| | | | | | | | | | | | | | | | | | | | | Summary: Before when a semicolon was missing after a boolean literal: a = true return 1; clang-format would parse this as one line and format as: a = true return 1; It turns out that C++ does not consider `true` and `false` to be literals, we have to check for that explicitly.

* When replacements have the same offset, make replacements with smaller ↵Eric Liu2016-09-172-9/+8
| | | | | | | | | | | | | | | | | length order first in the set. Summary: No behavioral change intended. The change makes iterating the replacements set more intuitive in Replacements class implementation. Previously, insertion is ordered before an deletion/replacement with the same offset, which is counter-intuitive for implementation, especially for a followup patch to support adding insertions around replacements. With the current ordering, we only need to make `applyAllReplacements` iterate the replacements set reversely when applying them so that deletion/replacement is still applied before insertion with the same offset.

* Alter the iOS/tvOS ARM64 C++ ABI to ignore the upper half of theJohn McCall2016-09-162-2/+48
| | | | | | | | | | | | | | | | | | | | | virtual table offset in a member function pointer. We are reserving this space for future ABI use relating to alternative v-table configurations. In the meantime, continue to zero-initialize this space when actually emitting a member pointer literal. This will successfully interoperate with existing compilers. Future versions of the compiler may place additional data in this location, and at that point, code emitted by compilers prior to this patch will fail if exposed to such a member pointer. This is therefore a somewhat hard ABI break. However, because it is limited to an uncommon case of an uncommon language feature, and especially because interoperation with the standard library does not depend on member pointers, we believe that with a sufficiently advance compiler change the impact of this break will be minimal in practice. llvm-svn: 281693
* Do not warn about format strings that are indexed string literals.Stephen Hines2016-09-162-18/+201
| | | | | | | | | | | | | | | | | | | | | Summary: The warning for a format string not being a string literal and therefore being potentially insecure is overly strict for indices into string literals. This fix checks if the index into the string literal is precomputable. If that's the case it will check if the suffix of that string literal is a valid format string string literal. It will still issue the aforementioned warning for out of range indices into the string literal.

* [CodeGen][ObjC] Block captures should inherit the type of the capturedAkira Hatanaka2016-09-163-11/+67
| | | | | | | | | | | | | | | | | | | | | | | | | | | field in the enclosing lambda or block. This patch fixes a bug in code-gen where it uses the type of the declared variable rather than the type of the capture of the enclosing lambda or block for the block capture. For example, in the following function, code-gen currently uses i32* for the block capture "a" because "a" is passed to foo1 as a reference, but it should use i32 since the enclosing lambda captures "a" by value. void foo1(int &a) { auto lambda = [a]{ auto block1 = ^{ i = a; }; block1(); }; lambda(); } rdar://problem/18586386 Differential Revision: https://reviews.llvm.org/D21104 llvm-svn: 281682

* Simplify Clang's version number configuration in CMake.David L. Jones2016-09-154-42/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, the Clang version is computed as follows: 1. LLVM defines major, minor, and patch versions, all statically set. Today, these are 4, 0, and 0, respectively. 2. The static version numbers are combined into PACKAGE_VERSION along with a suffix, so the result today looks like "4.0.0svn". 3. Clang extracts CLANG_VERSION from PACKAGE_VERSION using a regexp. The regexp allows the patch level to omitted, and drops any non-digit trailing values. Today, this result looks like "4.0.0". 4. CLANG_VERSION is then split further into CLANG_VERSION_MAJOR and CLANG_VERSION_MINOR. Today, these resolve to 4 and 0, respectively. 5. If CLANG_VERSION matches a regexp with three version components, then CLANG_VERSION_PATCHLEVEL is extracted and the CLANG_HAS_VERSION_PATCHLEVEL variable is set to 1. Today, these values are 0 and 1, respectively. 6. The CLANG_VERSION_* variables (and CLANG_HAS_VERSION_PATCHLEVEL) are configured into [llvm/tools/clang/]include/clang/Basic/Version.inc verbatim by CMake. 7. In [llvm/tools/clang/]include/clang/Basic/Version.h, macros are defined conditionally, based on CLANG_HAS_VERSION_PATCHLEVEL, to compute CLANG_VERSION_STRING as either a two- or three-level version number. Today, this value is "4.0.0", because despite the patchlevel being 0, it was matched by regexp and is thus "HAS"ed by the preprocessor. This string is then used wherever Clang's "version" is needed [*]. [*] Including, notably, by compiler-rt, for computing its installation path. This change collapses steps 2-5 by defaulting Clang to use LLVM's (non-string) version components for the Clang version (see [*] for why not PACKAGE_VERSION), and collapses steps 6 and 7 by simply writing CLANG_VERSION_STRING into Version.inc. The Clang version today always uses the patchlevel form, so the collapsed Version.inc does not have logic for a version without a patch level. Historically speaking, this technique began with the VER file in r82085 (which survives in the form of the regexp in #3). The major, minor, and patchlevel versions were introduced by r106863 (which remains in #4-6). The VER file itself was deleted in favor of the LLVM version number in r106914. On the LLVM side, the individual LLVM_VERSION_MAJOR, LLVM_VERSION_MINOR, and PACKAGE_VERSION weren't introduced for nearly two more years, until r150405. llvm-svn: 281666

* [mips][ias] Enable IAS by default for N64 on Debian mips64el.Simon Dardis2016-09-151-0/+7
| | | | | | | | | | | | | | | | | | | Unfortunately we can't enable it for all N64 because it is not yet possible to distinguish N32 from N64 from the triple on other environments. N64 has been confirmed to produce identical (within reason) objects to GAS during stage 2 of compiler recursion on N64-abi Fedora. Unfortunately, Fedora's triples do not distinguish N32 from N64 so I can't enable it by default there. I'm currently repeating this testing for Debian mips64el but it's very unlikely to produce a different result.
