Devang Patel 8c78a0bff0 Drop 'const' 
llvm-svn: 36662
 2007-05-03 01:11:54 +00:00
Devang Patel e95c6ad802 Use 'static const char' instead of 'static const int'. 
Due to darwin gcc bug, one version of darwin linker coalesces
static const int, which defauts PassID based pass identification.

Devang Patel 09f162ca6a Do not use typeinfo to identify pass in pass manager.

Chris Lattner 49fa8d2bff Implement a few missing xforms: printf("foo\n") -> puts. printf("x") -> putchar 
printf("") -> noop.  Still need to do the xforms for fprintf.

Reid Spencer 2e54a15943 Prefer non-virtual calls to ConstantInt::isZero over virtual calls to 
Constant::isNullValue() in situations where it is possible.

llvm-svn: 34821
 2007-03-02 00:28:52 +00:00
Reid Spencer 5b0548de77 Use APInt conversion to string so the result is correct regardless of the 
bit width of the ConstantInt being converted.

Chris Lattner a731513406 stop using methods that take vectors. 
llvm-svn: 34205
 2007-02-12 22:56:41 +00:00
Chris Lattner 32ab643df7 Switch ValueSymbolTable to use StringMap<Value*> instead of std::map<std::string, Value*> 
as its main datastructure.  There are many improvements yet to be made, but
this speeds up opt --std-compile-opts on 447.dealII by 7.3%.

llvm-svn: 34193
 2007-02-12 05:18:08 +00:00
Chris Lattner 8d4c36bb40 simplify name juggling through the use of Value::takeName.

Chris Lattner bf6286ba04 Fix Transforms/DeadArgElim/2007-02-07-FuncRename.ll, fallout from PR411. 
This happened because deadargelim now causes VMCore to auto-rename every
function that it hacks arguments out of.  Because it hacks arguments out of
functions in a non-deterministic order, this caused the resultant numbering
to be nondet.  The fix is to just be careful to not rename functions!

llvm-svn: 34005
 2007-02-07 19:31:33 +00:00
Chris Lattner 88051b0fad shrink vmcore by moving symbol table stripping support out of VMCore into 
the one IPO pass that uses it.

 2007-02-07 06:22:45 +00:00
Reid Spencer 557ab15e71 Apply the VISIBILITY_HIDDEN field to the remaining anonymous classes in 
the Transforms library. This reduces debug library size by 132 KB, debug
binary size by 376 KB, and reduces link time for llvm tools slightly.
