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/cfe/trunk@160409 91177308-0d34-0410-b5e6-96231b3b80d8

Due to performance cost, this is an opt-in option placed under -Wassign-enum. // rdar://11824807 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@160382 91177308-0d34-0410-b5e6-96231b3b80d8
2012-07-17-Wobjc-literal-compare: don't warn when comparing against nil.Jordan Rose
Checks against nil often appear as guards in macros, and comparing Objective-C literals to nil has well-defined behavior (if tautological). On OS X, 'nil' has not been typed as 'id' since 10.6 (possibly earlier), so the warning was already not firing, but other runtimes continue to use ((id)0) or some variant. This change accepts comparisons to any null pointer; to keep it simple, it looks through all casts (not just casts to 'id'). PR13276 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@160379 91177308-0d34-0410-b5e6-96231b3b80d8
2012-07-17Add -Wobjc-string-compare under -Wobjc-literal-compare.Jordan Rose
Suggested by Ted, since string literal comparison is at least slightly more sensible than comparison of runtime literals. (Ambiguous language on developer.apple.com implies that strings are guaranteed to be uniqued within a translation unit and possibly across a linked binary.) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@160378 91177308-0d34-0410-b5e6-96231b3b80d8

2012-07-17-Wuninitialized: Split the classification of DeclRefExprs as initialization orRichard Smith
use out of TransferFunctions, and compute it in advance rather than on-the-fly. This allows us to handle compound assignments with DeclRefExprs on the RHS correctly, and also makes it trivial to treat const& function parameters as not initializing the argument.

2012-07-16Don't crash when emitting fixits following Unicode characters.Jordan Rose
This code is very sensitive to the difference between "columns" as printed and "bytes" (SourceManager columns). All variables are now named explicitly and our assumptions are (hopefully) documented as both comment and assertion. Whether parseable fixits should use byte offsets or Unicode character counts is pending discussion on the mailing list; currently the implementation uses bytes (and has no problems on lines containing multibyte characters). This has been added to the user manual. <rdar://problem/11877454> git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@160319 91177308-0d34-0410-b5e6-96231b3b80d8
