------------------------------------------------------------------------ r181342 | rsmith | 2013-05-07 12:32:56 -0700 (Tue, 07 May 2013) | 4 lines C++1y: Update __cplusplus to temporary value 201305L to allow detection of provisional C++1y support. Add __has_feature and __has_extension checks for C++1y features (based on the provisional names from the C++ features study group), and update documentation to match. ------------------------------------------------------------------------ git-svn-id: https://llvm.org/svn/llvm-project/cfe/branches/release_33@182340 91177308-0d34-0410-b5e6-96231b3b80d8
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

2013-04-17Fix off-by-one error in #pragma clang system_header.Jordan Rose
The system_header pragma (from GCC) is implemented using line notes in the source manager. However, a line note's line number specifies the number not for the current line, but for the next line. This was making all line numbers appear off by one after the pragma. Reported by Andy Gibbs, uncovered during r179677. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@179709 91177308-0d34-0410-b5e6-96231b3b80d8

2013-04-10Improve the diagnostics of the number-reading preprocessor directives.Michael Ilseman
The GNU line marker directive was sharing code with the #line directive, but some of the warnings/errors were reporting as #line directive diagnostics in both cases. Previously: #line 11foo1 ==> "#line directive requires a simple digit sequence" # 11foo1 ==> "#line directive requires a simple digit sequence" Now, we get: #line 11foo1 ==> "#line directive requires a simple digit sequence" # 11foo1 ==> "GNU line marker directive requires a simple digit sequence" git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@179139 91177308-0d34-0410-b5e6-96231b3b80d8
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

2013-04-03[preprocessor] Allow comparing two macro definitions syntactically instead ↵Argyrios Kyrtzidis
of only lexically. Syntactically means the function macro parameter names do not need to use the same identifiers in order for the definitions to be considered identical. Syntactic equivalence is a microsoft extension for macro redefinitions and we'll also use this kind of comparison to check for ambiguous macros coming from modules. rdar://13562254 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@178671 91177308-0d34-0410-b5e6-96231b3b80d8

2013-03-05Preprocessor: don't keep comments under -traditional-cpp.Jordan Rose
This patch is designed for minimal intrusion into normal preprocessing and compilation; under -E -traditional-cpp, the lexer will still generate tok::comment nodes since it is preserving all whitespace, but the output printer will then throw it away. <rdar://problem/13338680> git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@176534 91177308-0d34-0410-b5e6-96231b3b80d8
2013-03-05Preprocessor: don't consider // to be a line comment in -E -std=c89 mode.Jordan Rose
It's beneficial when compiling to treat // as the start of a line comment even in -std=c89 mode, since it's not valid C code (with a few rare exceptions) and is usually intended as such. We emit a pedantic warning and then continue on as if line comments were enabled. This has been our behavior for quite some time. However, people use the preprocessor for things besides C source files. In today's prompting example, the input contains (unquoted) URLs, which contain // but should still be preserved. This change instructs the lexer to treat // as a plain token if Clang is in C90 mode and generating preprocessed output rather than actually compiling. <rdar://problem/13338743> git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@176526 91177308-0d34-0410-b5e6-96231b3b80d8

2013-02-22Preproceessor: fix #if skipping under -traditional-cpp.Jordan Rose
When parsing directives within skipped #if blocks, we don't want to retain any whitespace. Previously we were just skipping comments, but it's not possible to skip comments and retain other whitespace. This change matches the usual behavior for parsing directives (i.e. the behavior outside of skipped #if blocks). <rdar://problem/13267695> git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@175840 91177308-0d34-0410-b5e6-96231b3b80d8
2013-02-21Preprocessor: preserve whitespace in -traditional-cpp mode.Jordan Rose

In cooperation with the LLVM patch, this should implement all scalar front-end parts of the C and C++ ABIs for AArch64.
