2012-07-13This is one of the first steps at moving to replace target-dependent Joel Jones
intrinsics with target-indepdent intrinsics. The first instruction(s) to be handled are the vector versions of count leading zeros (ctlz). The changes here are to clang so that it generates a target independent vector ctlz when it sees an ARM dependent vector ctlz. The changes in llvm are to match the target independent vector ctlz and in VMCore/AutoUpgrade.cpp to update any existing bc files containing ARM dependent vector ctlzs with target-independent ctlzs. There are also changes to an existing test case in llvm for ARM vector count instructions and a new test for the bitcode upgrade. <rdar://problem/11831778> 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@160201 91177308-0d34-0410-b5e6-96231b3b80d8

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

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

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.
