2012-10-09Create enums for the different attributes.Bill Wendling
We use the enums to query whether an Attributes object has that attribute. The opaque layer is responsible for knowing where that specific attribute is stored. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@165488 91177308-0d34-0410-b5e6-96231b3b80d8

2012-10-08Begin the transition to using the AttributesImpl object for the Attributes ivar.Bill Wendling
Start using the AttributesImpl object to hold the value of the attributes. All queries go through the interfaces now. This has one unfortunate consequence. I needed to move the AttributesImpl.h file into include/llvm. But this is only temporary! Otherwise, the changes needed to support this would be too large. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@165433 91177308-0d34-0410-b5e6-96231b3b80d8
2012-10-07Move more methods out-of-line. This is in preparation for changing the internalBill Wendling
contents of the Attributes class over to an AttributesImpl. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@165373 91177308-0d34-0410-b5e6-96231b3b80d8
2012-10-05Move methods out-of-line.Bill Wendling
The internal representation of the Attributes class will be opaque. All of the query methods will need to query the opaque class. Therefore, these methods need to be out-of-line. No functionality change intended. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@165305 91177308-0d34-0410-b5e6-96231b3b80d8
2012-09-26Initial commit for the AttributesImpl class.Bill Wendling
This opaque class will contain all of the attributes. All attribute queries will go through this object. This object will also be uniqued in the LLVMContext. Currently not used, so no implementation change. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@164722 91177308-0d34-0410-b5e6-96231b3b80d8

2012-09-04[ms-inline asm] Remove the Inline Asm Non-Standard Dialect attribute. ThisChad Rosier
implementation does not co-exist well with how the sideeffect and alignstack attributes are handled. The reverts r161641. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@163174 91177308-0d34-0410-b5e6-96231b3b80d8
2012-08-10[ms-inline asm] Add a new Inline Asm Non-Standard Dialect attribute.Chad Rosier
This new attribute is intended to be used by the backend to determine how the inline asm string should be parsed/printed. This patch adds the ia_nsdialect attribute and also adds a test case to ensure the IR is correctly parsed, but there is no functional change at this time. The standard dialect is assumed to be AT&T. Therefore, this attribute should only be added to MS-style inline assembly statements, which use the Intel dialect. If we ever support more dialects we'll need to add additional state to the attribute. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@161641 91177308-0d34-0410-b5e6-96231b3b80d8

2012-01-20Extend Attributes to 64 bitsKostya Serebryany
Problem: LLVM needs more function attributes than currently available (32 bits). One such proposed attribute is "address_safety", which shows that a function is being checked for address safety (by AddressSanitizer, SAFECode, etc). Solution: - extend the Attributes from 32 bits to 64-bits - wrap the object into a class so that unsigned is never erroneously used instead - change "unsigned" to "Attributes" throughout the code, including one place in clang. - the class has no "operator uint64 ()", but it has "uint64_t Raw() " to support packing/unpacking. - the class has "safe operator bool()" to support the common idiom: if (Attributes attr = getAttrs()) useAttrs(attr); - The CTOR from uint64_t is marked explicit, so I had to add a few explicit CTOR calls - Add the new attribute "address_safety". Doing it in the same commit to check that attributes beyond first 32 bits actually work. - Some of the functions from the Attribute namespace are worth moving inside the class, but I'd prefer to have it as a separate commit. Tested: "make check" on Linux (32-bit and 64-bit) and Mac (10.6) built/run spec CPU 2006 on Linux with clang -O2. This change will break clang build in lib/CodeGen/CGCall.cpp. The following patch will fix it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@148553 91177308-0d34-0410-b5e6-96231b3b80d8

2011-06-15Add a new function attribute, nonlazybind, which inhibits lazy-loadingJohn McCall
optimizations when emitting calls to the function; instead those calls may use faster relocations which require the function to be immediately resolved upon loading the dynamic object featuring the call. This is useful when it is known that the function will be called frequently and pervasively and therefore there is no merit in delaying binding of the function. Currently only implemented for x86-64, where it turns into a call through the global offset table. Patch by Dan Gohman, who assures me that he's going to add LangRef documentation for this once it's committed. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@133080 91177308-0d34-0410-b5e6-96231b3b80d8

2010-11-09Fix PR8441, a race condition in the static attributes list. While the ↵Owen Anderson

2010-02-12Add a new function attribute, 'alignstack'. It will indicate (when the backendsCharles Davis
implement support for it) that the stack should be forcibly realigned in the prologue (and the process reversed in the epilogue). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@95945 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-06Reintroduce the InlineHint function attribute.Jakob Stoklund Olesen
This time it's for real! I am going to hook this up in the frontends as well. The inliner has some experimental heuristics for dealing with the inline hint. When given a -respect-inlinehint option, functions marked with the inline keyword are given a threshold just above the default for -O3. We need some experiments to determine if that is the right thing to do. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@95466 91177308-0d34-0410-b5e6-96231b3b80d8
