2012-09-10Wrong crtbegin/crtend pair used for PIE on Android.Evgeniy Stepanov
Android uses the same flavour of crt*.o for PIE and non-PIE executables, and a different one for DSOs. GNU/Linux, on the other hand, uses one set of crt*.o for non-PIE executables, and another for both PIE executables and DSOs. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@163500 91177308-0d34-0410-b5e6-96231b3b80d8

2012-09-02Rename ANDROIDEABI to Android.Logan Chien
Most of the code guarded with ANDROIDEABI are not ARM-specific, and having no relation with arm-eabi. Thus, it will be more natural to call this environment "Android" instead of "ANDROIDEABI".

This improves compatibility with gcc in this regard, and this file generation can be ameliorated with GCOV_PREFIX and GCOV_PREFIX_STRIP. It's also useful if your build directory doesn't specify -o <abspath> and it uses a recursive make structure, so it's not relative to the toplevel.

2012-07-06Implement -Wpedantic and --no-pedantic to complement -Weverything.Ted Kremenek
This patch introduces some magic in tablegen to create a "Pedantic" diagnostic group which automagically includes all warnings that are extensions. This allows a user to suppress specific warnings traditionally under -pedantic used an ordinary warning flag. This also allows users to use #pragma to silence specific -pedantic warnings, or promote them to errors, within blocks of text (just like any other warning). -Wpedantic is NOT an alias for -pedantic. Instead, it provides another way to (a) activate -pedantic warnings and (b) disable them. Where they differ is that -pedantic changes the behavior of the preprocessor slightly, whereas -Wpedantic does not (it just turns on the warnings). The magic in the tablegen diagnostic emitter has to do with computing the minimal set of diagnostic groups and diagnostics that should go into -Wpedantic, as those diagnostics that already members of groups that themselves are (transitively) members of -Wpedantic do not need to be included in the Pedantic group directly. I went back and forth on whether or not to magically generate this group, and the invariant was that we always wanted extension warnings to be included in -Wpedantic "some how", but the bookkeeping would be very onerous to manage by hand. -no-pedantic (and --no-pedantic) is included for completeness, and matches many of the same kind of flags the compiler already supports. It does what it says: cancels out -pedantic. One discrepancy is that if one specifies --no-pedantic and -Weverything or -Wpedantic the pedantic warnings are still enabled (essentially the -W flags win). We can debate the correct behavior here. Along the way, this patch nukes some code in TextDiagnosticPrinter.cpp and CXStoredDiagnostic.cpp that determine whether to include the "-pedantic" flag in the warning output. This is no longer needed, as all extensions now have a -W flag. This patch also significantly reduces the number of warnings not under flags from 229 to 158 (all extension warnings). That's a 31% reduction. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@159875 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

2012-07-03When using -pg targeting OS X 10.8, pass -no_new_main to the linker.Bob Wilson
By default on OS X 10.8, we don't link with a crt1.o file and the linker knows to use _main as the entry point. But, when compiling with -pg, we need to link with the gcrt1.o file, and the linker needs to be told to use the "start" symbol as the entry point. The -no_new_main linker option does that last part. <rdar://problem/11491405> git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@159683 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

2012-06-11Add PPC support for translating gcc-style -mcpu options into LLVM ↵Hal Finkel
-target-cpu options. This functionality is based on what is done on ARM, and enables selecting PPC CPUs in a way compatible with gcc's driver. Also, mirroring gcc (and what is done on x86), -mcpu=native support was added. This uses the host cpu detection from LLVM (which will also soon be updated by refactoring code currently in backend). In order for this to work, the target needs a list of valid CPUs -- we now accept all CPUs accepted by LLVM. A few preprocessor defines for common CPU types have been added. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@158334 91177308-0d34-0410-b5e6-96231b3b80d8
