* The flag "-coverage-function-names-in-data" is actually backwards -- we doNick Lewycky2013-03-201-2/+2
| | | | | | | | | | emit function names in .gcda files by default, and the flag turns that off! Rename the flag to make it match what it actually does. This keeps the default format compatible with gcc 4.2. Also add a test for this flag. llvm-svn: 177475
* Make clang emit linkage names in debug info for subprograms when coverage infoNick Lewycky2013-03-201-0/+1
| | | | | | | is enabled. Also add a new -test-coverage cc1 flag which makes testing coverage possible and add our first clang-side coverage test. llvm-svn: 177470
* Remove -Wspellcheck and replace it with a diagnostic option.Argyrios Kyrtzidis2013-03-161-0/+1
| | | | | | | Thanks to Richard S. for pointing out that the warning would show up with -Weverything. llvm-svn: 177218

* PR 11326: Lack diagnosic message when ABI conflicts on ARMWeiming Zhao2013-03-051-2/+18
| | | | | | When both Triple and -mabi are used, it may result into conflicting ABI value. llvm-svn: 176531
* Propagate the split dwarf file information through into the backendEric Christopher2013-02-221-0/+1
| | | | | | | | | and through to the debug info in the module. In order to make the testcase a bit more efficient allow the filename to go through compilation for compile and not assemble jobs and turn off the extract for cases where we don't create an object. llvm-svn: 175935
* Comment parsing: add CommentOptions to allow specifying custom comment block ↵Dmitri Gribenko2013-02-221-0/+5
| | | | | | | | | | | | | | | | commands Add an ability to specify custom documentation block comment commands via a new class CommentOptions. The intention is that this class will hold future customizations for comment parsing, including defining documentation comments with specific numbers of parameters, etc. CommentOptions instance is a member of LangOptions. CommentOptions is controlled by a new command-line parameter -fcomment-block-commands=Foo,Bar,Baz. llvm-svn: 175892
* Add -fbracket-depth=N, analogous to -ftemplate-depth= and -fconstexpr-depth=,Richard Smith2013-02-221-0/+1
| | | | | | | | | | | to control the check for the C 5.2.4.1 / C++ [implimits] restriction on nesting levels for parentheses, brackets and braces. Some code with heavy macro use exceeds the default limit of 256, but we don't want to increase it generally to avoid stack overflow on stack-constrained systems. llvm-svn: 175855
* Add support for -fvisibility-ms-compat.John McCall2013-02-191-11/+31
| | | | | | | | | | | | | | | We treat this as an alternative to -fvisibility=<?> which changes the default value visibility to "hidden" and the default type visibility to "default". Expose a -cc1 option for changing the default type visibility, repurposing -fvisibility as the default value visibility option (also setting type visibility from it in the absence of a specific option). rdar://13079314 llvm-svn: 175480

* Introduce -fmodules-ignore-macro=NNN to ignore a macro when building/loading ↵Douglas Gregor2013-02-071-2/+22
| | | | | | | | | | | | | | | | | | | | | modules. The use of this flag enables a modules optimization where a given set of macros can be labeled as "ignored" by the modules system. Definitions of those macros will be completely ignored when building the module hash and will be stripped when actually building modules. The overall effect is that this flag can be used to drastically reduce the number of Eventually, we'll want modules to tell us what set of macros they respond to (the "configuration macros"), and anything not in that set will be excluded. However, that requires a lot of per-module information that must be accurate, whereas this option can be used more readily. Fixes the rest of <rdar://problem/13165109>. llvm-svn: 174560
* [frontend] Don't put a PCH/PTH filename into the set of includes in the ↵Argyrios Kyrtzidis2013-02-051-2/+1
| | | | | | | | | | | | | preprocessor options; since only one of them is allowed in command-line, process them separately. Otherwise, if more than one is specified in the command-line, one is processed normally and the others are going to be treated and included as header files.

* [analyzer] Make shallow mode more shallow.Anna Zaks2013-01-301-1/+0
| | | | | | | | | | | | | | | | 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. llvm-svn: 173958
* [analyzer] Use analyzer config for max-inlinable-size option.Anna Zaks2013-01-301-3/+0

* Don't warn about Unicode characters in -E mode.Jordan Rose2013-01-301-3/+43
| | | | | | | | | | | | | | | 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> llvm-svn: 173881
* [Frontend] Remove HeaderSearchOptions::Entry::IsInternal, which is unused.Daniel Dunbar2013-01-301-2/+1
| | | | llvm-svn: 173866
* [Frontend] Add an ExternCSystem include entry group.Daniel Dunbar2013-01-301-4/+7
| | | | | | | | - The only group where it makes sense for the "ExternC" bit is System, so this simplifies having to have the extra isCXXAware (or ImplicitExternC, depending on what code you talk to) bit caried around. llvm-svn: 173859
* [Frontend] Make the include dir group independent from the "use sysroot" bit.Daniel Dunbar2013-01-291-5/+5
| | | | | | | | | - This slightly decouples the path handling, since before the group sometimes dominated the "use sysroot" bit, but it was still passed in via the API. - No functionality change. llvm-svn: 173855
* [ubsan] Implement the -fcatch-undefined-behavior flag using a trappingChad Rosier2013-01-291-0/+2
| | | | | | | | | | | 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. llvm-svn: 173848
* Enable the global module index by default. Introduce theDouglas Gregor2013-01-281-1/+1
| | | | | | | | -fno-modules-global-index -cc1 option to allow one to disable the index for performance testing purposes, but with a 10% win in -fsyntax-only time, there is no reason a user would do this. llvm-svn: 173707
* [Frontend] Remove another IsUserSpecified member variable that is now unused.Daniel Dunbar2013-01-251-14/+12

| | | | | | | GCC docs. - Found by inspection. llvm-svn: 173410
* Rename the -cc1 option "-generate-module-index" toDouglas Gregor2013-01-251-1/+2
| | | | | | | "-fmodules-global-index" and expand its behavior to include both the use and generation of the global module index. llvm-svn: 173404
* [analyzer] Replace "-analyzer-ipa" with "-analyzer-config ipa".Anna Zaks2013-01-241-16/+0
| | | | | | | | | The idea is to eventually place all analyzer options under "analyzer-config". In addition, this lays the ground for introduction of a high-level analyzer mode option, which will influence the default setting for IPAMode. llvm-svn: 173385
* Implement the writer side of the global module index. Douglas Gregor2013-01-231-1/+2
| | | | | | | | | | | | | | | | | | | | The global module index is a "global" index for all of the module files within a particular subdirectory in the module cache, which keeps track of all of the "interesting" identifiers and selectors known in each of the module files. One can perform a fast lookup in the index to determine which module files will have more information about entities with a particular name/selector. This information can help eliminate redundant lookups into module files (a serious performance problem) and help with creating auto-import/auto-include Fix-Its. The global module index is created or updated at the end of a translation unit that has triggered a (re)build of a module by scraping all of the .pcm files out of the module cache subdirectory, so it catches everything. As with module rebuilds, we use the file system's atomicity to synchronize. llvm-svn: 173301
* Add a new LangOpt NativeHalfType. This option allows for native half/fp16Joey Gouly2013-01-231-0/+1
