* Revert my commit in r199620 that added sections about namespaces to theChandler Carruth2014-01-20
| | | | | | | | | | | | | | | | | | coding standards, and instead fix the existing section. Thanks to Daniel Jasper for pointing out we already had a section devoted to this topic. Instead of adding sections, just hack on this section some. Also fix the example in the anonymous namespace section below it to agree with the new advice. As a re-cap, this switches the LLVM preferred style to never indent namespaces. Having two approaches just led to endless (and utterly pointless) debates about what was "small enough". This wasn't helping anyone. The no-indent rule is easy to understand and doesn't really make anything harder to read. Moreover, with tools like clang-format it is considerably nicer to have simple consistent rules. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@199637 91177308-0d34-0410-b5e6-96231b3b80d8
* Add some wording to the coding standards to say how to indent namespacesChandler Carruth2014-01-20
| | | | | | | | | | | (and to mention namespace ending comments). This is based on a quick discussion on the developer mailing list where there was essentially no objections to a simple and consistent rule. This should avoid future debates about whether or not a namespace is "big enough" to indent. It also matches clang-format's current behavior with LLVM source code which hasn't really seen any opposition in code reviews that I spot checked. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@199620 91177308-0d34-0410-b5e6-96231b3b80d8
* Add an inalloca flag to allocasReid Kleckner2014-01-17
| | | | | | | | | | | | | | | | Summary: The only current use of this flag is to mark the alloca as dynamic, even if its in the entry block. The stack adjustment for the alloca can never be folded into the prologue because the call may clear it and it has to be allocated at the top of the stack.

* Add two new calling conventions for runtime callsJuergen Ributzka2014-01-17
| | | | | | | | | | | | | | This patch adds two new target-independent calling conventions for runtime calls - PreserveMost and PreserveAll. The target-specific implementation for X86-64 is defined as following: - Arguments are passed as for the default C calling convention - The same applies for the return value(s) - PreserveMost preserves all GPRs - except R11 - PreserveAll preserves all GPRs and all XMMs/YMMs - except R11 Reviewed by Lang and Philip git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@199508 91177308-0d34-0410-b5e6-96231b3b80d8

* Decouple dllexport/dllimport from linkageNico Rieck2014-01-14
| | | | | | | | | | | | | | | | | | | Representing dllexport/dllimport as distinct linkage types prevents using these attributes on templates and inline functions. Instead of introducing further mixed linkage types to include linkonce and weak ODR, the old import/export linkage types are replaced with a new separate visibility-like specifier: define available_externally dllimport void @f() {} @Var = dllexport global i32 1, align 4 Linkage for dllexported globals and functions is now equal to their linkage without dllexport.

* Make the llvm mangler depend only on DataLayout.Rafael Espindola2014-01-03
| | | | | | | | | | | | | | Before this patch any program that wanted to know the final symbol name of a GlobalValue had to link with Target. This patch implements a compromise solution where the mangler uses DataLayout. This way, any tool that already links with Target (llc, clang) gets the exact behavior as before and new IR files can be mangled without linking with Target. With this patch the mangler is constructed with just a DataLayout and DataLayout is extended to include the information the Mangler needs. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@198438 91177308-0d34-0410-b5e6-96231b3b80d8
* Remove the 's' DataLayout specificationRafael Espindola2014-01-01
| | | | | | | | | | | | | | | | | | | | | | | During the years there have been some attempts at figuring out how to align byval arguments. A look at the commit log suggests that they were * Use the ABI alignment. * When that was not sufficient for x86-64, I added the 's' specification to DataLayout. * When that was not sufficient Evan added the virtual getByValTypeAlignment. * When even that was not sufficient, we just got the FE to add the alignment to the byval. This patch is just a simple cleanup that removes my first attempt at fixing the problem. I also added an AArch64 implementation of getByValTypeAlignment to make sure this patch is a nop. I also left the 's' parsing for backward compatibility. I will send a short email to llvmdev about the change for anyone maintaining an out of tree target. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@198287 91177308-0d34-0410-b5e6-96231b3b80d8

* Begin adding docs and IR-level support for the inalloca attributeReid Kleckner2013-12-19
| | | | | | | | | | | | | | | | | | | The inalloca attribute is designed to support passing C++ objects by value in the Microsoft C++ ABI. It behaves the same as byval, except that it always implies that the argument is in memory and that the bytes are never copied. This attribute allows the caller to take the address of an outgoing argument's memory and execute arbitrary code to store into it. This patch adds basic IR support, docs, and verification. It does not attempt to implement any lowering or fix any possibly broken transforms. When this patch lands, a complete description of this feature should appear at http://llvm.org/docs/InAlloca.html .

* CMake : optionaly enable LLVM to be compiled with -std=c++11 (default: off)Arnaud A. de Grandmaison2013-11-26
| | | | | | | | | | In some case, it may be required to build LLVM in C++11 mode, as some the subprojects (like lldb) requires it. This mimics the autoconf behaviour.
