* [ms-cxxabi] Add a new calling convention that swaps 'this' and 'sret'Reid Kleckner2014-01-31
| | | | | | | | | | | | | | | | | | | | MSVC always places the 'this' parameter for a method first. The implicit 'sret' pointer for methods always comes second. We already implement this for __thiscall by putting sret parameters on the stack, but __cdecl methods require putting both parameters on the stack in opposite order. Using a special calling convention allows frontends to keep the sret parameter first, which avoids breaking lots of assumptions in LLVM and Clang. Fixes PR15768 with the corresponding change in Clang.

* 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.

Rename the 'Assembly' include directory to 'AsmParser' to match the library name and the only functionality left their -- printing has been in the core IR library for quite some time. Update all of the #includes to match. All of this started because I wanted to have the layering in good shape before I started adding support for printing LLVM IR using the new pass infrastructure, and commandline support for the new pass infrastructure. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@198688 91177308-0d34-0410-b5e6-96231b3b80d8

* Remove linkonce_odr_auto_hide.Rafael Espindola2013-11-01
| | | | | | | | | | | | | | | linkonce_odr_auto_hide was in incomplete attempt to implement a way for the linker to hide symbols that are known to be available in every TU and whose addresses are not relevant for a particular DSO. It was redundant in that it all its uses are equivalent to linkonce_odr+unnamed_addr. Unlike those, it has never been connected to clang or llvm's optimizers, so it was effectively dead. Given that nothing produces it, this patch just nukes it (other than the llvm-c enum value). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@193865 91177308-0d34-0410-b5e6-96231b3b80d8

* Target/X86: Add explicit Win64 and System V/x86-64 calling conventions.Charles Davis2013-07-12
| | | | | | | | | | | | | | | Summary: This patch adds explicit calling convention types for the Win64 and System V/x86-64 ABIs. This allows code to override the default, and use the Win64 convention on a target that wants to use SysV (and vice-versa). This is needed to implement the `ms_abi` and `sysv_abi` GNU attributes.

* Remove support for versioned debug info.David Blaikie2013-03-11
| | | | | | | | | | | | | | | | | | | | | | | | Versioned debug info support has been a burden to maintain & also compromised current debug info verification by causing test cases testing old debug info to remain rather than being updated to the latest. It also makes it hard to add or change the metadata schema by requiring various backwards-compatibility in the DI* hierarchy. So it's being removed in preparation for new changes to the schema to tidy up old/unnecessary fields and add new fields needed for new debug info (well, new to LLVM at least). The more surprising part of this is the changes to DI*::Verify - this became necessary due to the changes to AsmWriter. AsmWriter was relying on the version test to decide which bits of metadata were actually debug info when printing the comment annotations. Without the version information the tag numbers were too common & it would print debug info on random metadata that happened to start with an integer that matched a tag number. Instead this change makes the Verify functions more precise (just adding "number of operands" checks - not type checking those operands yet) & relies on that to decide which metadata is debug info metadata. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@176838 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | | This emits the attribute groups that are used by the functions. (It currently doesn't print out return type or parameter attributes within attribute groups.) Note: The functions still retrieve their attributes from the "old" bitcode format (using the deprecated 'Raw()' method).

This will be addressed in a future commit. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@174867 91177308-0d34-0410-b5e6-96231b3b80d8

* Move all of the header files which are involved in modelling the LLVM IRChandler Carruth2013-01-02
| | | | | | | | | | | | | | | | | | | | | into their new header subdirectory: include/llvm/IR. This matches the directory structure of lib, and begins to correct a long standing point of file layout clutter in LLVM. There are still more header files to move here, but I wanted to handle them in separate commits to make tracking what files make sense at each layer easier. The only really questionable files here are the target intrinsic tablegen files. But that's a battle I'd rather not fight today. I've updated both CMake and Makefile build systems (I think, and my tests think, but I may have missed something). I've also re-sorted the includes throughout the project.

* Rename VMCore directory to IR.Chandler Carruth2013-01-02
Aside from moving the actual files, this patch only updates the build system and the source file comments under lib/... that are relevant. I'll be updating other docs and other files in smaller subsequnet commits. While I've tried to test this, but it is entirely possible that there will still be some build system fallout. Also, note that I've not changed the library name itself: libLLVMCore.a is still the library name. I'd be interested in others' opinions about whether we should rename this as well (I think we should, just not sure what it might break) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@171359 91177308-0d34-0410-b5e6-96231b3b80d8
