Nick Lewycky ddc2f9ba57 Clarify the language. Pointed out by Duncan Sands.

Anton Korobeynikov 383a324735 Long live the exception handling! 
This patch fills the last necessary bits to enable exceptions
handling in LLVM. Currently only on x86-32/linux.

In fact, this patch adds necessary intrinsics (and their lowering) which
represent really weird target-specific gcc builtins used inside unwinder.

After corresponding llvm-gcc patch will land (easy) exceptions should be
more or less workable. However, exceptions handling support should not be 
thought as 'finished': I expect many small and not so small glitches
everywhere.

Owen Anderson d975efab16 Handle GEPs with all-zero indices in the same way we handle pointer-pointer bitcasts. Also, fix a potentia infinite loop. 
This brings FastDSE to parity with old DSE on 175.vpr.

llvm-svn: 39825
 2007-07-13 20:08:19 +00:00
Dan Gohman 80f9f077e3 Don't call SimplifyVBinOp for non-vector operations, following earlier review 
feedback. This theoretically makes the common (scalar) case more efficient.

 2007-07-13 20:01:46 +00:00
Owen Anderson 9c9ef21432 Be more aggressive in removing dead stores, and in removing instructions trivially dead after DSE. 
This drastically improves the effect of FastDSE on kimwitu++.

Dale Johannesen 2182f06f2d Skeleton of post-RA scheduler; doesn't do anything yet. 
Change name of -sched option and DEBUG_TYPE to
pre-RA-sched; adjust testcases.

Gabor Greif 42d12da712 these tests do not need a triple on Solaris. Thanks sabre!

Reid Spencer df523644c9 Regenerate to pick up Gabor's changes.

 2007-07-13 10:05:30 +00:00
Gabor Greif f307d942ec * llvm.spec.in: update blurb 
* autoconf/AutoRegen.sh: use variables for autofoo versions
* autoconf/configure.ac: test for some more functions
                         that are not guaranteed on solaris

Note: the svn:mime-type of autoconf/AutoRegen.sh
      should be set to something that allows for
			text compares using svn diff

Owen Anderson 32c4a05dd4 Reimplement removing stores to allocas at the end of a function. This should be safe now.

Owen Anderson d4451dee1e Make the condition-checking for free with non-trivial dependencies more correct. 
llvm-svn: 39789
 2007-07-12 18:08:51 +00:00
Owen Anderson 5e06995b3d Remove the end-block handling code. It was unsafe, and making it safe would have resulted in falling back to the slow DSE case. I need to think some more about the right way to handle this. 
llvm-svn: 39788
 2007-07-12 17:52:20 +00:00
Dale Johannesen 85ee72f7ba ARM: make branch folder remove unconditional branches 
following jump tables that it earlier inserted.  This
would be OK on other targets but is needed for correctness
only on ARM (constant islands needs to find jump tables).

Duncan Sands 0263dd1d7f The type ids making up a filter are unsigned, and 
should be output as unsigned values.  Checked against
gcc.
