2015-09-03[WebAssembly] Initial WebAssembly support in clangDan Gohman1-0/+2
This implements basic support for compiling (though not yet assembling or linking) for a WebAssembly target. Note that ABI details are not yet finalized, and may change. Differential Revision: http://reviews.llvm.org/D12002 llvm-svn: 246814

2013-07-24Use ARM-style representation for C++ method pointers under PNaCl/EmscriptenMark Seaborn1-0/+3
Before this change, Clang uses the x86 representation for C++ method pointers when generating code for PNaCl. However, the resulting code will assume that function pointers are 0 mod 2. This assumption is not safe for PNaCl, where function pointers could have any value (especially in future sandboxing models). So, switch to using the ARM representation for PNaCl code, which makes no assumptions about the alignment of function pointers. Since we're changing the "le32" target, this change also applies to Emscripten. The change is beneficial for Emscripten too. Emscripten has a workaround to make function pointers 0 mod 2. This change would allow the workaround to be removed. See: https://code.google.com/p/nativeclient/issues/detail?id=3450 llvm-svn: 187051
2012-05-01Restructure some of the member-pointer tests, implicitlyJohn McCall1-52/+67
removing some that were added without a triple (and moving their tests into files that appropriately test multiple architectures). llvm-svn: 155920
2012-02-15Split reinterpret_casts of member pointers out from CK_BitCast; thisJohn McCall1-0/+40
is general goodness because representations of member pointers are not always equivalent across member pointer types on all ABIs (even though this isn't really standard-endorsed). Take advantage of the new information to teach IR-generation how to do these reinterprets in constant initializers. Make sure this works when intermingled with hierarchy conversions (although this is not part of our motivating use case). Doing this in the constant-evaluator would probably have been better, but that would require a *lot* of extra structure in the representation of constant member pointers: you'd really have to track an arbitrary chain of hierarchy conversions and reinterpretations in order to get this right. Ultimately, this seems less complex. I also wasn't quite sure how to extend the constant evaluator to handle foldings that we don't actually want to treat as extended constant expressions. llvm-svn: 150551

2010-08-23Abstract out everything having to do with member pointers into the ABIJohn McCall1-2/+2
class; they should just be completely opaque throughout IR gen now, although I haven't really audited that. Fix a bug apparently inherited from gcc-4.2 where we failed to null-check member data pointers when performing derived-to-base or base-to-derived conversions on them. llvm-svn: 111789

llvm-svn: 111777
2010-08-22Experiment with using first-class aggregates to represent member functionJohn McCall1-30/+22
pointers. I find the resulting code to be substantially cleaner, and it makes it very easy to use the same APIs for data member pointers (which I have conscientiously avoided here), and it avoids a plethora of potential inefficiencies due to excessive memory copying, but we'll have to see if it actually works. llvm-svn: 111776
2010-08-22Abstract out member-pointer creation. I'm really unhappy about the currentJohn McCall1-0/+20
duplication between the constant and non-constant paths in all of this. Implement ARM ABI semantics for member pointer constants and conversion. llvm-svn: 111772

2009-12-15Update tests to use %clang_cc1 instead of 'clang-cc' or 'clang -cc1'.Daniel Dunbar1-1/+1
- This is designed to make it obvious that %clang_cc1 is a "test variable" which is substituted. It is '%clang_cc1' instead of '%clang -cc1' because it can be useful to redefine what gets run as 'clang -cc1' (for example, to set a default target). llvm-svn: 91446

- FileCheck is a *huuuuge* improvement here. - Still feels like we could use a better tool for this though, either teach llvm-dis to spit out the FileCheck syntax, or provide another tool to turn a .ll into a "matchable" input. - Also on my Christmas list is better FileCheck diagnostics with missing variables or mismatches. llvm-svn: 86800
