Revision 1160 - Directory Listing
Modified Fri Mar 22 14:24:36 2002 UTC (17 years, 5 months ago) by jhr
  New file -- debugging code to check correctness of block placements.

Revision 1157 - Directory Listing
Modified Thu Mar 21 22:33:35 2002 UTC (17 years, 5 months ago) by jhr
  New default block placement that respects edge kinds.

Revision 1156 - Directory Listing
Modified Thu Mar 21 22:01:11 2002 UTC (17 years, 5 months ago) by leunga

     Bug fixes and improvements to x86 and cfg

Revision 1151 - Directory Listing
Modified Mon Mar 18 18:41:31 2002 UTC (17 years, 5 months ago) by jhr
  Fixed flag names for dumping CFG.

Revision 1139 - Directory Listing
Modified Wed Mar 13 18:40:51 2002 UTC (17 years, 5 months ago) by jhr
  Added flags to functor parameters to control hte behavior of the
  algorithm.  The reverseDirection flag is currently a nop.

Revision 1135 - Directory Listing
Modified Tue Mar 12 16:09:26 2002 UTC (17 years, 5 months ago) by jhr
  Added functor to compute block and edge frequencies from edge
  probabilities.

Revision 1134 - Directory Listing
Modified Tue Mar 12 03:59:21 2002 UTC (17 years, 5 months ago) by george
  pick between default and weighted block placement

Revision 1133 - Directory Listing
Modified Tue Mar 12 03:56:23 2002 UTC (17 years, 5 months ago) by george
Tested the jump chain elimination on all architectures (except the
hppa).  This is on by default right now and is profitable for the
alpha and x86, however, it may not be profitable for the sparc and ppc
when compiling the compiler.

The gc test will typically jump to a label at the end of the cluster,
where there is another jump to an external cluster containing the actual
code to invoke gc. This is to allow factoring of common gc invocation
sequences. That is to say, we generate:

	f:
	   testgc
	   ja	L1	% jump if above to L1

	L1:
	   jmp L2


After jump chain elimination the 'ja L1' instructions is converted to
'ja L2'. On the sparc and ppc, many of the 'ja L2' instructions may end
up being implemented in their long form (if L2 is far away) using:

	jbe	L3	% jump if below or equal to L3
        jmp 	L2
     L3:
	...


For large compilation units L2  may be far away.

  Fixed jump chaining bug.  Indentation fixes.

Revision 1126 - Directory Listing
Modified Thu Mar 7 21:16:28 2002 UTC (17 years, 5 months ago) by blume
implemented generic Controls module and used it for
all compiler flags/tuneable knobs/...;
more command-line options accepted (for setting the above controls);
some minor bug fixes

Revision 1125 - Directory Listing
Modified Thu Mar 7 21:04:13 2002 UTC (17 years, 5 months ago) by jhr
