Analysis	teach scev to analyze X*4|1 like X*4+c. This allows us to produce:	2006-12-12 02:26:09 +00:00
AsmParser	Hopefully these are the regenerated files	2006-12-08 18:07:09 +00:00
Bytecode	Create the cast constant expression that was read instead of attempting	2006-12-11 23:20:20 +00:00
CodeGen	Tidy up a bit.	2006-12-12 01:32:02 +00:00
Debugger	Don't use <sstream> in Streams.h but <iosfwd> instead.	2006-12-07 23:41:45 +00:00
ExecutionEngine	Change inferred cast creation calls to more specific cast creations.	2006-12-12 01:17:41 +00:00
Linker	Don't use <sstream> in Streams.h but <iosfwd> instead.	2006-12-07 23:41:45 +00:00
Support	Change the implementation of statistic to not need destructors at all.	2006-12-08 20:00:42 +00:00
System	Eliminate "control reaches end of non-void function" warnings.	2006-12-05 17:53:26 +00:00
Target	use MVN to handle small negative constants	2006-12-12 01:03:11 +00:00
Transforms	trunc to integer, not to FP.	2006-12-11 01:17:00 +00:00
VMCore	Implement getIntegerCast and getFPCast for ConstantExpr. These are similar	2006-12-12 00:51:07 +00:00
Makefile	Make some changes suggested by Chris:	2006-05-17 22:55:35 +00:00
