2012-05-04This patch adds a new Clang compiler flag "-gline-tables-only".Alexey Samsonov
It reduces the amount of emitted debug information: 1) DIEs in .debug_info have types DW_TAG_compile_unit, DW_TAG_subprogram, DW_TAG_inlined_subroutine (for opt builds) and DW_TAG_lexical_block only. 2) .debug_str contains only function names. 3) No debug data for types/namespaces/variables is emitted. 4) The data in .debug_line is enough to produce valid stack traces with function names and line numbers.

2012-05-02Fix forwarding of -fpack-struct from driver to CC1, and add a test.James Molloy
-fpack-struct's handling has changed in CC1 (one of only two flags that needed changing) because the driver treats "-fpack-struct" as a boolean flag, and CC1 (did) treat it as an option with a separated value. This change causes -fpack-struct=X to be forwarded correctly to -fpack-struct=X instead of erroneously to "-fpack-struct X" git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@155981 91177308-0d34-0410-b5e6-96231b3b80d8

2012-04-26Fix a long-standing bug where Clang had a different default from GCC onChandler Carruth
Linux and other (non-Darwin) platforms and have it use -fmath-errno by default (for better or worse). Darwin has seen the light here and uses -fno-math-errno by default, this patch preserves that. If any maintainers for a non-Linux platform would also like to opt-in to -fno-math-errno by default, I'm happy to add folks, but we're currently getting buts and misleading comparisons with GCC due to this difference in behavior on Linux at least. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@155607 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

2012-04-06Fix using Clang as a cross compiler installed on a host machine and notChandler Carruth
inside of a sysroot targeting a system+sysroot which is "similar" or "compatible" with the host system. This shows up when trying to build system images on largely compatible hardware as-if fully cross compiled. The problem is that previously we *perfectly* mimiced GCC here, and it turns out GCC has a bug that no one has really stumbled across. GCC will try to look in thy system prefix ('/usr/local' f.ex.) into which it is instaled to find libraries installed along side GCC that should be preferred to the base system libraries ('/usr' f.ex.). This seems not unreasonable, but it has a very unfortunate consequence when combined with a '--sysroot' which does *not* contain the GCC installation we're using to complete the toolchain. That results in some of the host system's library directories being searched during the link. Now, it so happens that most folks doing stuff like this use '--with-sysroot' and '--disable-multilib' when configuring GCC. Even better, they're usually not cross-compiling to a target that is similar to the host. As a result, searching the host for libraries doesn't really matter -- most of the time weird directories get appended that don't exist (no arm triple lib directory, etc). Even if you're cross-compiling from 32-bit to 64-bit x86 or vice-versa, disabling multilib makes it less likely that you'll actually find viable libraries on the host. But that's just luck. We shouldn't rely on this, and this patch disables looking in the system prefix containing the GCC installation if that system prefix is *outside* of the sysroot. For empty sysroots, this has no effect. Similarly, when using the GCC *inside* of the sysroot, we still track wherever it is installed within the sysroot and look there for libraries. But now we can use a cross compiler GCC installation outside the system root, and only look for the crtbegin.o in the GCC installation, and look for all the other libraries inside the system root. This should fix PR12478, allowing Clang to be used when building a ChromiumOS image without polluting the image with libraries from the host system. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@154176 91177308-0d34-0410-b5e6-96231b3b80d8
