* Ignore ConstantExpr in IgnoreParensReid Kleckner2018-12-261-0/+2
| | | | | | | | | | | | | | | | | | Summary: This moves it up from IgnoreParenImpCasts to IgnoreParens, so that more helpers ignore it. For most clients, this ensures that these helpers behave the same with and without C++17 enabled, which is what appears to introduce these new expression nodes.

* Remove the -cxx-abi command-line flag.Hans Wennborg2014-01-141-2/+2
| | | | | | | | | | | | | | | This makes the C++ ABI depend entirely on the target: MS ABI for -win32 triples, Itanium otherwise. It's no longer possible to do weird combinations. To be able to run a test with a specific ABI without constraining it to a specific triple, new substitutions are added to lit: %itanium_abi_triple and %ms_abi_triple can be used to get the current target triple adjusted to the desired ABI. For example, if the test suite is running with the i686-pc-win32 target, %itanium_abi_triple will expand to i686-pc-mingw32.

* [-cxx-abi microsoft] Mangle large integral constants correctlyDavid Majnemer2013-12-091-0/+38
| | | | | | | | | | | | | | | | | | | Testing has revealed that large integral constants (i.e. > INT64_MAX) are always mangled as-if they are negative, even in places where it would not make sense for them to be negative (like non-type template parameters of type unsigned long long). To address this, we change the way we model number mangling: always mangle as-if our number is an int64_t. This should result in correct results when we have large unsigned numbers. N.B. Bizarrely, things that are 32-bit displacements like vbptr offsets are mangled as-if they are unsigned 32-bit numbers. This is a pretty egregious waste of space, it would be a 4x savings if we could mangle it like a signed 32-bit number. Instead, we explicitly cast these displacements to uint32_t and let the mangler proceed. llvm-svn: 196771
* Parse: Do not 'HandleTopLevelDecl' on templated functions.David Majnemer2013-08-161-2/+11
| | | | | | | | | | | | | | | | Summary: HandleTopLevelDecl on a templated function leads us to try and mangle it. Reviewers: rsmith Reviewed By: rsmith CC: cfe-commits Differential Revision: http://llvm-reviews.chandlerc.com/D1412 llvm-svn: 188536
* [-cxx-abi microsoft] Mangle __uuidof correctly into template parametersDavid Majnemer2013-08-131-2/+16
| | | | | | | | | | | | | | | | | | | | | | | Summary: It seems that __uuidof introduces a global extern "C" declaration of type __s_GUID. However, our implementation of __uuidof does not provide such a declaration and thus must open-code the mangling for __uuidof in template parameters. This allows us to codegen scoped COM pointers and other such things. This fixes PR16836. Depends on D1356.

* [ms-cxxabi] Mangle variadic template parameter packsReid Kleckner2013-07-021-0/+23
| | | | | | | | | | | | | | Unlike Itanium, there is no code to indicate the beginning of a parameter pack. I tested this with MSVC 2013, which is the only version that implements variadic templates so far. This is needed to compile APInt.cpp for the MS C++ ABI.

* [ms-cxxabi] Mangle in an implicit 'E' for certain types on win64Reid Kleckner2013-05-141-1/+25
| | | | | | | | | | | | Most of the complexity of this patch is figuring out which types get the qualifier and which don't. If we implement __ptr32/64, then we should check the qualifier instead of assuming all pointers are 64-bit. This fixes PR13792. Patch by Warren Hunt! llvm-svn: 181825
* [ms-cxxabi] Fix a number of bugs in the mangler.Peter Collingbourne2013-04-251-13/+19
| | | | | | | | | | | | | | This includes the following fixes: - Implement 4 subtly different variants of qualifier mangling and use them in what I believe are the right places. - Fix handling of array types. Previously we were always decaying them, which is wrong if the type appears as a template argument, pointee, referent etc. Fixes PR13182.
