Ted Kremenek 873db25879 Minor code cleanup: pull variables into scope of 'if' statement, limiting their 
actual lifetime to their logical lifetime.

Ted Kremenek a8a295f2d9 Temporarily disable RegionStore for stack-addr-ps.c, as a new test case reveals 
a case where RegionStore doesn't create symbolic values for the fields of
structs that are passed-by-value.

Dan Gohman cf092389a9 Request LCSSA after LoopSimplify. This fixes a problem in which the 
PassManager was scheduling LCSSA before LoopSimplify, which does not
preserve LCSSA.

Ted Kremenek 55e07efeed Add a FIXME to RegionStore, do some minor code cleanup, and get RegionStore to 
pass misc-ps.m. Currently RegionStore/BasicStore don't do any special reasoning
about clang-style vectors, so we should return UnknownVal (in all cases) when
accessing their values via an array.

Owen Anderson 2a15443aa8 Make the use of const with respect to LLVMContext sane. Hopefully this is the last time, for the 
moment, that I will need to make far-reaching changes.

Douglas Gregor ff6cbdf806 Keep track of more information within the template instantiation stack, e.g., 
by distinguishing between substitution that occurs for template
argument deduction vs. explicitly-specifiad template arguments. This
is used both to improve diagnostics and to make sure we only provide
SFINAE in those cases where SFINAE should apply.

In addition, deal with the sticky issue where SFINAE only considers
substitution of template arguments into the *type* of a function
template; we need to issue hard errors beyond this point, as
test/SemaTemplate/operator-template.cpp illustrates.

Daniel Dunbar aa246cafaa Driver: Improve diagnostics for failed commands. 
- Not all tools give good error messages, and sometimes the tool can fail w/o
   any error (for example, when signalled).

 - We suppress this message when the failing command is the compiler and it
   failed normally (exit code == 1), under the assumption that it gave a good
   diagnostic.

For example, for a linker failure we now get:
--
ddunbar@lordcrumb:tmp$ clang a.c b.c
ld: duplicate symbol _x in /var/folders/cl/clrOX6SaG+moCeRKEI4PtU+++TI/-Tmp-/cc-bXYITq.o and /var/folders/cl/clrOX6SaG+moCeRKEI4PtU+++TI/-Tmp-/cc-6uK4jD.o
clang: error: linker command failed with exit code 1 (use -v to see invocation)
--

For a compiler crash we get:
--
ddunbar@lordcrumb:tmp$ clang t.i
Assertion failed: (CGT.getTargetData().getTypeAllocSizeInBits(STy) == RL.getSize()), function layoutStructFields, file CodeGenTypes.cpp, line 573.
0   clang-cc          0x0000000100f1f1f1 PrintStackTrace(void*) + 38
... stack trace and virtual stack trace follow ...
clang: error: compiler command failed due to signal 6 (use -v to see invocation)
--

But for a regular compilation failure we get the usual:
--
ddunbar@lordcrumb:tmp$ clang c.c
c.c:1:6: error: invalid token after top level declarator
int x
     ^
1 diagnostic generated.
--

 - No test case, not amenable to non-executable testing. :/

 - <rdar://problem/6945613>

Jeffrey Yasskin 1a93330ffa Add a portable strerror*() wrapper, llvm::sys::StrError(). This includes the

Owen Anderson e722976d54 I give up on trying to use reader/writer locks for recursive type refinement. Use a recursive mutex instead, which will (in theory) generate more contention, but is really 
a much more natural fit for what's going on during recursive type refinement.

 2009-07-01 17:00:06 +00:00
Owen Anderson 6773d388aa Add a pointer to the owning LLVMContext to Module. This requires threading LLVMContext through a lot 
of the bitcode reader and ASM parser APIs, as well as supporting it in all of the tools.

Patches for Clang and LLVM-GCC to follow.
