2012-08-17Change the `linker_private_weak_def_auto' linkage to `linkonce_odr_auto_hide' toBill Wendling
make it more consistent with its intended semantics. The `linker_private_weak_def_auto' linkage type was meant to automatically hide globals which never had their addresses taken. It has nothing to do with the `linker_private' linkage type, which outputs the symbols with a `l' (ell) prefix among other things. The intended semantic is more like the `linkonce_odr' linkage type. Change the name of the linkage type to `linkonce_odr_auto_hide'. And therefore changing the semantics so that it produces the correct output for the linker. Note: The old linkage name `linker_private_weak_def_auto' will still parse but is not a synonym for `linkonce_odr_auto_hide'. This should be removed in 4.0. <rdar://problem/11754934> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@162114 91177308-0d34-0410-b5e6-96231b3b80d8
2012-08-17Assert that dominates is not given a multiple edge. Finding out if we haveRafael Espindola
multiple edges between two blocks is linear. If the caller is iterating all edges leaving a BB that would be a square time algorithm. It is more efficient to have the callers handle that case. Currently the only callers are: * GVN: already avoids the multiple edge case. * Verifier: could only hit this assert when looking at an invalid invoke. Since it already rejects the invoke, just avoid computing the dominance for it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@162113 91177308-0d34-0410-b5e6-96231b3b80d8
2012-08-16Teach GVN to reason about edges dominating uses. This allows it to handle casesRafael Espindola
where some fact lake a=b dominates a use in a phi, but doesn't dominate the basic block itself. This feature could also be implemented by splitting critical edges, but at least with the current algorithm reasoning about the dominance directly is faster. The time for running "opt -O2" in the testcase in pr10584 is 1.003 times slower and on gcc as a single file it is 1.0007 times faster. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@162023 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
2012-08-07The dominance computation already has logic for computing if an edge dominatesRafael Espindola
a use or a BB, but it is inline in the handling of the invoke instruction. This patch refactors it so that it can be used in other cases. For example, in define i32 @f(i32 %x) { bb0: %cmp = icmp eq i32 %x, 0 br i1 %cmp, label %bb2, label %bb1 bb1: br label %bb2 bb2: %cond = phi i32 [ %x, %bb0 ], [ 0, %bb1 ] %foo = add i32 %cond, %x ret i32 %foo } GVN should be able to replace %x with 0 in any use that is dominated by the true edge out of bb0. In the above example the only such use is the one in the phi. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@161429 91177308-0d34-0410-b5e6-96231b3b80d8

2012-08-03Move the "findUsedStructTypes" functionality outside of the Module class.Bill Wendling
The "findUsedStructTypes" method is very expensive to run. It needs to be optimized so that LTO can run faster. Splitting this method out of the Module class will help this occur. For instance, it can keep a list of seen objects so that it doesn't process them over and over again. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@161228 91177308-0d34-0410-b5e6-96231b3b80d8

2012-07-20Fix a dangling StringRef bug in the auto upgrader. In one case, we resetChandler Carruth
CI's name, and then used the StringRef pointing at its old name. I'm fixing it by storing the name in a std::string, and hoisting the renaming logic to happen always. This is nicer anyways as it will allow the upgraded IR to have the same names as the input IR in more cases. Another bug found by AddressSanitizer. Woot. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@160572 91177308-0d34-0410-b5e6-96231b3b80d8

2012-07-18More replacing of target-dependent intrinsics with target-indepdent Joel Jones
intrinsics. The second instruction(s) to be handled are the vector versions of count set bits (ctpop). The changes here are to clang so that it generates a target independent vector ctpop when it sees an ARM dependent vector bits set count. The changes in llvm are to match the target independent vector ctpop and in VMCore/AutoUpgrade.cpp to update any existing bc files containing ARM dependent vector pop counts with target-independent ctpops. There are also changes to an existing test case in llvm for ARM vector count instructions and to a test for the bitcode upgrade. <rdar://problem/11892519> There is deliberately no test for the change to clang, as so far as I know, no consensus has been reached regarding how to test neon instructions in clang; q.v. <rdar://problem/8762292> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@160410 91177308-0d34-0410-b5e6-96231b3b80d8

2012-06-29Move llvm/Support/IRBuilder.h -> llvm/IRBuilder.hChandler Carruth
This was always part of the VMCore library out of necessity -- it deals entirely in the IR. The .cpp file in fact was already part of the VMCore library. This is just a mechanical move. I've tried to go through and re-apply the coding standard's preferred header sort, but at 40-ish files, I may have gotten some wrong. Please let me know if so. I'll be committing the corresponding updates to Clang and Polly, and Duncan has DragonEgg.
