2009-02-17Change EmitConstantExpr to allow failure.Daniel Dunbar
IRgen no longer relies on isConstantInitializer, instead we just try to emit the constant. If that fails then in C we emit an error unsupported (this occurs when Sema accepted something that it doesn't know how to fold, and IRgen doesn't know how to emit) and in C++ we emit a guarded initializer. This ends up handling a few more cases, because IRgen was actually able to emit some of the constants Sema accepts but can't Evaluate(). For example, PR3398. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@64780 91177308-0d34-0410-b5e6-96231b3b80d8

2009-02-16Support IRgen of sqrt -> llvm.sqrt, pow -> llvm.pow.Daniel Dunbar
- Define pow[lf]?, sqrt[lf]? as builtins. - Add -fmath-errno option which binds to LangOptions.MathErrno - Add new builtin flag Builtin::Context::isConstWithoutErrno for functions which can be marked as const if errno isn't respected for math functions. Sema automatically marks these functions as const when they are defined, if MathErrno=0. - IRgen uses const attribute on sqrt and pow library functions to decide if it can use the llvm intrinsic. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@64689 91177308-0d34-0410-b5e6-96231b3b80d8

2009-02-14Add hook to add attributes to function declarations that we knowDouglas Gregor
about, whether they are builtins or not. Use this to add the appropriate "format" attribute to NSLog, NSLogv, asprintf, and vasprintf, and to translate builtin attributes (from Builtins.def) into actual attributes on the function declaration. Use the "printf" format attribute on function declarations to determine whether we should do format string checking, rather than looking at an ad hoc list of builtins and "known" function names. Be a bit more careful about when we consider a function a "builtin" in C++. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@64561 91177308-0d34-0410-b5e6-96231b3b80d8

2009-02-13Implicitly declare certain C library functions (malloc, strcpy, memmove,Douglas Gregor
etc.) when we perform name lookup on them. This ensures that we produce the correct signature for these functions, which has two practical impacts: 1) When we're supporting the "implicit function declaration" feature of C99, these functions will be implicitly declared with the right signature rather than as a function returning "int" with no prototype. See PR3541 for the reason why this is important (hint: GCC always predeclares these functions). 2) If users attempt to redeclare one of these library functions with an incompatible signature, we produce a hard error. This patch does a little bit of work to give reasonable error messages. For example, when we hit case #1 we complain that we're implicitly declaring this function with a specific signature, and then we give a note that asks the user to include the appropriate header (e.g., "please include <stdlib.h> or explicitly declare 'malloc'"). In case #2, we show the type of the implicit builtin that was incorrectly declared, so the user can see the problem. We could do better here: for example, when displaying this latter error message we say something like: 'strcpy' was implicitly declared here with type 'char *(char *, char const *)' but we should really print out a fake code line showing the declaration, like this: 'strcpy' was implicitly declared here as: char *strcpy(char *, char const *) This would also be good for printing built-in candidates with C++ operator overloading. The set of C library functions supported by this patch includes all functions from the C99 specification's <stdlib.h> and <string.h> that (a) are predefined by GCC and (b) have signatures that could cause codegen issues if they are treated as functions with no prototype returning and int. Future work could extend this set of functions to other C library functions that we know about. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@64504 91177308-0d34-0410-b5e6-96231b3b80d8
