2009-04-07Driver: Manually translate a number of -f with no- variants options toDaniel Dunbar
clang. - We will eventually want some more driver infrastructre for this probably. - For now, the clang-cc interface stays relatively the same, but we don't accept multiple instances anymore, or the [no-] variants directly. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@68550 91177308-0d34-0410-b5e6-96231b3b80d8
2009-03-24Rename clang to clang-cc.Daniel Dunbar
Tests and drivers updated, still need to shuffle dirs. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@67602 91177308-0d34-0410-b5e6-96231b3b80d8
2009-02-17add support for -fno-math-errno, and validate that it affects sema properly.Chris Lattner

2008-05-19Make the unused expression warning a bit less aggressive (found in PHP Eli Friedman
code). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@51276 91177308-0d34-0410-b5e6-96231b3b80d8
2007-10-11rename -parse-ast-print to -ast-printChris Lattner
rename -parse-ast-dump to -ast-dump remove -parse-ast, which is redundant with -fsyntax-only git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@42852 91177308-0d34-0410-b5e6-96231b3b80d8
2007-09-26Removed option "-parse-ast-check" from clang driver. This is now implementedTed Kremenek
using "-parse-ast -verify". Updated all test cases (using a sed script) that invoked -parse-ast-check to now use -parse-ast -verify. Fixed a bug where using "-verify" instead of "-parse-ast-check" would not correctly create the DiagClient needed to accumulate diagnostics. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@42365 91177308-0d34-0410-b5e6-96231b3b80d8
2007-08-31Fix a bug/missing-feature Ted noticed: the 'unused' warning should notChris Lattner
warn about the last stmt in a stmtexpr, f.e. there should be no warning for: int maxval_stmt_expr(int x, int y) { return ({int _a = x, _b = y; _a > _b ? _a : _b; }); } git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@41655 91177308-0d34-0410-b5e6-96231b3b80d8
2007-08-27Add Type::getAsBuiltinType() and Type::builtinTypesAreCompatible().Steve Naroff
Modified Type::typesAreCompatible() to use the above. This fixes the following bug submitted by Keith Bauer (thanks!). int equal(char *a, const char *b) { return a == b; } Also tweaked Sema::CheckCompareOperands() to ignore the qualifiers when comparing two pointer types (though it doesn't relate directly to this bug). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@41476 91177308-0d34-0410-b5e6-96231b3b80d8
