Mikhail Glushenkov 8fedbb7b02 Add a generalised 'case' construct. 
Besides assigning edge weights, it will also be used by the cmd_line tool property.

Nick Kledzik 25368998e7 remove the StripSymbolsPass. This should not be done by default in libLTO.dylib. The linker will remove the symbol names if needed after LTO is done

 2008-05-29 21:57:11 +00:00
Dan Gohman 96af4ddb62 Add patterns for CALL32m and CALL64m. They aren't matched in most 
cases due to an isel deficiency already noted in
lib/Target/X86/README.txt, but they can be matched in this fold-call.ll
testcase, for example.

This is interesting mainly because it exposes a tricky tblgen bug;
tblgen was incorrectly computing the starting index for variable_ops
in the case of a complex pattern.

llvm-svn: 51706
 2008-05-29 21:50:34 +00:00
Bill Wendling 33e396d041 Remove more iostream header includes. Needed to implement a "FlushStream" 
function to flush a specified std::ostream.

Dan Gohman 6e582c449f Fix a tblgen problem handling variable_ops in tblgen instruction 
definitions. This adds a new construct, "discard", for indicating
that a named node in the input matching pattern is to be discarded,
instead of corresponding to a node in the output pattern. This
allows tblgen to know where the arguments for the varaible_ops are
supposed to begin.

This fixes "rdar://5791600", whatever that is ;-).

memmove to a more plausible value, now that it's actually being used.

Owen Anderson fd24ce0a99 Re-enable the newly simplified ADCE. This fixes a regression on 
Dhrystone introduced by its removal.

llvm-svn: 51669
 2008-05-29 08:48:21 +00:00
Owen Anderson 7686b555e2 Replace the old ADCE implementation with a new one that more simply solves 
the one case that ADCE catches that normal DCE doesn't: non-induction variable
loop computations.

This implementation handles this problem without using postdominators.

llvm-svn: 51668
 2008-05-29 08:45:13 +00:00

like.

llvm-svn: 51661
 2008-05-29 00:51:08 +00:00
Bill Wendling 3f6bb2713e Add a flag to indicate that an instruction is as cheap (or cheaper) than a move 
instruction to execute. This can be used for transformations (like two-address
conversion) to remat an instruction instead of generating a "move"
instruction. The idea is to decrease the live ranges and register pressure and
all that jazz.

llvm-svn: 51660
 2008-05-28 22:54:52 +00:00
Bill Wendling 5a83b097ed Check the "isSafeToMove" predicate, which has a series of tests to make sure 
that it's safe to remat an instruction.
