It's causing hangs on our internal analyzer buildbot. Will restore after investigating. This reverts r173951 / baa7ca1142990e1ad6d4e9d2c73adb749ff50789. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@174069 91177308-0d34-0410-b5e6-96231b3b80d8
2013-01-31Add support for AArch64 target.Tim Northover
In cooperation with the LLVM patch, this should implement all scalar front-end parts of the C and C++ ABIs for AArch64. This patch excludes the NEON support also reviewed due to an outbreak of batshit insanity in our legal department. That will be committed soon bringing the changes to precisely what has been approved. Further reviews would be gratefully received. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@174055 91177308-0d34-0410-b5e6-96231b3b80d8

2013-01-30[analyzer] Make shallow mode more shallow.Anna Zaks
Redefine the shallow mode to inline all functions for which we have a definite definition (ipa=inlining). However, only inline functions that are up to 4 basic blocks large and cut the max exploded nodes generated per top level function in half. This makes shallow faster and allows us to keep inlining small functions. For example, we would keep inlining wrapper functions and constructors/destructors. With the new shallow, it takes 104s to analyze sqlite3, whereas the deep mode is 658s and previous shallow is 209s. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@173958 91177308-0d34-0410-b5e6-96231b3b80d8

2013-01-30[analyzer] Model trivial copy/move ctors with an aggregate bind.Jordan Rose
This is faster for the analyzer to process than inlining the constructor and performing a member-wise copy, and it also solves the problem of warning when a partially-initialized POD struct is copied. Before: CGPoint p; p.x = 0; CGPoint p2 = p; <-- assigned value is garbage or undefined After: CGPoint p; p.x = 0; CGPoint p2 = p; // no-warning This matches our behavior in C, where we don't see a field-by-field copy. <rdar://problem/12305288> git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@173951 91177308-0d34-0410-b5e6-96231b3b80d8

2013-01-30Comment parsing: resolve more named character referencesDmitri Gribenko
This reimplements r173850 with a better approach: (1) use a TableGen-generated matcher instead of doing a linear search; (2) avoid allocations for new strings by converting code points to string iterals with TableGen. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@173931 91177308-0d34-0410-b5e6-96231b3b80d8

2013-01-30Don't warn about Unicode characters in -E mode.Jordan Rose
People use the C preprocessor for things other than C files. Some of them have Unicode characters. We shouldn't warn about Unicode characters appearing outside of identifiers in this case. There's not currently a way for the preprocessor to tell if it's in -E mode, so I added a new flag, derived from the PreprocessorOutputOptions. This is only used by the Unicode warnings for now, but could conceivably be used by other warnings or even behavioral differences later. <rdar://problem/13107323> git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@173881 91177308-0d34-0410-b5e6-96231b3b80d8
2013-01-30Provide a fixit for constexpr non-static data members.David Blaikie
If the member has an initializer, assume it was probably intended to be static and suggest/recover with that. If the member doesn't have an initializer, assume it was probably intended to be const instead of constexpr and suggest that. (if the attempt to apply these changes fails, don't make any suggestion & produce the same diagnostic experience as before. The only case where this can come up that I know of is with a mutable constexpr with an initializer, since mutable is incompatible with static (but it's already incompatible with const anyway)) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@173873 91177308-0d34-0410-b5e6-96231b3b80d8

2013-01-29[ubsan] Implement the -fcatch-undefined-behavior flag using a trappingChad Rosier
implementation; this is much more inline with the original implementation (i.e., pre-ubsan) and does not require run-time library support. The trapping implementation can be invoked using either '-fcatch-undefined-behavior' or '-fsanitize=undefined-trap -fsanitize-undefined-trap-on-error', with the latter being preferred. Eventually, the -fcatch-undefined-behavior' flag will be removed. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@173848 91177308-0d34-0410-b5e6-96231b3b80d8
