2012-07-06Add -ffp-contract = { fast | on | off } command line option support.Lang Hames
This flag sets the 'fp-contract' mode, which controls the formation of fused floating point operations. Available modes are: - Fast: Form fused operations anywhere. - On: Form fused operations where allowed by FP_CONTRACT. This is the default mode. - Off: Don't form fused operations (in future this may be relaxed to forming fused operations where it can be proved that the result won't be affected). Currently clang doesn't support the FP_CONTRACT pragma, so the 'On' and 'Off' modes are equivalent. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@159794 91177308-0d34-0410-b5e6-96231b3b80d8
2012-07-06Implement AST classes for comments, a real parser for Doxygen comments and aDmitri Gribenko
very simple semantic analysis that just builds the AST; minor changes for lexer to pick up source locations I didn't think about before. Comments AST is modelled along the ideas of HTML AST: block and inline content. * Block content is a paragraph or a command that has a paragraph as an argument or verbatim command. * Inline content is placed within some block. Inline content includes plain text, inline commands and HTML as tag soup. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@159790 91177308-0d34-0410-b5e6-96231b3b80d8

2012-07-04Drop the ASTContext.h include from Stmt.h and fix up transitive users.Benjamin Kramer
This required moving the ctors for IntegerLiteral and FloatingLiteral out of line which shouldn't change anything as they are usually called through Create methods that are already out of line. ASTContext::Deallocate has been a nop for a long time, drop it from ASTVector and make it independent from ASTContext.h Pass the StorageAllocator directly to AccessedEntity so it doesn't need to have a definition of ASTContext around. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@159718 91177308-0d34-0410-b5e6-96231b3b80d8

2012-07-02Significantly simplify CGExprAgg's logic about ignored results:John McCall
if we want to ignore a result, the Dest will be null. Otherwise, we must copy into it. This means we need to ensure a slot when loading from a volatile l-value.

2012-06-26block literal irgen: several improvements on naming blockFariborz Jahanian
literal helper functions. All helper functions (global and locals) use block_invoke as their prefix. Local literal helper names are prefixed by their enclosing mangled function names. Blocks in non-local initializers (e.g. a global variable or a C++11 field) are prefixed by their mangled variable name. The descriminator number added to end of the name starts off with blank (for first block) and _<N> (for the N+2-th block). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@159206 91177308-0d34-0410-b5e6-96231b3b80d8

2012-06-23Support the tls_model attribute (PR9788)Hans Wennborg
This adds support for the tls_model attribute. This allows the user to choose a TLS model that is better than what LLVM would select by default. For example, a variable might be declared as: __thread int x __attribute__((tls_model("initial-exec"))); if it will not be used in a shared library that is dlopen'ed. This depends on LLVM r159077. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@159078 91177308-0d34-0410-b5e6-96231b3b80d8

2012-06-20Restructure how the driver communicates information about theJohn McCall
target Objective-C runtime down to the frontend: break this down into a single target runtime kind and version, and compute all the relevant information from that. This makes it relatively painless to add support for new runtimes to the compiler. Make the new -cc1 flag, -fobjc-runtime=blah-x.y.z, available at the driver level as a better and more general alternative to -fgnu-runtime and -fnext-runtime. This new concept of an Objective-C runtime also encompasses what we were previously separating out as the "Objective-C ABI", so fragile vs. non-fragile runtimes are now really modelled as different kinds of runtime, paving the way for better overall differentiation. As a sort of special case, continue to accept the -cc1 flag -fobjc-runtime-has-weak, as a sop to PLCompatibilityWeak. I won't go so far as to say "no functionality change", even ignoring the new driver flag, but subtle changes in driver semantics are almost certainly not intended. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@158793 91177308-0d34-0410-b5e6-96231b3b80d8
