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.

2012-05-02Driver: Turn the default value for -fmath-errno into a proper target hook ↵Benjamin Kramer
and disable it by default on more platforms. For now -fno-math-errno is the default on BSD-derived platforms (Darwin, DragonFlyBSD, FreeBSD, NetBSD, OpenBSD).

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

2012-03-27Move 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
