2010-09-15build: Start sketching code to allow grafting libc++ build into LLVM/Clang ↵Daniel Dunbar
build if libc++ is checked out into llvm/projects. - WIP, not on by default yet. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@113924 91177308-0d34-0410-b5e6-96231b3b80d8
2010-09-15Disallow the use of UnknownVal as the index for ElementRegions. UnknownVals ↵Ted Kremenek
can be used as the index when the value evaluation isn't powerful enough. By creating ElementRegions with UnknownVals as the index, this gives the false impression that they are the same element, when they really aren't. This becomes really problematic when deriving symbols from these regions (e.g., those representing the initial value of the index), since two different indices will get the same symbol for their binding. This fixes an issue with the idempotent operations checker that would cause two indices that are clearly not the same to make it appear as if they always had the same value. Fixes <rdar://problem/8431728>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@113920 91177308-0d34-0410-b5e6-96231b3b80d8

2010-09-14Introduce a new code-completion context for a parenthesizedDouglas Gregor
expression, e.g., after the '(' that could also be a type cast.

2010-09-14Driver: Add a -stdlib= argument which can be used to select the C++ standardDaniel Dunbar
library to use. - This is currently useful for testing libc++; you can now use 'clang++ -stdlib=libc++ t.cpp' to compile using it if installed. - In the future could also be used to select other standard library choices if alternatives become available (for example, to use an alternate C library). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@113891 91177308-0d34-0410-b5e6-96231b3b80d8

2010-09-13Remove from the CFG the half-implemented support for scoping information. ↵Ted Kremenek

2010-09-13Recognize .ll as input files.Devang Patel
Handle %test_debuginfo on a RUN command line. This set up now allows one to write small test cases to check debug info. e.g. ; RUN: %clang -O0 -g %s -c -o %t.o ; RUN: %clang %t.o -o %t.out ; RUN: %test_debuginfo %s %t.out define i32 @f1(i32 %i) nounwind ssp { ; DEBUGGER: break f1 ; DEBUGGER: r ; DEBUGGER: p i ; CHECK: $1 = 42 entry: %i.addr = alloca i32, align 4 ... ... } It is also possible now to write test cases in c/c++. The plan is to store these debug info testcases in a separate place. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@113780 91177308-0d34-0410-b5e6-96231b3b80d8
