* Preserve address space of forward-referenced global variables in the LL parserJustin Holewinski2012-11-16
| | | | | | | | | | | | Before, the parser would assert on the following code: @a2 = global i8 addrspace(1)* @a @a = addrspace(1) global i8 0 because the type of @a was "i8*" instead of "i8 addrspace(1)*" when parsing the initializer for @a2. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@168197 91177308-0d34-0410-b5e6-96231b3b80d8
* Relax the restrictions on vector of pointer types, and vector getelementptr.Duncan Sands2012-11-13
| | | | | | | | | | | | | | | | Previously in a vector of pointers, the pointer couldn't be any pointer type, it had to be a pointer to an integer or floating point type. This is a hassle for dragonegg because the GCC vectorizer happily produces vectors of pointers where the pointer is a pointer to a struct or whatever. Vector getelementptr was restricted to just one index, but now that vectors of pointers can have any pointer type it is more natural to allow arbitrary vector getelementptrs. There is however the issue of struct GEPs, where if each lane chose different struct fields then from that point on each lane will be working down into unrelated types. This seems like too much pain for too little gain, so when you have a vector struct index all the elements are required to be the same. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@167828 91177308-0d34-0410-b5e6-96231b3b80d8

* Fix the remaining TCL-style quotes found in the testsuite. This isChandler Carruth2012-07-02
| | | | | | | | | | | | | | | | | another mechanical change accomplished though the power of terrible Perl scripts. I have manually switched some "s to 's to make escaping simpler. While I started this to fix tests that aren't run in all configurations, the massive number of tests is due to a really frustrating fragility of our testing infrastructure: things like 'grep -v', 'not grep', and 'expected failures' can mask broken tests all too easily. Essentially, I'm deeply disturbed that I can change the testsuite so radically without causing any change in results for most platforms. =/ git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@159547 91177308-0d34-0410-b5e6-96231b3b80d8

* Convert all tests using TCL-style quoting to use shell-style quoting.Chandler Carruth2012-07-02
| | | | | | | | | | | | | | | | | | | | | | | | This was done through the aid of a terrible Perl creation. I will not paste any of the horrors here. Suffice to say, it require multiple staged rounds of replacements, state carried between, and a few nested-construct-parsing hacks that I'm not proud of. It happens, by luck, to be able to deal with all the TCL-quoting patterns in evidence in the LLVM test suite. If anyone is maintaining large out-of-tree test trees, feel free to poke me and I'll send you the steps I used to convert things, as well as answer any painful questions etc. IRC works best for this type of thing I find. Once converted, switch the LLVM lit config to use ShTests the same as Clang. In addition to being able to delete large amounts of Python code from 'lit', this will also simplify the entire test suite and some of lit's architecture. Finally, the test suite runs 33% faster on Linux now. ;] For my 16-hardware-thread (2x 4-core xeon e5520): 36s -> 24s git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@159525 91177308-0d34-0410-b5e6-96231b3b80d8
* Make tests which first provide a negative assertion via 'not', thenChandler Carruth2012-07-02
| | | | | | | | | | | | | | | | a pipeline, and then a positive assertion via grep, use two RUN lines instead. Supporting these complex ideas of 'success' and 'failure' across multiple stages of a pipeline is brittle in the shell world, and would block switching to ShTest format; it only worked due to contrivances introduced by the TclTest format. Writing this as two separate RUN lines seems clearer in any event. This is another step toward completely removing TclTests from lit. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@159524 91177308-0d34-0410-b5e6-96231b3b80d8
* Extend the IL for selecting TLS models (PR9788)Hans Wennborg2012-06-23
| | | | | | | | | | | | | | | This allows the user/front-end to specify a model that is better than what LLVM would choose by default. For example, a variable might be declared as @x = thread_local(initialexec) global i32 42 if it will not be used in a shared library that is dlopen'ed. If the specified model isn't supported by the target, or if LLVM can make a better choice, a different model may be used. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@159077 91177308-0d34-0410-b5e6-96231b3b80d8

* Add an explicit test of the auto-upgrade functionality for the newChandler Carruth2011-12-12
| | | | | | | | | | | | | 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

* Split the init.trampoline intrinsic, which currently combines GCC'sDuncan Sands2011-09-06
| | | | | | | | | | | | | | | | | | | | | 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

* Land the long talked about "type system rewrite" patch. ThisChris Lattner2011-07-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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

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

| | | | | | | | | | | | | | | | | | | 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
