2012-08-24[ms-inline asm] Change the -fenable-experimental-ms-inline-asm option from a Chad Rosier
CodeGen option to a LangOpt option. In turn, hoist the guard into the parser so that we avoid the new (and fairly unstable) Sema/AST/CodeGen logic. This should restore the behavior of clang to that prior to r158325. <rdar://problem/12163681> git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@162602 91177308-0d34-0410-b5e6-96231b3b80d8
2012-08-21[analyzer] Set the default IPA mode to 'basic-inlining', which excludes C++.Jordan Rose
Under -analyzer-ipa=basic-inlining, only C functions, blocks, and C++ static member functions are inlined -- essentially, the calls that behave like simple C function calls. This is essentially the behavior in Xcode 4.4. C++ support still has some rough edges, and we don't want users to be worried about them if they download and run their own checker. (In particular, the massive number of false positives for analyzing LLVM comes from inlining defensively-written code in contexts where more aggressive assumptions are implicitly made. This problem is not unique to C++, but it is exacerbated by the higher proportion of code that lives in header files in C++.) The eventual goal is to be comfortable enough with C++ support (and simple Objective-C support) to advance to -analyzer-ipa=inlining as the default behavior. See the IPA design notes for more details. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@162318 91177308-0d34-0410-b5e6-96231b3b80d8

2012-08-08Preprocessor: fix __OPTIMIZE_SIZE__ and -OzDylan Noblesmith
Add some tests for __OPTIMIZE_SIZE__ and __NO_INLINE__, removing the superfluous copies in the target-specific tests, since it's target-independent. This uncovered a bug in the handling of -Oz: it would attempt to store the value 2 in the 1-bit bitfield OptimizeSize, leaving a value of 0 and never defining __OPTIMIZE_SIZE__. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@161495 91177308-0d34-0410-b5e6-96231b3b80d8

2012-07-06Add -ffp-contract = { fast | on | off } command line option support.Lang Hames
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. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@159794 91177308-0d34-0410-b5e6-96231b3b80d8

2012-07-02Add a new libclang completion API to get brief documentation comment that isDmitri Gribenko
attached to a declaration in the completion string. Since extracting comments isn't free, a new code completion option is introduced. A new code completion option that enables including brief comments into CodeCompletionString should be a, err, code completion option. But because ASTUnit caches global declarations during parsing before even completion consumer is created, the option is duplicated as a translation unit option (in both libclang and ASTUnit, like the option to cache code completion results). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@159539 91177308-0d34-0410-b5e6-96231b3b80d8

2012-06-20Restructure how the driver communicates information about theJohn McCall
target Objective-C runtime down to the frontend: break this down into a single target runtime kind and version, and compute all the relevant information from that. This makes it relatively painless to add support for new runtimes to the compiler. Make the new -cc1 flag, -fobjc-runtime=blah-x.y.z, available at the driver level as a better and more general alternative to -fgnu-runtime and -fnext-runtime. This new concept of an Objective-C runtime also encompasses what we were previously separating out as the "Objective-C ABI", so fragile vs. non-fragile runtimes are now really modelled as different kinds of runtime, paving the way for better overall differentiation. As a sort of special case, continue to accept the -cc1 flag -fobjc-runtime-has-weak, as a sop to PLCompatibilityWeak. I won't go so far as to say "no functionality change", even ignoring the new driver flag, but subtle changes in driver semantics are almost certainly not intended. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@158793 91177308-0d34-0410-b5e6-96231b3b80d8

2012-04-08Teach Clang about PIE compilations. This is the first step of PR12380.Chandler Carruth
First, this patch cleans up the parsing of the PIC and PIE family of options in the driver. The existing logic failed to claim arguments all over the place resulting in kludges that marked the options as unused. Instead actually walk all of the arguments and claim them properly. We now treat -f{,no-}{pic,PIC,pie,PIE} as a single set, accepting the last one on the commandline. Previously there were lots of ordering bugs that could creep in due to the nature of the parsing. Let me know if folks would like weird things such as "-fPIE -fno-pic" to turn on PIE, but disable full PIC. This doesn't make any sense to me, but we could in theory support it. Options that seem to have intentional "trump" status (-static, -mkernel, etc) continue to do so and are commented as such. Next, a -pie-level flag is threaded into the frontend, rigged to a language option, and handled preprocessor, setting up the appropriate defines. We'll now have the correct defines when compiling with -fpie. The one place outside of the preprocessor that was inspecting the PIC level (as opposed to the relocation model, which is set and handled separately, yay!) is in the GNU ObjC runtime. I changed it to exactly preserve existing behavior. If folks want to change its behavior in the face of PIE, they can do that in a separate patch. Essentially the only functionality changed here is the preprocessor defines and bug-fixes to the argument management. Tests have been updated and extended to test all of this a bit more thoroughly. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@154291 91177308-0d34-0410-b5e6-96231b3b80d8

2012-03-27Move the emission of strict enum range metadata behind a flag (the sameChandler Carruth
flag as GCC uses: -fstrict-enums). There is a *lot* of code making unwarranted assumptions about the underlying type of enums, and it doesn't seem entirely reasonable to eagerly break all of it. Much more importantly, the current state of affairs is *very* good at optimizing based upon this information, which causes failures that are very distant from the actual enum. Before we push for enabling this by default, I think we need to implement -fcatch-undefined-behavior support for instrumenting and trapping whenever we store or load a value outside of the range. That way we can track down the misbehaving code very quickly. I discussed this with Rafael, and currently the only important cases he is aware of are the bool range-based optimizations which are staying hard enabled. We've not seen any issue with those either, and they are much more important for performance. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@153550 91177308-0d34-0410-b5e6-96231b3b80d8
2012-03-27[analyzer] Add an option to re-analyze a dead-end path without inlining.Anna Zaks
The analyzer gives up path exploration under certain conditions. For example, when the same basic block has been visited more than 4 times. With inlining turned on, this could lead to decrease in code coverage. Specifically, if we give up inside the inlined function, the rest of parent's basic blocks will not get analyzed. This commit introduces an option to enable re-run along the failed path, in which we do not inline the last inlined call site. This is done by enqueueing the node before the processing of the inlined call site with a special policy encoded in the state. The policy tells us not to inline the call site along the path. This lead to ~10% increase in the number of paths analyzed. Even though we expected a much greater coverage improvement. The option is turned off by default for now. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@153534 91177308-0d34-0410-b5e6-96231b3b80d8

Reuse the existing code in Frontend currently used for cc1, adjusting it to not interpret -Wl, linker flags as warnings. Also fix a faulty test exposed by this change. It wasn't actually testing anything, and was giving this warning: clang-3: warning: argument unused during compilation: '-verify' Which -Werror didn't turn into an error because it was output by the driver, not the cc1 process, and diagnostic options weren't parsed by the driver.
