2010-04-16Remove this hard-coded buffer size. In some basic experiments preprocessingDan Gohman
large files, this doesn't seem significantly better than just letting raw_ostream pick a buffer size. This code predates raw-ostream's automatic buffer sizing; in fact, it was introduced as part of the code which would eventually become raw_ostream. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@101473 91177308-0d34-0410-b5e6-96231b3b80d8

2010-04-16Fix a bug in caret-line-pruning logic that only happens when we have aDouglas Gregor
source line wider than the terminal where the associated fix-it line is longer than the caret line. Previously, we would crash in this case, which was rather unfortunate. Fixes <rdar://problem/7856226>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@101426 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-15Audit uses of Sema::LookupSingleName for those lookups that areDouglas Gregor
intended for redeclarations, fixing those that need it. Fixes PR6831. This uncovered an issue where the C++ type-specifier-seq parsing logic would try to perform name lookup on an identifier after it already had a type-specifier, which could also lead to spurious ambiguity errors (as in PR6831, but with a different test case). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@101419 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-15Feed proper source-location information into Sema::LookupSingleResult,Douglas Gregor

2010-04-15Fix PR 6844, a regression caused by the introduction of llvm_unreachable for ↵Ted Kremenek
the default case in GRExprEngine::Visit (in r101129). Instead, enumerate all Stmt cases and have no 'default' case in the switch statement. When we encounter a Stmt we don't handle, we should explicitly add it to the switch statement. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@101378 91177308-0d34-0410-b5e6-96231b3b80d8

2010-04-15Fix a few cases where enum constant handling was usingDouglas Gregor
ASTContext::getTypeSize() rather than ASTContext::getIntWidth() for the width of an integral type. The former includes padding for bools (to the target's size) while the latter does not, so we woud end up zero-extending bools to the target width when we shouldn't. Fixes a crash-on-valid in the included test. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@101372 91177308-0d34-0410-b5e6-96231b3b80d8

2010-04-15Add TargetInfo::useBitfieldTypeAlignment().Daniel Dunbar
- Used to determine whether the alignment of the type in a bit-field is respected when laying out structures. The default is true, targets can override this as needed. - This is designed to correspond to the PCC_BITFIELD_TYPE_MATTERS macro in gcc. The AST/Sema implementation only affects one line, unless I have forgotten something. I'd appreciate further review. - IRgen still needs to be updated to fully support this (which is effectively PR5591). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@101356 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-15Driver/Frontend: Add support for -mllvm, which forwards options to the LLVM ↵Daniel Dunbar
option parser. - Note that this is a behavior change, previously -mllvm at the driver level forwarded to clang -cc1. The driver does a little magic to make sure that '-mllvm -disable-llvm-optzns' works correctly, but other users will need to be updated to use -Xclang. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@101354 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-15IRgen: Change CGBitFieldInfo to take the AccessInfo as constructor ↵Daniel Dunbar
arguments, it is now an immutable object. Also, add some checking of various invariants that should hold on the CGBitFieldInfo access. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@101345 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-15IRgen: Eliminate now unused fields from CGBitFieldInfo.Daniel Dunbar
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@101344 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-15IRgen: (Reapply 101222, with fixes) Move EmitStoreThroughBitfieldLValue to ↵Daniel Dunbar
use new CGBitfieldInfo::AccessInfo decomposition, instead of computing the access policy itself. - Sadly, this doesn't seem to give any .ll size win so far. It is possible to make this routine significantly smarter & avoid various shifting, masking, and zext/sext, but I'm not really convinced it is worth it. It is tricky, and this is really instcombine's job. - No intended functionality change; the test case is just to increase coverage & serves as a demo file, it worked before this commit. The new fixes from r101222 are: 1. The shift to the target position needs to occur after the value is extended to the correct size. This broke Clang bootstrap, among other things no doubt. 2. Swap the order of arguments to OR, to get a tad more constant folding. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@101339 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-15Rewrite handling of 64-bit palignr intrinsics to be vector shuffles.Eric Christopher
Stop multiplying constant by 8 accordingly in the header and change intrinsic definition for what types we expect. Add to existing palignr test to check that we're emitting the correct things. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@101332 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-15Warn about non-aggregate classes with no user-declared constructorsDouglas Gregor
that have reference or const scalar members, since those members can never be initializer or modified. Fixes <rdar://problem/7804350>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@101316 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-14Always diagnose and complain about problems inDouglas Gregor
ResolveAddressOfOverloadedFunction when asked to complain. Previously, we had some weird handshake where ResolveAddressOfOverloadedFunction expected its caller to handle some of the diagnostics but not others, and yet there was no way for the caller to know which case we were in. Eliminate this madness, fixing <rdar://problem/7765884>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@101312 91177308-0d34-0410-b5e6-96231b3b80d8

2010-04-14Once we've emitted a fatal diagnostic, keep counting errors but with aDouglas Gregor
separate count of "suppressed" errors. This way, semantic analysis bits that depend on the error count to determine whether problems occured (e.g., some template argument deduction failures, jump-scope checking) will not get confused. The actual problem here is that a missing #include (which is a fatal error) could cause the jump-scope checker to run on invalid code, which it is not prepared to do. Trivial fix for both <rdar://problem/7775941> and <rdar://problem/7775709>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@101297 91177308-0d34-0410-b5e6-96231b3b80d8

2010-04-14Thread a Scope pointer into BuildRecoveryCallExpr to help typoDouglas Gregor

2010-04-14Teach typo correction about various language keywords. We can'tDouglas Gregor
generally recover from typos in keywords (since we would effectively have to mangle the token stream). However, there are still benefits to typo-correcting with keywords: - We don't make stupid suggestions when the user typed something that is similar to a keyword. - We can suggest the keyword in a diagnostic (did you mean "static_cast"?), even if we can't recover and therefore don't have a fix-it. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@101274 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-14Return the corrected DeclarationName from Sema::CorrectTypo ratherDouglas Gregor
than just a bool indicating that correction occurred. No actual functionality change (it's still always used like a bool), but this refactoring will be used to support typo correction to keywords. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@101259 91177308-0d34-0410-b5e6-96231b3b80d8

IRgen record layout, which this code doesn't need to depend on. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@101257 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-14When diagnosing suspicious precedence or assignments, move the fix-itDouglas Gregor
that adds parentheses from the main diagnostic down to a new note. This way, when the fix-it represents a choice between two options, each of the options is associted with a note. There is no default option in such cases. For example: /Users/dgregor/t.c:2:9: warning: & has lower precedence than ==; == will be evaluated first [-Wparentheses] if (x & y == 0) { ^~~~~~~~ /Users/dgregor/t.c:2:9: note: place parentheses around the & expression to evaluate it first if (x & y == 0) { ^ ( ) /Users/dgregor/t.c:2:9: note: place parentheses around the == expression to silence this warning if (x & y == 0) { ^ ( ) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@101249 91177308-0d34-0410-b5e6-96231b3b80d8
