2014-04-25Introduce an Emscripten C++ ABI.Dan Gohman
Emscripten uses the Itanium C++ ABI for most things, except that it uses ARM C++ ABI pointers to member functions, to avoid the overhead of aligning functions.
2014-04-09set the emscripten backend's atomic widths to 32Alon Zakai
2014-03-03Set the natural stack alignment for asm.js to 16 bytes.Dan Gohman
2014-02-24Introduce the asmjs-unknown-emscripten target triple.Dan Gohman
Notable changes from le32-unknown-nacl so far include: - Set i32 as the legal integer set, to help the optimizer avoid creating needlessly inefficient code for asm.js. - We can use llvm.pow. - Don't predefine __ELF__ or __pnacl__ so that we don't need to undefine them later. - Do predefine asm.js and Emscripten macros, so that we don't need to define them later. - Don't provide __has_feature(pnacl).

2013-05-06Add SystemZ supportUlrich Weigand
This patch then adds all the usual platform-specific pieces for SystemZ: driver support, basic target info, register names and constraints, ABI info and vararg support. It also adds new tests to verify pre-defined macros and inline asm, and updates a test for the minimum alignment change. This version of the patch incorporates feedback from reviews by Eric Christopher and John McCall. Thanks to all reviewers! Patch by Richard Sandiford. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@181211 91177308-0d34-0410-b5e6-96231b3b80d8
2013-05-06Allow targets to define minimum alignment for global variablesUlrich Weigand
This patch adds a new common code feature that allows platform code to request minimum alignment of global symbols. The background for this is that on SystemZ, the most efficient way to load addresses of global symbol is the LOAD ADDRESS RELATIVE LONG (LARL) instruction. This instruction provides PC-relative addressing, but only to *even* addresses. For this reason, existing compilers will guarantee that global symbols are always aligned to at least 2. [ Since symbols would otherwise already use a default alignment based on their type, this will usually only affect global objects of character type or character arrays. ] GCC also allows creating symbols without that extra alignment by using explicit "aligned" attributes (which then need to be used on both definition and each use of the symbol). To enable support for this with Clang, this patch adds a TargetInfo::MinGlobalAlign variable that provides a global minimum for the alignment of every global object (unless overridden via explicit alignment attribute), and adds code to respect this setting. Within this patch, no platform actually sets the value to anything but the default 1, resulting in no change in behaviour on any existing target. This version of the patch incorporates feedback from reviews by Eric Christopher and John McCall. Thanks to all reviewers!

2013-05-03When building a module, forward diagnostics to the outer diagnostic consumer.Douglas Gregor
Previously, we would clone the current diagnostic consumer to produce a new diagnostic consumer to use when building a module. The problem here is that we end up losing diagnostics for important diagnostic consumers, such as serialized diagnostics (where we'd end up with two diagnostic consumers writing the same output file). With forwarding, the diagnostics from all of the different modules being built get forwarded to the one serialized-diagnostic consumer and are emitted in a sane way.

2013-04-05AArch64: bring predefines in line with most recent ACLE documentTim Northover
The prefixes and names used are now identical to 32-bit ARM, which is also expected to remain unchanged. If we made this change after a release, we'd probably have to support both variants for a while, but I think since AArch64 exists only on trunk now, it's acceptable to simply swap them now. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@178870 91177308-0d34-0410-b5e6-96231b3b80d8

2013-03-20<rdar://problem/10796651> Introduce configuration macros into module maps.Douglas Gregor
Configuration macros are macros that are intended to alter how a module works, such that we need to build different module variants for different values of these macros. A module can declare its configuration macros, in which case we will complain if the definition of a configation macro on the command line (or lack thereof) differs from the current preprocessor state at the point where the module is imported. This should eliminate some surprises when enabling modules, because "#define CONFIG_MACRO ..." followed by "#include <module/header.h>" would silently ignore the CONFIG_MACRO setting. At least it will no longer be silent about it. Configuration macros are eventually intended to help reduce the number of module variants that need to be built. When the list of configuration macros for a module is exhaustive, we only need to consider the settings for those macros when building/finding the module, which can help isolate modules for various project-specific -D flags that should never affect how modules are build (but currently do). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@177466 91177308-0d34-0410-b5e6-96231b3b80d8

2013-02-27Refine SourceManager's isBeforeInTranslationUnit() cache to have more entries.Ted Kremenek
isBeforeInTranslationUnit() uses a cache to reduce the expensive work to compute a common ancestor for two FileIDs. This work is very expensive, so even caching the latest used FileIDs was a big win. A closer analysis of the cache before, however, shows that the cache access pattern would oscillate between a working set of FileIDs, and thus caching more pairs would be profitable. This patch adds a side table for extending caching. This side table is bounded in size (experimentally determined in this case from a simple Objective-C project), and when the table gets too large we fall back to the single entry caching before as before. On Sketch (a small example Objective-C project), this optimization reduces -fsyntax-only time on SKTGraphicView.m by 5%. This is for a project that is already using PCH.
