Exception: LLVM shared library not found!
since it's still looking for a library named "LLVM-3.1svn".

the unit tests without installing the LLVM shared library into a

11 years agoRework the rewriting of loads and stores for vector and integer allocas
Chandler Carruth [Tue, 20 Nov 2012 01:12:50 +0000 (01:12 +0000)]
Rework the rewriting of loads and stores for vector and integer allocas
to properly handle the combinations of these with split integer loads
and stores. This essentially replaces Evan's r168227 by refactoring the
code in a different way, and trynig to mirror that refactoring in both
the load and store sides of the rewriting.

Generally speaking there was some really problematic duplicated code
here that led to poorly founded assumptions and then subtle bugs. Now
much of the code actually flows through and follows a more consistent
style and logical path. There is still a tiny bit of duplication on the
store side of things, but it is much less bad.

This also changes the logic to never re-use a load or store instruction
as that was simply too error prone in practice.

I've added a few tests (one a reduction of the one in Evan's original
patch, which happened to be the same as the report in PR14349). I'm

11 years agoCompletely re-work how the Clang driver interprets PIC and PIE options.
Chandler Carruth [Mon, 19 Nov 2012 03:52:03 +0000 (03:52 +0000)]
Completely re-work how the Clang driver interprets PIC and PIE options.

There were numerous issues here that were all entangled, and so I've
tried to do a general simplification of the logic.
1) The logic was mimicing actual GCC bugs, rather than "features". These
   have been fixed in trunk GCC, and this fixes Clang as well. Notably,
   the logic was always intended to be last-match-wins like any other
   flag.
2) The logic for handling '-mdynamic-no-pic' was preposterously unclear.
   It also allowed the use of this flag on non-Darwin platforms where it
   has no actual meaning. Now this option is handled directly based on
   tests of how llvm-gcc behaves, and it is only supported on Darwin.
3) The APIs for the Driver's ToolChains had the implementation ugliness
   of dynamic-no-pic leaking through them. They also had the
   implementation details of the LLVM relocation model flag names
   leaking through.
4) The actual results of passing these flags was incorrect on Darwin in
   many cases. For example, Darwin *always* uses PIC level 2 if it uses
   in PIC level, and Darwin *always* uses PIC on 64-bit regardless of
   the flags specified, including -fPIE. Darwin never compiles in PIE
   mode, but it can *link* in PIE mode.
5) Also, PIC was not always being enabled even when PIE was. This isn't
   a supported mode at all and may have caused some fallout in builds
   with complex PIC and PIE interactions.

The result is (I hope) cleaner and clearer for readers. I've also left
comments and tests about some of the truly strage behavior that is
observed on Darwin platforms. We have no real testing of Windows
platforms and PIC, but I don't have the tools handy to figure that out.
Hopefully others can beef up our testing here.

Unfortunately, I can't test this for every platform. =/ If folks have
dependencies on these flags that aren't covered by tests, they may
break. I've audited and ensured that all the changes in behavior of the
existing tests are intentional and good. In particular I've tried to
make sure the Darwin behavior (which is more suprising than the Linux
behavior) also matches that of 'gcc' on my mac.
