Jim Laskey 235aeef9e1 Tab interferes with uniqueness. 
NOTE: There doesn't seem to be consistency for whether a leading tab
is present in a section heading.

Reid Spencer 6088f8af16 Implement the -enabled-cbe-printf-a feature. 
llvm-svn: 31462
 2006-11-05 17:09:41 +00:00
Reid Spencer d549edc2cc Add a -disable-cbe-printf-a option so that the output of the C Backend 
stands a chance of being compiled with a non C99 C compiler. The default
is enabled so you must specifically disable this feature if you want the
CBE output compiled with an older C compiler.

Jim Laskey 01c55a50b1 Live local variables are being dropped because the begin or end labels marking 
their scope are being deleted.  Workaround is to widen scope to full function.

Chris Lattner 2959789c92 encode BLR predicate info for the JIT 
llvm-svn: 31450
 2006-11-04 05:42:48 +00:00
Chris Lattner 6be726048e Go through all kinds of trouble to mark 'blr' as having a predicate operand 
that takes a register and condition code.  Print these pieces of BLR the
right way, even though it is currently set to 'always'.

Next up: get the JIT encoding right, then enhance branch folding to produce
predicated blr for simple examples.

Evan Cheng 51733ed4a3 Fixed some spiller bugs exposed by the recent two-address code changes. Now 
there may be other def(s) apart from the use&def two-address operand. We need
to check if the register reuse for a use&def operand may conflicts with another
def. Provide a mean to recover from the conflict if it is detected when the
defs are processed later.
