Owen Anderson 5e72db3f7f Add FastDSE, a new algorithm for doing dead store elimination. This algorithm is not as accurate
as the current DSE, but it only a linear scan over each block, rather than quadratic.  Eventually
(once it has been improved somewhat), this will replace the current DSE.

NOTE: This has not yet been extensively tested.

Dan Gohman 60d6f96da3 Change the peep for EXTRACT_VECTOR_ELT of BUILD_PAIR to look for
the new CONCAT_VECTORS node type instead, as that's what legalize
uses now. And add a peep for EXTRACT_VECTOR_ELT of INSERT_VECTOR_ELT.

Evan Cheng 5e9084207f If the operand is marked M_OPTIONAL_DEF_OPERAND, then it's a def.

Evan Cheng fbc73099dc Somehow this wasn't committed last time. M_CLOBBERS_PRED is gone.

Patch by Benoit Boissinot. Thanks, Benoit!

Dan Gohman fa91282dbf Fix the folding of undef in several binary operators to recognize
undef in either the left or right operand.

2007-07-10 14:20:37 +00:00
Reid Spencer 0818f7dbf9 Simplify the handling of the --*flags options. The makefile already gets it
right so there is no need to duplicate logic, just use the values the makefile
provides. 

Eliminate some redundnt -D options from the output.

Fix the help output so it fits on 80 cols.

Reid Spencer 1da59dd6dd Makesure the -cppflags also uses the CPP.BaseFlags as the CPP.Defines only
contains some of the defines but not all CPP flags.

llvm-svn: 38487
2007-07-10 07:21:34 +00:00
Reid Spencer fd8e641c1e Make sure that preprocessor symbols like _DEBUG, NDEBUG, and _GLIBC_DEBUG are
put into the CPP.Defines variable. Seems the convention was corrupted with
various changes made. It is important to get command line parameters into the
right variable because things like llvm-config and sub-makefiles depend on it.

Evan Cheng ff6f279adf When a node value is only used by a CopyToReg, use the user's dest. This should not be restricted to nodes that produce only a single value.

Owen Anderson 7ff09810a8 Evidently my earlier fix did not go far enough. When resizing a zero-sized
BitVector, make sure to set or clear ALL of the bits.

2007-07-10 02:01:16 +00:00
Owen Anderson 4c4b238448 Move some key maps from std::map to DenseMap. This improves the time to optimize Anton's testcase from 17.5s
to 15.7s.

llvm-svn: 38480
2007-07-10 00:27:22 +00:00
Owen Anderson 41c2cab873 Use a cheaper test, delaying calling find_leader() until we know that it's necessary. This improves
the time to optimize Anton's testcase from 21.1s to 17.6s.

2007-07-10 00:09:25 +00:00
Dan Gohman 57111e7a60 Define non-intrinsic instructions for vector min, max, sqrt, rsqrt, and rcp,
in addition to the intrinsic forms. Add spill-folding entries for these new
instructions, and for the scalar min and max instrinsic instructions which
were missing. And add some preliminary ISelLowering code for using the new
non-intrinsic vector sqrt instruction, and fneg and fabs.

llvm-svn: 38478
2007-07-10 00:05:58 +00:00

Owen Anderson effc7a7d16 Take advantage of the new fast SmallPtrSet assignment operator when propagating AVAIL_OUT sets.
This reduces the time to optimize Anton's testcase from 31.2s to 21.s!

llvm-svn: 38475
2007-07-09 22:29:50 +00:00

Dan Gohman f8f531bf69 Change getCopyToParts and getCopyFromParts to always use target-endian
register ordering, for both physical and virtual registers. Update the PPC
target lowering for calls to expect registers for the call result to
already be in target order.
