* [CodeGen][ObjC] Remove the leading `l_` from ObjC symbols and makeAkira Hatanaka2019-05-091-2/+2
| | | | | | | | | | | | | | | private symbols in the __DATA segment internal. This prevents the linker from removing the symbol names. Keeping the symbols visible enables tools to collect various information about the symbols, for example, tools that discover whether or not a symbol gets dirtied. rdar://problem/48887111 Differential Revision: https://reviews.llvm.org/D61454 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@360359 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | Silence warnings about no ObjC class root for the types defined for the tests. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@304662 91177308-0d34-0410-b5e6-96231b3b80d8
* CodeGen: fix section names for different file formatsSaleem Abdulrasool2017-06-031-2/+2
| | | | | | | | | This changes the codegen to match the section names according to the ObjC rewriter as well as the runtime. The changes to the test are simply whitespace changes to the section attributes and names and are functionally equivalent (the whitespace is ignored by the linker). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@304661 91177308-0d34-0410-b5e6-96231b3b80d8

* [Objective-c] Stop attaching section "datacoal_nt" to global variables.Akira Hatanaka2016-02-111-3/+3
| | | | | | | | | | | | | | The current macho linker just copies symbols in section datacoal_nt to section data, so it doesn't really matter whether or not section "datacoal_nt" is attached to the global variable. This is a follow-up to r250370, which made changes in llvm to stop putting functions and data in the *coal* sections. rdar://problem/24528611 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@260496 91177308-0d34-0410-b5e6-96231b3b80d8
* Don't manually insert L prefixes.Rafael Espindola2014-11-061-4/+4
| | | | | | Simply marking the symbol private conveys the desire to hide them to LLVM. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@221451 91177308-0d34-0410-b5e6-96231b3b80d8
* Use private linkage for globals we already name with \01L and \01l.Rafael Espindola2014-02-271-2/+2
| | | | | | | | | | | | In llvm the only semantic difference between internal and private is that llvm tries to hide private globals my mangling them with a private prefix. Since the globals changed by this patch already had the magic don't mangle marker, there should be no change in the generated assembly. A followup patch should then be able to drop the \01L and \01l prefixes and let llvm mangle as appropriate. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@202419 91177308-0d34-0410-b5e6-96231b3b80d8
* FileCheck-ify more grep tests with quoted double quotesReid Kleckner2013-04-111-1/+7
| | | | | | | | This required some tedious reordering to match clang's order. Presumably these ObjC tests were generated based on llvm-gcc's output ordering. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@179282 91177308-0d34-0410-b5e6-96231b3b80d8

* Make -fobjc-nonfragile-abi the -cc1 default, since it's theJohn McCall2011-10-021-3/+3
| | | | | | | | | | | | | | | | | | | | | increasingly prevailing case to the point that new features like ARC don't even support the fragile ABI anymore. This required a little bit of reshuffling with exceptions because a check was assuming that ObjCNonFragileABI was only being set in ObjC mode, and that's actually a bit obnoxious to do. Most, though, it involved a perl script to translate a ton of test cases. Mostly no functionality change for driver users, although there are corner cases with disabling language-specific exceptions that we should handle more correctly now. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@140957 91177308-0d34-0410-b5e6-96231b3b80d8

* Teach IR generation how to lazily emit cleanups. This has a lot of advantages,John McCall2010-07-131-1/+1
| | | | | | | | | | | | | | | | | mostly in avoiding unnecessary work at compile time but also in producing more sensible block orderings. Move the destructor cleanups for local variables over to use lazy cleanups. Eventually all cleanups will do this; for now we have some awkward code duplication. Tell IR generation just to never produce landing pads in -fno-exceptions. This is a much more comprehensive solution to a problem which previously was half-solved by checks in most cleanup-generation spots. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@108270 91177308-0d34-0410-b5e6-96231b3b80d8

* IRgen/NeXT: Fix several alignment issues with Objective-C metadata symbols:Daniel Dunbar2010-04-251-0/+12
| | | | | | | | | - Fix some places that had the alignment hard coded. - Use ABI type alignment, not preferred type alignment -- neither of this is exactly right, as we really want the C type alignment as required by the runtime, but the ABI alignment is a more correct choice. This should be equivalent for x86_64, but fixes the alignment for ARM. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@102314 91177308-0d34-0410-b5e6-96231b3b80d8

* Update tests to use %clang_cc1 instead of 'clang-cc' or 'clang -cc1'.Daniel Dunbar2009-12-151-2/+2
| | | | | | | | | - This is designed to make it obvious that %clang_cc1 is a "test variable" which is substituted. It is '%clang_cc1' instead of '%clang -cc1' because it can be useful to redefine what gets run as 'clang -cc1' (for example, to set a default target). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@91446 91177308-0d34-0410-b5e6-96231b3b80d8

- Changed method names to match gcc (categories names still aren't mangled in). - Expose correct name for class and metadata symbols (although -fvisibility=hidden isn't yet correct). - Remove several things from llvm.used that didn't need to be there (I suspect this can still be trimmed). - Don't use asm-prefix extension for _objc_empty_{cache,vtable} (not needed). - Hide EH type class info with -fvisibility=hidden - Change setGlobal[Option]Visibility to not change the visibility of functions with internal linkage. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@68510 91177308-0d34-0410-b5e6-96231b3b80d8
