the declaration chain in search of a definition. This is necessary for a sane chained PCH implementation. No observable performance change on Carbon.h syntax-only, and bootstraps cleanly. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@110051 91177308-0d34-0410-b5e6-96231b3b80d8

2010-08-02Frontend: Change PluginASTAction::ParseArgs to take a CompilerInstance objectDaniel Dunbar
for use in reporting diagnostics. - We don't want to use the Action's own CompilerInstance, because that is only initialized during file processing and I like that invariant. Also, if ParseArgs returns false then abandon execution. Also, remove unused PluginASTAction::PrintHelp virtual method. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@110039 91177308-0d34-0410-b5e6-96231b3b80d8

2010-08-02Driver: Give Build{Universal,}Actions access to the default host tool chain. IDaniel Dunbar
avoided this originally to enforce that the driver actions aren't toolchain dependent, but it isn't worth the cumbersone additional hostinfo split. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@110023 91177308-0d34-0410-b5e6-96231b3b80d8

2010-08-01Driver: Keep track of a separate "install dir", which is the path where clangDaniel Dunbar
was invoked from (which may not be where the executable itself is). - This allows having e.g., /Developer/usr/bin/clang be a symlink to some other location, while still making sure the Driver finds 'as', 'ld', etc. relative to itself. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@109989 91177308-0d34-0410-b5e6-96231b3b80d8

2010-08-01Only run the jump-checker if there's a branch-protected scope *and* there'sJohn McCall
a switch or goto somewhere in the function. Indirect gotos trigger the jump-checker regardless, because the conditions there are slightly more elaborate and it's too marginal a case to be worth optimizing. Turns off the jump-checker in a lot of cases in C++. rdar://problem/7702918 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@109962 91177308-0d34-0410-b5e6-96231b3b80d8

2010-07-31Fix fragile-ABI ObjC exceptions in the presence of optimization withJohn McCall
the magic of inline assembly. Essentially we use read and write hazards on the set of local variables to force flushing locals to memory immediately before any protected calls and to inhibit optimizing locals across the setjmp->catch edge.
