Evan Cheng 1fc4025a9c More libcall transformations:
printf("%s\n", str) -> puts(str)
printf("%c", c) -> putchar(c)
Also fixed fprintf(file, "%c", c) -> fputc(c, file)

Chris Lattner 0c4aa14deb First baby step towards ppc64 support. This adds a new -march=ppc64 backend
that is currently just like ppc32 :)

Reid Spencer 57e8e38a6f Only print the stack trace if it was requested. Previously, any call into
the Signals module that registered the handlers would cause the stack trace
to be generated. Now, you must explicitly call PrintStackTraceOnErrorSignal
in order for that to happen.

Chris Lattner 4ff6c1646f Teach the local allocator to know that live-in values (e.g. arguments) are
live at function entry.  This prevents it from using arg registers for other
purposes before the arguments are used.

Jim Laskey 3519b87758 Was pointed out that structure alignment and type alignment are not the same
thing.  Doubles still need to be special cased.

Jim Laskey dce07568f2 Alignment of globals has not been quite right. Needed to drop the pointer type
to get the alignment of the element type.

Evan Cheng 55772ccfd6 Instructions with variable operands (variable_ops) can have a number required
operands. e.g.
def CALL32r : I<0xFF, MRM2r, (ops GR32:$dst, variable_ops),
                "call {*}$dst", [(X86call GR32:$dst)]>;
TableGen should emit operand informations for the "required" operands.

Added a target instruction info flag M_VARIABLE_OPS to indicate the target
instruction may have more operands in addition to the minimum required
operands.

Chris Lattner e3abb14503 Use the PotDoms map to memoize 'dominating value' lookup. With this patch,
LCSSA is still the slowest pass when gccas'ing 252.eon, but now it only takes

Owen Anderson 3f8ff0449a Fix a bug that was causing major slowdowns in povray. This was due to LCSSA
not handling PHI nodes correctly when determining if a value was live-out.

This patch reduces the number of detected live-out variables in the testcase
from 6565 to 485.

Owen Anderson 0ac336965e Fix for 2006-06-26-MultipleExitsSingleBlock.
If a single exit block has multiple predecessors within the loop, it will
appear in the exit blocks list more than once.  LCSSA needs to take that into
account so that it doesn't double process that exit block.

Chris Lattner 006b2c6ab9 Fix a problem exposed by the local allocator. CALL instructions are not marked
as using incoming argument registers, so the local allocator would clobber them
between their set and use.  To fix this, we give the call instructions a variable
number of uses in the CALL MachineInstr itself, so live variables understands
the live ranges of these register arguments.
