address is not used, it can set this. Examples of things that can have this set by the FE are globals created to hold string literals and C++ constructors. Adding unnamed_addr to a non-const global should have no effect unless an optimization can transform that global into a constant. Aliases are not allowed to have unnamed_addr since I couldn't figure out any use for it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@123063 91177308-0d34-0410-b5e6-96231b3b80d8

2010-09-30Massive rewrite of MMX: Dale Johannesen
The x86_mmx type is used for MMX intrinsics, parameters and return values where these use MMX registers, and is also supported in load, store, and bitcast. Only the above operations generate MMX instructions, and optimizations do not operate on or produce MMX intrinsics. MMX-sized vectors <2 x i32> etc. are lowered to XMM or split into smaller pieces. Optimizations may occur on these forms and the result casted back to x86_mmx, provided the result feeds into a previous existing x86_mmx operation. The point of all this is prevent optimizations from introducing MMX operations, which is unsafe due to the EMMS problem. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@115243 91177308-0d34-0410-b5e6-96231b3b80d8
