There were some frustrating problems with the implementation of -Wwrite-strings. First and foremost, once the positive form of the flag was passed, it could never be disabled by passing -Wno-write-strings. Also, the diagnostic engine couldn't in turn use -Wwrite-strings to control diagnostics (as GCC does) because it was essentially hijacked to drive the language semantics. Fix this by giving CC1 a clean '-fconst-strings' flag to enable const-qualified strings in C and ObjC compilations. Corresponding '-fno-const-strings' is also added. Then the driver is taught to introduce '-fconst-strings' in the CC1 command when '-Wwrite-strings' dominates. This entire flag is basically GCC-bug-compatibility driven, so we also match GCC's bug where '-w' doesn't actually disable -Wwrite-strings. I'm open to changing this though as it seems insane. llvm-svn: 130051

Revert r194097: "With this patch -Wwrite-strings is still implemented with the terrible hack of passing -fconst-strings to -cc1" Passing or not a language option based on diagnostic settings is a bad idea, it breaks using a PCH that was compiled with different diagnostic settings. Also add a test case to make sure we don't regress. llvm-svn: 200964

Fix Clang's __DEPRECATED define to be controled by -Wdeprecated. This matches GCC behavior which libstdc++ uses to limit #warning-based messages about deprecation. The machinery involves threading this through a new '-fdeprecated-macro' flag for CC1. The flag defaults to "on", similarly to -Wdeprecated. We turn the flag off in the driver when the warning is turned off (modulo matching some GCC bugs). We record this as a language option, and key the preprocessor on the option when introducing the define. A separate flag rather than a '-D' flag allows us to properly represent the difference between C and C++ builds (only C++ receives the define), and it allows the specific behavior of following -Wdeprecated without potentially impacting the set of user-provided macro flags. llvm-svn: 130055

Add -ffp-contract = { fast | on | off } command line option support. This flag sets the 'fp-contract' mode, which controls the formation of fused floating point operations. Available modes are: - Fast: Form fused operations anywhere. - On: Form fused operations where allowed by FP_CONTRACT. This is the default mode. - Off: Don't form fused operations (in future this may be relaxed to forming fused operations where it can be proved that the result won't be affected). Currently clang doesn't support the FP_CONTRACT pragma, so the 'On' and 'Off' modes are equivalent. llvm-svn: 159794

Add a new flag, -fms-inline-asm, that enables the output of MS-style inline assembly. By default, we don't emit IR for MS-style inline assembly (see r158833 as to why). This is strictly for testing purposes and should not be enabled with the expectation that things will work. This is a temporary flag and will be removed once MS-style inline assembly is fully supported. llvm-svn: 160573

The only useful loop unrolling flag to give realistically is '-fno-unroll-loops'. The option to the backend is even called 'DisableUnrollLoops'. This is precisely the form that Clang *didn't* support. We didn't recognize the flag, we didn't pass it to the CC1 layer, and even if we did we wouldn't use it. Clang only inspected the positive form of the flag, and only did so to enable loop unrolling when the optimization level wasn't high enough. This only occurs for an optimization level that even has a chance of running the loop unroller when optimizing for size. This commit wires up the 'no' variant, and switches the code to actually follow the standard flag pattern of using the last flag and allowing a flag in either direction to override the default. I think this is still wrong. I don't know why we disable the loop unroller entirely *from Clang* when optimizing for size, as the loop unrolling pass *already has special logic* for the case where the function is attributed as optimized for size! We should really be trusting that. Maybe in a follow-up patch, I don't really want to change behavior here. llvm-svn: 187969

Add -freroll-loops to enable loop rerolling This adds -freroll-loops (and -fno-reroll-loops in the usual way) to enable loop rerolling as part of the optimization pass manager. This transformation can enable vectorization, reduce code size (or both). Briefly, loop rerolling can transform a loop like this: for (int i = 0; i < 3200; i += 5) { a[i] += alpha * b[i]; a[i + 1] += alpha * b[i + 1]; a[i + 2] += alpha * b[i + 2]; a[i + 3] += alpha * b[i + 3]; a[i + 4] += alpha * b[i + 4]; } into this: for (int i = 0; i < 3200; ++i) { a[i] += alpha * b[i]; } Loop rerolling is currently disabled by default at all optimization levels. llvm-svn: 194967

Move logic to enable the vectorizer to clang We used to decide whether to really vectorize depending on the optimization level in PassManagerBuilder. This patch moves this decision to the clang driver. We look at the optimization level and whether the f(no-)vectorize is set and decide whether to vectorize. This allows us to simplify the logic in PassManagerBuilder to just a check for whether the vectorizer should run or not. We now do the right thing for: $ clang -O1 -fvectorize $ clang -fno-vectorize -O3 llvm-svn: 188280

Teach Clang to accept and ignore -f[no-]implicit-templates. This GCC flag is useful when you want to control whether implicit template instantiation occurs at the commandline level. Clang doesn't currently support such controls, but technically *always* implicitly instantiating (what Clang does, and what every other compiler still in use does by default) is valid behavior even under -fno-implicit-templates, it just may be slow and very wasteful. If people really want this, we can try to implement it, but I don't have an actual use. This should help fix the build of libstdc++ with Clang, its build system uses this flag. llvm-svn: 193319

Added flags that should be ignored for compatibility. These flags will display a warning. Revision for this patch is here: http://reviews.llvm.org/D4565. This patch will help with the rebuild of Debian with clang and many other projects that wish to use clang. Here is a link to the errors that Debian is experiencing: http://clang.debian.net/status.php?version=3.4.2&key=UNKNOWN_ARG llvm-svn: 214906

GCC compatibility: Create a Group to ignore unsupported optimization. Returns a warning when using an unknown optimization flag. This patch includes -finline-limit as one of those ignored flags.

Fix tests so they work when the linker is gcc If the linker is gcc (the default for Generic_ELF toolchains), we end up passing most of the arguments to the linker.
