Douglas Gregor 573c7467df Straw man for instantiation of expressions. Use it to instantiate the 
width of bitfields. 

I'll be burning this down and replacing it with a properly-dispatched
implementation like the one used for types.

Daniel Dunbar 4f495980c4 Add Diagnostic files for Frontend and move a couple errors over. 
- Notably, clang now exits with an error if it can't find a
   file. This flushed out a bug in the CGColorSpace.c test case. :)

Chris Lattner 4147f08e44 Move 3 "(add (select cc, 0, c), x) -> (select cc, x, (add, x, c))" 
related transformations out of target-specific dag combine into the
ARM backend.  These were added by Evan in r37685 with no testcases
and only seems to help ARM (e.g. test/CodeGen/ARM/select_xform.ll).

Add some simple X86-specific (for now) DAG combines that turn things
like cond ? 8 : 0  -> (zext(cond) << 3).  This happens frequently
with the recently added cp constant select optimization, but is a
very general xform.  For example, we now compile the second example
in const-select.ll to:

_test:
        movsd   LCPI2_0, %xmm0
        ucomisd 8(%esp), %xmm0
        seta    %al
        movzbl  %al, %eax
        movl    4(%esp), %ecx
        movsbl  (%ecx,%eax,4), %eax
        ret

instead of:

_test:
        movl    4(%esp), %eax
        leal    4(%eax), %ecx
        movsd   LCPI2_0, %xmm0
        ucomisd 8(%esp), %xmm0
        cmovbe  %eax, %ecx
        movsbl  (%ecx), %eax
        ret

This passes multisource and dejagnu.

Evan Cheng 4465954638 Enable Chris' value propagation change. It make available known sign, zero, one bits information for values that are live out of basic blocks. The goal is to eliminate unnecessary sext, zext, truncate of values that are live-in to blocks. This does not handle PHI nodes yet.

Daniel Dunbar c727e9310d Driver: Tweak option naming/def: 
- Use OPT_ prefix for ids.

 - Reference groups and aliases by shortend id (on the theory that
   this is more readable).

 - Rename the special option ids to more protected names.

Daniel Dunbar a27669f1d8 ccc: Cleanup arguments a bit; we don't need a separate group for 
-fblocks, and there were some duplicate options scattered in.

argument matching some Option::ID.

 2009-03-12 01:36:44 +00:00
Daniel Dunbar 8fa943436b Driver: Add Option::getId and Option::matches taking an option 
identifier; we will want to use the latter in situations where we just
want to check for a match, but not load options unnecessarily.

branch to the same place were being sorted by the
pointer value of the ConstantInt*; changed to sort
by the actual value of the ConstantInt.
