* [CodeGen][ObjC] Remove the leading `l_` from ObjC symbols and makeAkira Hatanaka2019-05-091-9/+9
| | | | | | | | | | | | | | | 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 llvm-svn: 360359
* Use private linkage for globals we already name with \01L and \01l.Rafael Espindola2014-02-271-9/+9
| | | | | | | | | | | | 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. llvm-svn: 202419

| | | | | | | | | | | | | | | | | | | 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. llvm-svn: 140957
* Pack ivar offsets together.Bill Wendling2011-05-041-11/+11
| | | | | | | | | | Ivar offsets for synthesized ivars are wrong, which could end up with a large number of dirty pages because of ivar fixups at runtime. When we pack all of the synthesized ivars into the same section, it limits the number of dirty pages created. Place them in the "__DATA,__objc_ivar" section. <rdar://problem/9374905> llvm-svn: 130870

* Update tests to use %clang_cc1 instead of 'clang-cc' or 'clang -cc1'.Daniel Dunbar2009-12-151-1/+1
| | | | | | | | | - 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). llvm-svn: 91446

* Fix the field count in interface record layout (it was incorrectlyDaniel Dunbar2009-05-041-5/+50
| | | | | | | | | | | | compensating for super classes). This was making the reported class sizes for empty classes very, very wrong. - Also, we now report the size info for an empty class like gcc (as the offset of the start, not as 0, 0). - Add a few more test cases we were mishandling before (padding bit field at end of struct, for example). llvm-svn: 70938
