2012-12-11Speed up looking up static diagnostic infos.Benjamin Kramer
Instead of doing a binary search over the whole diagnostic table (which weighs a whopping 48k on x86_64), use the existing enums to compute the index in the table. This avoids loading any unneeded data from the table and avoids littering CPU caches with it. This code is in a hot path for code with many diagnostics. 1% speedup on -fsyntax-only gcc.c, which emits a lot of warnings. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@169890 91177308-0d34-0410-b5e6-96231b3b80d8

2012-12-11Rename StmtDumper::DumpSubTree() to dumpStmt()Alexander Kornienko
Summary: Also rename DumpDeclarator() to dumpDecl(). Once Decl dumping is added, these will be the two main methods of the class, so this is just for consistency in naming. There was a DumpStmt() method already, but there was no point in having it, so I have merged it into VisitStmt(). Similarly, DumpExpr() is merged into VisitExpr().

2012-12-09Cleanup and fix an assert that was mis-firing.Chandler Carruth
Note that there is no test suite update. This was found by a couple of tests failing when the test suite was run on a powerpc64 host (thanks Roman!). The tests don't specify a triple, which might seem surprising for a codegen test. But in fact, these tests don't even inspect their output. Not at all. I could add a bunch of triples to these tests so that we'd get the test coverage for normal builds, but really someone needs to go through and add actual *tests* to these tests. =[ The ones in question are: test/CodeGen/bitfield-init.c test/CodeGen/union.c git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@169694 91177308-0d34-0410-b5e6-96231b3b80d8
2012-12-09Add a test case that I've been using to clarify the bitfield layout forChandler Carruth
both LE and BE targets. AFAICT, Clang get's this correct for PPC64. I've compared it to GCC 4.8 output for PPC64 (thanks Roman!) and to my limited ability to read power assembly, it looks functionally equivalent. It would be really good to fill in the assertions on this test case for x86-32, PPC32, ARM, etc., but I've reached the limit of my time and energy... Hopefully other folks can chip in as it would be good to have this in place to test any subsequent changes. To those who care about PPC64 performance, a side note: there is some *obnoxiously* bad code generated for these test cases. It would be worth someone's time to sit down and teach the PPC backend to pattern match these IR constructs better. It appears that things like '(shr %foo, <imm>)' turn into 'rldicl R, R, 64-<imm>, <imm>' or some such. They don't even get combined with other 'rldicl' instructions *immediately adjacent*. I'll add a couple of these patterns to the README, but I think it would be better to look at all the patterns produced by this and other bitfield access code, and systematically build up a collection of patterns that efficiently reduce them to the minimal code. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@169693 91177308-0d34-0410-b5e6-96231b3b80d8
2012-12-09Fix the bitfield record layout in codegen for big endian targets.Chandler Carruth
This was an egregious bug due to the several iterations of refactorings that took place. Size no longer meant what it original did by the time I finished, but this line of code never got updated. Unfortunately we had essentially zero tests for this in the regression test suite. =[ I've added a PPC64 run over the bitfield test case I've been primarily using. I'm still looking at adding more tests and making sure this is the *correct* bitfield access code on PPC64 linux, but it looks pretty close to me, and it is *worlds* better than before this patch as it no longer asserts! =] More commits to follow with at least additional tests and maybe more fixes.

2012-12-08Finish implementing 'selected constructor' rules for triviality in C++11. InRichard Smith
the cases where we can't determine whether special members would be trivial while building the class, we eagerly declare those special members. The impact of this is bounded, since it does not trigger implicit declarations of special members in classes which merely *use* those classes. In order to determine whether we need to apply this rule, we also need to eagerly declare move operations and destructors in cases where they might be deleted. If a move operation were supposed to be deleted, it would instead be suppressed, and we could need overload resolution to determine if we fall back to a trivial copy operation. If a destructor were implicitly deleted, it would cause the move constructor of any derived classes to be suppressed. As discussed on cxx-abi-dev, C++11's selected constructor rules are also retroactively applied as a defect resolution in C++03 mode, in order to identify that class B has a non-trivial copy constructor (since it calls A's constructor template, not A's copy constructor): struct A { template<typename T> A(T &); }; struct B { mutable A a; }; git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@169673 91177308-0d34-0410-b5e6-96231b3b80d8
