* The x86-64 ABI says that a bool is only guaranteed to be sign-extended to a byteCameron Zwarich2011-03-16
| | | | | | | | | | | rather than an int. Thankfully, this only causes LLVM to miss optimizations, not generate incorrect code. This just fixes the zext at the return. We still insert an i32 ZextAssert when reading a function's arguments, but it is followed by a truncate and another i8 ZextAssert so it is not optimized. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@127766 91177308-0d34-0410-b5e6-96231b3b80d8

* Enable support for vector sext and trunc:Nadav Rotem2011-02-24
| | | | | | | | | | | | Limit the folding of any_ext and sext into the load operation to scalars. Limit the active-bits trunc optimization to scalars. Document vector trunc and vector sext in LangRef. Similar to commit 126080 (for enabling zext). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@126424 91177308-0d34-0410-b5e6-96231b3b80d8
* Fix 9267; Add vector zext support.Nadav Rotem2011-02-20
| | | | | | | | | | The DAGCombiner folds the zext into complex load instructions.

* Add a clarification about merging constants with and without unnamed_addr.Rafael Espindola2011-01-15
| | | | git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@123530 91177308-0d34-0410-b5e6-96231b3b80d8
* First step in fixing PR8927:Rafael Espindola2011-01-08
| | | | | | | | | | | | | | | | | | | Add a unnamed_addr bit to global variables and functions. This will be used to indicate that the address is not significant and therefore the constant or function can be merged with others. If an optimization pass can show that an address is not used, it can set this. Examples of things that can have this set by the FE are globals created to hold string literals and C++ constructors. Adding unnamed_addr to a non-const global should have no effect unless an optimization can transform that global into a constant. Aliases are not allowed to have unnamed_addr since I couldn't figure out any use for it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@123063 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | SrcMgrDiagHandler, we can improve clang diagnostics for inline asm: instead of reporting them on a source line of the original line, we can report it on the correct line wherever the string literal came from. For something like this: void foo() { asm("push %rax\n" ".code32\n"); } we used to get this: (note that the line in t.c isn't helpful) t.c:4:7: error: warning: ignoring directive for now asm("push %rax\n" ^ <inline asm>:2:1: note: instantiated into assembly here .code32 ^ now we get: t.c:5:8: error: warning: ignoring directive for now ".code32\n" ^ <inline asm>:2:1: note: instantiated into assembly here .code32 ^ Note that we're pointing to line 5 properly now. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@119488 91177308-0d34-0410-b5e6-96231b3b80d8

* Create the new linker type "linker_private_weak_def_auto".Bill Wendling2010-08-20
| | | | | | | | | | | | | It's similar to "linker_private_weak", but it's known that the address of the object is not taken. For instance, functions that had an inline definition, but the compiler decided not to inline it. Note, unlike linker_private and linker_private_weak, linker_private_weak_def_auto may have only default visibility. The symbols are removed by the linker from the final linked image (executable or dynamic library). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@111684 91177308-0d34-0410-b5e6-96231b3b80d8
