 2005-09-29 19:29:15 +00:00
Chris Lattner e86824e57a Teach tblgen to build permutations of instructions, so that the target author 
doesn't have to specify them manually.  It currently handles associativity,
e.g. knowing that (X*Y)+Z  also matches  X+(Y*Z)  and will be extended in
the future.

It is smart enough to not introduce duplicate patterns or patterns that can
never match.

Chris Lattner eca4f56646 Make the JIT default to the DAG isel instead of the pattern isel, like LLC. 
The Pattern isel has some strange memory corruption issues going on. :(

This should have been converted over anyway, but it got forgotten somehow
when switching to the dag isel.

Chris Lattner 8bb25cd68a Emit an error if instructions or patterns are defined but can never match. 
Currently we check that immediate values live on the RHS of commutative
operators.  Defining ORI like this, for example:

def ORI   : DForm_4<24, (ops GPRC:$dst, GPRC:$src1, u16imm:$src2),
                    "ori $dst, $src1, $src2",
                    [(set GPRC:$dst, (or immZExt16:$src2, GPRC:$src1))]>;

results in:

tblgen: In ORI: Instruction can never match: Immediate values must be on the RHS of commutative operators!

Chris Lattner a028e7a39c Darwin, like many BSD systems, has a setjmp/longjmp which saves the signal mask 
on setjmp calls and restores it on longjmp calls (both of which require syscalls).

This makes the calls REALLY slow.  Use _setjmp/_longjmp instead.  This speeds up
hexxagon from 120.31s to 15.68s: from 5.53x slower than GCC to 28% faster than GCC.

llvm-svn: 23482
 2005-09-27 22:18:25 +00:00

Chris Lattner 87eb249300 Completely rewrite 'correct' eh support. This changes how setjmp insertion 
is performed so it is only at most once per function that contains an invoke
instead of once per invoke in the function.  This patch has the following perks:

1. It fixes PR631, which complains about slowness.
2. If fixes PR240, which complains about non-volatile vars being live across
   setjmp/longjmps.
3. It improves (but does not fix) the jmpbuf alignment issue on itanium by not
   forcing the jmpbufs to always be 8-bytes off the alignment of the structure.
4. It speeds up 253.perlbmk from 338s to 13.70s (a 25x improvement!), making us
   now about 4% faster than GCC.

Further improvements are also possible.
