2012-12-04Sort all of Clang's files under 'lib', and fix up the broken headersChandler Carruth
uncovered. This required manually correcting all of the incorrect main-module headers I could find, and running the new llvm/utils/sort_includes.py script over the files. I also manually added quite a few missing headers that were uncovered by shuffling the order or moving headers up to be main-module-headers. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@169237 91177308-0d34-0410-b5e6-96231b3b80d8
2012-11-23Reapply a subset of r167567 to clean up Darwin-specific code for invoking gcc.Bob Wilson
Unlike my previous attempt at this, this patch leaves intact the check for whether clang can handle the input file type, and for non-Darwin toolchains it will invoke gcc for things it cannot handle. For Darwin toolchains, the behavior reported in pr14338 still occurs with this patch, but that is a definite improvement from what happens currently, where it just crashes with an assertion failure. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@168505 91177308-0d34-0410-b5e6-96231b3b80d8
2012-11-21Fix the '-fuse-init-array' option to actually be an option.Chandler Carruth
Previously, this flag to CC1 was never exposed at the clang driver layer, and if you happened to enable it (by being on Android or GCC 4.7 platform), you couldn't *disable* it, because there was no 'no' variant. The whole thing was confusingly implemented. Now, the target-specific flag processing gets the driver arg list, and we use standard hasFlag with a default based on the GCC version and/or Android platform. The user can still pass the 'no-' variant to forcibly disable the flag, or pass the positive variant to clang itself to enable the flag. The test has also been substantially cleaned up and extended to cover these use cases. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@168473 91177308-0d34-0410-b5e6-96231b3b80d8

2012-11-19Enable -fuse-init-array for Android X86/MIPS.Logan Chien
The dynamic linker of Android does not support .ctors/.dtors. We should emit .init_array and .fini_array regardless the gcc version. NOTE: This patch does not affect the ARM backend, because it is required to generate .init_array and .fini_array for program targeting ARM AAPCS and AEABI. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@168309 91177308-0d34-0410-b5e6-96231b3b80d8
2012-11-19Completely re-work how the Clang driver interprets PIC and PIE options.Chandler Carruth
There were numerous issues here that were all entangled, and so I've tried to do a general simplification of the logic. 1) The logic was mimicing actual GCC bugs, rather than "features". These have been fixed in trunk GCC, and this fixes Clang as well. Notably, the logic was always intended to be last-match-wins like any other flag. 2) The logic for handling '-mdynamic-no-pic' was preposterously unclear. It also allowed the use of this flag on non-Darwin platforms where it has no actual meaning. Now this option is handled directly based on tests of how llvm-gcc behaves, and it is only supported on Darwin. 3) The APIs for the Driver's ToolChains had the implementation ugliness of dynamic-no-pic leaking through them. They also had the implementation details of the LLVM relocation model flag names leaking through. 4) The actual results of passing these flags was incorrect on Darwin in many cases. For example, Darwin *always* uses PIC level 2 if it uses in PIC level, and Darwin *always* uses PIC on 64-bit regardless of the flags specified, including -fPIE. Darwin never compiles in PIE mode, but it can *link* in PIE mode. 5) Also, PIC was not always being enabled even when PIE was. This isn't a supported mode at all and may have caused some fallout in builds with complex PIC and PIE interactions. The result is (I hope) cleaner and clearer for readers. I've also left comments and tests about some of the truly strage behavior that is observed on Darwin platforms. We have no real testing of Windows platforms and PIC, but I don't have the tools handy to figure that out. Hopefully others can beef up our testing here. Unfortunately, I can't test this for every platform. =/ If folks have dependencies on these flags that aren't covered by tests, they may break. I've audited and ensured that all the changes in behavior of the existing tests are intentional and good. In particular I've tried to make sure the Darwin behavior (which is more suprising than the Linux behavior) also matches that of 'gcc' on my mac. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@168297 91177308-0d34-0410-b5e6-96231b3b80d8

2012-07-19Force the OS X version to 10.6 for old-style simulator builds.Bob Wilson
The hack of recognizing a -D__IPHONE_OS_VERSION_MIN_REQUIRED option in place of -mios-simulator-version-min leaves the Darwin version unspecified. It can be set separately with -mmacosx-version-min (which makes no sense) or inferred to match the host version (which is unpredictable and usually wrong). This really needs to get cleaned up, but in the meantime, force the OS X version to 10.6 so that the behavior is sane for the iOS simulator.

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
