Jeff Cohen 4e3aedeaa6 Use ANSI-approved way of getting the value infinity (otherwise VC++ won't compile it)

Reid Spencer 95d8efdfcf Avoid garbage output in the statistics display by ensuring that the 
strings passed to Statistic's constructor are not destructable. The stats
are printed during static destruction and the SimplifyLibCalls module was
getting destructed before the statistics.

Reid Spencer 49fa070401 Add the StrNCmpOptimization which is similar to strcmp. 
Unfortunately, this optimization didn't trigger on any llvm-test tests.

Reid Spencer 8204531db1 Correct the title and the success criteria: strcmp -> strncmp

Reid Spencer 0a23afbedb Add a new test case for the StrNCmpOptimization.

Reid Spencer 2d5c7beebd Implement the fprintf optimization which converts calls like this: 
fprintf(F,"hello") -> fwrite("hello",strlen("hello"),1,F)
  fprintf(F,"%s","hello") -> fwrite("hello",strlen("hello"),1,F)
  fprintf(F,"%c",'x') -> fputc('c',F)

This optimization fires severals times in llvm-test:

Andrew Lenharth c73e633a41 fold fp div by 0 to inf, the way gcc does. This is legal according to the FP spec

 2005-05-02 21:25:47 +00:00
Andrew Lenharth f5d58d1bc3 Remove support for 1.0 style varargs 
amusing of course, because we will have to go back to those semantics soon

Duraid Madina 7acd5d5f06 support multiplication by constant negative integers 
this constmul code is still buggy though, so beware. mul by 7427 is currently
broken, for example. will fix it when I get a moment :)

llvm-svn: 21652
 2005-05-02 07:27:14 +00:00
Duraid Madina 0e73188c10 add support for bools to SELECT, this fixes Prolangs-C/bison from the 
testsuite, however 09-vor is still dead (hopefully for other reasons!)

Tanya Lattner 4d0ee754e3 Fixed bug in searchPath function for finding nodes between two recurrences. 
Changed dependence analyzer to only use dep distances of 2 or less.
This is experimental.

Andrew Lenharth 537332eba8 I was sure I had thought about this and there was a reason it should work. 
But it is entirely possible I am just crazy.

Reid Spencer 4c444fe007 * Don't depend on "guessing" what a FILE* is, just require that the actual 
type be obtained from a CallInst we're optimizing.
* Make it possible for getConstantStringLength to return the ConstantArray
  that it extracts in case the content is needed by an Optimization.
* Implement the strcmp optimization
* Implement the toascii optimization

This pass is now firing several to many times in the following MultiSource
tests:

Applications/Burg      -   7 (strcat,strcpy)
Applications/siod      -  13 (strcat,strcpy,strlen)
Applications/spiff     - 120 (exit,fputs,strcat,strcpy,strlen)
Applications/treecc    -  66 (exit,fputs,strcat,strcpy)
Applications/kimwitu++ -  34 (strcmp,strcpy,strlen)
Applications/SPASS     - 588 (exit,fputs,strcat,strcpy,strlen)
